I''m not moving at (x1,y1). I have a target at (x2,y2) that is moving at (S) speed in (D) direction (in radians). My bullet speed is 600 pixels per second. At what angle should I shoot to hit the target? Looking at your screen: Right is 0 radians Bottom is PI/2 radians Left is PI radians Top is 3PI/2 radians Thanks ______________________ Haydel
