Determines the creature that is going to attack another creature in the current combat round.
The creature that is going to be attacked.
Returns the creature that is going to attack oTarget, and OBJECT_INVALID if oTarget is not a valid creature or if oTarget isn't being attacked.
This value is cleared out at the end of every combat round and should not be used in any case except when getting a "going to be attacked" shout from the master creature (and this creature is a henchman).
