Summary

Function: integer llGetParcelPrimCount( vector pos, integer category, integer sim_wide );
0.0 Forced Delay
10.0 Energy

Returns an integer that is the total land impact of objects 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 object land impact used on all parcels in the sim owned by the specified parcel's owner of the category requested.[1]
  • FALSE then the return is the object land impact used of the category requested on the parcel specified.

Category Description
PARCEL_COUNT_TOTAL 0 All objects on the parcel(s). Does not include temp on rez objects.
PARCEL_COUNT_OWNER 1 Objects owned by the parcel owner.
PARCEL_COUNT_GROUP 2 Objects not owned by the owner, but set to or owned by the group of the parcel.
PARCEL_COUNT_OTHER 3 Objects not set to group or owned by the owner.
PARCEL_COUNT_SELECTED 4 All objects selected or sat on.
PARCEL_COUNT_TEMP 5 All temp on rez objects.

Caveats

  • Temp mesh is not included in totals for PARCEL_COUNT_TEMP

  1. ^ Any value that is not zero/FALSE is treated the same as TRUE. This behavior should not be depended upon.

It's a dreadful night
