I'm trying to make a game where a ball will fall with gravity, and will bounce off of the platforms in its way. I'm pretty sure I can figure out the x component with the different angles, but I'm having issues getting the ball to bounce off of the platform. I have it checking when the ball collides with the platform, but then I want it to stop, and move it in the opposite direction with less speed. Please help me anyone, especially Danpost.
