As an option, hang a raycast down script on the desired object, and watch the result (this is for the unit, but I think it is suitable for all engines). well, or just in each frame to process the comparison of the z axis of objects

If there are not many objects, then you can use Vector2.Distance between the positions of objects, excluding the coordinates along the Y axis.
Rather, it would be better to calculate Vector2.sqrMagnitude - faster.
