Examples of net.phys2d.raw.SpringJoint

net.phys2d.raw.SpringJoint
A joint representing a spring. The spring can have different constants for the stretched and compressed states. It also has a maximum and minimum compression and stretch. If the spring is compressed or stretched beyond those points, the connected bodies will push or pull each other directly. @author Gideon Smeding
