/*****************************************************************************/
/*QUAKED trigger_multiple (1 0 0) ? x x NOT_PLAYERS MONSTERS PROJECTILES SCRIPTSLAVE

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

If "delay" is set, the trigger waits some time after activating before firing.

If "destructible" is set, the trigger will take damage and lose health.
If "triggerondamage" is set, trigger will fire when ever it takes damage.
If "triggerondeath" is set, trigger will fire when it dies.  This forces destructible
to be on, since it would otherwise never die.
If "instantdeath" is set, trigger will die when it takes damage of this type.

To make a trigger fire every time it takes damage set triggerondamage to true.  To make a 
trigger fire everytime it takes damage and to eventually die, set triggerondamage
to true, destructible to true, and give it a health.  To make a trigger that
triggers on death only, set triggerondeath to be true.  This will also turn
on destructible.  To make a trigger that triggers everytime it takes damage
and when it dies, set both triggerondamage to be true and triggerondeath to
be true.

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

if "angle" is set, the trigger will only fire when someone is facing the
direction of the angle.
"cone" the cone in which a directed trigger can be triggered (default 60 degrees)

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

"triggerable" turn trigger on
"nottriggerable" turn trigger off

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.)
if SCRIPTSLAVE is set, the trigger will respond to script slaves

set "message" to text string

AMBIENT-ON specifies an ambient sound that starts on
AMBIENT-OFF specifies an ambient sound that starts off
TOGGLE specifies that the speaker toggles on triggering

if (AMBIENT-?) is not set, then the sound is sent over explicitly this creates more net traffic

"volume" how loud 0-4 (1 default full volume, ambients do not respond to volume)
"noise" sound to play
"channel" channel on which to play sound\

"key" The item needed to activate this. (default nothing)
"thread" name of thread to trigger.  This can be in a different script file as well\
by using the '::' notation.

Normal sounds play each time the target is used.

Ambient Looped sounds have a volume 1, and the use function toggles it on/off.
