set

public BoundingBox set(double minX,
                       double minY,
                       double maxX,
                       double maxY)

add

public BoundingBox add(double x,
                       double y)

expand

public BoundingBox expand(double x,
                          double y)

expand

public BoundingBox expand(double amount)

intersects

public boolean intersects(BoundingBox other)

intersects

public boolean intersects(double minX,
                          double minY,

isEmpty

public boolean isEmpty()

getBoundEdge

public double getBoundEdge(Direction direction)

Gets the position of an edge based on the direction. For example: box = BoundBox(-2.8, 0.2, 10.2, 11.5) box.getBoundEdge(Direction.UP) is 11.5. box.getBoundEdge(Direction.LEFT) is -2.8.

Parameters:

direction - The (CARDINAL) direction towards the edge

Returns:

The position value at that edge if direction is cardinal, 0 otherwise.
