Could you explain further what it does? personally I don't really know what's happening

The variable vy (Vertical Velocity in this case) determines the vertical direction and speedof the ball. When the ball collides with the paddle it checks where on the paddle it has collided; the higher up the collision was the lower it sets the velocity, the lower the collision was the higher it sets the velocity.

Instead of making multi hitboxes just conver rad to deg and using arctan2.

Code: Select all

degree = radtodeg(arctan2(vec1.y - vec2.y, vec2.x - vec1.x));

(not lua) but lua should have radtodeg and arctan2 functions.
