That's a nice example. I especially like the smooth rotation instead of instantly pointing at the mouse.
this helps, but im looking to replicate the car movements up arrow function. accelerating towards the direction the sprite is facing..which would be sprite.angle. but i dont know how to addd that speed. i tried everything in the physics section and some in the other
