用到的一些全局变量

//全局变量
public class Global {public static final int RECT_WIDTH=20;//每个小方格的长宽public static final int WIDTH=30;//长    40个小方格public static final int HEIGHT=30;//宽   40个小方格public static int GRADE;//成绩public static long TIME;//时间public static File file;//文件夹
}

定义蛇类

public class Snake {private SnakeListener snakeListener;public static final int UP=1;public static final int DOWN=-1;public static final int LEFT=2;public static final int RIGHT=-2;//表示蛇运动的方向private int newdirction=RIGHT;private int olddirction=RIGHT;private Point tail;//存储蛇的尾巴public LinkedList<Point> body=new LinkedList<Point>();private Point p;//蛇的颜色private int x,y,z;private boolean suspendFlag = false;// 控制线程的执行private SnakeDriver sd=new SnakeDriver();public static boolean life=true;public Snake(){init();}//获取蛇的长度public int getlenght() {return body.size();}public void init() {int x=Global.WIDTH/2;int y=Global.HEIGHT/2;for(int i=0;i<3;i++) {p=new Point(x-i,y);//默认方向是向右的body.add(p);}}public void move() {
//		System.out.println("蛇在移动...");//去尾加头法实现蛇移动  首先要得到蛇头tail=body.removeLast();int x=getSnakehead().x;int y=getSnakehead().y;if(this.newdirction+this.olddirction!=0)this.olddirction=this.newdirction;    //控制方向不往反方向行走switch(olddirction) {case UP:y--;break;case DOWN:y++;break;case LEFT:x--;break;case RIGHT:x++;break;}body.addFirst(new Point(x,y));}//得到蛇头位置public Point getSnakehead() {return body.getFirst();}public void eatfood() {
//		System.out.println("蛇正在吃食物...");//怎么吃  就是将蛇的尾巴加回来  则用变量存储蛇的尾巴body.addLast(tail);}public void changedirction(int dirction) {this.newdirction=dirction;
//		System.out.println("正在改变方向...");}public boolean iseatself(Snake snake) {Point head=snake.getSnakehead();for(int i=1;i<body.size();i++){if(body.get(i).equals(head))return true;}return false;}public void drowMe(Graphics g) {
//		System.out.println("蛇正在画出自己...");//g.setColor(Color.blue);for(int i=0;i<body.size();i++) {x=(int) (Math.random()*256);y=(int) (Math.random()*256);z=(int) (Math.random()*256);Color color=new Color(x,y,z);g.setColor(color);g.fillRect(body.get(i).x*Global.RECT_WIDTH, body.get(i).y*Global.RECT_WIDTH, Global.RECT_WIDTH, Global.RECT_WIDTH);}}//增加了自定义的监听器public void addSnakeListener(SnakeListener snakeListener) {if(snakeListener!=null){this.snakeListener=snakeListener;}}public void start() {
//		new SnakeDriver().start();sd.start();}//得到线程对象public SnakeDriver getsd() {return sd;}//线程暂停public void suspend() {suspendFlag=true;}public class SnakeDriver extends Thread{//唤醒线程public synchronized void Rouse() {suspendFlag=false;notify();}@Overridepublic void run() {while(life){move();//每移动一次要判断是否吃到食物和墙snakeListener.snakeMove(Snake.this);//调用外部类的当前对象try {Thread.sleep(200);} catch (InterruptedException e) {e.printStackTrace();}synchronized(this) {while(suspendFlag) {try {wait();} catch (InterruptedException e) {e.printStackTrace();}}}}}}
}

定义食物类

public class Food {//定义两变量来存储food的位置private int x,y;public void drowMe(Graphics g) {
//		System.out.println("食物正在画出自己...");g.setColor(Color.red);g.fillRect(x*Global.RECT_WIDTH,y*Global.RECT_WIDTH, Global.RECT_WIDTH,Global.RECT_WIDTH);}public boolean iseatbysnake(Snake snake) {//怎么判断食物被蛇吃了  判断是否在同一位置Point head=snake.getSnakehead();Point p=new Point(x,y);if(p.equals(head))return true;return false;}//增加食物public void addFood(Point p) {x=p.x;y=p.y;}//设置food的位置public Point setloction() {int x=(int)(Math.random()*30)+1;int y=(int)(Math.random()*30)+1;return new Point(x,y);}
}

定义地图类

public class Map {private int[][] map=new int[Global.WIDTH+2][Global.HEIGHT+2];//存储边框的数据位置public Map() {for(int y=0;y<Global.HEIGHT+2;y++){for(int x=0;x<Global.WIDTH+2;x++){if(y==0||y==Global.HEIGHT+2-1)map[x][y]=1;if(x==0||x==Global.WIDTH+2-1)map[x][y]=1;}}}public void drowMe(Graphics g) {
//		System.out.println("正在画出地图...");SetRectangle(g);}public boolean iseatbysnake(Snake snake) {Point head=snake.getSnakehead();for(int k=0;k<Global.WIDTH+2;k++) {for(int m=0;m<Global.HEIGHT+2;m++) {if(map[k][m]==1&&head.x==k&&head.y==m)return true;}}return false;}private void SetRectangle(Graphics g){Graphics2D gp=(Graphics2D)g;Rectangle2D rect=new Rectangle2D.Double(20, 20, 600, 600);Stroke s=new BasicStroke(5);gp.setStroke(s);gp.draw(rect);}
}

//定义接口用来监听Snake是否碰撞

public interface SnakeListener {public void snakeMove(Snake snake);
}

GUI显示

}

控制游戏

public class Controller extends KeyAdapter implements SnakeListener{private Snake snake;private Food food;private Map map;private GamePanel gamepanel;public static long starttime;//开始游戏时间public Controller(Snake snake, Food food, Map map, GamePanel gamepanel) {super();this.snake = snake;this.food = food;this.map = map;this.gamepanel = gamepanel;}@Overridepublic void keyPressed(KeyEvent e) {super.keyPressed(e);
