This example loads an arrow sprite, and makes it continuously point at the mouse. Press Control-C to exit.
clear sp = new Sprite sp.image = file.loadImage("/sys/pics/arrows/arrow2.png") sp.x = 480 sp.y = 320 display(4).sprites.push sp while true // (press Control-C to exit) sp.rotation = atan(mouse.y - sp.y, mouse.x - sp.x) * 180/pi yield end while
