Method Detail

getIntersection

public SpaceElement getIntersection(Ray2D ray,
                                    Vector2f location,
                                    Predicate<? super SpaceElement> filter)

Description copied from class: Space

Checks for an intersection between the provided ray and the contents of the space.

Specified by:

getIntersection in class Space

location - a vector to populate with the location of the intersection, if any.

filter - a predicate to use in filtering the results of the test.

Returns:

a reference to the first element intersected by the ray, or null for none.

getIntersecting

public void getIntersecting(Shape shape,
                            Collection<SpaceElement> results)

Description copied from class: Space

Retrieves all space elements that intersect the provided shape.

Specified by:

getIntersecting in class Space

results - a collection to hold the results of the search.

getElements

public void getElements(Rect bounds,
                        Collection<SpaceElement> results)

Description copied from class: Space

Retrieves all space elements whose bounds intersect the provided region.

Specified by:

getElements in class Space

results - a list to hold the results of the search.
