Weebles wobble but they don't fall down

I don’t know if anyone remembers the old ‘weebles’ toys in the UK, but that’s what my animated bowling scene looks like. Seems like the centre of gravity for the pins is at the base somehow? No idea what I’ve done wrong!

Yes, it has come up before. The Centre of gravity needs to be the geometry center based not the origin point.

Thanks. So that’s what the bit at the start of the lesson was about? Anyway I can get it to work now, thanks

How?

Hi Roy,

Its in lecture 60, near the start - timestamp around 1:10. Its not really explained why its being done in the video, but the effect is to set the centre of gravity (i.e. the origin) to the middle of the pin. I skipped this first time through and only realised the importance later.
