* **Weld (physics.JOINT_TYPE_WELD)** - A weld joint attempts to constrain all relative movement between two collision objects. The weld joint can be made soft like a spring with a frequency and damping ratio. In Box2D referred to as a Weld joint.
|
|
|
* **Spring (physics.JOINT_TYPE_SPRING)** - A spring joint keeps two collision objects at a constant distance from each other. The spring joint can be made soft like a spring with a frequency and damping ratio. In Box2D referred to as a Distance joint.
|
|
|
* **Slider (physics.JOINT_TYPE_SLIDER)** - A slider joint allows for relative translation of two collision objects along a specified axis and prevents relative rotation. In Box2D referred to as a Prismatic joint.
|
|
|
+* **Wheel (physics.JOINT_TYPE_WHEEL)** - A wheel joint restricts a point on bodyB to a line on bodyA. The wheel joint also provides a suspension spring. In Box2D referred to as a Weld joint.
