Méthodes publiques

Méthode	Description
ExclusiveUpdate ( ) : void	Performs any pre-solve iteration work that needs exclusive access to the members of the solver updateable. Usually, this is used for applying warmstarting impulses.
GetAngularJacobianA ( Vector3 &jacobian ) : void	Gets the angular jacobian entry for the first connected entity.
GetAngularJacobianB ( Vector3 &jacobian ) : void	Gets the angular jacobian entry for the second connected entity.
GetLinearJacobianA ( Vector3 &jacobian ) : void	Gets the linear jacobian entry for the first connected entity.
GetLinearJacobianB ( Vector3 &jacobian ) : void	Gets the linear jacobian entry for the second connected entity.
GetMassMatrix ( float &outputMassMatrix ) : void	Gets the mass matrix of the constraint.
SetupJointTransforms ( Vector3 worldTwistAxisA, Vector3 worldTwistAxisB ) : void	Sets up the joint transforms by automatically creating perpendicular vectors to complete the bases.
SolveIteration ( ) : float	Solves for velocity.
TwistLimit ( ) : System	Constructs a new constraint which prevents the connected entities from twisting relative to each other beyond given limits. To finish the initialization, specify the connections (ConnectionA and ConnectionB) as well as the BasisA, BasisB and the MinimumAngle and MaximumAngle. This constructor sets the constraint's IsActive property to false by default.
TwistLimit ( Entity connectionA, Entity connectionB, Vector3 axisA, Vector3 axisB, float minimumAngle, float maximumAngle ) : System	Constructs a new constraint which prevents the connected entities from twisting relative to each other beyond given limits.
Update ( float dt ) : void	Do any necessary computations to prepare the constraint for this frame.
