FileTextureProvider僅從「內部」加載文件

Question

我試圖加載下載的.zip包含.g3db和所有必需紋理的文件。它看起來像.g3db文件加載罰款與loadModel()方法。但正如我所見，TextureProvider方法名爲load()只能讀取Internal文件。

任何想法如何強制ModelLoader只使用Absolute路徑？

代碼加載時

加載模型

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; 
} 

錯誤紋理

Answer 1

事實證明，你可以使用AssetManager加載存儲爲內部數據文件。成功的關鍵是使用AbsoluteFileHandleResolver()。

這是我如何從應用程序中的自定義創建的文件夾加載我的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); 
}

它說，在文檔libgdx是爲Android，你需要讓你的資產，無論是作爲一個資源或資產的文件夾中。因此，如果您必須將資產置於android資產文件夾中，則強制加載器使用文件路徑沒有意義。
