asset_migrator's Issues

Conversion Stage immediately exits & Non-BONELAB game question

I'm attempting to run asset_migrator.exe in Windows (10) Terminal in a D: drive, passing in my ripped project's Assets folder as the first argument and the destination Assets folder as the second. My final command looks like this:
.\asset_migrator.exe "D:\SteamLibrary\steamapps\common\<game>\<game>_Data\Ripped\<game>\ExportedProject\Assets" "D:\Dev Stuff\Projects\VS Community\Unity\My project\Assets"

The collection stage only lasts a couple seconds and the program exits silently immediately after the conversion stage.

Also possibly related, is there any BONELAB/IL2CPP-specific code in this? I'm asking because I'm ripping a game with a Mono backend.

Thread 'main' panicked at main.rs:162:72

Now I get an error, after using the correct syntax.
I set up a PowerShell script to help me with multiple scene files:

foreach ($file in Get-ChildItem "D:\SteamLibrary\steamapps\common\<game>\<game>_Data\Ripped\<game>\ExportedProject\Assets" -Recurse -Include "*.unity") {
    echo $file
    Start-Process -Wait -FilePath 'D:\Dev Stuff\Programs\PrefabConverter\asset_migrator.exe' -ArgumentList "`"D:\SteamLibrary\steamapps\common\<game>\<game>_Data\Ripped\<game>\ExportedProject\Assets`" `"D:\Dev Stuff\Projects\VS Community\Unity\My project\Assets`" `"($file)`"" -NoNewWindow
}

All it does is run the program for every .unity file in the ripped project directory. I've tried running the program by itself, and i get the same error as when i run it using the script:

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: StripPrefixError(())', src\main.rs:162:72
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

All I can gather from this error method, having very little knowledge in Rust, is that it can't get the .unity file's path because it somehow ends up as type 'Err'.

This app cant run on your pc

i have had this issue for a while now

Usability: Packages aren't factored into conversion process

Problem

Currently Asset Migrator only functions on the assets directory of a project

Solution

Ask the user for a project path instead, and factor packages into the process
