    Hi, I’m using a null’s rotation to animate the parabolic path of a ball. I’d like the ball to bounce which requires I rotate around a new axis.

    Is it it possible to “expand” the rotation data of null into rotation and position for the ball?

    If I’m following you correctly, you’re ball is parented to a null and offset so that when the null rotates the ball moves in an arc, right?

    Personally that doesn’t sound like a great way to do it. First of all, those arcs will not be parabolic, just round. Second, what’s so hard about using position keyframes? Using bezier curves with handles, you can basically draw a path with way more control then your current method.

    Unless I missed something.

    Or you can try doing it with expressions. Here’s a thread from the Cow where you can find the expression scripts and explanation:
