Summary

Function: integer llGetParcelPrimCount( vector pos, integer category, integer sim_wide );

Returns an integer that is the number of prims on the parcel at pos of the given category

• vector pos position in region coordinates (z component is ignored)
• integer category a PARCEL_COUNT_* flag
• integer sim_wide boolean, TRUE[1] searches parcels in the region with the same owner as the targeted parcel, FALSE searches only the targeted parcel

Specification

If sim_wide is...

  • TRUE then the return is the combined number of prims on all parcels in the sim owned by the specified parcel's owner of the category requested.[1]
  • FALSE then the return is the number of prims of the category requested on the parcel specified.
