Method Detail

getCombinedBoundBox

public static BoundBox getCombinedBoundBox(java.util.List<BoundBox> boxes)

set

public BoundBox set(BoundBox box)

set

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

add

public BoundBox add(double x,
                    double y)

expand

public BoundBox expand(double x,
                       double y)

expand

public BoundBox expand(double amount)

intersects

public boolean intersects(BoundBox other)

intersects

public boolean intersects(double minX,
                          double minY,
                          double maxX,

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.
