Filter name.png
filter_activator_name is a point entity available in all Source games. It is a filter that filters by the targetname of the activator.


Filter Name <targetname>
The name to filter by. If the filter mode is Allow, only entities whose name matches the given string will pass the filter. If the filter mode is Disallow, all entities EXCEPT those whose name matches the string will pass the filter.


Negated <bool>
Inverts the filter, making the specified concept fail and all others pass.


Name <string>
The targetname that other entities refer to this entity by.
Entity Scripts <scriptlist> (New with Left 4 Dead 2)
Name(s) of script files that are executed after all entities have spawned.
Script think function <string> (New with Left 4 Dead 2)
Name of a function in this entity's script which will be called automatically every 100 milliseconds (ten times a second) for the duration of the script. It can be used to create timers or to simulate autonomous behavior.
Note:Try to avoid expensive operations in this function, as it may cause performance problems.



Tests the entity that called the input (the !activator) against the filter, and fires either the OnPass or OnFail output.
Calling this input from the OnEndTouch output of a trigger will crash the server if a client disconnects within it!


Removes this entity from the world.
Removes this entity and all its children from the world.
AddOutput  <string>
Evaluates a keyvalue/output on this entity. It can be potentially very dangerous, use with care.
Format: <key> <value>
Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>
FireUser1 to FireUser4
Fire the OnUser outputs; see User Inputs and Outputs.
Use  !FGD
Same as a player invoking +use; may not do anything. Can also be invoked by creating an output that does not specify an input.
This input is not included in Valve's FGDs.
RunScriptFile  <script> (New with Left 4 Dead 2)
Execute a game script file from disk.
RunScriptCode  <string> (New with Left 4 Dead 2)
Execute a string of script source code. String quotation may be needed when fired via console.
Note:The code is executed in the script scope of the entity that fires the output, not the one of the targeted entity.
Warning:Never try to pass string parameters to a script function with this input. It will corrupt the VMF structure because of the nested quotation marks, which then must be removed manually with a text editor.
CallScriptFunction  <string> (New with Left 4 Dead 2)
Execute a game script function.



Fired if in response to the TestActivator input.
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.

(New with Left 4 Dead)

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