Made for AtomicBawm3, but usable for other purposes. A method for an enemy chasing the player- with both characters as one sprite, operating one script. Arrow keys to move player. Enemy will give chase. This actually took some time to make perfect, due to the duplicity of arctangent and the confusingness (I know that's not a word) of scratch's directional system (angle in scratch plane = 90 - angle in cartesian plane). For some reason the ghost looks 3Dish o_O
