Méthodes publiques

Méthode Description
AddEntity ( IBroadphaseEntity body ) : void

Add a body to the collision system. Adding a body to the world does automatically add it to the collision system.
CheckBothStaticOrInactive ( IBroadphaseEntity entity1, IBroadphaseEntity entity2 ) : bool

Checks the state of two bodies.
CheckBoundingBoxes ( IBroadphaseEntity entity1, IBroadphaseEntity entity2 ) : bool

Checks the AABB of the two rigid bodies.
CollisionSystem ( ) : System

Initializes a new instance of the CollisionSystem.
Detect ( IBroadphaseEntity entity1, IBroadphaseEntity entity2 ) : void

Checks two bodies for collisions using narrowphase.
Detect ( bool multiThreaded ) : void

Tells the collisionsystem to check all bodies for collisions. Hook into the PassedBroadphase and CollisionDetected events to get the results.
FindNearestTrianglePoint ( SoftBody sb, int id, Jitter.LinearMath.JVector &point ) : int
RaisePassedBroadphase ( IBroadphaseEntity entity1, IBroadphaseEntity entity2 ) : bool

Raises the PassedBroadphase event.
RaisePassedNarrowphase ( RigidBody body1, RigidBody body2, Jitter.LinearMath.JVector &point, Jitter.LinearMath.JVector &normal, float penetration ) : bool

Raises the PassedNarrowphase event.
Raycast ( Jitter.LinearMath.JVector rayOrigin, Jitter.LinearMath.JVector rayDirection, RaycastCallback raycast, RigidBody &body, Jitter.LinearMath.JVector &normal, float &fraction ) : bool

Sends a ray (definied by start and direction) through the scene (all bodies added). NOTE: For performance reasons terrain and trianglemeshshape aren't checked against rays (rays are of infinite length). They are checked against segments which start at rayOrigin and end in rayOrigin + rayDirection.
Raycast ( RigidBody body, Jitter.LinearMath.JVector rayOrigin, Jitter.LinearMath.JVector rayDirection, Jitter.LinearMath.JVector &normal, float &fraction ) : bool

Raycasts a single body. NOTE: For performance reasons terrain and trianglemeshshape aren't checked against rays (rays are of infinite length). They are checked against segments which start at rayOrigin and end in rayOrigin + rayDirection.
RemoveEntity ( IBroadphaseEntity body ) : bool

Remove a body from the collision system. Removing a body from the world does automatically remove it from the collision system.
