View source for How to point a sprite at a target

To point a [[Sprite|sprite]] at a target, use the [[atan]] function to calculate the angle in radians, then multiply by 180/[[pi]] to convert to degrees, and assign the result to the sprite's [[Sprite.rotation|.rotation]] property.

See also [[How to move a sprite towards a target]].

== Example ==
This example loads an arrow sprite, and makes it continuously point at the mouse.  Press Control-C to exit.

<ms>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</ms>
