这是一款Java Applet游戏。有3种游戏状态，跑步，死亡和胜利。我的问题是两部分，但我认为它们是相关的，因为它们发生在同一点上。
问题1：当您因失去所有健康而死亡时，“重新开始”按钮会显示一次。当你死在一个洞里死亡时，它一遍又一遍地填满了屏幕。当你“赢得”关卡时，它也会填满屏幕。
问题2：与问题1相同的标准，这次仅涉及声音。敌人的死亡演奏了“死亡”歌曲。 “死亡之洞”导致歌曲在第一个音符上反复出现故障，就好像它被一个循环捕获一样。胜利让胜利歌曲以同样的方式出现故障。

这是调用声音文件的Sound.java类（尽管我不认为这个特定问题需要它）
package androidGame;
import java.applet.Applet;
import java.applet.AudioClip;
public class Sound {
public static final AudioClip MAIN = Applet.newAudioClip(Sound.class.getResource("soundtrack.au"));
public static final AudioClip GUN = Applet.newAudioClip(Sound.class.getResource("gun.au"));
public static final AudioClip DIE = Applet.newAudioClip(Sound.class.getResource("death.au"));
public static final AudioClip WIN = Applet.newAudioClip(Sound.class.getResource("win.au"));
}
答案 0 :(得分：1)
答案是，游戏陷入了困境，赢得了＃34;或者通过掉进洞里去死亡＆＃34;虽然我承认它不是最优雅的解决方案，但改变下面反映的代码可以解决问题。
if (rHealth == 0) {
state = GameState.Dead;
Sound.MAIN.stop();
Sound.DIE.play();
}
if (robot.getCenterY() > 500) {
state = GameState.Dead;
robot.setCenterY(0);
robot.setCenterX(0);
Sound.MAIN.stop();
Sound.DIE.play();
}
if (score == 35) {
state = GameState.Win;
score = 40;
Sound.MAIN.stop();
Sound.WIN.play();
}
}
