Demo Project for 3D Joints (HingeJoint, SliderJoint etc.)
3D Joints can be a bit overwhelming. At the time of this writing some of the Joint Classes also have some issues.
So a bit of demonstration might be helpful therefore I put together a little demo project so you can watch and modify the behaviour of joints in 3D. This project was created using Godot 3.1beta3.
