What is BuildLauncher

BuildLauncher is a frontend for Build Engine games inspired by nstlaurent's DoomLauncher It can download all major ports for Build Engine games, as well as mods, custom campaigns, and maps and launch them with the port of your choice. Another goal of this project is to create a unification standard for Build Engine mods, campaigns, and map, so they can be launched with supported ports without any additional tweaking by users.

How to use

Download the Windows x64 archive from the releases page and extract it to a writable folder. On Windows, run BuildLauncher.exe. For Linux x64, publish from the repository root with dotnet publish src/Avalonia.Desktop -p:PublishProfile=Linux -c Release -o ./publish/linux-x64, then run ./BuildLauncher from publish/linux-x64/. If the executable permission was lost during extraction, run chmod +x BuildLauncher first. The automated release workflow currently publishes Windows x64 only. The launcher uses its application folder as the working directory. Use --dev to open the addon authoring tools. On Windows, use --offline with the repository's db/ folder beside the executable for local metadata. Offline JSON lookup on Linux is a known limitation in this revision.
