MotorJoint class
A motor joint is used to control the relative motion between two bodies. A typical usage is to control the movement of a dynamic body with respect to the ground.

Properties
- anchorA → Vector2
-
Get the anchor point on bodyA in world coordinates.
no setteroverride
- anchorB → Vector2
-
Get the anchor point on bodyB in world coordinates.
no setteroverride
- bodyA ↔ Body
-
getter/setter pairinherited
- bodyB ↔ Body
-
getter/setter pairinherited
- collideConnected → bool
-
Get collide connected. Note: modifying the collide connect flag won't work
correctly because the flag is only checked when fixture AABBs begin to
overlap.
no setterinherited
- hashCode → int
-
The hash code for this object.
no setterinherited
- isActive → bool
-
Short-cut function to determine if either body is inactive.

- localAnchorA → Vector2

finalinherited
- localAnchorB → Vector2
-
finalinherited
- renderColor → Color3i
-
Color used to render.
finalinherited
- runtimeType → Type
-
A representation of the runtime type of the object.
