Ball Physics

Hey,

How can I make a circle actor bounce up and down forever at the same height and if I move the ball left or right the bounce height will remain the same. If I bounce it onto a block then the height will increase with the same amount as the ball.
If anyone could help me that would be great.

Thanks

    The restitution of the ball and the platform it's bouncing on have to add up to 1. Pretty sure that should do the trick.

    I put them 0.5 each and it stopped after 2-3 bounces.

    I put the ball up to 1 and the platform to 0 and it did keep bouncing but it kept on getting higher and lower. Then when I changed the velocity to move it left or right it completely slowed down

    try putting both at .5, and make friction 0?

    I tried that
    didn't work

    what if they were both at 1? I havn't played much with the whole bouncing physics yet, so I'm just guessing here :)

    To get the ball to constantly bounce to the same height, set restitution of the ball to one, and set the max velocity to whatever you deem fit. Also check apply max velocity. Should do the trick.

    I don't think setting max velocity would work because I need it to move left and right with the accelerometer.

    You could just have the left and right movements adjusted with changing the x value.

    Nope setting max velocity still resulted in it slowing down

    my gravity is 500 but the problem is if I don't have any gravity the ball won't bounce at all

    What about a rule that says when ball collides with floor change velocity to (some speed) 90 to scene?

    Keep in mind that the GS collision detection is not perfect
