We’re using VRope for simple rope simulations in our iOS game Bee Leader, so we’ve uploaded our fixes & modifications to GitHub. We’ve updated the classes to support changing gravity in a couple of ways, added support for creating a rope using a joint (instead of two bodies, which allows for better anchor points), optimised the integration step a little, and added a fix to support retina displays.
There’s a few little things we’d like to clean up and add, but it’s working nicely at the moment in-game.
