/*SINED trigger_multiple (.5 .5 .5) ? x x NOT_PLAYERS MONSTERS PROJECTILES

Variable sized repeatable trigger.  Must be targeted at one or more entities.

If "health" is set, the trigger must be killed to activate each time.
If "delay" is set, the trigger waits some time after activating before firing.

"thread" name of thread to trigger.  This can be in a different script file as well\
by using the '::' notation.

"wait" : Seconds between triggerings. (.2 default)
"cnt" how many times it can be triggered (infinite default)

If NOT_PLAYERS is set, the trigger does not respond to players
If MONSTERS is set, the trigger will respond to monsters
If PROJECTILES is set, the trigger will respond to projectiles (rockets, grenades, etc.)

set "message" to text string
