| bodyA | The first body the joint constrains. |
| bodyB | The second body the joint constrains. |
| collideConnected | Whether the shapes on the pair of bodies can come into contact. |
| drawScale | Controls the scaling of the joint drawing. Not all joints have scalable elements but those that do will use this scaling. |
| enableLimit | Enable/disable the joint angle limit. |
| enableMotor | Enable/disable the joint motor. |
| enableSpring | Enable/Disable the rotational spring. |
| enableUnpinned | Enable/Disable unpinned mode where only Body A is affected and body B and its local anchor point is ignored. Body B must still be assigned so it is typical to assign a static ground body, preferably shared/reused. |
| forceThreshold | The force threshold beyond which a joint event will be produced. |
| localAnchorA | The local anchor frame constraint relative to bodyA's origin. |
| localAnchorB | The local anchor frame constraint relative to bodyB's origin. |
| lowerAngleLimit | The lower angle limit, in degrees. |
| maxMotorTorque | The maximum torque the motor can apply, usually in newton-meters. |
| motorSpeed | The desired motor speed, usually in degrees per second. |
| springDamping | The spring damping, non-dimensional. Use 1 for critical damping. |
| springFrequency | The spring stiffness frequency, in cycles per second. |
| springTargetAngle | The spring target angle, in degrees. |
| torqueThreshold | The torque threshold beyond which a joint event will be produced. |
| tuningDamping | Controls the joint stiffness damping, non-dimensional. Use 1 for critical damping. |
| tuningFrequency | Controls the joint stiffness frequency, in cycles per second. |
| upperAngleLimit | The upper angle limit, in degrees. |
