Joint suspension is used to define how suspension works on a WheelJoint2D.
See Also: WheelJoint2D class.
| angle | The world angle along which the suspension will move. This provides 2D constrained motion similar to a SliderJoint2D. This is typically how suspension works in the real world. |
| dampingRatio | The amount by which the suspension spring force is reduced in proportion to the movement speed. |
| frequency | The frequency at which the suspension spring oscillates. |
