Custom maps / mods support?

[WofWca]

Yes, it's possible. Similarly to #1, it's only a matter of adding files to the "filesystem", which we already do.

We might need to toggle cl_allowdownload 1.

I think this can be achieved by simply letting users modify the Emscripten FS.

quake3.xdc/index.html

Lines 679 to 722 in cd5e97b

	module.FS.mkdirTree('/home/web_user/.q3a');
	module.FS.mount(module.FS.filesystems.IDBFS, {}, '/home/web_user/.q3a');
	let idbfsReadyResolve = null;
	const idbfsReady = new Promise(r=>idbfsReadyResolve=r);
	module.FS.syncfs(true, (err) => {
	if (err) { console.error(err); debugger; }
	idbfsReadyResolve();
	});
	await idbfsReady;
	try {
	// TODO maybe preserve the config when switching
	// between demo and full game?
	if(!module.FS.analyzePath(`/home/web_user/.q3a/${basegame}/q3config.cfg`).exists) {
	module.arguments.push(...`
	+set model "${model}"
	+set headmodel "${model}"
	+set name "${username}"
	`.trim().split(/\s+/));
	} else {
	// Read the existing q3config.cfg and update the name and model in case the user changed them.
	const q3config = module.FS.readFile(`/home/web_user/.q3a/${basegame}/q3config.cfg`, { encoding: 'utf8' });
	const lines = q3config.split('\n');
	for (let i = 0; i < lines.length; i++) {
	if (lines[i].startsWith('seta name')) {
	localStorage.setItem('username', lines[i].split('"')[1]);
	} else if (lines[i].startsWith('seta model') || lines[i].startsWith('seta headmodel')) {
	localStorage.setItem('model', lines[i].split('"')[1]);
	}
	}
	}
	} catch (err) {
	console.error('Error reading q3config.cfg:', err);
	}
	saveFiles = () => {
	module.FS.syncfs(false, (err) => {
	if (err) { console.error(err); debugger; }
	});
	};
	saveFiles();
	module.FS.mkdirTree(`/${basegame}`);
	const pk3Files = await pk3FilesPromise;
	await Promise.all(pk3Files.map(async ([filePath, file]) => {
	module.FS.writeFile(filePath, await file);
	}));

This would also solve #3 along the way.

I've also been considering packaging some mods by default. I'll just dump some info about it here:

I've been considering adding the Unlagged mod, given the not the best ping conditions. It seems to work.
Also https://github.com/ec-/baseq3a includes the Unlagged mod, and I also managed to make it work, but I had to disable the built-in ztm-flexible-hud.

I also looked at the OSP mod. It's quite fun and not too invasive, but then I thought that at this point it's simpler to just provide mod support and let people figure it out, with some pointers like "here are some mods you can try".

The thing that I would really like to enable by default would be adding a vote menu, to execute e.g. \callvote map q3dm17, where you can pick maps, or just vote to go to next map. But I was not able to find a mod that does just this. Here are some issues / MRs I found that are related to this:

• New UI Project clover-moe/spearmint#48
• Comfortably start a new map from within ingame menu. clover-moe/mint-arena#7 - I wonder if we can turn this into a mod, as opposed to having to recompile ioquake3.
