这是一个Java Applet游戏。共有3种游戏状态，即“跑步”，“死亡”和“胜利”。我的问题分为两部分，但我认为它们是相关的，因为它们发生在同一时间。
问题1:当您因失去全部健康而死亡时，“重新开始”按钮将显示一次。当您因掉进一个洞而死亡时，它会一遍又一遍地填满屏幕。当您“赢得”关卡时，它也会填满屏幕。
问题2:与问题1的标准相同，只是这次有关声音。被敌人的死亡播放“死亡”歌曲。孔洞死亡导致歌曲在第一音符上一遍又一遍地出现故障，好像它陷入了循环之中。获胜使获胜歌曲以相同的方式出现故障。

这是调用声音文件的Sound.java类(尽管我认为此特定问题不需要它)
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"));
}
最佳答案
答案是，游戏在“获胜”或“因掉进洞而死亡”的循环中陷入困境。尽管我承认这不是最优雅的解决方案，但是更改下面显示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();
}
}
关于java - 在一种类型的死亡(但不是另一种)上发生故障并在Java applet游戏中获胜，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/30042252/
