UsedOnMe
UsedOnMe, ObjectID
Where: ObjectID = Object to test for use
Type: Object, Broken
Returns: short
Example: if ( UsedOnMe, Misc_pot_redware_01 == 1 )
Scripts: UsedOnMe (commented out saying it was crashing)
Returns 1 if the given ObjectID is used on the calling object, or 0 otherwise. It appears that this function is currently broken. UsedOnMe is probably commented out because there's no way for an object to be used on another in the Morrowind engine. I suspect that it was early alpha stuff.
