Animating A Rolling Ball

Support Basics & Interface
1

Hi

is it possible to get a rolling ball down a slope using physics and not keyframe animation?
i know you can do it in the game engine but i dont think you can render that.

Thanks for reading (and hopefuly helping)

Well it’s tricky - I’m not sure if you can use the soft bodies section for rigid body dynamics. You can write a script link that controls the motion of objects in Blender using physics equations and take into account friction etc.

I don’t think I’d do that for a ball though. I’d probably just attach it to a path curve and calculate the keyframes using a separate program - even a python program - and then attach the keyframes manually.

ok thanks
i found this python script for blender that looks helpful

Edit; the dl link doesnt work :frowning:

thanks :slight_smile:

There was talk of being able to bake game-engine physics into IPO’s in the latest version. I can’t find any info on it, though, but it’d be exactly what you’re looking for.

In 2.4, in the top header goto “Game >> Save Game Physics to IPO”.
