Platform Dependant Asset Exclusion
Is there a way to exclude source files/dlls from being included in builds?
I am well aware of using #if UNITY_IOS/etc but this requires editing the source files (a pain if the problem is in an Asset Store asset since you'll lose the changes when you update), and is not possible at all for pre-compiled libraries.
I realise there is the Plugins folder, but this doesn't quite do what I want (the problematic dll is used in C# code and doesn't need to be in the Plugins folder; I think its probably a pre-compiled Mono library or something)
Context: The particular use case I have is the Facebook SDK, which works fine in iOS and Android, as well as the editor, but breaks when being converted for Windows Phone builds with the following error:
Error building Player: Exception: Error: method System.Reflection.Assembly System.Reflection.Assembly::GetAssembly(System.Type) doesn't exist in target framework. It is referenced from IFacebook.dll at Facebook.FBBuildVersionAttribute[] Facebook.FBBuildVersionAttribute::getAttributes(System.Type).
I believe this error means at least one of the library calls it uses are not supported in the Windows Phone version of Unity. Since Windows Phone isn't supported by the plugin anyway, it seems that the logical solution is to remove it from Windows Phone builds.
However, the only way I see to do this is to write a script to "PreProcess" my build/Assets folder and either delete, change the extensions of, or hide the files/folders I don't want, which is not exactly ideal... I can't imagine that having platform specific plugins breaking builds is a rare problem, but is there an easy way to do this?
In the end I went with a hacky solution that put a . in front* of any folders I wanted excluded. I just made a text file I could search for and any instance of the file would be opened and I read the supported platforms from it and show/hide the folder containing the text file.
Its really messy, and I hate it, but it works for now :/ If anyone knows a better way please do speak up!
*For windows users who are not aware, a . at the start of a folder denotes a hidden file/folder on OSX/linux systems, and the windows version of the Unity editor also supports this. For example- .gitignore
I found that putting files like that into Assets/Editor/YOURFOLDER worked for me. Here is some documentation that briefly explains it. Hopefully this helps any people in the future that face this issue.
That could work in some cases I guess... Some plugin devs "helpfully" include code that breaks on any other editor platform too, but in that case my script to move them wouldn't work anyway. At least putting them in the editor folder makes it obvious they're still there...
I think unity 5's new plugin handling might make this all moot though, but I myself am tied to 4 with my current project, hoping to make the jump in the next few weeks though!
$$anonymous$$oving the DLLs to 'Editor' folder when compiling to a specific platform works, but it is less than optimal. It is open to human mistakes (forgetfulness). In my case, I need Sqlite DLLs for android while compiling to IOS breaks the build.
Isn't there some setting to mark the folder to be compiled to a certain platform, something I can set and forget about?
For DLLs, you can just put them in Plugins/Android, Plugins/WP8, etc. You'll need to use pre-compiler directives for platforms without the dll of course.
