You think you've seen it all and then there's a Wayland Compositor inside Minecraft on Linux

I'm not sure why you would want to do this, but you can run a Linux Wayland Compositor inside Minecraft to get various external windows inside the game.

Of course, in doubt the answer to this question always is: "Because I can!"

That is really cool.😀

Work hard, play hard! Now even at the same time!

Meetings in Minecraft - coming soon 😆

And here I was thinking that virtual machine mod was the peak of what we could do.

When I was a kid, this is what I thought all computing would be like. It's taken nearly 40 years of disappointment to get here.

This was an incredible project to try yesterday. Just note that unincluded in the requirements, your distro needs glibc v2.43, and if playing with Prism Launcher (or any other launcher) ensure that you give the flatpaks the right file permissions to use said glibc, or use a different Prism Launcher package like the one from the AUR.

This is how I'm pulling up to college today. Why? Rule of cool + if it works, use it.

And next? A game with ingame phone (like GTA, but please something cooler than GTA) running Phosh on it? Then playing the mobile version of that game inside the game. That would be awesome.

I wondered for a moment if we can run Doom inside of Doom.

Yes, we can.

Yes, we can.

But can you run Quake inside of Duke Nukem 3D inside of Doom on your refrigerator?

I've finally run emacs inside Minecraft ... fine; but I think what I really want to do is to run Minecraft inside emacs.

In theory you would then be able to run emacs inside Minecraft inside emacs.

I mean, strictly speaking this is 'displaying inside' as opposed to *running inside*; so that kind of recursion wouldn't be a big deal, not so different from the infinite tunnel you get when streaming the desktop with an OBS window inside it, etc.

Not sure about an emacs native wayland compositor, but emacs is already able to launch image buffers, satellite windows, etc.; so in that flimsy sense, emacs too can display Minecraft inside it.

... but the thing is that both Minecraft and emacs can *theoretically* 'run' each other as computers ... though it wouldn't be practical in the least. emacs still has a better chance of course, especially since it can have plugins written in C; but implementing at least a 32 bit computer using redstone inside Minecraft, etc. etc., that's a tall order.

This is really wonderful to see! I love creativity.

Give either EXWM or EWM a try?
