For Mappers

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 prop_combine_ball.
filter_damage_type: Filters damage events by damage type.

Filters can be mixed and matched with filter_multi.

For Programmers

A programmer does not need to use the filter entities above, since he or she already has direct access to all of the requisite data. Source's C++ filter classes are instead used to decide where data should be sent.
