WebApr 12, 2024 · Your second problem is that the values that atan2 correspond to don't match up with the directions you want. What you want is a circle where the top is 0°, the right side is 90°, the bottom is 180°, and the left side is 270°. Punching the values into atan2 is instead going to produce values where the right side is 0°, up is 90°, left is 180°, and down is 270°.
