Description

Event: collision_start( integer num_detected ){ ; }

Triggered when task starts colliding with another task

• integer num_detected

Caveats

  • Will not detect collisions with ground. Use land_collision_start instead.
  • Phantom objects can never receive trigger collision events.
  • llVolumeDetect(TRUE) objects get trigger collision_start and collision_end but not collision() events.
  • A collision with a hovering avatar does not trigger collisions, unless the avatar turns or moves.
  • Only a physical object will get collision events from colliding with a non-physical object.
