packr VS fxlauncher

LibGDX has their own way of doing this: https://github.com/libgdx/packr

Go to https://github.com/libgdx/packr, download a release on the releases page.

> they quickly realize they need Windows, and a Mac, and maybe Linux just to make packages that their friends can run

And when they test it on Windows they'll realize that the launcher that jpackage creates does something weird on startup (involving relaunching itself it seems?) that makes Windows display a busy cursor for a while after the program has launched, so they have to forget about jpackage and redo it all with something like Packr [1] and Wix# [2]...

You may also want to bundle a JVM with your game install so you don't have to rely on the user having Java installed. You can use libGDX-packr or jpackage for this. If you have any trouble, feel free to hit me up.

Try packr: https://github.com/libgdx/packr

Then see if this could work for you: https://github.com/libgdx/packr

https://stackoverflow.com/questions/2258932/embed-a-jre-in-a-windows-executable has some suggestions, one of which is https://github.com/libgdx/packr if you embed your Rust library within a JAR

If you are on a lower version I have made good experiences with the packr tool.

FXLauncher is both a launcher and an auto-updater that focuses solely on JavaFX applications.

Check out https://github.com/edvin/fxlauncher. I've never used this lib myself, but it seems to be intended for this very task. Or at least you might find some inspiration there.
