Unbuild / Extract files from build

Question

Hi, unfortunately my hard drive broke down recently due to old age and files cannot be removed from it. I occasionally double my folders but I never thought the whole hard drive would go.

I did however save the build to a usb stick jumpdrive to show a friend.

Is it possible to "unbuild" the project to get my files back?
I looked inside and didn't see the folders as they were in the project.

It's not critical though since it was only for fun, with me just creating t$$anonymous$$ngs as they occured to me.

However it was 1.5 - 2 years of scripting,debugging,modeling. So it would be really nice to get it back.

Well, the Unity3D Obfuscator can unpack a webbuild file (*.unity3d). The files that gets unpacked are almost the same as in a standalone build. All your assets (models, textures, sounds, prefabs) are packed into .assets files w$$anonymous$$ch seems to be in the same format as the generic .asset files so it should be possible to just import them back into a unity project after you changed the extention to .asset. However beside the .assets files it will also unpack your mono script DLLs. From those you can recreate most of your code (almost everyt$$anonymous$$ng except coroutines) with a C# reflector like ILSpy.

That's all not officially supported by Unity so no guarantee.

I'm sorry to hear you lost all that work, but I'm afraid I don't know of any way to do t$$anonymous$$s, and w$$anonymous$$le I'm sure it's technically possible, I hope that if anyone else knows, they won't answer to tell you. My reason being, such unbuild tools would be usable by pirates and t$$anonymous$$eves looking to steal and rehost other people's web games on their own sites for profit without permission, in order to remove or disable features that people implement specifically to prevent exactly that from happening. And yes, t$$anonymous$$s does happen, constantly. I've found half a dozen sites hosting a simple GBA game I made in 48 hours for a Ludum Dare compo (#4, years ago), without bothering to ask my permission first, and that was unfinished and barely playable!

I really am sorry that you've lost a year and a half's worth of work; I've been there myself before, in many cases losing the builds along with the project files! Eventually, it taught me the importance of keeping backups. Remember t$$anonymous$$s lesson better than I did, took losing all of my project files half a dozen times before I finally started making regular backups of my work!

Well, that makes sense but I'll leave off marking it answered for awhile just in case. From what you say, my guess is that no knowledgeable guru will dare post it on unity answers for the reason you mentioned or so that unity wouldnt patch over any trick they had found. I also suspect that the any solution would be very complicated and byond the knowledge of any average user. I can script and model much better now so it shouldnt take terribly long to get back where I was. But I thought I would post the question just in the off chance.

Well, it wasn't really an answer to your question, more a commentary on it, so I wasn't - and am still not - worried about it being accepted or not. Glad you understand, and I'm sure everyone can empathize. Almost everything I did from 13 to 25 was lost when the computer I did the work on died, I was the worst about backups. Would be nice to still have a lot of that old stuff, just for nostalgia, but in every case I went on to make new, better stuff to sacrifice to the next system crash. I'm sure you'll do the same, though I hope you don't repeat the mistake as many times as I did before learning to backup regularly!

Pirates? Thieves? That's silly. If you look carefully, any program intended to be "executed", is actually intended to be extracted somehow, somewhere, by someone.

Don't want people to be able to extract your data? Don't distribute it. Don't want people to distribute your data without your consent? Sue them. Just like that.

Trying to make people access your data and at the same time prevent them from accessing it, is just nonsense.

I for one would like to see what's suddenly doubling my build size.

I wish I had more rep for a downvote. Your "commentary" was just nonsense, and I'm glad this question was answered by more logical and not to mention smarter people. :)

I know it's an old thread, but if you want the solution: http://devxdevelopment.com/UnityUnpacker . It worked for me! Just select Unity project, select the folder and you have pretty much everything. Go to the Scripts tab, and easy! Thank you DevXDeveloper lol

Video - Restore C# code from IL2CPP (arm64) - GameRecovery 10.01

Now can partially restore Unity project Now DevX-GameRecovery 10.01 - supports code recovery from games compiled using IL2CPP technology (from native code), currently ARM64 architecture (apk, ipa) is supported.

- partial function code recovery (to c#) for Android APK - IL2CPP ARM 32/64 bit mode
- partial function code recovery (to c#) for iPhone, iPad - IPA (IOS) (only if the executable file is decrypted)

How does it work: Decompilation of functions into ASM code + Metadata -> (Virtual machine + some magic) -> C# code
