java - Libgdx AssetsManager-声音已加载但 “Not Loaded Error”吗？

使用LibGDX的AssetsManager时，我已经实现了一个AssetsManager来管理声音，并将其设置为全局。这些文件都位于

../data/sounds/.*
(example: ../data/sounds/buttons/buttonl.mp3)

然后，我将声音文件加载到管理器中，然后包含一些代码来播放这些声音。代码如下:

public final class Sounds {
    private static HashMap<String, HashMap<String, String>> entries = new HashMap<String, HashMap<String, String>>();
    private static HashMap<String, String> currentPackage = new HashMap<String, String>();
    public static Sound sound;

    public Sounds() {
        addPath(
            "Main",
            "bgm", "data/sounds/main/title.mp3",
            "buttonl", "data/sounds/buttons/buttonl.mp3",
            "buttonh", "data/sounds/buttons/buttonh.mp3");

        //... More paths with more sound assets
    }

    public static boolean addPath(String packageName, String... args) {
        if(!entries.containsKey(packageName)) {
            entries.put(packageName, new HashMap<String, String>());
            for(int i = 0; i < args.length; i ++)
                entries.get(packageName).put(args[i], args[++i]);
            return true;
        }
        return false;
    }

    public static void loadSoundAssets(String packageName) {
        for(String str : entries.get(packageName).values())
            s_manager.load(str, Sound.class);
        s_manager.finishLoading();
    }

    public static boolean play(String file) {
        if(currentPackage.containsKey(file)) {
            sound = s_manager.get(file, Sound.class);
            sound.play();
            return true;
        }
        return false;
    }
}

在使用更高的类别创建Sound类之后

public class Game implements ApplicationListener{
    public Sounds gameSounds = new Sounds();

    public Screen currentScreen = new MainMenuScreen();
    //... More class variables and methods

    public void render() {
        currentScreen.update();
    }
}

当我打电话时问题来了

public class MainScreen() extends Screen {
    public MainScreen() {
        Sounds.loadSoundAssets("Main");
        //... More constructor variables and methods
    }
    //... Class variables and methods

    public void update() {
        if(s_manager.update()) {
            if(play.getBoundingRectangle().contains(x, y))
                Sounds.play("buttonl");
        }
    }
}

s_manager.update()返回true，但随后尝试播放声音文件“buttonl”并引发以下错误:

Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: Asset not loaded: buttonh
    at com.badlogic.gdx.assets.AssetManager.get(AssetManager.java:121)
    at device.sounds.Sounds.play(Sounds.java:146)
    at game.screens.MainMenuScreen.update(MainMenuScreen.java:63)
    at menu.StateManager.render(StateManager.java:89)
    at com.badlogic.gdx.backends.lwjgl.LwjglApplication.mainLoop(LwjglApplication.java:190)
    at com.badlogic.gdx.backends.lwjgl.LwjglApplication$1.run(LwjglApplication.java:110)

我应该如何使用AssetsManager来解决此加载/播放问题？我想使用AssetsManager，但是目前，我的解决方案是使用

sound = Gdx.audio.newSound(Gdx.files.internal(currentPackage.get(file)));

最佳答案

我相信在您的play方法中，您是在键上调用AssetManager.get，而不是在currentPackage中调用它的值。我认为正确的播放方法是:

public static boolean play(String file) {
    if(currentPackage.containsKey(file)) {
        sound = s_manager.get(currentPackage.get(file), Sound.class);
        sound.play();
        return true;
    }
    return false;
}
