Methods

	Name	Description
	ApplyImpulse	Called by the simulation to apply an impulse that satisfies the constraint. (Inherited from Constraint.)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)

	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	OnAddToSimulation	Called when this constraint is added to a simulation. (Overrides ConstraintOnAddToSimulation.)
	OnApplyImpulse	Called when the constraint impulse should be applied. (Overrides ConstraintOnApplyImpulse.)
	OnChanged	Called when properties of this constraint were changed. (Overrides ConstraintOnChanged.)
	OnRemoveFromSimulation	Called when this constraint is removed from a simulation. (Overrides ConstraintOnRemoveFromSimulation.)
	OnSetup	Called when constraint should be set-up for a new time step. (Overrides ConstraintOnSetup.)
	Setup	Called by the simulation to prepare this constraint for constraint solving for a new time step. (Inherited from Constraint.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

This joint is best understood by an example: It models the front wheel of a car. The front wheel rotates freely around one axis (rolling axis). It can also rotate about an axis that is normal to the wheel axis (steering axis). The second rotation is controlled by the steering wheel and is used to steer the car. Per convention the steering axis is the x-axis of the constraint anchors and the rolling axis is the z-axis. The steering and rolling angles can be limited with Minimum and Maximum.
