filter_base is a point entity available in all Source games. This entity class defines the common functionality shared by all filter types. This entity technically can't filter anything on its own. Every entity is accepted (or rejected, if Negated is set).

Keyvalues

Name (targetname) <string>

The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

BaseFilter:

Filter mode (Negated) <boolean>

Inverts the filter, making the specified criteria fail and all others pass.

Inputs

BaseFilter:

TestActivator

Tests the entity that called the input (the !activator) against the filter, and fires either the OnPass or OnFail output.

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.

FGD Code

Paste to base.fgd:

@FilterClass base(BaseFilter) iconsprite("editor/filter_multiple.vmt") = filter_base : "A filter that accepts or rejects everything."
