simulating a ball, friction problems

Getting Started

Hi,

I’m new to unity and to 3d/physics development generaly. I need to simulate a ball for a game I’m developping. But there’s something I don’t understand : when I put some friction between the ball and the terrain, the ball slows a lot. When the friction is applied to a sphere, shouldn’t it just rotate instead of slowing down ?

I also tried with just a little friction. In that case the ball would’t slow down that much so that was good, but it would’nt rotate much either.

I mean you would expect from a box that it stops with friction, but not a ball. A ball should react to friction by rotating.

I hope I made myself clear and understandable (probably not) and I hope there’s a solution out there :slight_smile:

Thanks in advance

what you are looking for is to add a rotation to the ball while it falls down.

as no forces are acting on the ball, just the gravity :slight_smile:

Try increasing max angular velocity in the physics settings. Normally this is limited to a quite small number, so things don’t rotate very quickly.

Perfect, that was the solution indeed, thanks.
