public class Board
This public class is the surface on which an Eggtris game is played. The use it you must do the following:
(1) Construct one (see below)
(2) Set an active Shape
(3) Check for lines and when some are found do what you want
(4) If a Shape cannot move down, tell it to giveItsBricksTo this Board
(5) repeat......

This is used by Brick to see if it can move to this spot |
void |
paint(java.awt.Graphics g)
Paints the Graphics context passed in by first painting the back-drop (at the moment, that is just a colored background. |
void |
putBrick(Brick brick,
int x,

Constructor Detail |

public Board(int x, int y, int width, int height, int brickSize)
width
- Number of bricks across.height
- Number of bricks tall.brickSize
- The size of the bricks that are created. This is
needed by both Brick and Shape.x
- X position.y
- Y position.Method Detail |
---|
public void paint(java.awt.Graphics g)
paint
in class java.awt.Canvas
g
- Graphics context on which to paint.public boolean hasAnEmptySpotIn(int x, int y)
x
- The possible s spot.y
- The possible y spot.
public void putBrick(Brick brick, int x, int y)
brick
- Brick to put on.x
- Array spot x in which to put it.y
- Array spot y in which to put it.public void setActiveShape(MyShape newActiveShape)
This MUST be called by the Applet (or whatever the controller is) after a Shape is set. After the Shape giveItsBricks to this, the Applet must call this method so the board can treat the new Shape specially.
newActiveShape
- Shape which becomes the new active Shape.#eggtris.Shape
public void clearRow(int row)
Nullifies the row passed in, if it is within the range of rows.
Called by checkForLines.
row
- Row to clear.#eggtris.Board.checkForLines()
public void dropRows(int bottomMostRow, int numberOfRows)
Drops all the rows by numberofRows, starting at bottomMostRow.
bottomMostRow
- The furthest row down from which to start the drop.numberOfRows
- Number of rows to drop.#eggtris.Board.checkForLines()
public int checkForLines()
