Breakout Bounce Physics

Recommended Posts

I found a lot of articles about creating a breakout arkanoid-like game, but in all of them, when the ball hit the paddle, it only inverted the Y-speed and continued as though it would hit a wall. However, in commercial Arkanoid-like games, the angle and the speed of the ball bouncing off the paddle depend on where the ball hit the paddle (on the edge, left, center...). Could you help with that? What should be the ball's angle and speed when it bounces off?

If I remember my Atari days correctly, the ball would get a little velocity on the x-axis added to it depending on how quickly you moved the paddle at the time of contact; also it would speed up in general whenever you hit a brick. I doubt they did anything more complex than:



void hit_a_brick() {
velocity *= 1.1;
}

void hit_the_paddle() {
velocity.x += paddle.velocity.x;
}
