Constructor Detail

BoundingBox

public BoundingBox(int x1,
                   int y1,
                   int x2,
                   int y2)

Create a bounding box with these boundaries

Parameters:

x1 - The first x val generally describing the left of the box.

y1 - The first y val generally describing the bottom of the box.

x2 - The second x val generally describing the right of the box.

y2 - The secind y val generally describing the top of the box.

Method Detail

doesLineCrossBoundingBox

public boolean doesLineCrossBoundingBox(int x1,
                                        int y1,
                                        int x2,
                                        int y2)

Test the provided line segment for intersection with this bounding box. The parameters list two points describing a line segement such that a given line segment goes from point (x1,y1) to (x2,y2).

Returns:

true if the line intersects this bounding box, false otherwise.

getTop

public int getTop()

Get the top boundary

Returns:

The top of the box (y2)

getLeft

public int getLeft()

Get the left boundary

Returns:

The left of the box (x1)

getBottom

public int getBottom()

Get the bottom boundary

Returns:

The bottom of the box (y1)

getRight

public int getRight()

Get the right boundary

Returns:

The right of the box (x2)

debug

public void debug()
