Java实现简单版贪吃蛇游戏

本文实例为大家分享了Java实现简单版贪吃蛇游戏的具体代码，供大家参考，具体内容如下

这是一个比较简洁的小游戏，主要有三个类，一个主类，一个食物类，一个贪吃蛇类。

1、首先定义主类，主类中主要用来创建窗口

public class Main {
 
 public static final int WIDTH=600;
 public static final int HEIGHT=600;
 public static void main(String[] args) {
  JFrame win =new JFrame();
  win.setVisible(true);
  win.setSize(WIDTH, HEIGHT);
  win.setDefaultCloseOperation(3);
  win.setLocationRelativeTo(null);
  
  SnakePanel panle =new SnakePanel();
  win.add(panle);
  SnakePanel.Key l = panle.new Key();
  win.addKeyListener(l);
  panle.addKeyListener(l);
  panle.run();
 }

}

2、其次是定义食物类，食物有长和宽，还有在窗口中的位置

import java.util.Random;
public class Cell {
 protected int x;
 protected int y;
 protected int width;
 protected int height;
 Random ran=new Random();
 public Cell(){
  Random ran=new Random();
  this.x=ran.nextInt(25)*15+60;
  this.y=ran.nextInt(25)*15+50;
  this.width=15;
  this.height=15;
 }
 public Cell(int x,int y){
  this();
  this.x=x;
  this.y=y;
 }
 public int getX() {
  return x;
 }
 public void setX(int x) {
  this.x = x;
 }
 public int getY() {
  return y;
 }
 public void setY(int y) {
  this.y = y;
 }
 public int getWidth() {
  return width;
 }
 public void setWidth(int width) {
  this.width = width;
 }
 public int getHeight() {
  return height;
 }
 public void setHeight(int height) {
  this.height = height;
 }
}

3、最后是蛇类

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;
import java.util.Arrays;
import java.util.Timer;
import java.util.TimerTask;
import javax.swing.JPanel;
public class SnakePanel extends JPanel {
 final int RIGHT=1;
 final int LEFT=2;
 final int UP=3;
 final int DOWN=4;
 int moved=1;
 Cell food;
 Cell[] snake;
 public SnakePanel(){
  food=new Cell();
  snake=new Cell[5];
  for(int i=0;i=10){
   speed=125;
  }else if(snake.length>=20){
   speed=60;
  }else if(snake.length>=30){
   speed=30;
  }else if(snake.length>=40){
   speed=15;                                             
  }
  timer.schedule(task, 1000, speed);
 }
 public void step(){
  for(int i=1;i510||
    snake[snake.length-1].getX()<60||
    snake[snake.length-1].getY()>500||
    snake[snake.length-1].getY()<50){
     System.exit(0);
    }
  if(snake[snake.length-1].x==food.x &&snake[snake.length-1].y==food.y){
   snake=Arrays.copyOf(snake,snake.length+1);
   snake[snake.length-1]=food;
   food=new Cell();
  } 
 }
}

至此，一个简单的贪吃蛇小游戏就完成了。
