Function: llCollisionFilter( string name, key id, integer accept );

Sets the collision filter, exclusively or inclusively.

• string name
• key id
• integer accept

if accept == TRUE, only accept collisions with objects name and id (either is optional), otherwise with objects not name or id


Stop filtering: <lsl>llCollisionFilter("", NULL_KEY, TRUE);</lsl> Filter out all collisions: <lsl>llCollisionFilter("", NULL_KEY, FALSE);</lsl>

Complete script whit llcollisionfilter
