Description
Event: collision_start( 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.
Examples
default
{
collision_start(integer num)
{
llSay(0,"No pushing.");
}
}
