# OVERVIEW
|
|
Point based trigger. Define a radius and it will fire its targets when an entity touches
|
|
it within that radius.
|
|
|
|
# KEYS
|
|
- "targetname" : Name
|
|
- "target" : Target when triggered.
|
|
- "TriggerOnce" : Either 0 (Multiple) or 1 (Once).
|
|
- "TriggerRadius" : Radius in Quake units.
|
|
|
|
# INPUTS
|
|
- "Toggle" : Toggles it between disabled and enabled states.
|
|
|
|
# OUTPUTS
|
|
- "OnStartTouch": Triggered when something starts touching this volume
|
|
- "OnEndTouchAll": Triggered when nothing touched the entity no more
|
|
|
|
# SPAWNFLAGS
|
|
- CLIENT (1) : Make this explosion purely decorative, without radius damage.
|
|
- NPC (2) : Makes this explosion triggerable more than once.
|
|
- PUSHABLE (4) : Spawn no fireball.
|
|
- PHYS (8) : Spawn no smoke.
|
|
- ALLIES (16) : Leave no decal upon explosion.
|
|
- VEHPLAYER (32) : Don't spawn any sparks upon exploding.
|
|
- ALL (64) : Don't spawn any sparks upon exploding.
