filter_activator_class is a point entity available in all Source Source games. It is a filter that checks the classname (keyvalue) of the activator.

Tip.png Tip: Using the AddOutput input, it is possible to change the classname of an entity. This changes what filters see, but not the functionality of the entity, as long as the player does not save and reload the map after changing the classname.
In code, it is represented by theCFilterClassclass, defined in thefilters.cppfile.

Keyvalues

Filter Classname (filterclass) <string>
The classname to filter by.

BaseFilter:

Filter mode (Negated) <boolean>
Inverts the filter, making the specified criteria fail and all others pass.

Targetname:
Name (targetname) <string>
The targetname that other entities refer to this entity by.

Inputs

BaseFilter:

TestActivator
Tests the entity that called the input (the !activator) against the filter, and fires either the OnPass or OnFail output.
Bug.png Bug: Calling this input will cause the server to crash if the !activator entity no longer exists. Do not use this input to test any entities which may be asynchronously deleted, such as players or projectiles, or in an i/o chain which might be initiated by entity deletion, such as the OnEndTouch output of a trigger.

Outputs

BaseFilter:

OnPass
OnFail
One of these will fire when TestActivator input is sent, depending on if the activator is allowed by the filter or not.
