RevoluteJoint class

A revolute joint constrains two bodies to share a common point while they are free to rotate about the point. The relative rotation about the shared point is the joint angle. You can limit the relative rotation with a joint limit that specifies a lower and upper angle. You can use a motor to drive the relative rotation about the shared point. A maximum motor torque is provided so that infinite forces are not generated.

inherited
getBodyA() Body
get the first body attached to this joint.
inherited
getBodyB() Body
get the second body attached to this joint. [...]
inherited
getCollideConnected() 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.
inherited
getNext() Joint
get the next joint the world joint list.
inherited
getType() JointType
get the type of the concrete joint. [...]
inherited
isActive() bool
Short-cut function to determine if either body is inactive. [...]
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
toString() String
Returns a string representation of this object.
