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.)
	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 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.)

	Enabled	Gets or sets a value indicating whether this constraint is enabled. (Inherited from Constraint.)
	ErrorReduction	Gets or sets the error reduction parameter.
	LinearConstraintImpulse	Gets or sets the linear constraint impulse that was applied. (Overrides ConstraintLinearConstraintImpulse.)
	MaxForce	Gets or sets the maximal force that is applied by this constraint.
	Maximum	Gets or sets the maximum rotation limits about the two rotation axis.
	Minimum	Gets or sets the minimum rotation limits about the two rotation axis.

Remarks

A universal joint is also known as universal coupling, U joint, Cardan joint, Hardy-Spicer joint or Hooke's joint. This joint fixes all three translational degrees of movement and 1 rotational degree of movement. It allows rotations about the constraint anchor x-axis and the constraint anchor y-axis.
