我一直在关注 Buckys java 游戏开发,并使用 slick 进行游戏的基本设置,从那时起我就将它掌握在自己手中。目前我只是在构建菜单,它几乎完成了,除了我想给它添加声音。我已经坚持了一个星期,所以它不像我没有为此做过任何研究,我只是无法让它发挥作用。现在我找到了一些代码来执行此操作,这似乎很有意义,我该如何实现它,或者如果您对如何添加一些声音有更好的想法,不胜感激。
import javax.sound.sampled.AudioInputStream;
import javax.sound.sampled.AudioSystem;
import javax.sound.sampled.Clip;
static String soundtrack = "res/doxx.wav";
public void sound(String path){
try{
AudioInputStream audio = AudioSystem.getAudioInputStream(Menu.class.getResource(path));
Clip clip = AudioSystem.getClip();
clip.open(audio);
clip.start();
} catch (Exception e){
System.out.println("check "+path+"\n");
e.printStackTrace();
}
}
编辑:此代码现在已从程序中取出,但请随时根据它发布答案
这是到目前为止与添加声音相关的代码,这是我的菜单类的全部,它不是很大。老实说,您可能不需要详细查看它,它目前完全基于图形和两个正在旋转的按钮(开始和退出)。

编辑:上面的代码现在在“init()”方法中创建一个对象,该方法调用“声音”类及其方法“playBackGround()”。Sound 类的代码在下面来自 JavaNewb 的答案中给出。
编辑:此代码产生的错误如下:
java.lang.NullPointerException

最后一点,我尝试过诸如 LWJGL 库之类的东西,我无法理解它们。我也意识到我要问多少,因为我基本上是在要求有人将其编码到我的游戏中,我希望我不必这样做,但我不知道如何解决我的问题而不将其发布在这里.
PS。不是我自己没有尝试过,所以不要痛苦,说我没有努力
