Description

Joint that attempts to keep two Rigidbody2D objects a set distance apart by applying a force between them.

Note that unlike DistanceJoint2D, the length of the joint can stretch and oscillate.

See Also: DistanceJoint2D, HingeJoint2D, SliderJoint2D.

Variables

dampingRatioThe amount by which the spring force is reduced in proportion to the movement speed.
distanceThe distance the spring will try to keep between the two objects.
frequencyThe frequency at which the spring oscillates around the distance distance between the objects.

Public Functions

GetReactionForceGets the reaction force of the joint given the specified timestep.
GetReactionTorqueGets the reaction torque of the joint given the specified timestep.

Inherited members

Variables

anchorThe joint's anchor point on the object that has the joint component.
connectedAnchorThe joint's anchor point on the second object (ie, the one which doesn't have the joint component).
enabledEnabled Behaviours are Updated, disabled Behaviours are not.
isActiveAndEnabledHas the Behaviour had enabled called.
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 (null if there is none attached).
connectedBodyThe Rigidbody2D object to which the other end of the joint is attached (ie, the object without the joint component).
enableCollisionShould rigid bodies connected with this joint collide?
hideFlagsShould the object be hidden, saved with the scene or modifiable by the user?
nameThe name of the object.

Public Functions

BroadcastMessageCalls the method named methodName on every MonoBehaviour in this game object or any of its children.
CompareTagIs this game object tagged with tag ?
GetComponentReturns the component of Type type if the game object has one attached, null if it doesn't.
GetComponentInChildrenReturns the component of Type type in the GameObject or any of its children using depth first search.
GetComponentInParentReturns the component of Type type in the GameObject or any of its parents.
GetComponentsReturns all components of Type type in the GameObject.
GetComponentsInChildrenReturns all components of Type type in the GameObject or any of its children.
GetComponentsInParentReturns all components of Type type in the GameObject or any of its parents.
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.
GetInstanceIDReturns the instance id of the object.
ToStringReturns the name of the game object.

Static Functions

DestroyRemoves a gameobject, component or asset.
DestroyImmediateDestroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoadMakes the object target not be destroyed automatically when loading a new scene.
FindObjectOfTypeReturns the first active loaded object of Type type.
FindObjectsOfTypeReturns a list of all active 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.
