一、项目介绍

贪吃蛇是一款经典的休闲益智游戏,自问世以来便深受广大用户的喜爱。这个游戏的基本玩法是控制一条不断增长的蛇,目标是吃掉屏幕上出现的食物,同时避免撞到边缘或自身。随着游戏的进行,蛇的身体会越长越大,操控难度也越来越高,为玩家带来了挑战性和乐趣。

随着计算机和移动设备的普及,贪吃蛇游戏也逐渐从最初的黑白方块发展成为精美的图形游戏。但是无论视觉效果如何,游戏的核心玩法始终保持不变,这也是贪吃蛇游戏能持续吸引玩家的重要原因。

二、核心代码

启动窗口

public class StartGame {public static void main(String[] args) throws UnsupportedAudioFileException, IOException, LineUnavailableException {//音乐./*Thread t1 = new PlayMusic();t1.start();*/JFrame jf = new JFrame();jf.setTitle("贪吃蛇大作战");jf.setBounds(10,10,600,485);jf.setResizable(false);jf.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);jf.setVisible(true);//正常游戏界面放在面板上jf.add(new GamePanel());}
}

存放数据

public class DataCenter {public static URL headerURL=DataCenter.class.getResource("/Static/Header.png");public static URL upURL=DataCenter.class.getResource("/Static/Up.png");public static URL rightURL=DataCenter.class.getResource("/Static/Right.png");public static URL downURL=DataCenter.class.getResource("/Static/Down.png");public static URL leftURL=DataCenter.class.getResource("/Static/Left.png");public static URL bodyURL=DataCenter.class.getResource("/Static/Body.png");public static URL foodURL=DataCenter.class.getResource("/Static/Food.png");public static ImageIcon header=new ImageIcon(headerURL);public static ImageIcon up=new ImageIcon(upURL);public static ImageIcon right=new ImageIcon(rightURL);public static ImageIcon down=new ImageIcon(downURL);public static ImageIcon left=new ImageIcon(leftURL);public static ImageIcon body=new ImageIcon(bodyURL);public static ImageIcon food=new ImageIcon(foodURL);}

游戏初始化

 //游戏初始化public void init(){length = 3;//蛇的长度，初始为3String direction;//初始方向向右//脑袋的坐标snakeX[0] = 95;snakeY[0] = 110;//第一节身体snakeX[1] = 70;snakeY[1] = 110;//第二节身体snakeX[2] = 45;snakeY[2] = 110;direct = "R";//初始方向向右score=0;gameState = false;//默认还没开始游戏//游戏一开始定时器就启动timer.start();foodX = 20 + 25 * random.nextInt(22);//生成[0-21]的整数foodY = 85 + 25 * random.nextInt(14);//生成[0-13]的整数isFail = false;}

绘制面板

 //绘制面板@Overrideprotected void paintComponent(Graphics g) {this.setBackground(Color.WHITE);super.paintComponent(g);//清屏//绘制静态面板//头部图片DataCenter.header.paintIcon(this, g, 20, 8);//游戏面板g.fillRect(20, 85, 548, 355);//画积分g.setColor(Color.WHITE);g.setFont(new Font("微软雅黑",Font.BOLD,20));g.drawString("长度："+length,450,32);g.drawString("分数："+score,450,55);//画食物DataCenter.food.paintIcon(this, g, foodX, foodY);//画小蛇头if (direct.equals("U")) {DataCenter.up.paintIcon(this, g, snakeX[0], snakeY[0]);} else if (direct.equals("R")) {DataCenter.right.paintIcon(this, g, snakeX[0], snakeY[0]);} else if (direct.equals("D")) {DataCenter.down.paintIcon(this, g, snakeX[0], snakeY[0]);} else if (direct.equals("L")) {DataCenter.left.paintIcon(this, g, snakeX[0], snakeY[0]);}//画蛇身for (int i = 1; i < length; i++) {DataCenter.body.paintIcon(this, g, snakeX[i], snakeY[i]);}//游戏状态if (gameState == false) {g.setColor(new Color(231, 85, 18));g.setFont(new Font("微软雅黑", Font.BOLD, 40));g.drawString("按下空格开始游戏！", 126, 265);}if (isFail) {g.setColor(new Color(226, 9, 9));g.setFont(new Font("微软雅黑", Font.BOLD, 40));g.drawString("游戏失败！按下空格重新开始", 40, 265);}}
