Hello, I have a game where you can control the rotation of the floor with your mouse and there is a ball rolling on top. The problem I have come across is that the ball will stop rolling even though there is a slope.

As you can see, I angle the floor more and more, but the ball will move for a split second, then stop.

The other problem Im having is if I keep the ball moving, it moves too fast. Ive changed the max angular velocity but that didn’t change anything.

The default rolling ball template should do this for you, but it sounds like you’ve tweaked the friction coefficient?..

I actually was able to find the answer from someone else.

To fix the speed I had forgotten to make sure the mass was correct as mine was too high. Then I increased the liner drag (dampening) .

Then for the ball stopping on the slope, it was due to the ball being put to sleep so I had to set the sleep family to custom and set the sleep threshold to 0.
