PrismaticJoint Class

A prismatic joint. This joint provides one degree of freedom: translation along an axis fixed in bodyA. Relative rotation is prevented. You can use a joint limit to restrict the range of motion and a joint motor to drive the motion or to model joint friction.

Syntax

Copy

public class PrismaticJoint : Joint

The PrismaticJoint type exposes the following members.

Constructors

	Name	Description
	PrismaticJoint(Body, Body, Vector2, Vector2, Boolean)	Initializes a new instance of the PrismaticJoint class
	PrismaticJoint(Body, Body, Vector2, Vector2, Vector2, Boolean)	This requires defining a line of motion using an axis and an anchor point. The definition uses local anchor points and a local axis so that the initial configuration can violate the constraint slightly. The joint translation is zero when the local anchor points coincide in world space. Using local anchors and a local axis helps when saving and loading a game.

Properties

	Name	Description
	Axis	The axis at which the joint moves.
	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)
	JointSpeed	Get the current joint translation speed, usually in meters per second.
	JointTranslation	Get the current joint translation, usually in meters.
	JointType	Gets or sets the type of the joint. (Inherited from Joint)
	LimitEnabled	Is the joint limit enabled?
	LocalAnchorA	The local anchor point on BodyA
	LocalAnchorB	The local anchor point on BodyB
	LocalXAxis	The axis in local coordinates relative to BodyA
	LowerLimit	Get the lower joint limit, usually in meters.
	MaxMotorForce	Set the maximum motor force, usually in N.
	MotorEnabled	Is the joint motor enabled?
	MotorImpulse	Get the current motor impulse, usually in N.
	MotorSpeed	Set the motor speed, usually in meters per second.
	ReferenceAngle	The reference angle.
	UpperLimit	Get the upper joint limit, usually in meters.
	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)
	GetMotorForce	Gets the motor force.
	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)
	SetLimits	Set the joint limits, usually in meters.
	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)
