NOTE: Because LsL does not reset a script when it is transferred to a new owner, a script can retain old owner identity and even act upon the old owner unless the script is reset. While this appears up front to be a problem with llGetOwner(), this is not the case. The script must be reset upon owner change, which is most easily accomplished using the CHANGE event, as demonstrated below. Without such a reset event, significant problems can be experienced especially in the use of animations and other functions which act upon the owner of the device.

Summary

Function: key llGetOwner( );

Returns a key that is the current owner of the script.

Caveats

  • When the owner of an object changes, code that depends on this function's return value will not automatically update for the new owner or be automatically re-evaluated.
    • This requires the reregistration of listens and requesting of permissions from the new owner as needed.
    • Detection of owner change can be achieved with the changed event in conjunction with the CHANGED_OWNER flag (see the first example) or by storing the old value and periodically (on_rez) checking if it has changed. Both techniques are valid though the latter will not detect the sale of the object if it is sold as original in world and not picked up.
