用到的一些全局變量

//全局變量 public class Global {public static final int RECT_WIDTH=20;//每個小方格的長寬public static final int WIDTH=30;//長 40個小方格public static final int HEIGHT=30;//寬 40個小方格public static int GRADE;//成績public static long TIME;//時間public static File file;//文件夾 }

定義蛇類

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;//表示蛇運動的方向private int newdirction=RIGHT;private int olddirction=RIGHT;private Point tail;//存儲蛇的尾巴public LinkedList<Point> body=new LinkedList<Point>();private Point p;//蛇的顏色private int x,y,z;private boolean suspendFlag = false;// 控制線程的執行private SnakeDriver sd=new SnakeDriver();public static boolean life=true;public Snake(){init();}//獲取蛇的長度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);//默認方向是向右的body.add(p);}}public void move() { // System.out.println("蛇在移動...");//去尾加頭法實現蛇移動 首先要得到蛇頭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));}//得到蛇頭位置public Point getSnakehead() {return body.getFirst();}public void eatfood() { // System.out.println("蛇正在吃食物...");//怎么吃 就是將蛇的尾巴加回來 則用變量存儲蛇的尾巴body.addLast(tail);}public void changedirction(int dirction) {this.newdirction=dirction; // System.out.println("正在改變方向...");}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("蛇正在畫出自己...");//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);}}//增加了自定義的監聽器public void addSnakeListener(SnakeListener snakeListener) {if(snakeListener!=null){this.snakeListener=snakeListener;}}public void start() { // new SnakeDriver().start();sd.start();}//得到線程對象public SnakeDriver getsd() {return sd;}//線程暫停public void suspend() {suspendFlag=true;}public class SnakeDriver extends Thread{//喚醒線程public synchronized void Rouse() {suspendFlag=false;notify();}@Overridepublic void run() {while(life){move();//每移動一次要判斷是否吃到食物和墻snakeListener.snakeMove(Snake.this);//調用外部類的當前對象try {Thread.sleep(200);} catch (InterruptedException e) {e.printStackTrace();}synchronized(this) {while(suspendFlag) {try {wait();} catch (InterruptedException e) {e.printStackTrace();}}}}}} }

定義食物類

public class Food {//定義兩變量來存儲food的位置private int x,y;public void drowMe(Graphics g) { // System.out.println("食物正在畫出自己...");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) {//怎么判斷食物被蛇吃了 判斷是否在同一位置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;}//設置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);} }

定義地圖類

public class Map {private int[][] map=new int[Global.WIDTH+2][Global.HEIGHT+2];//存儲邊框的數據位置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("正在畫出地圖...");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);} }

//定義接口用來監聽Snake是否碰撞

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

嘿嘿 新手 看視頻學的 加油2020年
應該能執行成功的
