The limits defined by the CharacterJoint.
| bounciness | When the joint hits the limit, it can be made to bounce off it. |
| contactDistance | Distance inside the limit value at which the limit will be considered to be active by the solver. Setting this low can cause jittering, but runs fast. Setting high can deduce jittering, but runs the solver more often. (0 = use defaults) |
| limit | The limit position/angle of the joint. |
