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 int1,0,0,0,1,1,1,0,0,0,0,0,0,0,0,0,1,1,0,0,1,0,0,0,1,0,0,0,0,0,0,0,1,1,1,0,0,0,1,0,0,0,0,0,0,0,0,0,0,1,0,0,0,1,0,0,1,1,0,0,0,0,0,0;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Glaobalpublic 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;public static final int HEIGHT=15;测试游戏，下落方块出现拖影在GamePanel类的paintComponent方法中增加如下代码:在填充一个与背景同色的区域g.setColor(new Color(0 xcfcfcf);g.fillRect(0,0,Global.CELL_SIZE*Global.WIDTH,Global.CELL_SIZE*Global.HEIGHT);/填充一个灰色显示区域，避免图形拖影修改此处的同时还需修改Shape的drawme方法中设置图形的颜色，以及给frame也注册监听器。图形如何避免移出边界public boolean isMoveable(Shape shape,int action)/得到图像当前的位置信息 int left=shape.getLeft();int top=shape.getTop();/根据图形的动作，得出图形最新的位置信息 switch(action)case Shape.LEFT:left-;break;case Shape.RIGHT:left+;break;case Shape.DOWN:top+;break;/依次取出图形中的每一个点，判断是否超出显示区域 for(int x=0;x4;x+)for(int y=0;y=Global.HEIGHT|left+x=Global.WIDTH)return false;return true;
