A short note: I spoke about this rough and quick assetpacker tool that we used in a few released luxe games before now. People have asked me for it over time but I hadn't gotten around to making it work against latest code I and haven't looked at the messy code in long.

(I had also been working on the final luxe design which removes the need for this tool, but more on that in the dev logs!).

I updated it to work with latest luxe, so you can try and use it if you like - no promises though - it was made in no time at all! The repo has all the details and nuance and code you need to use it:

Also note that the data files it generates are not specific to luxe, you can use the packed assets elsewhere, see the readme!

Any feedback can be posted on the assetpacker repo.
Enjoy!
