在Unity BuildPostProcessor中，您如何简单地“复制"?一个文件? [英] In Unity BuildPostProcessor, how exactly do you, simply, "copy over" one file?

问题描述

在Unity中，我只是在Assets/

in Unity I simply have a file, afile.ts, sitting in Assets/

在内置的Xcode中，我只是希望它位于项目中包含的项目文件夹中(真的，任何地方都可以).

In the built Xcode, I simply want it to be sitting in the project folder (really, anywhere is fine) included in the project.

您可以使用

    project.AddFileToBuild(g, something something something);

但是我很简单无法弄清.

(显然在Unity中完全没有记录.)

(Obviously it is totally undocumented at Unity.)

如何完成?只是一个简单的文件-实际上是将其从Assets/filename复制到Xcode项目(它将具有目标成员身份，并位于主捆绑包中.)

How is it done? Just the one simple file - actually copy it from Assets/filename to the Xcode project (and it will have target membership and be in the main bundle).

这是一个完美的Unity构建后脚本BuildPostProcessor.cs，它很棒，可以完成其他所有操作:

但是我无法复制该死的文件！怎么做?

but I cannot copy over a damned file! How to?

注意.如果您只是简单地将文件放在Unity的名称不正确的magic文件夹中:

Note. If you very simply put a file in Unity's badly-named magic folder:

实际上，它确实执行了本质量检查中正在讨论的内容.

in fact it does exactly what is under discussion in this QA.

1. Unity ..在/StreamingAssets中有一个music.mp4或mesh.txt文件
2. 构建到Xcode
3. 您将在Xcode项目中将Music.mp4或mesh.txt包含在Target中
4. 并且iOS位置将为...

iOS上的文件夹名称，无论出于何种原因变为:/Data/Raw

因此，您的底层iOS辅助代码为:

the folder name on iOS for whatever reason becomes: /Data/Raw

Thus your low-level iOS side code would be:

而不是例如:

CFURLRef imageURL = CFBundleCopyResourceURL(
  mainBundle, CFSTR("music"), CFSTR("mp4"), NULL);

您将拥有:

CFURLRef imageURL = CFBundleCopyResourceURL(
  mainBundle, CFSTR("Data/Raw/music"), CFSTR("mp4"), NULL);

那很好.但是可以肯定的是，我们可以学习如何使用似乎存在的'.AddFileToBuild`.

That works fine. But surely we can learn how to use '.AddFileToBuild` which seems to exist for the purpose.

推荐答案

FTR我确实偶然发现了一些Unity示例代码(在一个不相关的示例项目中)，这可能会有所帮助..

FTR I did stumble on to some Unity example code (in an unrelated example project) which may help ..

public class MyBuildPostprocessor
{
    // Build postprocessor. Currently only needed on:
    // - iOS: no dynamic libraries, so plugin source files have to be copied into Xcode project
    [PostProcessBuild]
    public static void OnPostprocessBuild(BuildTarget target, string pathToBuiltProject)
    {
        if (target == BuildTarget.iOS)
            OnPostprocessBuildIOS(pathToBuiltProject);
    }

    private static void OnPostprocessBuildIOS(string pathToBuiltProject)
    {
        // We use UnityEditor.iOS.Xcode API which only exists in iOS editor module
        #if UNITY_IOS

        string projPath = pathToBuiltProject + "/Unity-iPhone.xcodeproj/project.pbxproj";

        UnityEditor.iOS.Xcode.PBXProject proj = new UnityEditor.iOS.Xcode.PBXProject();
        proj.ReadFromString(File.ReadAllText(projPath));
        string target = proj.TargetGuidByName("Unity-iPhone");

        Directory.CreateDirectory(Path.Combine(pathToBuiltProject, "Libraries/Unity"));

        string[] filesToCopy = new string[]
        {
            "PlatformBase.h",
            "RenderAPI_Metal.mm",
            "RenderAPI_OpenGLCoreES.cpp",
            "RenderAPI.cpp",
            "RenderAPI.h",
            "RenderingPlugin.cpp",
        };

        for(int i = 0 ; i < filesToCopy.Length ; ++i)
        {
            var srcPath = Path.Combine("../PluginSource/source", filesToCopy[i]);
            var dstLocalPath = "Libraries/" + filesToCopy[i];
            var dstPath = Path.Combine(pathToBuiltProject, dstLocalPath);
            File.Copy(srcPath, dstPath, true);
            proj.AddFileToBuild(target, proj.AddFile(dstLocalPath, dstLocalPath));
        }

        File.WriteAllText(projPath, proj.WriteToString());
        #endif // #if UNITY_IOS
    }
}
