I am making a Atari Breakout game with unitys 2d tools and I need to get the ball to bounce of colliders in the scene. If you havent played the game before how it works is if the ball hits the wall at 45 degrees it will bounce of the wall at the same angle (diagram bellow)
How can I get the ball to move at a continues speed and when it hits a collider to bounce back the way the image shows?
