Hello,

I am trying for a long time to finish a clone of the game brick breaker.
I am having trouble with the speed of my ball, I searched all over the internet and could not get the desirable solution.
All I want is to make the ball move in constant velocity for all over the time without any changes.

When the ball is colliding with the paddle:

Vec2 vel = ballBody->getVelocity();
vel.x = (ball_center - paddle_center) * 7.5;
vel.y = -vel.y;
ballBody->setVelocity(vel);

When the ball is colliding with brick:

Vec2 vel = ballBody->getVelocity();
vel.x = vel.x;
vel.y = -vel.y;
ballBody->setVelocity(vel);

I tried almot everything.

Thanks for help!
