As a first step towards issue #172. I don’t think this is really good enough to include as-is, but it appears to works and there's some design decisions needed that you should probably make on how to capture / structure the data and how to support LZ4.

The headlines for UnityFS are:

• most lengths and offsets are now 64-bit
• the data header is compressed with another scheme, LZ4
• there’s lots of new data I don't yet understand – not all stored and output on ‘info’ – and some old fields no longer populated
• I haven’t implemented packing, and I don’t have examples to test all code paths here.

For now I have shoe-horned the data into the existing structures, except I've added a new BundleInfoEntryFS since they are serialised differently. Might be worth considering whether to stick to a single set of structures or separate out new UnityFS classes?

To decompress LZ4 I have imported a subset of lz4-java, the native Java known-decompressed-size version. I did that rather than add a dependency because the original is likely overkill (a 200K jar, including optimised JNI versions for multiple platforms) and we’re only decompressing the data header with this. But that may be the correct solution long-term.

How difficult do you think it would be to also extract mesh assets? I'm going to have a stab at it myself, but I'm not all that familiar with how Unity handles these internally. I'm thinking if I can save out the mesh data in Unity's native format, I should be able to add them to a scene and use an editor script to export an Obj or similar?

I'm doing research on recreating golden cards from Hearthstone. I extracted some of the shaders Blizzard used to draw those cards, but it's in assembly, and there're some parts in random string, probably a type error.

Is there a way to use those shaders?

I was going to submit this as a PR, but that might mess with your existing development setup... also this probably falls under "suggestions". Adding something like https://www.gitignore.io/api/java,maven,eclipse,netbeans,jetbrains,vim to your .gitignore would help anyone else who may want to contribute. Also, removing IDE-sentric config like nbproject and build.xml makes things a little cleaner.

I wrote this under the assumption that this is meant to be a maven build/project.

Hi, I'm getting the above warning on some assets. Also (and I believe it is because of the above) the sum of the extracted files sizes is way lower than the size of the asset file (resources.assets is 46mb, extracted content is only 26mb, plus to that that also I have a resources.assets.resS of 13mb).

What info might you need to help debug the issue?

Hey, Im not a very good guy on those java compiling thing, and there is no help to compile this, but I want to use it along with Unity5 (I only need the shaders :joy:).. Is there a chance that you could bring it up to the releases tab or send me a compiled version of it? Thanks!

Hi, First of all, thank you so much for you tool. It's the only decompiler working at the moment !

I succeed to decompile a .unity3d with the latest 0.31 release. But it seems that the UV mapping is failing, do you maybe already know this issue ?

Thank you for your help ! regards, Anthony

Attempting to extract a spectific Asset file doesn't seem to work for large(? ~4+ MB) files:

1. Extract = files do not exist
2. Extract-raw = the large files are extracted as 44 bytes
3. Extract-txt = the large files are properly extracted

I also attempted to extract it using "Asset Explorer": http://forum.xentax.com/viewtopic.php?f=10&t=10085 But the files show as completely blank and I get an error called " " is not a valid integer value"

Also to clarify that this file isn't corrupt, did a file integrity check from steam (Is a steam game) and the files are music files that play just fine in the game. Extracting it as txt obviously means I cannot play the music files.

Asset file in question: https://mega.co.nz/#!aRAxjbwJ!mczwZY3JmpwnUSQ7Xxl1C6ome87WGdSFkMS9WQI8JPc

Files not extracting properly: (Extract-txt and raw names of the files)

000112 000125 000132 000153 000163 000168 000206 000232 000235 000236 000241 000260

Edit: At least the .txt files seem to be proper because of the sizes, but there doesn't seem to be a single bit that's set to 1 after the first few?

Using the default Amazon Linux build, I get the following error when attempting to start the jar. Have you got this to run in ec2?

Hi, Thank you so much for maintaining disunity ! I have a question regarding splitted assets in a game. I get some files like this : sharedassets1.assets.split0, split1, split2 etc...

I tried to list them after the "extract" argument, or unpack them with winrar. But it's not working. Do you have any solution for this case ? I join the assets here : https://mega.co.nz/#!BY8k3LjB!VeipXOsN2QM3jRkroKk9NeNPf3MVihxNrFdxPuJBk_k

Thank you so much for your help ! best regards, Anthony

Hi, i actually following a guide on Reddit to extract the sound files from Hearthstone (https://redd.it/1x0m8d). I did exactly what i have to do, but i can't apply the steps 6 and 7, which are : Run the following command: disunity.bat extract "c:\program files (x86)\hearthstone\data\win\sounds0.unity3d". In my case, the files are in D:\ so i just replace the letter. Anyway, in both case, the command box return to me : [warning] DisUnityCli: Parameter error: Expected a command, got extract ... Am I doing something wrong ? Or is it the tutorial ? Could you explain me please ? =/

I'm trying to extract, modify and then pack a .unity3d webplayer bundle. Looking at the readme, I need to unpack with the --prop option to generate a bundle property file which is needed to repack the bundle. However, when I use the --prop option, I get an error. The files are extracted, however no property file is created.

My file is main.unity3d, the output folder is unpacked

Running the command ./disunity.sh bundle unpack --output unpacked --prop main.unity3d gives me the output:

Hello,

I am a graduate student at Oregon State University and as a part of my research and subject CS562 Applied Software Engineering project (Study and Refactoring of Functional Interface in Java), I have done refactoring of the Function<T,Integer> to ToIntFunction.
My research and project deals with the boxing and unboxing of Wrapper class and the primitive data-types. I want to know that whether the open source community is ready to accept these micro-optimizing refactorings or not.

Thank you, Harsh Thakor
