FileTextureProvider仅从“内部”加载文件

Question

我试图加载下载的.zip包含.g3db和所有必需纹理的文件。它看起来像.g3db文件加载罚款与loadModel()方法。但正如我所见，TextureProvider方法名为load()只能读取Internal文件。

任何想法如何强制ModelLoader只使用Absolute路径？

代码加载时

加载模型

UBJsonReader jsonReader = new UBJsonReader(); 
G3dModelLoader modelLoader = new G3dModelLoader(jsonReader); 
model = modelLoader.loadModel(Gdx.files.absolute(modelPath)); 

FileTextureProvider load（）方法

@Override 
public Texture load (String fileName) { 
    Texture result = new Texture(Gdx.files.internal(fileName), useMipMaps); 
    result.setFilter(minFilter, magFilter); 
    result.setWrap(uWrap, vWrap); 
    return result; 
}

Answer 1

事实证明，你可以使用AssetManager加载存储为内部数据文件。成功的关键是使用AbsoluteFileHandleResolver()。

这是我如何从应用程序中的自定义创建的文件夹加载我的Model。

private Model loadModelFromFile(File file) { 
    AssetManager assets = new AssetManager(new AbsoluteFileHandleResolver()); 
    assets.load(file.getPath(), Model.class); 
    assets.finishLoading(); 
    return assets.get(file.getPath(), Model.class); 
}

它说，在文档libgdx是为Android，你需要让你的资产，无论是作为一个资源或资产的文件夹中。因此，如果您必须将资产置于android资产文件夹中，则强制加载器使用文件路径没有意义。
