I have question does anyone have a good way to make a boulder roll down a platform? I can get it to roll initially, but cannot get it to move after that. I tired using the simulate control with a invisible detector to trigger the control change, but nothing happens.
To apply rolling force to an object you need to use the apply torque force so it spins the boulder if is on a horizontal plane.
if is a slope platform the physics behavior should do its job.
