|
// Purpose: Filters are outboard entities that hold a set of rules that other
|
|
// entities can use to determine behaviors.
|
|
//
|
|
// For example, triggers can use an activator filter to determine who
|
|
// activates them. NPCs and breakables can use a damage filter to
|
|
// determine what can damage them.
|
|
//
|
|
// Current filter criteria are:
|
|
//
|
|
// Activator name
|
|
// Activator class
|
|
// Activator team
|
|
// Damage type (for damage filters only)
|
|
//
|
|
// More than one filter can be combined to create a more complex boolean
|
|
// expression by using filter_multi.
|
|
