GearJoint Class

A gear joint is used to connect two joints together. Either joint can be a revolute or prismatic joint. You specify a gear ratio to bind the motions together: coordinate1 + ratio * coordinate2 = ant The ratio can be negative or positive. If one joint is a revolute joint and the other joint is a prismatic joint, then the ratio will have units of length or units of 1/length. Warning: You have to manually destroy the gear joint if jointA or jointB is destroyed.

Syntax

Copy

public class GearJoint : Joint

The GearJoint type exposes the following members.

Constructors

	Name	Description
	GearJoint	Requires two existing revolute or prismatic joints (any combination will work). The provided joints must attach a dynamic body to a static body.

Properties

	Name	Description
	BodyA	Get the first body attached to this joint. (Inherited from Joint)
	BodyB	Get the second body attached to this joint. (Inherited from Joint)
	Breakpoint	The Breakpoint simply indicates the maximum Value the JointError can be before it breaks. The default value is float.MaxValue, which means it never breaks. (Inherited from Joint)
	CollideConnected	Set this flag to true if the attached bodies should collide. (Inherited from Joint)
	JointA	The first revolute/prismatic joint attached to the gear joint.
	JointB	The second revolute/prismatic joint attached to the gear joint.
	JointType	Gets or sets the type of the joint. (Inherited from Joint)
	Ratio	The gear ratio.
	World	Get the parent World of this joint. This is null if the joint is not attached. (Inherited from Joint)
	WorldAnchorA	(Overrides JointWorldAnchorA)
	WorldAnchorB	(Overrides JointWorldAnchorB)

Methods

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetReactionForce	(Overrides JointGetReactionForce(Single))
	GetReactionTorque	(Overrides JointGetReactionTorque(Single))
	GetType	Gets the Type of the current instance. (Inherited from Object)
	IsFixedType	Return true if the joint is a fixed type. (Inherited from Joint)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	ToString	Returns a string that represents the current object. (Inherited from Object)
	WakeBodies	(Inherited from Joint)

Events

	Name	Description
	Broke	Fires when the joint is broken. (Inherited from Joint)

Fields

	Name	Description
	Enabled	Indicate if this join is enabled or not. Disabling a joint means it is still in the simulation, but inactive. (Inherited from Joint)
	Tag	Set the user data pointer. (Inherited from Joint)
