问题描述

我开始将我的 LIBGDX 应用程序移植到 IOS.我使用 libgdx 的 Xamarin studio 端口在 IOS 上运行我的应用程序.我移植成功，但应用程序无法加载 TextureAtlas File &Iphone 模拟器中的 BitmapFont 文件.

I started porting my LIBGDX appliction to IOS. I Used Xamarin studio port of libgdx to run my application on IOS. I was successful in porting but the application failed to load the TextureAtlas File & BitmapFont File in Iphone Simulator.

我尝试的代码是

   ...
    AssetManager assetManager = new AssetManager();
    assetManager.load("packer/help.txt", TextureAtlas.class);

    if (assetManager.update()) {

    }
    ...

上面的代码在桌面和安卓上运行良好，但在 Iphone Simulator 上运行时，我得到了以下日志.

The above code is running fine for me on Desktop and android but while running it on Iphone Simulator I got the following log.

我尝试将我的包扩展名从 .txt 更改为 .pack，但得到了相同的输出.

I Tried changing my pack extension from .txt to .pack but got the same output.

我无法在 Libgdx 论坛上找到解决方案.请赐教这个问题.

I wasn't able to find the solution on Libgdx forums. Please enlighten me on this problem.

推荐答案

嘿，我找到了问题.

当我们从 Xamarin Studio 运行应用程序时，它不会打包所有项目.它留下了一些文件，如文本文件、xmls 等.我们需要标记它们以将它们包含在应用程序中.将所有这些文件标记为捆绑资源.

When we make an app run from Xamarin Studio it does not pack all the items. It leaves some of the files like text files, xmls etc. We need to mark them to include them in app. Mark all these Files to be added as Bundle Resource.
