as far an a standered equation .... it does exisit esp considering everyone has diffrent img sizes , its not like getting the x and y of directly in front of a player which pretty much everyone uses the same one cause player size doesnt change , unless your using kingdom bodies, but never the less if its a new equation you have to just figure out an equation that will support what your tring to do, which can be done by a vast knowledge of math or trial and error process
