Unity uses FlasCC-like fast memory opcodes while converting C++ to AS3 (very conversions rich process), so you'll not get clean as3 code after decompilation anyway.

You'll be able to see the original user code in somewhat clean state though (converted from C# or JS to as3) and it's not so huge in size as Unity3D engine usually. Just look at the global namespace. You don't need to decompile while Unity3D engine to see the user code.

Oops, sorry. FFDec doesn't see the global namespace. As well as many other as3 code there =(

what I want is get the unityNative.as and add an line code to implement "sharecontext" property which Unity team did not provide.

You can do the following: (- increase the memory limit in ffdec.bat or use ffdec64.bat) - Open your swf - In settings menu select Disable decompilation (Disassemble only) - Open UnityNative script - It loads after 1-2 minutes - Find your function, put the mouse cursor inside the function - You can see the decompiled instructions in the right textarea - Press Edit button in the right panel, and modify your function's AVM2 insructions It is unnecessary to decompile the whole class to AS, because you can't edit AS3 directly anyway. Is this solve your problem?
