Returns the UID of the first unit at the specified coordinates. Returns -1 if no unit was found at the coordinates.

In the case that there are multiple units on the specified location, this function will return the bottom-most unit. If, instead, you want to find all of the units at specified coordinates, you will have to use GAUIR. See examples at GetAllUnitsInRange.
