Classes

CBaseEntity

This is a script handle class for entities. All entities have a script handle using this class, sometimes as one of its subclasses.

An entity's own handle are accessed with:

Entities ↓ instance.
EntIndexToHScript function.
Entity Scripts only - The self keyword.

Methods

Function	Signature	Description
`__KeyValueFromFloat (→ KeyValueFromFloat)`	`bool __KeyValueFromFloat(string key, float value)`	Behaves the same as `KeyValueFromFloat`, use that instead.
`__KeyValueFromInt (→ KeyValueFromInt)`	`bool __KeyValueFromInt(string key, int value)`	Behaves the same as `KeyValueFromInt`, use that instead.
`__KeyValueFromString (→ KeyValueFromString)`	`bool __KeyValueFromString(string key, string value)`	Behaves the same as `KeyValueFromString`, use that instead.
`__KeyValueFromVector (→ KeyValueFromVector)`	`bool __KeyValueFromVector(string key, Vector value)`	Behaves the same as `KeyValueFromVector`, use that instead.
`AcceptInput`	`bool AcceptInput(string input, string param, handle activator, handle caller)`	Generate a synchronous I/O event. Unlike `EntFireByHandle`, this is processed immediately. Returns false if input is a null/empty string, or if the input wasn't handled.
`AddEFlags`	`void AddEFlags(int flags)`	Adds the supplied flags to the Entity Flags in the entity. (m_iEFlags datamap) See Constants.FEntityEFlags. Note:Adding `EFL_KILLME` will make the entity unkillable, even on round resets, until the flag is removed.
`AddFlag`	`void AddFlag(int flags)`	Adds the supplied flags to another separate player-related entity flags system in the entity. (m_fFlags datamap) See Constants.FPlayer.
`AddSolidFlags`	`void AddSolidFlags(int flags)`	Adds the supplied flags to the Solid Flags in the entity. (m_Collision.m_usSolidFlags datamap) See Constants.FSolid.
`ApplyAbsVelocityImpulse`	`void ApplyAbsVelocityImpulse(Vector impulse)`	Apply a Velocity Impulse as a world space impulse vector. Works for most physics-based objects including dropped weapons and even dropped Sandviches.
`ApplyLocalAngularVelocityImpulse`	`void ApplyLocalAngularVelocityImpulse(Vector impulse)`	Apply an Angular Velocity Impulse in entity local space. The direction of the input vector is the rotation axis, and the length is the magnitude of the impulse.
`BecomeRagdollOnClient`	`bool BecomeRagdollOnClient(Vector impulse)`	Acts like the `BecomeRagdoll` input, with the required impulse value applied as a force on the ragdoll. Does NOT spawn a `prop_ragdoll` or any other entity. Warning:These are a special group of ragdolls that never disappear by default. To limit them or force them to disappear, use the game_ragdoll_manager entity.
`ClearFlags`	`void ClearFlags()`	Sets the player-related entity flags to 0 on an entity, clearing them.
`ClearSolidFlags`	`void ClearSolidFlags()`	Sets Solid Flags to 0 on an entity, clearing them.
`ConnectOutput`	`void ConnectOutput(string output, string function)`	Adds an I/O connection that will call the named function when the specified output fires. Note:If you are trying to access `activator` and `caller` in the called function and it doesn't exist, this means the entity has no script scope. Use `ValidateScriptScope` to fix this.
`Destroy`	`void Destroy()`	Removes the entity. Simply calls UTIL_Remove.
`DisableDraw`	`void DisableDraw()`	Disable drawing and transmitting the entity to clients. (adds EF_NODRAW)
`DisconnectOutput`	`void DisconnectOutput(string output, string function)`	Removes a connected script function from an I/O event.
`DispatchSpawn`	`void DispatchSpawn()`	Alternative dispatch spawn, same as the one in CEntities, for convenience. Note:Calling this on players will cause them to respawn.
`EmitSound`	`void EmitSound(string soundname)`	Plays a sound from this entity. The sound must be precached first for it to play (using `PrecacheSound` or `PrecacheScriptSound`). Warning:Looping sounds will not stop on the entity when it's destroyed and will persist forever! To workaround this, run `StopSound` in the `OnDestroy` callback.
`EnableDraw`	`void EnableDraw()`	Enable drawing and transmitting the entity to clients. (removes EF_NODRAW)
`entindex`	`int entindex()`	Returns the entity index.

`GetAngularVelocity`	`Vector GetAngularVelocity()`	Get the local angular velocity - returns a Vector of pitch, yaw, and roll.
`GetBaseVelocity`	`Vector GetBaseVelocity()`	Returns any constant velocity currently being imparted onto the entity. This includes being pushed by effects like `trigger_push` and players standing on moving geometry like elevators. Should always returns a zero vector if the entity is not affected by any movement effects.
`GetBoundingMaxs`	`Vector GetBoundingMaxs()`	Get a vector containing max bounds, centered on object
`GetBoundingMaxsOriented`	`Vector GetBoundingMaxsOriented()`	Get a vector containing max bounds, centered on object, taking the object's orientation into account Bug:This does not transform the bounds correctly and in some cases the bounding box will not cover the whole entity. As a workaround, use the non-oriented bounds and perform an AABB transformation using a matrix constructed from the entity's origin and angles. [todo tested in?]
`GetBoundingMins`	`Vector GetBoundingMins()`	Get a vector containing min bounds, centered on object
`GetBoundingMinsOriented`	`Vector GetBoundingMinsOriented()`	Get a vector containing min bounds, centered on object, taking the object's orientation into account Bug:This does not transform the bounds correctly and in some cases the bounding box will not cover the whole entity.

Todo: Actor model name is likely a leftover from Half-Life 2 Warning:Does not work on dedicated servers as they do not have audio libraries built-in to load sounds.
`GetTeam`	`int GetTeam()`
`GetUpVector`	`Vector GetUpVector()`	Get the up vector of the entity
`GetVelocity (→ GetAbsVelocity)`	`Vector GetVelocity()`
`GetWaterLevel`	`int GetWaterLevel()`	This function tells you how much of the entity is underwater. It returns a value of 0 if not underwater, 1 if the feet are (touching water brush), 2 if the waist is (center of the hull of the entity), and 3 if the head is (eyes position). Note:Some entities might not return 1 despite touching water. In some cases you might get 0 and 3 only, or sometimes 0, 2 and 3.

`IsAlive`	`bool IsAlive()`	Am I alive?
`IsEFlagSet`	`bool IsEFlagSet(int eflag)`
`IsPlayer`	`bool IsPlayer()`	Checks whether the entity is a player or not.
`IsSolid`	`bool IsSolid()`
`IsSolidFlagSet`	`bool IsSolidFlagSet(int solidflag)`
`IsValid`	`bool IsValid()`	Checks whether the entity still exists. Useful when storing entity handles and needing to check if the entity was not deleted. Note:This function is never necessary to call on handles returned from built-in script functions, as they are guaranteed to be valid or `null`.
`KeyValueFromFloat`	`bool KeyValueFromFloat(string key, float value)`	Executes KeyValue with a float Warning:Does not update the internal network state of the entity, which can result in any desired visual changes being delayed for clients if used after spawning. Netprops ↓ can be used instead which correctly updates the networking state and results in an immediate update. An exception is the `origin` keyvalue, which does update network state immediately.
`KeyValueFromInt`	`bool KeyValueFromInt(string key, int value)`	Executes KeyValue with an int Warning:See above.
`KeyValueFromString`	`bool KeyValueFromString(string key, string value)`	Executes KeyValue with a string Warning:See above.
`KeyValueFromVector`	`bool KeyValueFromVector(string key, Vector value)`	Executes KeyValue with a vector Warning:See above.
`Kill`	`void Kill()`	Removes the entity. Equivalent of firing the `Kill` I/O input, but instantaneous. Warning:This clears the owner entity (`m_hOwnerEntity` netprop) before removing, this may cause unexpected problems with entities that rely on cleaning up data related to their owner, such as Medigun healing targets. In those cases, use `Destroy` instead.
`LocalEyeAngles`	`handle LocalEyeAngles()`	Returns the entity's local eye angles
`NextMovePeer`	`handle NextMovePeer()`	Returns the next entity parented with the entity. Intended for iteration use with `FirstMoveChild()`.
`PrecacheModel`	`void PrecacheModel(string modelname)`	Precache a model (`.mdl`) or sprite (`.vmt`). The extension must be specified. Note:This has no return, unlike the global `PrecacheModel` function. Use the latter if you need the model index. Note:Does not precache gibs. See `PrecacheEntityFromTable` instead.
`PrecacheScriptSound`	`void PrecacheScriptSound(string soundscript)`	Precache a sound script. Same as `PrecacheSoundScript`.
`PrecacheSoundScript`	`void PrecacheSoundScript(string soundscript)`	Precache a sound script. Same as `PrecacheScriptSound`.

`SetAbsVelocity`	`void SetAbsVelocity(Vector velocity)`	Sets the current absolute velocity of the entity. Does nothing on VPhysics objects (such as `prop_physics`). For those, use `SetPhysVelocity` instead.
`SetAbsOrigin`	`void SetAbsOrigin(Vector origin)`	Sets the absolute origin of the entity. Note:On some entities, this won't interpolate positions and therefore moving entities might look jittery. In those cases, use `KeyValueFromVector("origin", pos)` instead.
`SetAngles (→ SetAbsAngles)`	`void SetAngles(float pitch, float yaw, float roll)`	Set entity angles.
`SetAngularVelocity`	`void SetAngularVelocity(float pitch, float yaw, float roll)`	Set the local angular velocity.
`SetCollisionGroup`	`void SetCollisionGroup(int collision_group)`	Set the current collision group of the entity. See Constants.ECollisionGroup

`SetForwardVector`	`void SetForwardVector(Vector forward)`	Set the orientation of the entity to have this forward vector
`SetFriction`	`void SetFriction(float friction)`
`SetGravity`	`void SetGravity(float gravity)`	Sets a multiplier for gravity. 1 is default gravity. Note:0 gravity will not work. Instead, set it to something like `0.000001` as a workaround
`SetHealth`	`void SetHealth(int health)`
`SetLocalAngles`	`void SetLocalAngles(QAngle angles)`
`SetLocalOrigin`	`void SetLocalOrigin(Vector origin)`
`SetMaxHealth`	`void SetMaxHealth(int health)`	Sets the maximum health this entity can have. Does not update the current health, so `SetHealth` should be used afterwards. Note:Does nothing on players. Add the `max health additive bonus` attribute via `AddCustomAttribute` instead.
`SetModel`	`void SetModel(string model_name)`	Set a model for this entity. Note:Does nothing on players. Use `SetCustomModel` in that case. Warning:Make sure the model was already precached before using this function or otherwise the game will crash! Alternatively, `SetModelSimple` will precache the entity for you.
`SetMoveType`	`void SetMoveType(EMoveType movetype, EMoveCollide movecollide)`
`SetOrigin (→ SetAbsOrigin)`	`void SetOrigin(Vectororigin)`
`SetOwner`	`void SetOwner(handle entity)`	Sets this entity's owner

`SetPhysVelocity`	`void SetPhysVelocity(Vector velocity)`
`SetSize`	`void SetSize(Vector mins, Vector maxs)`	Sets the bounding box's scale for this entity. Warning:If any component of mins/maxs is backwards (i.e. mins.x > maxs.x), the engine will exit with a fatal error.
`SetSolid`	`void SetSolid(int solid)`
`SetSolidFlags`	`void SetSolidFlags(int solid_flags)`
`SetTeam`	`void SetTeam(int team)`	Sets entity team. Note:Use `ForceChangeTeam` on players instead.
`SetVelocity (→ SetAbsVelocity)`	`void SetVelocity(Vector velocity)`
`SetWaterLevel`	`void SetWaterLevel(int water_level)`	This sets how much of the entity is underwater. Setting it to 0 means it is not underwater, 1 if the feet are (touching water brush), 2 if the waist is (center of the hull of the entity), and 3 if the head is (eyes position).
`SetWaterType`	`void SetWaterType(int water_type)`	Set the type of water the entity is currently submerged in. Generic values to use are 32 for water and 16 for slime.
`StopSound`	`void StopSound(string sound_name)`	Stops a sound on this entity.
`TakeDamage`	`void TakeDamage(float flDamage, Constants.FDmgType nDamageType, handle hAttacker)`	Deals damage to the entity.
`TakeDamageEx`	`void TakeDamageEx(handle hInflictor, handle hAttacker, handle hWeapon, Vector vecDamageForce, Vector vecDamagePosition, float flDamage, Constants.FDmgType nDamageType)`	Extended version of `TakeDamage`. Note:If vecDamageForce is Vector(0, 0, 0), the game will automatically calculate it from vecDamagePosition and flDamage. However, specifying a custom damage force requires a really, really big value to have visible effect (in the hundreds of thousands).
`TakeDamageCustom`	`void TakeDamageCustom(handle hInflictor, handle hAttacker, handle hWeapon, Vector vecDamageForce, Vector vecDamagePosition, float flDamage, Constants.FDmgType nDamageType, Constants.ETFDmgCustom nCustomDamageType)`	Extended version of `TakeDamageEx` that can apply a custom damage type.
`Teleport`	`void Teleport(bool use_origin, Vector origin, bool use_angles, QAngle angles, bool use_velocity, Vector velocity)`	Teleports this entity. For this function, set the bools to false if you want that entity's property unchanged. (do not use null arguments!)
`TerminateScriptScope`	`void TerminateScriptScope()`	Clear the current script scope for this entity
`ToggleFlag`	`void ToggleFlag(int flags)`
`ValidateScriptScope`	`bool ValidateScriptScope()`	Create a script scope for an entity if it doesn't already exist. The return value is always returns true, unless the script VM is disabled in launch options. Tip:On players, this only needs to be called once. Script scopes remain permanent on players until their entity is removed, i.e. disconnected. The best place to call this is in the `player_spawn` event when `params.team` equals 0 (unassigned). The event is always fired once for team unassigned when the player entity spawns. Similarly, for engineer buildings, this function can also be called once. The `player_builtobject` is fired when an engineer building is created (or re-placed after moving, but this shouldn't matter).

Hooks

Hooks are functions that are called by the game code at appropriate moments. For example, when an entity takes damage, the OnTakeDamage hook would be executed.

Function Signature Description

Input<name>

bool Input<name>()

Called right before an entity receives a valid input from the I/O system that matches the function's name. The name of the function needs to beInputfollowed by the name of the input. E.g. for the FireUser1 input, it would beInputFireUser1. When the function is called, Script Handles of the activator and caller entities are accessible to the function under the variablesactivatorandcaller. The function needs to return a boolean value; Returningtrueprocesses the input, whilefalsecancels it.

Bug:There is an inconsistency with the naming scheme of the inputs. Certain inputs are required in PascalCase format, others in lowercase format. For example, ForceDrop input on item_teamflag must be specified in lowercase, i.e. Inputforcedrop, but another input such as Kill input must be in PascalCase, i.e. InputKill. However, this inconsistency also varies between different entity classes as well. The cause of this is string caching in the game (I/O is case-insensitive so it normally doesn't matter, but Squirrel is case-sensitive). [todo tested in?]

Tip:It is best to define both variants of these function and have one be a wrapper for the other, i.e. Inputfireuser1 <- InputFireUser1.

Tip:This hook is fired before the game processes the input internally. If a hook is required that runs after the game processes it, there is two options:

Asynchronous: Use a EntFire with a 0 delay to run code at the end of the frame. This is not instantly executed which may cause issues if multiple inputs get processed at once.
Synchronous: Using a quirk, it's possible to synchronously detect when the input has been processed. The game wipes the activator and caller variables from the root table after processing an input. A metamethod that overrides the slot deletion operator can be used to detect this. The following example demonstrates a system to conveniently define pre- and post- input hooks using a SetInputHook function:

// Implementation

::_PostInputScope <- null
::_PostInputFunc  <- null

::SetInputHook <- function(entity, input, pre_func, post_func)
{
        entity.ValidateScriptScope()
	local scope = entity.GetScriptScope()
	if (post_func)
	{
		local wrapper_func = function() 
		{ 
			_PostInputScope = scope
			_PostInputFunc  = post_func
			if (pre_func)
				return pre_func.call(scope)
			return true
		}
		
		scope["Input" + input]           <- wrapper_func
		scope["Input" + input.tolower()] <- wrapper_func // workaround for case bug
	}
	else if (pre_func)
	{
		scope["Input" + input]           <- pre_func
		scope["Input" + input.tolower()] <- pre_func // workaround for case bug
	}
}

getroottable().setdelegate(
{
	_delslot = function(k)
	{
		if (_PostInputScope && k == "activator" && "activator" in this)
		{
			_PostInputFunc.call(_PostInputScope)
			_PostInputFunc = null
		}
		
		rawdelete(k)
	}
})

// Example that hooks the RunScriptCode input on worldspawn

function PreInputRunScriptCode()
{
	printl("INPUT PRE: RunScriptCode")
	printl("\tself: " + self)
	printl("\tactivator: " + activator)
	return true
}

function PostInputRunScriptCode()
{
	printl("INPUT POST: RunScriptCode")
	printl("\tself: " + self)
	printl("\tactivator: " + activator)
}

local world = Entities.FindByClassname(null, "worldspawn")
SetInputHook(world, "RunScriptCode", PreInputRunScriptCode, PostInputRunScriptCode)

EntFire("worldspawn", "RunScriptCode", "printl(`RunScriptCode executed`)", 0, GetListenServerHost())

OnGameEvent_<name>

void OnGameEvent_<name>(table params)

Called each time a game event with the specified name occurs. The name of the function needs to be OnGameEvent_ followed by the name of the game event. E.g. for the player_spawn input, it would be OnGameEvent_player_spawn.

When the function is called, a table is passed to the function with keys that vary depending on the event. For example, the player_spawn event passes a table with the keys userid, team, class, while the deadringer_cheat_death event passes a table with the keys spy, attacker.

A call to __CollectGameEventCallbacks is required to register this hook. See the examples page.

See this page for a list of game events as well as the table passed on each event.

Precache

void Precache()

Entity function that is called after the script executes, but before the entity is initialized. Can be used to call precache functions for models and sounds on map load.

Tip:This can also be used to modify keyvalues on the entity, and it will use the new values when initializing.

ConnectOutputs

void ConnectOutputs(handle scope)

Global function called after an entity with an script assigned spawns (i.e. vscripts keyvalue is not blank). Unlike OnPostSpawn, this is called immediately and therefore on map respawn, some entities may not exist during this point.

Note:This is a global hook and therefore will only work in global scope, unlike Precache and OnPostSpawn.

OnPostSpawn void OnPostSpawn() Entity function called after the entity is spawned and initialized, at the end of the frame. When map entities are respawned, this effectively runs after all scripts, players etc have been loaded. This could be used to have an entity register itself with a master script, or adjusting the entity parameters in a programmatic way.

OnScriptHook_OnTakeDamage

void OnScriptHook_OnTakeDamage(handle params)

Called each time an entity takes damage. The script can modify the table entries not prefixed with const, and these will be sent back to the game code.

A call to __CollectGameEventCallbacks is required to register this hook. Internally, this hook is processed the same as a game event, but with the OnScriptHook prefix instead of OnGameEvent. Therefore, see the example page for an explanation of how to register the hook. Example:

local EventsID = UniqueString()
getroottable()[EventsID] <-
{
    OnScriptHook_OnTakeDamage = function(params)
    {
		printl("OnScriptHook_OnTakeDamage")
		if (params.const_entity.IsPlayer())
		{
			printl(params)
			params.damage = 0
		}
    }

    // Cleanup events on round restart
    OnGameEvent_scorestats_accumulated_update = function(_) { delete getroottable()[EventsID] }
}
local EventsTable = getroottable()[EventsID]
foreach (name, callback in EventsTable) EventsTable[name] = callback.bindenv(this)
__CollectGameEventCallbacks(EventsTable)

Note:The world entity (brushes, static props etc) will not trigger this function by default as it normally can't 'receive' damage. However, the world can be made to 'allow' damage using the following code: NetProps.SetPropInt(Entities.FindByClassname(null, "worldspawn"), "m_takedamage", 1). This does not appear to have any adverse side effects, and allows detecting when the world has been hit.

Note:If called where the damage source is a player's hitscan weapon, player positions or angles fetched within the lag compensation "cone" of the attacker will be using lag compensated positions rather than their real positions.

Note:Drowning damage does not trigger this hook. As a workaround, it can be detected in player_hurt event or disabled by setting m_PainFinished netprop to a very high value.

Warning:This is called before any actual damage processing is done. Certain entries might not be calculated or have different values compared to what will be calculated.

Tip:Listen for the player_hurt or npc_hurt (nextbots) event to effectively have an OnTakeDamage callback after final damage calculations are done.

Tip:DMG_ACID is set in damage_type for critical damage, and DMG_SLOWBURN for falloff. These flags can be toggled to add/remove crits or falloff respectively.

Tip:The hitbox that got hit can be retrieved using the m_LastHitGroup netprop on player entities or generic_actor. The number corresponds to Constants.EHitGroup

The table contains the following keys:

Name	Type	Description
`const_entity`	`handle`	The entity which took damage
`inflictor`	`handle`	The entity which dealt the damage, can be null
`weapon`	`handle`	The weapon which dealt the damage, can be null

`damage`	`float`	Damage amount
`max_damage`	`float`	Damage cap
`damage_bonus`	`float`	Additional damage (e.g. from crits) Warning:Always 0 because this hook is run before this is calculated.
`damage_bonus_provider`	`handle`	Owner of the damage bonus Warning:Always 0 because this hook is run before this is calculated.

`force_friendly_fire`	`bool`	If true, force the damage to friendlyfire, regardless of this entity's and attacker's team Note:Hitscan/melee will not run OnTakeDamage unless the `mp_friendlyfire` convar is set to 1.
`ammo_type`	`int`	Unused
`player_penetration_count`	`int`	How many players the damage has penetrated so far
`damaged_other_players`	`int`	How many players other than the attacker has the damage been applied to. Used for rocket jump damage reduction
`crit_type`	`int`	Type of crit damage. 0 - None, 1 - Mini, 2 - Full Warning:Always 0 because this hook is run before this is set. Instead, check `DMG_ACID` in `damage_type`, which is set when the shot will be critical.
`early_out`	`bool`	If set to true by the script, the game's damage routine will not run and it will simply return the currently set damage.

Callbacks

OnDestroy

It is possible to setup an asynchronous hook which is fired when the entity is deleted, as shown below. It is processed at the end of the frame after the entity's own destroy callback, but before the entity is about to be removed from memory. The caveats are that it is not possible to rescue an entity nor its children in this callback, and the targetname of the entity is cleared (this can be workarounded by storing the name in the script scope if needed). A useful application of this hook is to stop looping sounds on an entity so they don't persist.

// Implementation
function SetDestroyCallback(entity, callback)
{
	entity.ValidateScriptScope()
	local scope = entity.GetScriptScope()
	scope.setdelegate({}.setdelegate({
			parent   = scope.getdelegate()
			id       = entity.GetScriptId()
			index    = entity.entindex()
			callback = callback
			_get = function(k)
			{
				return parent[k]
			}
			_delslot = function(k)
			{
				if (k == id)
				{
					entity = EntIndexToHScript(index)
					local scope = entity.GetScriptScope()
					scope.self <- entity
					callback.pcall(scope)
				}
				delete parent[k]
			}
		})
	)
}

// Example
local entity = SpawnEntityFromTable("prop_dynamic", 
{
	model = "models/player/heavy.mdl"
	origin = Vector(1, 2, 3)
})

SetDestroyCallback(entity, function()
{
	printf("Entity %s at %s was destroyed\n", self.GetClassname(), self.GetOrigin().ToKVString())
})

Note:All handles to the entity are destroyed when inside the callback. You must access the entity by using self only.

Alternatively: if entities need to be rescued from a deletion on a round restart, for example a player parented to a vehicle, the scorestats_accumulated_update event can be used. This event is fired on round restart right before all entities are removed. Add the EFL_KILLME eflag to the entities to rescue, then remove it after entities have spawned.

CBaseAnimating

Extends CBaseEntity ↑

Script handle class for animatable entities, such as props.

Methods

Function	Signature	Description
`DispatchAnimEvents`	`void DispatchAnimEvents(handle entity)`	Dispatch animation events to a CBaseAnimating entity.
`FindBodygroupByName`	`int FindBodygroupByName(string name)`	Find a bodygroup ID by name. Returns -1 if the bodygroup does not exist.
`GetAttachmentAngles`	`QAngle GetAttachmentAngles(int ID)`	Get an attachment's angles as a QAngle, by ID.
`GetAttachmentBone`	`int GetAttachmentBone(int ID)`	Get an attachment's parent bone index by ID.
`GetAttachmentOrigin`	`Vector GetAttachmentOrigin(int ID)`	Get an attachment's origin as a Vector, by ID.
`GetBodygroup`	`int GetBodygroup(int ID)`	Get the bodygroup value by bodygroup ID.
`GetBodygroupName`	`string GetBodygroupName(int ID)`	Get the bodygroup's name by ID.
`GetBodygroupPartName`	`string GetBodygroupPartName(int group, int part)`	Get the bodygroup's name by group and part.
`GetBoneAngles`	`QAngle GetBoneAngles(int ID)`	Get the bone's angles as a QAngle, by ID. Warning:For performance, bone transforms are cached by the game. The cache is updated once per frame. Setting new sequences, cycles etc may cause this to access stale bone data. If this is a problem, then call `SetModelSimple` first, which will update the bone cache.
`GetBoneOrigin`	`Vector GetBoneOrigin(int ID)`	Get the bone's origin Vector by ID. Warning:See above.
`GetCycle`	`float GetCycle()`	Gets the model's current animation cycle rate.
`GetModelScale`	`float GetModelScale()`	Get the model's scale.
`GetPlaybackRate`	`float GetPlaybackRate()`	Get the current animation's playback rate.
`GetSequence`	`int GetSequence()`	Get the current-playing sequence's ID.
`GetSequenceActivityName`	`string GetSequenceActivityName(int ID)`	Get the activity name for a sequence by sequence ID.
`GetSequenceDuration`	`float GetSequenceDuration(int ID)`	Get a sequence duration in seconds by sequence ID.
`GetSequenceName`	`string GetSequenceName(int ID)`	Get a sequence name by sequence ID. Returns "Not Found!" if ID is -1, "Unknown" if the sequence doesn't exist or "No model!" if no model is assigned.
`GetSkin`	`int GetSkin()`	Gets the current skin index.
`IsSequenceFinished`	`bool IsSequenceFinished()`	Ask whether the main sequence is done playing.
`LookupActivity`	`int LookupActivity(string activity)`	Get the named activity index. Returns -1 if the activity does not exist.
`LookupAttachment`	`int LookupAttachment(string name)`	Get the named attachment index. Returns 0 if the attachment does not exist.
`LookupBone`	`int LookupBone(string bone)`	Get the named bone index. Returns -1 if the bone does not exist.
`LookupPoseParameter`	`int LookupPoseParameter(string name)`	Gets the pose parameter's index. Returns -1 if the pose parameter does not exist.
`LookupSequence`	`int LookupSequence(string name)`	Looks up a sequence by names of sequences or activities. Returns -1 if the sequence does not exist.
`ResetSequence`	`void ResetSequence(int ID)`	Reset a sequence by sequence ID. If the ID is different than the current sequence, switch to the new sequence.
`SetBodygroup`	`void SetBodygroup(int ID, int value)`	Set the bodygroup by ID.
`SetCycle`	`void SetCycle(float cycle)`	Sets the model's current animation cycle from 0 to 1. Note:This only works if the entity has `m_bClientSideAnimation` set to false. Some entities such as prop_dynamic have this true by default and therefore SetCycle will visually not do anything until that netprop is turned off.
`SetModelSimple`	`void SetModelSimple(string model_name)`	Set a model for this entity. Matches easier behaviour of the SetModel input, automatically precaches, maintains sequence/cycle if possible. Also clears the bone cache. Note:Does nothing on players. Use `SetCustomModel` in that case.
`SetModelScale`	`void SetModelScale(float scale, float change_duration)`	Changes a model's scale over time. Set the change duration to 0.0 to change the scale instantly.
`SetPlaybackRate`	`void SetPlaybackRate(float rate)`	Set the current animation's playback rate.
`SetPoseParameter`	`float SetPoseParameter(int ID, float value)`	Sets a pose parameter value. Returns the effective value after clamping or looping. Note:Does nothing on players. Pose parameters aren't networked on players. Bug:prop_dynamic will have visual glitches with server-sided pose parameters. Use point_posecontroller, or another entity like base_boss or funCBaseFlex. [todo tested in?]
`SetSequence`	`void SetSequence(int ID)`	Plays a sequence by sequence ID. Warning:This can cause animation stutters when transitioning between sequences, or sequences to not be set at all on some entities (such as obj_sentrygun). Using `ResetSequence` instead will prevent this. Only tested on base_boss. Note:Does nothing on players. Players use a different animation system.
`SetSkin`	`void SetSkin(int index)`	Sets the model's skin.
`StopAnimation`	`void StopAnimation()`	Stop the current animation (same as SetPlaybackRate 0.0)
`StudioFrameAdvance`	`void StudioFrameAdvance()`	Advance animation frame to some time in the future with an automatically calculated interval
`StudioFrameAdvanceManual`	`void StudioFrameAdvanceManual(float dt)`	Advance animation frame to some time in the future with a manual interval

CBaseCombatWeapon

Extends CBaseAnimating ↑

Script handle class for any weapon entities that can be part of a player's inventory.
Team Fortress 2's weapons leave Clip2 unused, so those functions can be ignored

Methods

Function	Signature	Description
`CanBeSelected`	`bool CanBeSelected()`	Can this weapon be selected
`Clip1`	`int Clip1()`	Current ammo in clip1
`Clip2`	`int Clip2()`	Current ammo in clip2
`GetDefaultClip1`	`int GetDefaultClip1()`	Default size of clip1
`GetDefaultClip2`	`int GetDefaultClip2()`	Default size of clip2
`GetMaxClip1`	`int GetMaxClip1()`	Max size of clip1
`GetMaxClip2`	`int GetMaxClip2()`	Max size of clip2
`GetName`	`string GetName()`	Gets the weapon's internal name (not the targetname!) Warning:This conflicts with CBaseEntity's `GetName` function. To get the targetname of the weapon, call it like this instead `CBaseEntity.GetName.call(weapon)`
`GetPosition`	`int GetPosition()`	Gets the weapon's current position
`GetPrimaryAmmoCount`	`int GetPrimaryAmmoCount()`	Current primary ammo count if no clip is used or to give a player if they pick up this weapon legacy style (not TF)
`GetPrimaryAmmoType`	`int GetPrimaryAmmoType()`	Returns the primary ammo type
`GetPrintName`	`string GetPrintName()`	Gets the weapon's print name
`GetSecondaryAmmoCount`	`int GetSecondaryAmmoCount()`	Current secondary ammo count if no clip is used or to give a player if they pick up this weapon legacy style (not TF)
`GetSecondaryAmmoType`	`int GetSecondaryAmmoType()`	Returns the secondary ammo type
`GetSlot`	`int GetSlot()`	Gets the weapon's current slot
`GetSubType`	`int GetSubType()`	Get the weapon subtype
`GetWeaponFlags`	`int GetWeaponFlags()`	Get the weapon flags
`GetWeight`	`int GetWeight()`	Get the weapon weighting/importance
`HasAnyAmmo`	`bool HasAnyAmmo()`	Do we have any ammo?
`HasPrimaryAmmo`	`bool HasPrimaryAmmo()`	Do we have any primary ammo?
`HasSecondaryAmmo`	`bool HasSecondaryAmmo()`	Do we have any secondary ammo?
`IsAllowedToSwitch`	`bool IsAllowedToSwitch()`	Are we allowed to switch to this weapon?
`IsMeleeWeapon`	`bool IsMeleeWeapon()`	Returns whether this is a melee weapon Note:`tf_weapon_buff_item` (entity for Soldier's banner items), are considered melee in the code.
`PrimaryAttack`	`void PrimaryAttack()`	Force a primary attack Tip:This allows arbitrarily firing weapons that do not actually belong to any player. This can be useful for creating entities that might not fully work on their own, for example rockets. Most weapons will work as long as the `m_hOwner` netprop on the weapon is set to an existing player. Weapons spawned manually might also need `SetClip(-1)`, and `m_flNextPrimaryAttack` (or `m_flSecondaryPrimaryAttack`) set to 0 before calling this function to always allow firing without delays. Warning:Hitscan and melee weapons require lag compensation information to be present, or the game will crash! Calling this from a player's think function or OnTakeDamage hook (whose source is a player's hitscan weapon) is sufficient. Alternatively, lag compensation can be temporarily disabled which allows calling this function from anywhere, with the side effect of poor hit registration for high latency players. This can be achieved by setting the `m_bLagCompensation` netprop ↓ on the player to to false, calling this function, and reverting it back to true. Warning:This will play the weapon's fire sound to everyone except the owner. If the sound is desired, the sound can be played to the owner exclusively via `EmitSoundEx`. If the sound is not desired, it can be stopped by calling `StopSound` after this function.
`SecondaryAttack`	`void SecondaryAttack()`	Force a secondary attack Warning:See above.
`SetClip1`	`void SetClip1(int amount)`	Set current ammo in clip1.
`SetClip2`	`void SetClip2(int amount)`	Set current ammo in clip2.

`UsesClipsForAmmo2`	`bool UsesClipsForAmmo2()`	Do we use clips for ammo 2?
`UsesPrimaryAmmo`	`bool UsesPrimaryAmmo()`	Do we use primary ammo?
`UsesSecondaryAmmo`	`bool UsesSecondaryAmmo()`	Do we use secondary ammo?
`VisibleInWeaponSelection`	`bool VisibleInWeaponSelection()`	Is this weapon visible in weapon selection

Alternatively, use the `rr_debugresponses 1` command with `developer 1` to find .vcds from in-game voicelines.

CBaseCombatCharacter

Extends CBaseFlex ↑

Combat entities with similar movement capabilities to a player.

Methods

Function	Signature	Description

`SnapEyeAngles`	`void SnapEyeAngles(QAngle angles)`	Snap the player's eye angles to this. Note:Do not use this if you are setting the angles temporarily and reverting it in the same frame (for example if firing projectiles at a specific angle). This will cause camera jitter in multiplayer. Instead, modify the `pl.v_angle` netprop and then revert that (which is what the game reads for eye angles internally). Example: local eye_angles = player.LocalEyeAngles() NetProps.SetPropVector(player, "pl.v_angle", angles + Vector()) NetProps.SetPropEntity(flaregun, "m_hOwner", player) NetProps.SetPropFloat(flaregun, "m_flNextPrimaryAttack", 0) flaregun.PrimaryAttack() NetProps.SetPropVector(player, "pl.v_angle", eye_angles + Vector())

`AddCustomAttribute`	`void AddCustomAttribute(string name, float value, float duration)`	Add a custom attribute to the player. Set duration to -1 for the attribute to be applied forever. Note:This does not work when applied in the `player_spawn` event, because custom attributes are cleared immediately after the event. As a workaround, it can be applied with a delay. See the example code.
`AddHudHideFlags`	`void AddHudHideFlags(int flags)`	Hides a hud element based on Constants.FHideHUD
`ApplyPunchImpulseX`	`bool ApplyPunchImpulseX(float impulse)`	Apply a view punch along the pitch angle. Used to flinch players when hit.

`ExtinguishPlayerBurning`	`void ExtinguishPlayerBurning()`
`FiringTalk`	`void FiringTalk()`	Makes eg. a heavy go AAAAAAAAAAaAaa like they are firing their minigun. Note:This only works in a few situations as it requires certain gameplay conditions to be true. An example of when this will work: when the player is invulnerable. Bug:Unfortunately does not work for Heavy's minigun due to the above quirk. [todo tested in?]
`ForceChangeTeam`	`void ForceChangeTeam(int team, bool full_team_switch)`	Force player to change their team. Setting the bool to true will not remove nemesis relationships or reset the player's class, as well as not slaying the player. Note:This will not work if a player is in a duel.

`SetNextRegenTime`	`void SetNextRegenTime(float time)`	Set next available resupply time.
`SetPlayerClass`	`void SetPlayerClass(int class)`	Sets the player class. Updates the player's visuals and model. Note:Does not force the class to be changed and can be buggy for server-side scripts. This can be resolved by calling `NetProps.SetPropInt(player, "m_Shared.m_iDesiredPlayerClass", classIndex)` after `SetPlayerClass` and before `ForceRegenerateAndRespawn`. This resolves issues like the player respawning as their "desired" class instead or loadout showing the desired class rather than what they are. Note:Does not regenerate class properties, such as health or weapons. This can be done by calling `ForceRegenerateAndRespawn` afterwards. Warning:If the player is not respawned, the hitbox set will be used from the old class! Calling `SetCustomModel` with a blank parameter is sufficient to update it.
`SetRageMeter`	`void SetRageMeter(float percent)`	Sets rage meter from 0 - 100.

`StunPlayer`	`void StunPlayer(float duration, float move_speed_reduction, int flags, handle attacker)`	Stuns the player for a specified duration. Move speed reduction is a fraction (0 = no reduction. 1 = total reduction, no movement). Flag combinations control the stun type and behavior, see the constants page.
`Taunt`	`void Taunt(int taunt_index, int taunt_concept)`	Performs a taunt if allowed. For taunt index, see Constants.FTaunts. For concepts, see MP_CONCEPT List. Concept is the "voiceline" index to use with the taunt. For `TAUNT_SHOW_ITEM` and `TAUNT_BASE_WEAPON` this is set automatically. `TAUNT_LONG` is not supported. Tip:TAUNT_MISC_ITEM with a concept of `MP_CONCEPT_TAUNT_LAUGH` will make the player laugh. Concept `MP_CONCEPT_TAUNT_REPLAY` will play the replay taunt.

Revved with a minigun Just fired with a sniper rifle Blowing the horn of a banner item Holding Half-Zatoichi and under 50 health Backstab stun from a Razorback -> Set `m_hActiveWeapon` on the player to null. Player has `TF_COND_CANNOT_SWITCH_FROM_MELEE` condition (from eating Buffalo Steak Sandvich) and is holding a melee -> Remove `TF_COND_CANNOT_SWITCH_FROM_MELEE` condition. Using the Thermal Thruster: // assuming "weapon" is the thermal thruster NetProps.SetPropEntity(player, "m_hActiveWeapon", null) if (player.InCond(Constants.ETFCond.TF_COND_ROCKETPACK)) { // needed to stop air sound SendGlobalGameEvent("rocketpack_landed", { userid = GetPlayerUserID(player) }) player.RemoveCond(Constants.ETFCond.TF_COND_ROCKETPACK) }

Note:There's more methods in input form. See base_boss page.

Convars

Game Instance: Convars

An interface to manipulate the convars on the server.

Note:Protected convars (e.g. rcon_password) cannot be accessed.

Methods

Function	Signature	Description
`GetBool`	`bool GetBool(string name)`	Returns the convar as a bool. May return null if no such convar.
`GetClientConvarValue`	`string GetClientConvarValue(string name, int entindex)`	Returns the convar value for the entindex as a string. Only works on client convars with the FCVAR_USERINFO flag. Tip:The list of available client convars can be printed in console using the `findflags USERINFO` command. Note:Notable client convars available: cl_autoreload : Whether the client wants autoreload after each shot cl_autorezoom : Whether the client wants auto scope-in after firing a sniper rifle cl_flipviewmodels : Whether the client has flipped viewmodels cl_language : The client's language setting cl_spec_mode : Currently observer mode, corresponds to the constants. fov_desired : The client's FOV hud_classautokill : If the client wants to suicide after choosing a new class hud_combattext : Whether damage numbers are enabled name : The client's name closecaption : Whether the client has closed captions enabled.
`GetInt`	`int GetInt(string name)`	Returns the convar as an int. May return null if no such convar.
`GetStr`	`string GetStr(string name)`	Returns the convar as a string. May return null if no such convar. Returns `hunter2` if a protected convar is accessed.

Please be nice with this and use it for compatibility if you need check support and NOT to force server owners to allow hostname to be set... or else this will simply lie and return true in future. ;-) You have been warned!
`SetValue`	`void SetValue(string name, any value)`	Sets the value of the convar. The convar must be in cfg/vscript_convar_allowlist.txt to be set. Convars marked as cheat-only can be set even if sv_cheats is off. Convars marked as dev-only (i.e. not visible in console) can also be set. Supported types are bool, int, float, string. The original value of the convar is saved and is reset on map change, in other words convar changes will not persist across maps. Warning:For changes intended to persist for the whole map, set these at the start of each round instead of only once. Otherwise, custom server configs may load after the initial script and not use the correct settings.

CEntities

Game Instance: Entities

An interface to find and iterate over the script handles for the entities in play. To iterate over a set of entities, pass null to the previous parameter in the appropriate method to start an iteration. A reference to a previously-found entity can be used instead to continue a search.

The following are two equivalent examples and iterate over all weapons on the map:

local ent = null
while ( ent = Entities.FindByClassname(ent, "tf_weapon_*") )
{
  // ...
}

for (local ent; ent = Entities.FindByName(ent, "tf_weapon_*"); )
{
  // ...
}

Note:

The variable name ent is arbitrary.
Indeed, we mean "=" and not "==" in the loop conditions! The loops end if ent becomes null, which happens when no matching entities have an entity index higher to the one in previous parameter.
Semicolons are optional, except in the header of the for statement.
The string parameters of the FindBy... functions support the wildcard star *. In the above example, FindByClassname only returns either a handle of an entity whose classname begins with "tf_weapon_" or it returns null.

Methods

Function	Signature	Description
`CreateByClassname`	`handle CreateByClassname(string classname)`	Creates an entity by classname. Tip:Example usage: local prop = Entities.CreateByClassname("prop_dynamic")

There might be entities that have a different classname than the one they are created with. For example you can spawn a "prop_dynamic" then change its classname to "my_prop", and it will retain the functionality of its code class while also not showing up when searching for "prop_dynamic".
`FindByClassnameNearest`	`handle FindByClassnameNearest(string classname, Vector center, float radius)`	Find entities by classname nearest to a point within a radius.

CNetPropManager

Game Instance: NetProps

Allows reading and updating the network properties and data-maps of an entity. A brief explanation: all entities in the game have 2 types of internal properties: networked and saved (called "data" by the game). Networked properties are transmitted to the client, while data properties are a leftover from singleplayer games, which are properties that get saved to a save file (that can be re-loaded later). Some properties may exist in both lists, or one list but not the other and vice versa, so it's best to check both lists. Entities follow an inheritance tree, and they inherit the properties of their parent(s). For organization/optimization purposes, properties also tend to be nested inside "tables".

Netprops nested in a table can be accessed using dot notation similar to a Squirrel table. Example: to access the netprop m_bJumping on a player, you would specify m_Shared.m_bJumping.

Note:Sometimes the table structure is figured out automatically and doesn't need to be specified explicitly. The easiest way to check is to use HasProp to see if its correct. For example, LocalWeaponData and LocalActiveWeaponData don't need to be specified. But on the contrary, m_Collision, m_Shared and m_AttributeManager (+ m_Item) must be explicitly specified.

Tip:Resources for finding netprops and datamaps of entities:

Interactive viewer of netprops: https://jackz.me/netprops/tf2
Formatted list of netprops and datamaps: https://sigwiki.potato.tf/index.php/Entity_Properties
Raw list of netprops and datamaps: https://www.invalidvertex.com/tf2dump.php
Better raw list of datamaps that includes type information: https://cdn.discordapp.com/attachments/1039243316920844428/1095872595049599056/dump_datamaps.txt

Warning:Each netprop has a set size in bits, exceeding the size may desync the clients from the server causing unpredictable behavior.

Note:Netprops containing the substring EntityQuality or AccountID are banned and cannot be set nor fetched, to prevent spoofing economy items as legitimate.

Tip:Run the code below to fold netprop functions for easier and more efficient usage. E.g. NetProps.GetPropInt would simply become GetPropInt.

foreach (k, v in ::NetProps.getclass())
    if (k != "IsValid")
        getroottable()[k] <- ::NetProps[k].bindenv(::NetProps)

CScriptKeyValues

Script handle representation of a model's $keyvalues block. All sub-keys are instances of the same class.

Methods

Function	Signature	Description
`constructor`
`FindKey`	`CScriptKeyValues FindKey(string key)`	Find a sub key by the key name.

`SpawnEntityAtNamedEntityOrigin`	`void SpawnEntityAtNamedEntityOrigin(string targetname)`	Create an entity at the location of a named entity. If multiple entities have the same name, only the one with the lowest entity index will be targeted.

CPointTemplate

Extends CBaseEntity ↑

Script handle class for point_template.

Hooks

table PreSpawnInstance(string entityClass, string entityName): If this is defined, it will be called right before the entity is created, and any keyvalues returned will be assigned to the entity.

function PreSpawnInstance( entityClass, entityName )
{
	local keyvalues =
	{ 
   		rendercolor = "0 255 0",
   		targetname = "mySpawnedEntity"
	}

	return keyvalues
}

void PostSpawn(table entities): Called after the entities are spawned. A table with the handles of the spawned entities indexed by name is passed to the function. Could use this to connect outputs or do whatever needs to be done after the entity was created.

Note:PostSpawn() will not be called unless the PreSpawnInstance() function is also defined in the script.

function PostSpawn( entities )
{
	foreach( targetname, handle in entities )
	{
		printl( targetname + ": " + handle )
	}
}

Example

Spawned entities can be accessed synchronously in script by using an entity maker. The following generalised example creates a global SpawnMyEntity() function which spawns and returns the templated entity. It can be modified to support multiple templated entities.

m_hSpawnedEntity <- null
m_KeyValues <- null

m_hSpawner <- Entities.CreateByClassname( "env_entity_maker" )
m_hSpawner.__KeyValueFromString( "EntityTemplate", self.GetName() )

function PreSpawnInstance( classname, targetname )
{
	return m_KeyValues
}

function PostSpawn( entities )
{
	foreach ( targetname, entity in entities )
	{
		m_hSpawnedEntity = entity
		break
	}
}

::SpawnMyEntity <- function( keyvalues = null )
{
	m_KeyValues = keyvalues
	m_hSpawner.SpawnEntity()
	return m_hSpawnedEntity
}.bindenv(this)

Spawn templated entities from any script.

local ent = SpawnMyEntity( {
	rendercolor = Vector( RandomInt(0, 255), RandomInt(0, 255), RandomInt(0, 255) )
} )

printl( ent )

CFuncTrackTrain

Extends CBaseEntity ↑

Script handle class for func_tracktrain.

CPointScriptTemplate

Extends CBaseEntity ↑

Script handle class for point_script_template.

Methods

Function	Signature	Description

`SetGroupSpawnTables`	`void SetGroupSpawnTables(table group, table spawn)`	Unused. This only stores a reference to the two tables which is removed when the `point_script_template` is deleted.

Note:To spawn every added template, fire the ForceSpawn input onto the point_script_template with AcceptInput.

Hooks

PreSpawnInstance hook from point_template is not available.

void PostSpawn(table entities): Called after the entities are spawned. A table with the handles of the spawned entities indexed by name is passed to the function.

Bug:As the PreSpawnInstance hook is not implemented, this callback is never fired. This can be fixed however by defining an entity table named __EntityMakerResult in the entity's scope. [todo tested in?]

Tip:Due to tables requiring unique keys, templated entities that have no targetname or have conflicting ones will not be present in the table. A workaround is to intercept the __EntityMakerResult table and add every entity to an array instead, as shown in the following example:

local template = SpawnEntityFromTable("point_script_template", {})
template.SetGroupSpawnTables({})

local scope = template.GetScriptScope()
scope.Entities <- []
scope.__EntityMakerResult <- {entities = scope.Entities}.setdelegate({_newslot = function(_, value) {entities.append(value)}})
scope.PostSpawn <- function(named_entities)
{
	__DumpScope(0, Entities)
}

template.AddTemplate("prop_dynamic",
{
	model = "models/player/heavy.mdl",
	origin = Vector(247, -281, -123)
})

template.AddTemplate("prop_dynamic",
{
	model = "models/player/spy.mdl",
	origin = Vector(247, -381, -123)
})

template.AcceptInput("ForceSpawn", "", null, null)

CCallChainer

CCallChainer objects collect all functions with a matching prefix in a given scope, then inserts it all into the chains table with the prefix removed. All collected unprefixed functions can then be called in a chain using the class's Call() method, given the method's event argument matches the functions' name.

Whenever a CCallChainer object is created, a function named Dispatch followed by its given prefix will also be created, which the class binds the environment of its Call() method to.

Todo: Descriptions of the operations are lacking details.

Operation	Return Type	Description
`Quaternion + Quaternion`	`Quaternion`	Sum of the two Quaternions.
`Quaternion - Quaternion`	`Quaternion`	Subtraction of the two Quaternions.
`Quaternion * integer`	`Quaternion`	Quaternion multiplied by a number.
`Quaternion * float`	`Quaternion`	Quaternion multiplied by a number.

Globals

Function	Signature	Description
`AddThinkToEnt`	`void AddThinkToEnt(handle entity, string FuncName)`	Sets a function in the entity's script to rerun by itself constantly. Pass null as the function name to remove a think function. The default think interval is 0.1s, unless overridden by returning a different time interval in seconds in the think function. TF2 runs at 66 ticks per second, so the lowest possible interval is 0.015 seconds. Tip:Return -1 to think every tick. Do not return 0 or 0.015, this will give inconsistent intervals. Confirm:This issue has only been observed on players Note:If trying to clear a think function while inside a think function, `AddThinkToEnt` will not work as the think function is restored on the entity after it's finished. `NetProps.SetPropString(self, "m_iszScriptThinkFunction", "")` must be used to remove the think function. Warning:This can apply to events if they are chained from a think function, for example killing a player with `TakeDamage` and then trying to clear the think function in `player_death` event. The think function will not be cleared unless the line above is also added. Note:Some entities are sensitive to when this think function executes within a frame. A notable example is modifying the tf_player_manager entity. The think function must be applied to the manager entity for netprop changes to work correctly, and not any other entity, otherwise modifying its properties will be inconsistent. Bug:The think function name stored in the entity is not reset if null is passed as the function name. However this is harmless, and it will only show a warning in console. [todo tested in?]
`AddToScriptHelp`	`AddToScriptHelp()`
`AllowThirdPersonCamera`	`bool AllowThirdPersonCamera()`
`ArePlayersInHell`	`bool ArePlayersInHell()`
`Assert`	`void Assert(bool value, string optional message)`	Test value and if not true, throws exception, optionally with message.
`ClearGameEventCallbacks`	`void ClearGameEventCallbacks()`	Empties the tables of game event callback functions. Deprecated:Do NOT use this! It removes all events, including those from other scripts, and is a common source of script conflicts. Instead, update your event code to use a namespace (define and contain your callback functions inside of a table), which will clean up automatically when this table is removed without interfering with other scripts. Refer to the examples page for guidance on how to set an automatic system for this.
`CreateProp`	`handle CreateProp(string classname, Vector origin, string model_name, int activity)`	Create a prop
`CreateSceneEntity`	`handle CreateSceneEntity(string scene)`	Create a scene entity to play the specified scene.
`developer`	`int developer()`	The current level of the `developer` console variable.
`DispatchParticleEffect`	`void DispatchParticleEffect(string name, Vector origin, Vector direction)`	Dispatches a one-off particle system. To pass angles into this, use the `.Forward()` method on a QAngle. Note:For more control over particles such as parenting them to entities, see the examples page for alternative methods. Warning:This does not precache custom particles. As a result, custom particles may show as a burst of red Xs instead on dedicated servers. To precache a particle, use the following function: function PrecacheParticle(name) { PrecacheEntityFromTable({ classname = "info_particle_system", effect_name = name }) }
`Document`	`void Document(unknown symbolOrTable, unknown itemIfSymbol = null, string descriptionIfSymbol = null)`
`DoEntFire`	`void DoEntFire(string target, string action, string value, float delay, handle activator, handle caller)`	Generate an entity I/O event. The caller and activator argument takes a CBaseEntity script handle, and entities assigned can receive inputs with target set to !self, or !activator / !caller. Negative delays are clamped to 0. Note:Does not work if the target string is `point_servercommand`.
`DoIncludeScript`	`bool DoIncludeScript(string file, handle/table scope)`	Execute a script and put all its content for the argument passed to the`scope`parameter. The file must have the `.nut` extension. Warning:Do not put uppercase letters in the path, doing so will cause Linux to fail loading the script from loose directories.
`IncludeScript`	`bool IncludeScript(string file, handle scope = null)`	Wrapper for DoIncludeScript.
`EmitAmbientSoundOn`	`void EmitAmbientSoundOn(string soundName, float volume, int soundlevel, int pitch, handle entity)`	Play named sound on an entity using configurations similar to ambient_generic. Soundlevel is in decibels, see this page for real world equivalents. Tip:Sounds may be hard to hear even at full volume. Naming custom sounds according to the soundmixer can be used to make them naturally louder. Tip:To convert radius in Hammer units to decibels (similar to ambient_generic), use the following formula: local soundlevel = (40 + (20 * log10(radius / 36.0))).tointeger()
`StopAmbientSoundOn`	`void StopAmbientSoundOn(string soundName, handle entity)`	Stop named sound on an entity using configurations similar to ambient_generic.
`EmitSoundEx`	`void EmitSoundEx(handle table)`	Play a sound. Takes in a script table of params: `sound_name`, `channel`, `volume`, `sound_level`, `flags`, `pitch`, `special_dsp`, `origin`, `delay`, `sound_time`, `entity`, `speaker_entity`, `filter_type`, `filter_param`. All parameters are optional except sound_name. See the main page for more details.
`EmitSoundOn`	`void EmitSoundOn(string soundScript, handle entity)`	Play named sound on given entity. The sound must be precached first for it to play (using `PrecacheSound` or `PrecacheScriptSound`). Warning:Looping sounds will not stop on the entity when it's destroyed and will persist forever! To workaround this, run `StopSound` in the `OnDestroy` callback.
`StopSoundOn`	`void StopSoundOn(string soundScript, handle entity)`	Stop named sound on an entity.
`EmitSoundOnClient`	`void EmitSoundOnClient(string soundScript, handle player)`	Play named sound only on the client for the specified player. The sound must be precached first for it to play (`PrecacheScriptSound`). Note:This only supports soundscripts.
`EntFire`	`void EntFire(string target, string action, string value = null, float delay = 0, handle activator = null)`	Wrapper for DoEntFire() that sets`activator` to null, but has no`caller`param. Negative delays are clamped to 0. Note:Does not work if the target string is `point_servercommand`.
`EntFireByHandle`	`void EntFireByHandle(handle entity, string action, string value, float delay, handle activator, handle caller)`	Generate an entity I/O event. First parameter is an entity instance. Negative delays are clamped to 0. Note:With a 0 delay, this will be processed at the end of the frame rather than instantly. If you need an instant, synchronous I/O event then use `AcceptInput` instead.
`EntIndexToHScript`	`handle EntIndexToHScript(int entIndex)`	Turn an entity index integer to an HScript representing that entity's script instance.
`FileToString`	`string FileToString(string file)`	Reads a string from file located in the game's scriptdata folder. Returns the string from the file, null if no file or file is greater than 16384 bytes. Note:Files packed inside the BSP cannot be read. Note:This opens files in text mode, therefore binary files will not be parsed correctly.
`FindCircularReference`	`FindCircularReference()`
`FindCircularReferences`	`FindCircularReferences()`
`FireGameEvent`	`bool FireGameEvent(string name, handle table)`	Fire a game event to a listening callback function in script. Parameters are passed in a squirrel table. Note:The name might be misleading. This does not fire an event that the game will pick up, the function that sends a real game event is named `SendGlobalGameEvent`.
`FireScriptHook`	`bool FireScriptHook(string name, handle table)`	Fire a script hook to a listening callback function in script. Parameters are passed in a squirrel table.
`FireScriptEvent`	`void FireScriptEvent(string event, table params)`	Wrapper for `__RunEventCallbacks()`
`ForceEnableUpgrades`	`void ForceEnableUpgrades(int state)`	Whether to force on MvM-styled upgrades on/off. 0 -> default, 1 -> force off, 2 -> force on
`ForceEscortPushLogic`	`void ForceEscortPushLogic(int state)`	Forces payload pushing logic. 0 -> default, 1 -> force off, 2 -> force on
`FlagsMayBeCapped`	`bool FlagsMayBeCapped()`	May a flag be captured?

`GetClassLimit`	`int GetClassLimit(int class)`	Get class limit for class. See Constants.ETFClass.
`GetDeveloperLevel`	`int GetDeveloperLevel()`	Gets the level of 'developer'
`GetFrameCount`	`int GetFrameCount()`	Returns the engines current frame count. The counter does not reset between map changes. This is NOT the tick count. Tip:To get the current tick count, read the `m_nSimulationTick` netprop from any player or moving entity.
`GetFriction`	`float GetFriction(handle player)`	Returns the Friction on a player entity, meaningless if not a player
`GetFunctionSignature`	`string GetFunctionSignature(function func, string prefix)`
`GetGravityMultiplier`	`float GetGravityMultiplier()`
`GetListenServerHost`	`handle GetListenServerHost()`	Get the local player on a listen server. Returns null on dedicated servers. Note:This depends on the player entity, and therefore this might return null on a listen server if the player doesn't exist yet during map load. Use `IsDedicatedServer` instead to check if the server is a listen or dedicated server, as it checks it in a different way. Tip:Alternatively, use `PlayerInstanceFromIndex(1)` to fetch the first player on the server. For convenience sake (e.g. for script compatibility), you can map this to that function using the following: ::GetListenServerHost <- @() PlayerInstanceFromIndex(1)
`GetMannVsMachineAlarmStatus`	`bool GetMannVsMachineAlarmStatus()`
`GetMapName`	`string GetMapName()`	Get the name of the map without extension, e.g. `ctf_2fort`. For workshop maps, this will be in the format `workshop/[name].ugc[id]`.
`GetModelIndex`	`int GetModelIndex(string filename)`	Returns the index of the named model.
`GetOvertimeAllowedForCTF`	`bool GetOvertimeAllowedForCTF()`
`GetPhysAngularVelocity`	`Vector GetPhysAngularVelocity(handle entity)`	Returns the Angular velocity of the entity. Deprecated, use the `GetPhysAngularVelocity` method on the entity instead.
`GetPhysVelocity`	`Vector GetPhysVelocity(handle entity)`	Returns the velocity of the entity. Deprecated, use the `GetPhysVelocity` method on the entity instead.
`GetPlayerFromUserID`	`handle GetPlayerFromUserID(int userid)`	Given a user id, return the entity, or null. Note:The 'fake' SourceTV player will always be returned as null. If you need to actually retrieve the SourceTV player, use `EntIndexToHScript`. Tip:For the opposite, getting the user id from an entity, see the examples page.
`GetRoundState`	`int GetRoundState()`	Get current round state. See Constants.ERoundState.
`GetSoundDuration`	`float GetSoundDuration(string soundname, string actormodelname)`	Returns float duration of the sound. Actor model name is optional and can be left null. Todo: Actor model name is likely a leftover from Half-Life 2 Warning:Does not work on dedicated servers as they do not have audio libraries built-in to load sounds.
`GetStopWatchState`	`int GetStopWatchState()`	Get the current stopwatch state. See Constants.EStopwatchState.
`GetWinningTeam`	`int GetWinningTeam()`	Who won!
`HaveStopWatchWinner`	`bool HaveStopWatchWinner()`

`IsWeakref`	`bool IsWeakref()`
`LocalTime`	`void LocalTime(table out)`	Fills out a table with the local time (second, minute, hour, day, month, year, dayofweek, dayofyear, daylightsavings). This mirrors the `tm` structure in C++, see the reference page for more information.
`MakeNamespace`	`MakeNamespace()`
`MapHasMatchSummaryStage`	`bool MapHasMatchSummaryStage()`
`MatchmakingShouldUseStopwatchMode`	`bool MatchmakingShouldUseStopwatchMode()`
`MaxClients`	`float MaxClients()`	Get the current number of max clients set by the maxplayers command. Bug:The return value is mistakenly defined as a float. It is best to use `.tointeger()` after calling this. [todo tested in?]
`PickupObject`	`void PickupObject(handle player, handle entity)`	Object from world is put into the "Held" slot of the player. Warning: it will smoothly interpolate from where it is to the players hand - which is a bit goofy if it is on other side of level. Note:Does nothing in Team Fortress 2 as the code is not implemented.
`PlayerInstanceFromIndex`	`CBasePlayer PlayerInstanceFromIndex(int index)`	Get a script handle of a player using the player index. Note:The 'fake' SourceTV player will always be returned as null. If you need to actually retrieve the SourceTV player, use `EntIndexToHScript`.
`PlayerReadyStatus_ArePlayersOnTeamReady`	`bool PlayerReadyStatus_ArePlayersOnTeamReady(int team)`
`PlayerReadyStatus_HaveMinPlayersToEnable`	`bool PlayerReadyStatus_HaveMinPlayersToEnable()`
`PlayerReadyStatus_ResetState`	`void PlayerReadyStatus_ResetState()`
`PlayersAreOnMatchSummaryStage`	`bool PlayersAreOnMatchSummaryStage()`
`PointsMayBeCaptured`	`bool PointsMayBeCaptured()`	Are points able to be captured?
`PrecacheEntityFromTable`	`bool PrecacheEntityFromTable(table keyvalues)`	Precache an entity from KeyValues in a table. Internally this function creates the entity, fire `DispatchSpawn` and removes it instantly. Returns false if the table has no classname key, if the value of classname is null or empty, or if the entity failed to be created. Tip:Can be used to precache gibs for a model on any entity by using tf_generic_bomb. Example: PrecacheEntityFromTable({ classname = "tf_generic_bomb", model = MODEL_NAME })
`PrecacheModel`	`int PrecacheModel(string filename)`	Precache a model (`.mdl`) or sprite (`.vmt`) and return model index. The extension must be specified. Returns -1 if null or empty filename is passed in. Missing models/sprites will still return a new index. Note:Does not precache gibs. See `PrecacheEntityFromTable` instead.
`PrecacheScriptSound`	`bool PrecacheScriptSound(string soundName)`	Precache a soundscript. Returns false if soundscript is missing, or if a null or empty sound name is passed in.
`PrecacheSound`	`bool PrecacheSound(string soundName)`	Precache a raw sound. Returns false if a null or empty sound name is passed in.
`PrintHelp`	`void PrintHelp()`	Equivalent to running `script_help` command.
`RandomFloat`	`float RandomFloat(float min, float max)`	Generate a random floating-point number within a range, inclusive.
`RandomInt`	`int RandomInt(int min, int max)`	Generate a random integer within a range, inclusive.
`RegisterFunctionDocumentation`	`void RegisterFunctionDocumentation(unknown func, string name, string signature, string description)`
`RegisterScriptGameEventListener`	`void RegisterScriptGameEventListener(string eventName)`	Register as a listener for a game event from script. It's what `__CollectGameEventCallbacks()` uses to register event callbacks to the C++ code. Note:This cannot be used to register non-existent game events.
`RegisterScriptHookListener`	`void RegisterScriptHookListener(string name)`	Register as a listener for a script hook from script.
`RetrieveNativeSignature`	`string RetrieveNativeSignature(function func)`
`RotateOrientation`	`QAngle RotateOrientation(QAngle, QAngle)`	Rotate a QAngle by another QAngle.
`RotatePosition`	`Vector RotatePosition(Vector origin, QAngle rotation, Vector input)`	Rotate the input Vector around an origin. Bug:This is not calculated correctly and the rotation will always be relative to (0, 0, 0). As a workaround, subtract the origin from the input, call this function and then add the origin back which will perform the expected result. [todo tested in?]
`ScreenFade`	`void ScreenFade(handle player, int red, int green, int blue, int alpha, float fadeTime, float fadeHold, int flags)`	Start a customisable screenfade. If no player is specified, the fade will apply to all players. For a list of flags, see FFADE constants.
`ScreenShake`	`void ScreenShake(Vector vecCenter, float flAmplitude, float flFrequency, float flDuration, float flRadius, int eCommand, bool bAirShake)`	Start a customisable screenshake. Set eCommand to 0 to start a shake, or 1 to stop an existing shake.
`ScriptHooksEnabled`	`bool ScriptHooksEnabled()`	Returns whether script hooks are currently enabled.
`SendGlobalGameEvent`	`bool SendGlobalGameEvent(string event_name, handle params)`	Sends a real game event to everything. Parameters are passed in a squirrel table. Warning:Certain events that are usually clientside only will not work when fired by this function, with an error complaining that "no listeners are registered for this event". However, defining an empty event listener will make it work. Warning:Events that upload statistics to Steam servers such as `player_escort_score` can take as long as 1 millisecond to execute! This can be prevented by temporarily giving the player the `FL_FAKECLIENT` flag and reverting it afterwards (however be careful not to revert it on actual bots!). Example: local is_bot = player.IsFakeClient() if (!is_bot) player.AddFlag(Constants.FPlayer.FL_FAKECLIENT) SendGlobalGameEvent("player_escort_score", { player = player.entindex(), points = 1 }) if (!is_bot) player.RemoveFlag(Constants.FPlayer.FL_FAKECLIENT)
`SendToConsole`	`void SendToConsole(string command)`	Issues a command to the local client, as if they typed in the command in their console. Does nothing on dedicated servers.
`SendToServerConsole`	`void SendToServerConsole(string command)`	Issues a command to the server, as if typed in the console. Note:This obeys the behavior of the `sv_allow_point_servercommand` convar. By default, this command will do nothing unless the server has this command to set to "always"
`SendToConsoleServer`	`void SendToConsoleServer(string command)`	Copy of SendToServerConsole with another name for compat.
`SetFakeClientConVarValue`	`void SetFakeClientConVarValue(handle bot, string cvar, string value)`	Sets a USERINFO client ConVar for a fakeclient. Tip:This can be used to change the name of a bot by using the `name` cvar.
`SetGravityMultiplier`	`void SetGravityMultiplier(float multiplier)`
`SetMannVsMachineAlarmStatus`	`void SetMannVsMachineAlarmStatus(bool status)`
`SetOvertimeAllowedForCTF`	`void SetOvertimeAllowedForCTF(bool state)`
`SetPlayersInHell`	`void SetPlayersInHell(bool state)`
`SetSkyboxTexture`	`void SetSkyboxTexture(string texture)`	Sets the current skybox texture. The path is relative to "materials/skybox/". Only the main name of a skybox texture is needed, for example "sky_gravel_01".
`SetUsingSpells`	`void SetUsingSpells(bool state)`
`SpawnEntityFromTable`	`handle SpawnEntityFromTable(string name, handle keyvalues)`	Spawn entity from KeyValues in table - 'name' is entity name, rest are KeyValues for spawn. Note:Multiple keys of the same name can be specified by appending the key with an incremental #x suffix. Note:`parentname` is not resolved and therefore will not work. Instead, fire `AcceptInput` after spawning (with `SetParent !activator` parameters), or use `SpawnEntityGroupFromTable`. Tip:If spawning multiple entities at once, use `SpawnEntityGroupFromTable` as it will be more efficient. Example: SpawnEntityFromTable("logic_timer", { targetname = "cool" RefireTime = 60 "OnTimer#1" : "entity,Trigger,,0,-1" "OnTimer#2" : "somethingelse,Disable,,0,-1" }) Warning:If using commas inside the parameter field of a output key, it will not be parsed correctly as the comma will be treated as delimiter. To fix this, an special delimiter also supported by the game can be used named 'ESC'. This cannot be typed on a keyboard normally, and must be copied from another source. The easiest way is to open this link, and copy + paste the character in a supporting editor such as Notepad++. Example (the character will not display correctly on this page): "OnTrigger#5": "res,RunScriptCode,NetProps.SetPropString(self, `m_iszMvMPopfileName`, `test`),0,-1" would instead be changed to "OnTrigger#5": "res�RunScriptCode�NetProps.SetPropString(self, `m_iszMvMPopfileName`, `test`)�0�-1" Note:If using a complex model, usually custom models, it might cause stutters to the server when spawning it. To work around this issue instead spawn it with `CreateByClassname` and set its netprops manually, and don't forget to make sure the model is precached properly too.
`SpawnEntityGroupFromTable`	`bool SpawnEntityGroupFromTable(handle groups)`	Hierarchically spawn an entity group from a set of spawn tables. This computes a spawn order for entities so that parenting is resolved correctly. The table for this must take the following format. `group` can be any name, as long as it's unique. Each group can only contain one entity. (The table is formatted like this as otherwise it wouldn't be possible to spawn multiple entities of the same classname). The function always returns true, even if entity spawning fails. { <group> = { <classname> = { // key - values } }, // ... } Example usage: SpawnEntityGroupFromTable( { a = { info_particle_system = { origin = GetListenServerHost().GetOrigin(), parentname = "mytarget", effect_name = "soldierbuff_blue_soldier", start_active = true } }, b = { info_particle_system = { origin = GetListenServerHost().GetOrigin(), parentname = "mytarget", effect_name = "soldierbuff_red_soldier", start_active = true } }, }) Note:You will need to hijack an unused string netprop and set the bounding box data for brush entities there, then run a script on the entity to parse it. Example: Make a script file named "make_brush.nut" that contains the following: function OnPostSpawn() { local buf = split(NetProps.GetPropString(self, "m_iszResponseContext"), " ") self.SetSize(Vector(buf[0], buf[1], buf[2]), Vector(buf[3], buf[4], buf[5])) self.SetSolid(2) } Now you can set the min/max bounding box values for a brush ent directly in the ent key/values like so: SpawnEntityGroupFromTable({ [0] = { func_rotating = { message = "hl1/ambience/labdrone2.wav", responsecontext = "-1 -1 -1 1 1 1", vscripts = "make_brush", volume = 8, targetname = "crystal_spin", spawnflags = 65, solidbsp = 0, rendermode = 10, rendercolor = "255 255 255", renderamt = 255, maxspeed = 48, fanfriction = 20, angles = QAngle(), origin = Vector(), } }, [1] = { trigger_multiple = { targetname = "trigger1", responsecontext = "-250 -250 -250 250 250 250", vscripts = "make_brush", parentname = "crystal_spin", spawnflags = 1, "OnStartTouchAll#1": "!activator�RunScriptCode�ClientPrint(self, 3, `I am in trigger1`)�0�-1", } }, [2] = { prop_dynamic = { targetname = "crystal", solid = 6, renderfx = 15, rendercolor = "255 255 255", renderamt = 255, physdamagescale = 1.0, parentname = "crystal_spin", modelscale = 1.3, model = "models/props_moonbase/moon_gravel_crystal_blue.mdl", MinAnimTime = 5, MaxAnimTime = 10, fadescale = 1.0, fademindist = -1.0, origin = Vector(), angles = QAngle(45, 0, 0) } }, }) Tip:If a list of entity handles created from this function is needed, there is two workarounds: 1 - Assign a `vscripts` file that appends `this` to a global array. 2 - Use a `point_script_template`, see the spawn hook example ↑.
`StringToFile`	`void StringToFile(string file, string string)`	Stores a string as a file, located in the game's scriptdata folder. Warning:Since this writes to the disk, the performance will vary depending on the hardware (i.e. HDD or SSD). This function should only be called at checkpoints such as round restart or before level change, and not during gameplay to prevent hitches. Warning:This writes files in text mode, therefore binary files will not be written correctly. As another consequence, if writing multi-line strings directly, this may cause issues due to Window's encoding new lines as \r\n, but Mac/Linux encodes as \n. This can be fixed by setting EOL (end-of-line) encoding to Unix or CR in your text editor. Bug:A single NULL byte will always be appended to the end of the file [todo tested in?]
`Time`	`float Time()`	Get the current time since map load in seconds. The time resets on map change.
`TraceLine`	`float TraceLine(Vector start, Vector end, handle ignore)`	Trace a ray. Return fraction along line that hits world or models. Optionally, ignore the specified entity. Tip:Specify the same start and end point to check whether a point is inside solid geometry/out of bounds.
`TraceLineEx`	`bool TraceLineEx(table traceTable)`	Extended version of `TraceLine`. See the main page for more details.
`TraceLinePlayersIncluded`	`float TraceLinePlayersIncluded(Vector, Vector, handle)`	Different version of `TraceLine` that also hits players and NPCs.
`TraceHull`	`bool TraceHull(table traceTable)`	Trace a box (AABB). See the main page for more details.
`UniqueString`	`string UniqueString(string suffix = "")`	Generate a string guaranteed to be unique across the life of the script VM, with an optional suffix. Useful for adding data to tables when not sure what keys are already in use in that table. The format of the string is `_%x%llx_%s`, with arguments as follows: random number between 0 and 4095, an incrementing 64-bit counter, and suffix.
`DoUniqueString`	`string DoUniqueString(string suffix)`	Internal function called by `UniqueString`
`UsePlayerReadyStatusMode`	`bool UsePlayerReadyStatusMode()`
`VSquirrel_OnCreateScope`	`table VSquirrel_OnCreateScope(any value, table scope)`	Creates a new scope with the name of value in the submitted table (includes unique params).
`VSquirrel_OnReleaseScope`	`void VSquirrel_OnReleaseScope(table createdScope)`	Removes a scope created via VSquirrel_OnCreateScope.

`__CollectGameEventCallbacks`	`void __CollectGameEventCallbacks(table scope)`	Wrapper that registers callbacks for both OnGameEvent_x ↑ and `OnScriptEvent_` functions. Done using the `__CollectEventCallbacks` function.
`__ReplaceClosures`	`void __ReplaceClosures(script, scope)`
`__RunEventCallbacks`	`void __RunEventCallbacks(event, params, prefix, globalTableName, bWarnIfMissing)`	Call all functions in the callback array for the given game event
`__RunGameEventCallbacks`	`void __RunGameEventCallbacks(event, params)`	Wrapper for `__RunEventCallbacks()`
`__RunScriptHookCallbacks`	`void __RunScriptHookCallbacks(event, param)`

Printing and Drawing

Functions for printing out messages or drawing elements in the world, mostly for debugging reasons.

Warning:Any function with the Debug prefix requires the cvar developer be enabled and the game unpaused.
They also do not appear in multiplayer, only on a local server.

Function Signature Description

\x07 - custom color in hexadecimal RRGGBB format. Example: \x07FF3F3F
\x08 - custom color in hexadecimal RRGGBBAA format (i.e. with transparency). Example: \x08FF3F3FCC

Chat messages can contain multiple of these codes. If using color sequences, there MUST be a color sequence at the beginning of the string, or color codes won't work!.

Warning:

Will not accept these escape sequences. As a result, you cannot print colored text with a simple RunScriptCode input.

Workaround:See the VScript Examples page for a workaround that replaces a normal character with \x07 at run-time

Tip:Standard chat colors:

Default: FBECCB
RED: FF3F3F
BLUE: 99CCFF
Unassigned/spectator: CCCCCC

__DumpScope

void __DumpScope(int indentation, table scope)

Dumps a scope's contents and expands all tables and arrays; this is what the ent_script_dump command uses.

Tip:You can use this to print tables/arrays.

Example
Using this code: local testTable = { integer = 20, string = "hello", array = [1, 2, 3] } printl("{") __DumpScope(1, testTable) printl("}") Will print the following in console: { string = "hello" array(ARRAY) [ 0 = 1 1 = 2 2 = 3 ] integer = 20 }

DumpObject void DumpObject(handle object) Dumps information about a class or instance.

Msg void Msg(string message) Prints message to console without any line feed after.

printf void printf(string format, args...) Prints message to console with C style formatting. The line feed is not included.

printl void printl(string message) Prints message to console with a line feed after.

realPrint void realPrint(string message) Identical to print. print seems to be a wrapper for this.

Say void Say(CBasePlayer player, string message, bool teamOnly) Calling this will have the specified player send the message to chat, either to teamOnly (true) or to everyone.

ShowMessage void ShowMessage(string message) Displays a HUD message defined in scripts/titles.txt to all clients, similar to an env_message entity.

casti2f

float casti2f(int value)

Interprets the integer's bytes as if it were a floating-point encoding

Warning:This is a bit reinterpretation, i.e. 420 will not result in 420.0, it will be 5.88545e^-43! Use the tofloat() method for an actual conversion.
