Java球球大作战小游戏源码(完整版)

球球大作战小游戏完整源码分享，可以当作Java入门课程设计作品

涉及知识点：文件IO流、多线程、面向对象、Java基础语法等知识

一、游戏设计思想：

（1）在一张地图上生成若干个小球以及玩家小球，有若干个地图可供选择。

（2）玩家通过移动鼠标进行移动，可停止移动，吐孢子，

（3）游戏期间通过Ranking排行榜实时更新小球排名，

（4）所有Ai小球都会想着吃掉其他小球，成为唯一的胜利者。

（5）当玩家小球被吃掉即游戏结束，但是可以通过重新开始，继续进行游戏。

（6）ai自动追逐算法 (自动追逐比自己小的球，自动躲避比自己大的球)

结尾附完整可直接运行代码百度网盘

2.1背景音乐播放代码

java 复制代码

package ballf;

import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
import java.io.File;
import java.io.IOException;
import java.net.URL;

import javax.sound.sampled.LineUnavailableException;
import javax.sound.sampled.UnsupportedAudioFileException;

public class PlayMusic {

	public static void playBackgroundMusic() {
        try {
            // 获取音频文件的URL
            URL url = PlayMusic.class.getResource("/Music/bgmusic.wav");
            // 打开音频输入流
            AudioInputStream audioIn = AudioSystem.getAudioInputStream(url);
            // 获取一个音频剪辑
            Clip clip = AudioSystem.getClip();
            // 打开剪辑并加载样本
            clip.open(audioIn);
            // 设置剪辑循环播放
            clip.loop(Clip.LOOP_CONTINUOUSLY);
        } catch (UnsupportedAudioFileException e) {
            e.printStackTrace();
        } catch (IOException e) {

2.2UI界面绘制代码

java 复制代码

public void paint(Graphics g){
    super.paint(g);
      if (this.state == 0){
      g.drawImage(this.mainui, -30, 0, (int)(windowWidth * 1.2D), (int)(windowHeight * 1.1D), null);

    }
    if (this.state == 1){

      g.setColor(Color.magenta);
      g.setFont(new Font("Comic Sans MS", 0, 90));
      g.drawString("Loading......", 500, 600);
      if (this.pause > 320){
        this.state = 2;
        this.choosemap = 0;
        for (int i = 0; i < 7; i++) {
          if (this.choosemap == i) {
            this.map[i] = Color.red;
          } else {
            this.map[i] = Color.blue;
          }
        }
      }
      else if (this.pause == 10){
        Loadbg loadbg = new Loadbg();
        new Thread(loadbg).start();
        this.pause += 1;
      }else{
        this.pause += 1;
