Making something roll...

HI guys, how do you make a circular ball actor roll? At the moment it just slides, obviously that doesn't look natural. I need it to rotate based on the direction and speed its rolling. Any ideas?
Cheers

    If you havent already, change its collision shape to a circle.

    Then try constraining its angular velocity to its linear velocity x

    just did that, it works, but it doesn't spin in the right direction, and it doesn't match the speed at which its travelling. Thx.

    constrain its angular velocity to -(self.motion.linear.velocity.x)

    then it will rotate the right way

    or you could just make a slope, and drop the ball actor onto it ( minimal friction, circular collision shape). It'll roll based on how your slope is inclined.
