tank_boss
... 
tank_boss is a point entity available in 
Team Fortress 2.
Bug:If there are no path_tracks present in the map, the game will crash.Bug:Tanks pass through any walls with a transparent texture (grates, glass, etc.) or tool textures but not tools/toolsblack, tools/toolsnodraw and tools/toolsskybox.
Tying the wall into an entity doesn't prevent this. (Except for func_detail.)
In code, it is represented by theCTFTankBossclass, defined in thetf_tank_boss.cppfile.Contents
Entity description
The tank used in Mann vs Machine missions. When spawned in by a popfile, it will start at the path_track entity specified by the popfile and continue until it reaches the end of the path, where it will deploy the bomb. When destroyed, it creates a tank_destruction entity.
Note:When spawned using ent_create, the tank will attempt to travel in a straight line toward the bomb hatch from the point it was spawned at.Keyvalues
- Health
(???)<integer> - Health of the tank.
- Model
(???)<string> - Model the tank uses.
- Speed
(???)<integer> - Speed the tank travels at, higher speeds can cause the tank to clip through geometry.
- Start Disabled
(???)<boolean> - Start disabled.
- TeamNum
(???)<choices> - Team.
BaseFadeProp:
- Start Fade Dist
(fademindist)<float> - Distance at which the entity starts to fade.
- End Fade Dist
(fademaxdist)<float> - Max fade distance at which the entity is visible.
- If start fade is <0, the entity will disappear instantly when end fade is hit.
- If end fade is <0, the entity won't disappear at all. (This is the default behavior.)
- The values will scale appropriately if the entity is in a 3D Skybox.
- Fade Scale
(fadescale)<float> - If you specify so in
worldspawn, or if the engine is running below DirectX 8 (DX7 in
), props will fade out even if the fade distances above aren't specified. This value gives you some control over when this happens: numbers smaller than 1 cause the prop to fade out at further distances, while those greater than 1 cause it to fade out at closer distances. Using 0 turns off the forced fade altogether. See also the QC command $noforcedfade.
Base:
- Parent
(parentname)<targetname> - Maintain the same initial offset to this entity. An attachment point can also be used if separated by a comma at the end. (
parentname [targetname],[attachment])
Tip:Entities transition to the next map with their parentsTip:phys_constraintcan be used as a workaround if parenting fails.
- Origin (X Y Z)
(origin)<coordinates> - The position of this entity's center in the world. Rotating entities typically rotate around their origin.Note:Hammer does not move the entities accordingly only in the editor.
- Pitch Yaw Roll (X Y Z)
(angles)<angle> - This entity's orientation in the world. Pitch is rotation around the Y axis, yaw is the rotation around the Z axis, roll is the rotation around the X axis.Note:This works on brush entities, although Hammer doesn't show the new angles.
- Classname
(classname)<string> !FGD - Determines the characteristics of the entity before it spawns. Tip:Changing this on runtime still has use, like making matching an entry in S_PreserveEnts will persist the entity on new rounds!
- Spawnflags
(spawnflags)<flags> !FGD - Toggles exclusive features of an entity, its specific number is determined by the combination of flags added.
- Effects
(effects)<flags> !FGD - Combination of effect flags to use.
- Entity Scripts
(vscripts)<scriptlist> (in all games since
) (also in ) - Space delimited list of VScript files (without file extension) that are executed after all entities have spawned. The scripts are all executed in the same script scope, later ones overwriting any identical variables and functions. Scripts executed on the worldspawn entity will be placed in root scope.
- Think function
(thinkfunction)<string> (in all games since) (also in ) - Name of the function within this entity's script that'll be called automatically every 100 milliseconds, or a user-defined interval if the function returns a number. Avoid expensive operations in this function, as it may cause performance problems.
- Lag Compensation
(LagCompensate)<boolean> (in all games since) !FGD - Set to Yes to lag compensate this entity. Should be used very sparingly!
- Is Automatic-Aim Target
(is_autoaim_target)<boolean> (in all games since
) !FGD - If set to 1, this entity will slow down aiming movement for consoles and joystick controllers when the entity is under the crosshairs.
Inputs
SetSpeed- Set the speed of the tank. Must be a positive value. Note:High values will cause the tank to have difficulties navigating the path_tracks.
SetHealth- Set the tank's health.
SetMaxHealth- Set the tank's max health.
AddHealth- Add health to the tank.
RemoveHealth- Remove health from the tank.
Bug:Changes to the tank's health will not be reflected in the HUD until the tank is damaged by a player.DestroyIfAtCapturePoint- Destructs the tank if it reached its final path_track node.
AddCaptureDestroyPostfix- Sets the tank's destruction animation name's postfix. Can be used for these destruction animations.
SetTeam<integer>- Changes the entity's team.
0: Any
2: Red
3: Blue
Ignite- Ignite, burst into flames.
IgniteLifetime<float>Ignitewith the given lifetime.
Todo: Before the flames extinguish, or before health reaches zero?
IgniteNumHitboxFires<integer>Ignitewith the given number of hitbox fires.
IgniteHitboxFireScale<float>Ignitewith the given hitbox fire scale.
Base:
AddContext<string>- Adds to the entity's list of response contexts. See Context.
AddOutput<string>- Assigns a new keyvalue/output on this entity. For keyvalues, some rely on extra necessary code to be ran and won't work if its simply just changed through this input. There is a strict format that must be followed:
// Format of changing KeyValues: "AddOutput [key] [value]"
//// Raw text:
"OnUser1" "!self,AddOutput,targetname new_name"
// Format of adding an Output: "AddOutput {targetname}:{inputname}:{parameter}:{delay}:{max times to fire, -1 means infinite}"
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:SetParent:!activator:0.0:-1"
// Arguments can be left blank, but the empty blank should still be contained.
//// Raw text:
"OnUser1" "!self,AddOutput,OnUser1:ClearParent::0.0:-1"
|
ClearContext- Removes all contexts from this entity's list.
ClearParent- Removes this entity from the the movement hierarchy, leaving it free to move independently.
FireUser1toFireUser4- Fires the respective
OnUseroutputs; see User Inputs and Outputs.
Kill- Removes this entity and any entities parented to it from the world.
KillHierarchy- Functions the same as
Kill, although this entity and any entities parented to it are killed on the same frame, being marginally faster thanKillinput.
RemoveContext<string>- Remove a context from this entity's list. The name should match the key of an existing context.
SetParent<string>- Move with this entity. See Entity Hierarchy (parenting).
SetParentAttachment<string>- Change this entity to attach to a specific attachment point on its parent. The entity will teleport so that the position of its root bone matches that of the attachment. Entities must be parented before being sent this input.
SetParentAttachmentMaintainOffset<string>- As above, but without teleporting. The entity retains its position relative to the attachment at the time of the input being received.
DispatchResponse<string> !FGD- Dispatches a response to the entity. See Response and Concept.
DispatchEffect<string> (removed since
) !FGD- Dispatches a special effect from the entity's origin; See also List of Client Effects. Replaced by the particle system since .
RunScriptFile<script> (in all games since) (also in )- Execute a VScript file from disk, without file extension. The script contents are merged with the script scope of the receiving entity.
RunScriptCode<string> (in all games since) (also in )- Execute a string of VScript source code in the scope of the entity receiving the input. String quotation may be needed when fired via console. Bug:In Hammer, using string arguments will corrupt the VMF file's structure, making the file unviewable for the next Hammer session.Fix:Remove the string argument manually with a text editor.Note: Backtick characters ` are replaced with quotation marks at runtime, allowing quotation marks to be used when normally not possible.
CallScriptFunction<string> (in all games since) (also in ) !FGD- Calls a VScript function defined in the scope of the receiving entity.
TerminateScriptScope(only in) !FGD- Destroys the script scope of the receving entity.
SetLocalOrigin<coordinates> (in all games since
) !FGD- Send this entity to a spot in the map. If the entity is parented to something, it will be offset from the parent by this amount.
