Class ColliderFactory

java.lang.Object
  net.phys2d.raw.collide.ColliderFactory

public class ColliderFactory

extends java.lang.Object

A collider factory to create colliders for arbitrary bodies, or actually their shapes. This was implemented to replace a visitor-pattern based implementation, that required many files to be edited to add a new shape. Furthermore this factory can handle singleton colliders if needed.

Method Detail

createCollider

public Collider createCollider(Body bodyA,
                               Body bodyB)
                        throws ColliderUnavailableException

Create a collider for two bodies. The decision depends on the body's shapes.

Parameters:

bodyA - First body in the collision test

bodyB - Second body in the collision test

Returns:

A collider that can test wether the two bodies actually collide

Throws:

ColliderUnavailableException - This exception will be thrown if no suitable collider can be found.

createColliderFor

public Collider createColliderFor(Circle shapeA,
                                  Shape shapeB)
                           throws ColliderUnavailableException

Creates a collider for a Circle and a Shape. The choice is based on the kind of Shape that is provided

Parameters:

shapeA - The circle to provide a collider for

shapeB - The shape to provide a collider for

Returns:

a suitable collider

Throws:

ColliderUnavailableException - This exception will be thrown if no suitable collider can be found.

createColliderFor

public Collider createColliderFor(Box shapeA,
                                  Shape shapeB)
                           throws ColliderUnavailableException

Creates a collider for a Box and a Shape. The choice is based on the kind of Shape that is provided

Parameters:

shapeA - The box to provide a collider for

shapeB - The shape to provide a collider for

Returns:

a suitable collider

Throws:

ColliderUnavailableException - This exception will be thrown if no suitable collider can be found.

createColliderFor

public Collider createColliderFor(Line shapeA,
                                  Shape shapeB)
                           throws ColliderUnavailableException

Creates a collider for a Line and a Shape. The choice is based on the kind of Shape that is provided

Parameters:

shapeA - The line to provide a collider for

shapeB - The shape to provide a collider for

Returns:

a suitable collider

Throws:

ColliderUnavailableException - This exception will be thrown if no suitable collider can be found.

createColliderFor

public Collider createColliderFor(Polygon shapeA,
                                  Shape shapeB)
                           throws ColliderUnavailableException

Creates a collider for a ConvexPolygon and a Shape. The choice is based on the kind of Shape that is provided

Parameters:

shapeA - The convex polygon to provide a collider for

shapeB - The shape to provide a collider for

Returns:

a suitable collider

Throws:

ColliderUnavailableException - This exception will be thrown if no suitable collider can be found.
