llPointAt(vector pos)
Depreciated in LSL. never implemented in OSSL.
Makes the object owner’s avatar point towards position pos. Use llStopPointAt to stop pointing.
Note: This function is still broken as of 1.6. It neither points nor faces pos.
According to Kelly Linden, llPointAt and llStopPointAt have been deprecated since mid-beta, but remain without a replacement to this day. (SL version 1.6)
