This method uses a loop, it is less efficient and only included for completeness. It's more efficient to ask the physics engine (via [[llGetObjectPrimCount]]) how many prims are in the object. This only works if the object is not attached, but fortunately, in that situation you can use llGetNumberOfPrims since avatars cannot sit on attachments (the feature was removed during beta).

Summary

Function: integer llGetNumberOfPrims( );

Returns an integer that is the number of prims in a link set the script is attached to.

Caveats

  • The number of prims returned also includes the number of avatars sitting on the object.
