Description

Keeps two Rigidbody2D at their relative orientations.

Two Rigidbody2D connected together with this joint will have forces applied to them to keep them both at their relative linear and angular offsets. If the joint is not connected to another Rigidbody2D then the body with the joint will stay at its current linear and angular offset in world-space i.e. it will be anchored to the implicit static ground-body.

You control the maximum linear force applied to maintain the linearOffset by using maxForce.

You control the maximum torque applied to maintain the angularOffset by using maxTorque

Additional resources: linearOffset, angularOffset, maxForce, maxTorque.

Properties

angularOffsetThe current angular offset between the Rigidbody2D that the joint connects.
autoConfigureOffsetShould both the linearOffset and angularOffset be calculated automatically?
correctionScaleScales both the linear and angular forces used to correct the required relative orientation.
linearOffsetThe current linear offset between the Rigidbody2D that the joint connects.
maxForceThe maximum force that can be generated when trying to maintain the relative joint constraint.
maxTorqueThe maximum torque that can be generated when trying to maintain the relative joint constraint.
targetThe world-space position that is currently trying to be maintained.

Properties

enabledEnabled Behaviours are Updated, disabled Behaviours are not.
isActiveAndEnabledReports whether a GameObject and its associated Behaviour is active and enabled.
gameObjectThe game object this component is attached to. A component is always attached to a game object.
tagThe tag of this game object.
transformThe Transform attached to this GameObject.
attachedRigidbodyThe Rigidbody2D attached to the Joint2D.
breakActionThe action to take when the joint breaks the breakForce or breakTorque.
breakForceThe force that needs to be applied for this joint to break.
breakTorqueThe torque that needs to be applied for this joint to break.
connectedBodyThe Rigidbody2D object to which the other end of the joint is attached (ie, the object without the joint component).
enableCollisionShould the two rigid bodies connected with this joint collide with each other?
reactionForceGets the reaction force of the joint.
reactionTorqueGets the reaction torque of the joint.
hideFlagsShould the object be hidden, saved with the Scene or modifiable by the user?
nameThe name of the object.

Public Methods

BroadcastMessageCalls the method named methodName on every MonoBehaviour in this game object or any of its children.
CompareTagChecks the GameObject's tag against the defined tag.
GetComponentGets a reference to a component of type T on the same GameObject as the component specified.
GetComponentInChildrenGets a reference to a component of type T on the same GameObject as the component specified, or any child of the GameObject.
GetComponentInParentGets a reference to a component of type T on the same GameObject as the component specified, or any parent of the GameObject.
GetComponentsGets references to all components of type T on the same GameObject as the component specified.
GetComponentsInChildrenGets references to all components of type T on the same GameObject as the component specified, and any child of the GameObject.
GetComponentsInParentGets references to all components of type T on the same GameObject as the component specified, and any parent of the GameObject.
SendMessageCalls the method named methodName on every MonoBehaviour in this game object.
SendMessageUpwardsCalls the method named methodName on every MonoBehaviour in this game object and on every ancestor of the behaviour.
TryGetComponentGets the component of the specified type, if it exists.
GetReactionForceGets the reaction force of the joint given the specified timeStep.
GetReactionTorqueGets the reaction torque of the joint given the specified timeStep.
GetInstanceIDGets the instance ID of the object.
ToStringReturns the name of the object.

Static Methods

DestroyRemoves a GameObject, component or asset.
DestroyImmediateDestroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoadDo not destroy the target Object when loading a new Scene.
FindAnyObjectByTypeRetrieves any active loaded object of Type type.
FindFirstObjectByTypeRetrieves the first active loaded object of Type type.
FindObjectOfTypeReturns the first active loaded object of Type type.
FindObjectsByTypeRetrieves a list of all loaded objects of Type type.
FindObjectsOfTypeGets a list of all loaded objects of Type type.
InstantiateClones the object original and returns the clone.

Operators

boolDoes the object exist?
operator !=Compares if two objects refer to a different object.
operator ==Compares two object references to see if they refer to the same object.

Messages

OnJointBreak2DCalled when a Joint2D attached to the same game object breaks.
