Im trying to set player controlled character in the game constantly face the mouse. I managed to get the angle working well except that towards the edges of the screen, as in the surface the object is blited onto, it seems to get progressively less and less accurate. it rotates allot less and seems to want to face the center of the screen. In the middle of the screen the object rotates almost perfectly.
Edit: It doesnt actually seem to want to face the center, it wants to face the original point that it blited into, rather then the place it is currently in.

(i left out the whole menu script it seemed unnecessary.) Ive tried adjusting the values in the angle calculation and this game isnt really going to be viable without a moving character.
My end goal is to have the character perfectly synced to the mouse, or atleast as perfect as possible.
