Haha oh, I just realized you’re probably referring to the Advanced Character Physics article — yes, very helpful!

Glad it was of use, Hannes. I really do need to revisit this stuff some day …

It is a very helpful article, it helped with my ragdoll project a lot.

An easy way to think of verlet is that it takes the current position Vector (x), then moves it by as much as it moved in the last frame(x – oldx), and then adds acceleration (a), put this all together and you get x + (x-oldx) + a, or 2x – oldx + a

No worries OJ, my nerdy Python brain is yours for the picking.

And yes, the article is fantastic. It’s slow going for somebody who sucks at mathematics as much as I do, but it’s great fun trying to put it into practice all the same.

Next on the agenda is collision detection & proper constraint handling …

This stuff looks like fun. I’m going to start ramping up with a bit of Python work, so you might have a few questions coming your way.

That character physics article looks like a good read too. Will check that out a bit later
Cheers!
