I have a question on how to calculate a way im moving the mouse for a 2d shooter. Say, if i move the mouse upwards to the right, i want my ship to fire that way, for an example from the middle of the screen to the upper right at a 45 degree angle. I must be able to do this for a full 360 degrees. Anyone have any pointers?

Thanks, only one problem, my sprite points the right way when moving left and right. But if i move it from the center to the upper right, it points to the lower right, same with the other way around.. do you know why?

I noticed that if i pull the mouse down it has a rotation of 0 degrees, but if i pull the mouse up it shows a rotation of 180 degrees. Any way i can make it do the opposite?
