Unity - Scripting API: HingeJoint

Description 描述

The HingeJoint groups together 2 rigid bodies, constraining them to move like connected by a hinge.

This joint is great for, well, doors, but can also be used to model chains, etc...

The HingeJoint has a motor which can be used to make the hinge spin around the joints axis. A spring which attempts to reach for a target angle by spinning around the joints axis. And a limit which constrains the joint angle.

Properties 属性

	angle		The current angle in degrees of the joint relative to its rest position. (Read Only)
	limits		Limit of angular rotation (in degrees) on the hinge joint.
	motor		The motor will apply a force up to a maximum force to achieve the target velocity in degrees per second.
	spring		The spring attempts to reach a target angle by adding spring and damping forces.
	useLimits		Enables the joint's limits. Disabled by default.
	useMotor		Enables the joint's motor. Disabled by default.
	useSpring		Enables the joint's spring. Disabled by default.
	velocity		The angular velocity of the joint in degrees per second. (Read Only)

Inherited Members 继承成员

Properties 属性

	gameObject		The game object this component is attached to. A component is always attached to a game object.
	tag		The tag of this game object.
	transform		The Transform attached to this GameObject.
	anchor		The Position of the anchor around which the joints motion is constrained.
	autoConfigureConnectedAnchor		Should the connectedAnchor be calculated automatically?
	axis		The Direction of the axis around which the body is constrained.
	breakForce		The force that needs to be applied for this joint to break.
	breakTorque		The torque that needs to be applied for this joint to break. To be able to break, a joint must be _Locked_ or _Limited_ on the axis of rotation where the torque is being applied. This means that some joints cannot break, such as an unconstrained Configurable Joint.
	connectedAnchor		Position of the anchor relative to the connected Rigidbody.
	connectedBody		A reference to another rigidbody this joint connects to.
	connectedMassScale		The scale to apply to the inverse mass and inertia tensor of the connected body prior to solving the constraints.
	currentForce		The force applied by the solver to satisfy all constraints.
	currentTorque		The torque applied by the solver to satisfy all constraints.
	enableCollision		Enable collision between bodies connected with the joint.
	enablePreprocessing		Toggle preprocessing for this joint.
	massScale		The scale to apply to the inverse mass and inertia tensor of the body prior to solving the constraints.
	hideFlags		Should the object be hidden, saved with the Scene or modifiable by the user?
	name		The name of the object.

Public Methods 公共方法

	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.
	TryGetComponent		Gets the component of the specified type, if it exists.
	GetInstanceID		Returns the instance id of the object.
	ToString		Returns the name of the object.

Static Methods 静态方法

	Destroy		Removes a GameObject, component or asset.
	DestroyImmediate		Destroys the object obj immediately. You are strongly recommended to use Destroy instead.
	DontDestroyOnLoad		Do not destroy the target Object 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 运算符

	bool		Does 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.
