I then tried a Hinge Joint 2D and got even worst effects. 1a, whose theory is based on the same concept of the original post with intensive use of revolute joints. But when too much pressure (or weight) is put on the "bridge" the revolute joints flex to a point where the object passes through. But I did not get any leads. 1. Feb 8, 2012 В· I use distance and rope Joints, set different values of parameters dampingRatio and frequencyHz, but the effect is far from being an example (my thread for a long time coming to original state, and not so elastic. A "simpler" solution using box2d would be to "emulate" the variation of length by hiding some of the rope (with fixed length) outside the visible world / not drawing some of the rope. The examples were written as part of the Box2D QML plugin and were modified to work with Felgo. A rope joint enforces a maximum distance between two points on two bodies. After figuring out a combination of revolute and prismatic joints is the best solution, I also wanted to make a ninja rope like in Worms games, where you can move up/down the rope, stand on the rope like it is a pole and the rope wraps around the terrain.
