tanktrain_ai

tanktrain_ai is a point entity available in all Source games. This is AI to make an associated func_tanktrain automatically move along its path towards the node closest to a target.

Bug:The train won't move any faster than 1 unit per second due to coding mistakes.

Keyvalues

Train Name <targetname>

The func_tanktrain to move

Start Moving Sound <sound>

The sound to play when the train starts moving

Engine Loop Sound <sound>

The engine sound is looped when it plays

Vehicle Movement Sound <sound>

The looping sound to play while the train is moving

Targetname:

Name (targetname) <string>

The targetname that other entities refer to this entity by.

Inputs

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.

FireUser1 to FireUser4

Fires the respectiveOnUseroutputs; 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.

Use  !FGD

Same as a player invoking +use; no effect in most cases.

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.

SetLocalAngles <angles> (in all games since ) !FGD

Set this entity's angles.

TargetEntity <string> !FGD

Start chasing the entity with this name

Outputs

Targetname:

OnUser1 to OnUser4

These outputs each fire in response to the firing of the like-numbered FireUser1 to FireUser4 Input; see User Inputs and Outputs.

OnKilled  (only in )

This output fires when the entity is killed and removed from the game.
