有沒有辦法使用libgdx一次加載整個目錄？

Question

我正在使用libgdx制作一個Android游戲，並且正在添加聲音fx，我想知道是否有任何方法可以一次將所有聲音文件加載到目錄中，而不是一個一個地加載。

我像這樣將它們加載到資產管理器中，但似乎找不到任何方法來加載整個文件夾。

loadassets.load（“ directory / folder / filename.mp3”，Sound.class）;

就在兩天前，我編寫了一個小實用程序類來實現這一目的。 不僅用於聲音文件，還用於任何類型的資源。

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);
            }
        }
    }
}

使用它很簡單，其工作方式如下：

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