Upgrading OneJS

You can upgrade OneJS as usual from Unity's Package Manager or through the OneJS private repo. If you encounter any issues, try deleting the ScriptLib folder and tsconfig.json file under OneJS's working directory (i.e. {ProjectDir}/OneJS). They'll be auto-regenerated by the new ScriptEngine.

If you are using Tailwind, make sure to run the tailwind compiler at least once to flush out any stale styling.

If any problem persists, please come to our Discord Server for assistance.
