public void moveLeft() System.out.println(“shapes moveLeft“); public void moveRight() System.out.println(“shapes moveright“); public void moveDown() System.out.println(“shapes moveDown“); public void rotate() System.out.println(“shapes rotate“); public void drawMe() System.out.println(“shapes drawme“); ,private class ShapeDriver implements Runnable public void run() / TODO Auto-generated method stub while(true) moveDown(); /listener.shapeMoveDown(Shape.this); try Thread.sleep(1000); catch (InterruptedException e) / TODO Auto-generated catch block e.printStackTrace();,编写各个类主体框架-ShapeFactory类,public class ShapeFactory public Shape getShape(ShapeListener listener) System.out.println(“ShapeFactorys getShape“); Shape shape=new Shape(); return shape; ,编写各个类主体框架-Ground类,package cn.tetris.entities; public class Ground public void accept() System.out.println(“Grounds accept“); public void drawMe() System.out.println(“Grounds drawMe“); ,编写各个类主体框架-GamePanel类,public class GamePanel extends JPanel private Ground ground; private Shape shape; public void display(Ground ground,Shape shape) System.out.println(“GamePanels display“); this.ground=ground; this.shape=shape; this.repaint(); Override protected void paintComponent(Graphics arg0) / TODO Auto-generated method stub /重新显示 if (ground!=null ,编写各个类主体框架-Controller类,public class Controller extends KeyAdapter private Ground ground; private Shape shape; private ShapeFactory shapeFactory; private GamePanel gamePanel; public void keyPressed(KeyEvent e) switch(e.getKeyCode() case KeyEvent.VK_UP: shape.rotate(); break; case KeyEvent.VK_LEFT: shape.moveLeft(); break; case KeyEvent.VK_RIGHT: shape.moveRight(); break; case KeyEvent.VK_DOWN: shape.moveDown(); break; gamePanel.display(ground, shape); ,编写各个类主体框架-ShapeListener接口,public interface ShapeListener void shapeMoveDown(Shape shape); ,Shape类增加监听器对象及下落后调用,public class Shape private ShapeListener listener; public void moveLeft() System.out.println(“shapes moveLeft“); public void moveRight() System.out.println(“shapes moveright“); public void moveDown() System.out.println(“shapes moveDown“); public void rotate() System.out.println(“shapes rotate“); public void drawMe() System.out.println(“shapes drawme“); ,private class ShapeDriver implements Runnable public void run() / TODO Auto-generated method stub while(true) moveDown(); listener.shapeMoveDown(Shape.this); try Thread.sleep(1000); catch (InterruptedException e) / TODO Auto-generated catch block e.printStackTrace();,Shape类中增加注册监听器的方法,public void addShapeListener(ShapeListener l) if(l!=null) this.listener =l; ,Shape构造方法中启动下落线程,public Shape() new Thread(new ShapeDriver().start(); ,Controller类实现ShapeListener接口,public class Controller extends KeyAdapter implements ShapeListener public void shapeMoveDown(Shape shape) / TODO Auto-generated method stub gamePanel.display(ground, shape); ,生产图形时同时注册监听器,public class ShapeFactory public Shape getShape(ShapeListener listener) System.out.println(“ShapeFactorys getShape“); Shape shape=new Shape(); shape.addShapeListener(listener); return shape; ,GamePanel类设置大小,public GamePanel() this.setSize(300,300); ,Controller类中增加开始新游戏方法,public void newGame() shape=shapeFactory.getShape(this); ,Controller类中如何接收外部控制的对象,public Controller(ShapeFactory shapeFactory,Ground ground, GamePanel gamePanel) this.shapeFactory=shapeFactory; this.ground=ground; this.gamePanel=gamePanel; ,测试类Game,public class Game public static void main(String args) / TODO Auto-generated method stub ShapeFactory shapeFactory=new ShapeFactory(); Ground ground=new Ground(); GamePanel gamePanel=new GamePanel(); Controller controller=new Controller(shapeFactory,ground,gamePanel); JFrame frame=new JFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(gamePanel.getSize().width+10, gamePanel.getSize().height+35); frame.add(gamePanel); gamePanel.addKeyListener(controller); frame.setVisible(true); controller.newGame(); ,程序步骤,游戏01_功能演示与说明 游戏02_面向对象设计 游戏03_使用API类组装游戏 游戏04_编写各个类主体框架 游戏05_编写Controler类实现事件监听 游戏06_编写类测试代码 游戏07_图形设计与创建 游戏08_图形移动与显示 游戏09_处理游戏边界问题 游戏10_障碍物生成与显示 游戏11_消除满行的障碍物 游戏12_增加游戏结束 游戏13_定时下落,Shape类，增加图形的描述,/二维变量用于保存图形的所有状态 private int body; /用于保存图形当前的状态 private int status; /设置状态的方法 public void setBody(int body) this.body=body; /设置当前是第几种状态 public void setStatus(int status) this.status=status; ,ShapeFactory类增加生产各种图形,/三维数组用于表示一种图形的多种形状 private int shapes=new int 1,0,0,0, 1,1,1,0, 0,0,0,0, 0,0,0,0, 1,1,0,0, 1,0,0,0, 1,0,0,0, 0,0,0,0, 1,1,1,0, 0,0,1,0, 0,0,0,0, 0,0,0,0, 0,1,0,0, 0,1,0,0, 1,1,0,0, 0,0,0,0 ;,public Shape /生产一个随机数，用于表示图形的状态 int type=new Random().nextInt(shapes.length); /设置图形有几种状态 shape.setBody(shapestype); /设置默认状态 shape.setStatus(0); return shape; ,Shape类中增加图形的位置信息,/表示图形距离左侧的距离 private int left; /表示图形距离上边界的距离 private int top; public void moveLeft() left-; public void moveRight() left+; public void moveDown() top+; public void rotate() /显示下一个状态，但得保证状态值不超过4，所以需处理 status=(status+1)%body.length; ,Shape类中增加图形的绘制方法,public void drawMe(Graphics g) System.out.println(“shapes drawme“); g.setColor(Color.RED); /循环访问代表方正的数组 for(int x=0;x4;x+) for(int y=0;y4;y+) if(getFlagByPoint(x,y) g.fill3DRect(left+x)*Global.CELL_SIZE, (top+y)*Global.CELL_SIZE, Global.CELL_SIZE, Global.CELL_SIZE, true); /获取方正中标志是1还是0，1表示要绘图0表示不绘图 private boolean getFlagByPoint(int x,int y) return bodystatusy*4+x=1; ,游戏常量的存放Glaobal,public class Global /表示每个方格的像素值 public static final int CELL_SIZE=20; /表示图形面板有多少个格子宽和高 public static final int WIDTH=15; pu
