{{toc-right}}

{{sq}} This list contains the engine-related Squirrel classes, functions and variables available for [[VScript]] in {{game name|name=Team Fortress 2}}. 

The official documentation can be printed in the console by setting <code>developer</code> to non-zero, loading a map, and executing <code>script_help</code>. However, this documentation is very incomplete and most methods are not listed, requiring them to be found by other means instead.

{{warning|This page is still work-in-progress, many functions lack documentation and testing.}}
{{note|Most of these functions were dumped externally as they are not exposed by normal means. For these functions, the return is unknown and the arguments may not be fully correct.}}
{{tip|Tutorial on setting up Visual Studio Code (VSCode), including auto-completing of VScript functions, can be [[Setting_Up_VScript_in_Visual_Studio_Code|found here]].}}

=== Constants ===
A [https://en.wikipedia.org/wiki/Constant_(computer_programming) constant] is a variable whose value cannot be altered during program runtime, usually made to rid any instances of [https://en.wikipedia.org/wiki/Magic_number_(programming) magic numbers] by giving them self-documenting names.

=== Enums ===
:''See [[/Constants|this page]] for all enums under the <code>Constants</code> table.''

There are also [https://en.wikipedia.org/wiki/Enumerated_type enums] kept within the <code>Constants</code> table, all with their own constants. For an example of accessing an enum's constant, the <code>HIDEHUD_CROSSHAIR</code> constant of the enum <code>HideHUD</code> is accessed by doing ''<code>Constants.HideHUD.HIDEHUD_CROSSHAIR</code>''.

== 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:
* <code>[[#CEntities|Entities]]</code> instance.
* [[Entity Scripts]] only - The <code>self</code> keyword.

==== 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.

{| class="standard-table" style="width: 100%;"
! Function
! Signature
! Description
|-
| <code>Input[''InputName'']</code>
| <code>bool Input[''InputName'']()</code>
| Called when the entity receives an input from the I/O system that matches the function's name. The name of the function needs to be<code>Input</code>followed by the name of the input with the same casing (PascalCase). E.g. for the FireUser1 input, it would be<code>InputFireUser1</code>.

When the function is called, Script Handles of the activator and caller entities are accessible to the function under the variables<code>activator</code>and<code>caller</code>. The function needs to return a boolean value; Returning<code>true</code>processes the input, while<code>false</code>cancels it.
|-
| <code>OnGameEvent_''event_name''</code>
| <code>void OnGameEvent_''event_name''(table ''params'')</code>
| Called each time a game event with the specified name occurs. The name of the function needs to be <code>OnGameEvent_</code> followed by the name of the game event. E.g. for the player_spawn input, it would be <code>OnGameEvent_player_spawn</code>.

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 <code>userid, team, class</code>, while the deadringer_cheat_death event passes a table with the keys <code>spy, attacker</code>.

See [https://wiki.alliedmods.net/Team_Fortress_2_Events this page] for a list of game events as well as the table passed on each event.

''Scripts containing OnGameEvent should also issue a call to the function __CollectGameEventCallbacks in order to work properly''
|-
| <code>OnPostSpawn</code>
| <code>void OnPostSpawn()</code>
| Called after the entity spawns, which is after scripts and players have loaded. This could be used to have an entity register itself with a master script, or adjusting the entity parameters in a programmatic way.
|-
| <code>Precache</code>
| <code>void Precache()</code>
| Called after the script executes. Can be used to call precache functions for models and sounds on map load.
|-
| <code>OnTakeDamage</code>
| <code>void OnTakeDamage(handle ''params'')</code>
| Called each time an entity takes damage. The script can modify the table entries not suffixed with ''const'', and these will be sent back to the game code. 
{{note|This is a special "entity hook" and works differently than the other hooks, see the example below for how to set it up.}}

=== Convars ===
Game Instance: <code>Convars</code>

Provides an interface for getting and setting [[Convar|convars]] on the server.

{{note|Protected convars (e.g. <code>rcon_password</code>) cannot be accessed.}}

==== Methods ====
{| class="standard-table" style="width: 100%;"
! Function
! Signature
! Description
|-
| <code>GetBool</code>
| <code>bool GetClientConvarValue(string ''name'')</code>
| Returns the convar as a bool. May return null if no such convar.
|-
| <code>GetClientConvarValue</code>
| <code>string GetClientConvarValue(string ''name'', int ''entindex'')</code>
| Returns the convar value for the entindex as a string. Only works on client convars with the FCVAR_USERINFO flag. 
|-
| <code>GetInt</code>
| <code>int GetInt(string ''name'')</code>
| Returns the convar as an int. May return null if no such convar.
|-
| <code>GetStr</code>
| <code>string GetStr(string ''name'')</code>
| Returns the convar as a string. May return null if no such convar. 
|-

| Returns the convar as a float. May return null if no such convar.
|-
| <code>IsConVarOnAllowList</code>
| <code>bool IsConVarOnAllowList(string ''name'')</code>
| Checks if the convar is allowed to be used and is in cfg/vscript_convar_allowlist.txt. 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!
|-
| <code>SetValue</code>
| <code>void SetValue(string ''name'', ''value'')</code>
| 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. Supported types are bool, int, float, string.
|}

=== CEntities ===
Game Instance: <code>Entities</code>

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:

{| width=100%
|- style="vertical-align:top;"
|
<source lang=js>
local ent = null;
while ( ent = Entities.FindByClassname(ent, "tf_weapon_*") )
{
  // ...
}
</source>
|
<source lang=js>
for (local ent; ent = Entities.FindByName(ent, "tf_weapon_*"); )
{
  // ...
}
</source>
|}

{{Note |
* The variable name <code>ent</code> is arbitrary.
* Indeed, we mean "{{=}}" and not "{{=}}{{=}}" in the loop conditions! The loops end if <code>ent</code> becomes <code>null</code>, 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 <code>for</code> statement.
* The string parameters of the <code>FindBy...</code> functions support the wildcard star <code>*</code>. In the above example, <code>FindByClassname</code> only returns either a handle of an entity whose classname begins with "<code>tf_weapon_</code>" or it returns <code>null</code>.

Spawned entities can be accessed synchronously in script by using an entity maker. The following generalised example creates a global <code>SpawnMyEntity()</code> function which spawns and returns the templated entity. It can be modified to support multiple templated entities.
{{ExpandBox|<source lang=cpp>
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)
</source>}}

Spawn templated entities from any script.
{{ExpandBox|<source lang=cpp>
local ent = SpawnMyEntity( {
