Detailed Description

Distance joint definition.

This requires defining an anchor point on both bodies and the non-zero length of the distance joint. The definition uses local anchor points so that the initial configuration can violate the constraint slightly. This helps when saving and loading a game.

Warning:

Do not use a zero or short length.
