Make Ball roll fully with torque

Simulate Physics with Torques

The UE4 Rolling Ball template has it fully implemented, using torque also opens up for the use of physical materials properly, which I’m almost certain you’d need, judging by the video. Because who doesn’t want to have a ball skid on ice?!

You can just duplicate it. If you don’t have / want UE4:

If you’re going to base the movement direction on the camera, use its right vector instead. It really depends on how you want the camera to work. Here’s an example for the cam following velocity:

How do I make a spring arm follow a velocity not a rotation

I’m trying to have a marble followed by a camera. I’d probably just have a springarm with Absolute Rotation follow Velocity (no Z): [334221-screenshot-1.png] [Image from Gyazo] Add a small lag value to rotation perhaps.

But you may want another solution, ofc.

Here’s a 7 year old (!) example how to use the Right Vector I mentioned above:

It could be as simple as this: [image] But may need to be adjusted depending on what else is needed: but adding torque in the right direction is where Im having trouble You, kind of, solved it yourself - the Right Vector is key when working with torque.

Good luck!
