filter_damage_class

filter_damage_class is a point entity available in Black Mesa. It is a damage filter that filters specified attacker, weapon class, NPC type, etc. Works only with classname and not targetname. Useful when you need to prevent taking damage from some NPC or weapon. For example, prevent a board from taking damage from anything with exception of crowbar, or allow a HECU soldier to die from anything with exception of other soldiers.

Filter Classname (filterclass) <string>

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

BaseFilter:

Filter mode (Negated) <boolean>

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

Flags

•  [1] : Check against attacker
•  [2] : Checks against inflicter

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.  [todo tested in?]

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.
