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 class, HingeJoint2D class, SliderJoint2D class.

Variables

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

Functions

GetReactionForce Gets the reaction force of the joint given the specified timestep.
GetReactionTorque Gets the reaction torque of the joint given the specified timestep.

Inherited members

Variables

anchor The joint's anchor point on the object that has the joint component.
connectedAnchor The joint's anchor point on the second object (ie, the one which doesn't have the joint component).
enabled Enabled Behaviours are Updated, disabled Behaviours are not.
animation The Animation attached to this GameObject (null if there is none attached).
audio The AudioSource attached to this GameObject (null if there is none attached).
camera The Camera attached to this GameObject (null if there is none attached).
collider The Collider attached to this GameObject (null if there is none attached).
collider2D The Collider2D component attached to the object.
constantForce The ConstantForce attached to this GameObject (null if there is none attached).
gameObject The game object this component is attached to. A component is always attached to a game object.
guiText The GUIText attached to this GameObject (null if there is none attached).
guiTexture The GUITexture attached to this GameObject (Read Only). (null if there is none attached).
hingeJoint The HingeJoint attached to this GameObject (null if there is none attached).
light The Light attached to this GameObject (null if there is none attached).
networkView The NetworkView attached to this GameObject (Read Only). (null if there is none attached).
particleEmitter The ParticleEmitter attached to this GameObject (null if there is none attached).
particleSystem The ParticleSystem attached to this GameObject (null if there is none attached).
renderer The Renderer attached to this GameObject (null if there is none attached).
rigidbody The Rigidbody attached to this GameObject (null if there is none attached).
rigidbody2D The Rigidbody2D that is attached to the Component's GameObject.
tag The tag of this game object.
transform The Transform attached to this GameObject (null if there is none attached).
collideConnected Can the joint collide with the other Rigidbody2D object to which it is attached?
connectedBody The Rigidbody2D object to which the other end of the joint is attached (ie, the object without the joint component).
hideFlags Should the object be hidden, saved with the scene or modifiable by the user?
name The name of the object.

Functions

BroadcastMessage Calls the method named methodName on every MonoBehaviour in this game object or any of its children.
CompareTag Is this game object tagged with /tag/?
GetComponent Returns the component of Type type if the game object has one attached, null if it doesn't.
GetComponentInChildren Returns the component of Type type in the GameObject or any of its children using depth first search.
GetComponentInParent Returns the component of Type type in the GameObject or any of its parents.
GetComponents Returns all components of Type type in the GameObject.
GetComponentsInChildren Returns all components of Type type in the GameObject or any of its children.
GetComponentsInParent Returns all components of Type type in the GameObject or any of its parents.
SendMessage Calls the method named methodName on every MonoBehaviour in this game object.
SendMessageUpwards Calls the method named methodName on every MonoBehaviour in this game object and on every ancestor of the behaviour.
GetInstanceID Returns the instance id of the object.
ToString Returns the name of the game object.

Static Functions

Destroy Removes a gameobject, component or asset.
DestroyImmediate Destroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoad Makes the object target not be destroyed automatically when loading a new scene.
FindObjectOfType Returns the first active loaded object of Type type.
FindObjectsOfType Returns a list of all active loaded objects of Type type.
Instantiate Clones the object original and returns the clone.

Operators

bool Does the object exist?
operator != Compares if two objects refer to a different object.
operator == Compares if two objects refer to the same.
