Panic time!
So I took a risk in deciding to code some “proper” physics myself insted of just fudging things and having pipes that don’t collide with anything. It seemed to work, but now I’ve let the player grab hold of one end it all goes horribly wrong. The pipes tend to get stuck on the rather angular levels so it stretches and goes wrong in all sorts of horrible ways.
Unless I can figure out a quick way to make this stable, I think I’m screwed.
