有没有办法使用 libgdx 一次加载整个目录？

Question

我正在使用 libgdx 制作 Android 游戏，我正在添加声音效果，我想知道是否有任何方法可以一次加载目录中的所有声音文件而不是一个减一。

我像这样将它们加载到资产管理器中，但我似乎找不到任何方法来加载整个文件夹。

loadassets.load("目录/文件夹/文件名.mp3", Sound.class);

就在两天前，我写了一个小工具类来做这件事。不仅适用于声音文件，还适用于任何类型的资源。

public class AssetFinder {

    private AssetManager assetManager;
    private FileHandleResolver resolver;

    public class AssetDescriptor {
        public String folder;
        public Class<?> assetType;

        public AssetDescriptor(String folder, Class<?> assetType) {
            this.folder = folder;
            this.assetType = assetType;
        }
    }

    private Array<AssetDescriptor> assets = new Array<AssetDescriptor>();

    public AssetFinder(AssetManager assetManager, FileHandleResolver resolver) {
        this.assetManager = assetManager;
        this.resolver = resolver;

        assets.add(new AssetDescriptor("music", Music.class));
        assets.add(new AssetDescriptor("sound", Sound.class)); // You could remove all but this one
        assets.add(new AssetDescriptor("skin", Skin.class));
        assets.add(new AssetDescriptor("texture", Texture.class));
        assets.add(new AssetDescriptor("atlas", TextureAtlas.class));
        assets.add(new AssetDescriptor("font", BitmapFont.class));
        assets.add(new AssetDescriptor("freetype", FreeTypeFontGenerator.class));
        assets.add(new AssetDescriptor("effect", ParticleEffect.class));
        assets.add(new AssetDescriptor("pixmap", Pixmap.class));
        assets.add(new AssetDescriptor("region", PolygonRegion.class));
        assets.add(new AssetDescriptor("model", Model.class));
        assets.add(new AssetDescriptor("level", TiledMap.class));
    }

    public void load() {
        for (AssetDescriptor descriptor : assets) {
            FileHandle folder = resolver.resolve("").child(descriptor.folder);
            if (!folder.exists()) {
                continue;
            }

            for (FileHandle asset : folder.list()) {
                assetManager.load(asset.path(), descriptor.assetType);
            }
        }
    }
}

使用很简单，工作原理如下：

FileHandleResolver resolver = new InternalFileHandleResolver();
AssetManager assets = new AssetManager(resolver);
AssetFinder assetFinder = new AssetFinder(assets, resolver);
assetFinder.load();
assets.finishLoading();
