I'm amazed at how easily I could implement this. Yes it took some setting up and yes I got caught up in fixing and refactoring some stuff, but even though it took a while, the actual implementation for this was pretty straightforward.

Unfortunately SFML does not have a possibility to render bezier curves, so I'm not showing the rope being loose. Instead I've made it look like the rope length is constantly adjusted automatically to keep tension on the rope.

Anyway, here's the result!

I'll probably be pretty quiet for a few weeks. My wife and I are waiting these last few days for our daughter to be born.
