A filter is an entity that receives event triggering entities and filters them.

Here are all the filter entities:
==For Mappers==
* [[filter_activator_class]] - Filters according to the class of the activator.
* [[filter_activator_name]] - Filters according to the targetname of the activator.
* [[filter_activator_team]] - Filters according to the team of the activator.
* [[filter_combineball_type]] - Filters according to the type of the combine ball.
* [[filter_damage_type]] - Filters damage according to [[Damage Types|damage type]].
* [[filter_multi]] - Manages multiple filters.


For a more explanatory description of these filters, see [[Filter Applications]].
Filter entities can allow or disallow I/O or internal entity events with the following criteria:


;[[filter_activator_class]]
:[[Classname]] of the [[activator]].
;[[filter_activator_name]]
:[[Targetname]] of the activator.
;[[filter_activator_team]]
:[[Team]] of the activator.
;[[filter_combineball_type]]
:The type of <code>[[prop_combine_ball]]</code>.
;[[filter_damage_type]]
:Filters damage events by [[Damage Types|damage type]].
