Summary

Function: list llGetParcelPrimOwners( vector pos );

Returns a list of all residents who own objects on the parcel at pos and with individual land impact used.
The list is formatted as [ key agentKey1, integer agentImpact1, key agentKey2, integer agentImpact2, ... ], and sorted by agent key with a maximum of 100 strides.

• vector pos position in region coordinates

Requires owner-like permissions for the parcel.

Specification

Ownership

  • If the parcel owner and object owner are the same (including if the object and parcel are both group owned):
    • All object owners are returned.
  • If the parcel is group owned but the object is owned by a member of the group, the function return depends upon what powers they have been granted:
    • If resident has the 'return group owned objects' power:
      • The return list includes the group and the LI of objects it owns on the parcel.
    • If the resident has the 'return group set objects' power:
      • The return list includes all owners who have objects set to the group on the parcel
    • If the resident has the 'return non-group objects' power
      • The return list includes all owners of objects that don't fall into the above two categories.
  • If none of the above cases match, an empty list will be returned.
Pseudocode
Pseudocode written in Javascript
if(parcel_owner == object_owner)
    return all;
var r = [];
if((parcel_owner is Group) && (object_owner in parcel_owner.members))
{
  if("return group owned objects" in parcel_owner.members[object_owner].powers)
    r = r.concat(group_owned_stride);
  if("return group set objects" in parcel_owner.members[object_owner].powers)
    r = r.concat(group_set_strides);
  if("return non-group objects" in parcel_owner.members[object_owner].powers)
    r = r.concat(non_group_strides);
}
return r;

Caveats

  • This function causes the script to sleep for 2.0 seconds.
  • Function WILL NOT work on group owned land if the owner of the object where this function resides is not currently online and connected to the sim (although now seems to be working for land owner on privately owned land even when the owner is not around).
    • These limitation can be overcome by deeding the object to a group the object owner is one of the owners of.
    • Remember to take a copy before deeding because you cannot undeed something.

Examples

Show a comma separated list of user IDs and their prim counts. key1, count1, key2, count2 .... etc.

default
{
    state_entry()
    {
        list TempList = llGetParcelPrimOwners( llGetPos() );
        llSay(0, llList2CSV(TempList) );
    }
}

Use floating text to show prim owner names and counts in count order

// Show a floating text list of prim owners on this parcel,
// Sorted by prim count per owner. Highest users first.
// Omei Qunhua
 
// The object has the same permisions to view prim parcel owners
// as its owner (In About Land >> Objects >> Object Owners )
 
// Example: If you can't return group object, you won't see group objects
// If you can't return any objects, an empty list will be returned.
// If the prim is deeded to the right group, it should always get a full list
 
// Note: Only works on group owned land when the object owner is in the Sim
//       Deeded objects always work (group is always online?)
