llGetNumberOfPrims

Summary

Function: integer llGetNumberOfPrims( );

275	Function ID
0.0	Forced Delay
10.0	Energy

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.

Examples

<lsl>default {

   {
       llOwnerSay((string)llGetLinkNumber());
       llOwnerSay((string)llGetNumberOfPrims());
   }

}</lsl>

Useful Snippets

<lsl> // Returns the number of prims in the object, ignoring seated avatars integer GetNumberOfPrims() {

   if (llGetAttached())
   {
       // llGetObjectPrimCount fails on attachments, but you can't sit on an attachment
       return llGetNumberOfPrims();
   }
   return llGetObjectPrimCount(llGetKey());

}

//-- inline version of the above (llGetObjectPrimCount( llGetKey() ) + llGetNumberOfPrims() * !!llGetAttached())

// Returns the number of agents on the object integer GetNumberOfAgents() {

   return llGetNumberOfPrims() - GetNumberOfPrims();

}

//-- inline version of the previous ((llGetNumberOfPrims() - llGetObjectPrimCount( llGetKey() )) * !llGetAttached()) </lsl> 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. <lsl> // determine the number of prims in linkset integer getNumberOfPrims() {

   integer maxLinkNumber = llGetNumberOfPrims();
   // subtract seated avatars
   while( llGetAgentSize( llGetLinkKey(maxLinkNumber) ) ) {
       --maxLinkNumber;
   }
   return maxLinkNumber;

} // END getNumberOfPrims() </lsl>
