OK I found this program to do it. https://github.com/ata4/disunity But it's all command prompt based. I have no idea how to input commands in command prompt. Oh mighty Pengu help me! Usage disunity -c <command> <file> Note: depending on the platform, you may need to run disunity.bat (Windows) or disunity.sh (Linux/MacOS). In case the launch script fails, try java -jar disunity.jar. Commands dump - Converts the asset file to plain text, similar to the binary2text tool shipped with the Unity editor. dump-struct - Like dump, but just for the data structure. extract - Extracts supported asset content and stores it in regular files. Default command if the -c parameter is omitted. extract-raw - Extracts the raw serialized binary data from the asset. learn - Learns the structure from an Unity webplayer bundle (*.unity3d) and stores any new structs in the database file structdb.dat. Its data is required to deserialize standalone asset files, which usually don't contain any structure data. info - Outputs various information for assets and asset bundle files. info-stats - Outputs class usage statistics for asset files. unbundle - Extracts Unity webplayer bundles (*.unity3d). fixrefs - Fixes shared asset references in extracted scene files by converting relative to absolute paths so they can be opened with the Unity editor correctly. Note: If the shared assets are moved to a different folder, the scene needs to be fixed again. split - Attempts to split an asset file into multiple smaller asset files. list - Lists all objects and files in a tabular form. Other parameters Run disunity with the -h parameter for further usage.
Command prompt is somewhat easy if you are used to linux terminals. 1. Open Command Prompt The command cd is for Changing Directory example: cd Documents 2. Navigate to the directory containing disunity For a file, you will need a directory and the file with extension. An example "C:\Users\Karl\Documents\test.txt" 3. type disunity -c (yourcommandhere such as dump) "C:\..." 4. press enter 5. things will display in the command prompt 6. respond to any questions the program asks 7. kaboom! You are probably done. If not repeat 3-6 for each file.
Sounds complicated. I will do it tomorrow after I get some sleep. Also, I see this Dependencies ioutils lzmajio apache-commons-cli-1.2 apache-commons-io-2.4 apache-commons-lang3-3.1 Does this mean I will have to download those things too?
Very likely. My understanding is that the .unity3d file is a "web player" asset file. I suspect what's happening is the decompiler has to pretend to be running it on a web page to get access to the contents of said file.
But you can still make unity standalone games without a browser. Or is it coded om some kind of "fake" browser.
I suspect the web browser method is probably the easiest and most cross-platform way to decompile the asset files.
