How to change world's name?

by Sergey » Post

Is it safe to change world's name just by renaming corresponding folder in ~/.minetest/worlds/ ?

In world's folder there are many data like metadata, map itself as sqlite database, and so on. Maybe world name is presented there as well.

How to change world's name correctly?

Are you running a complicated setup with multiple servers with multiple configurations and multiple other-things-to-consider..? If so, I have no idea if it's safe to rename, sorry.

But if not, if you're on a simple singleplayer Minetest like myself, read on...

I just used grep to search for a world's name (the text-string) recursively throughout the ~/.minetest folder and it only showed up in the debug.txt log, nowhere else --- suggesting it's not in the world's database or other files.

As a test, I just duplicated a world's folder under a changed name using :

Code: Select all

cp  -T  -a   ./OLD_WORLD_NAME   ./NEW_WORLD_NAME
and the duplicate showed in the GUI list then seemed to launch okay.

I just renamed the duplicate world's folder with :

Code: Select all

mv  -T  -v   ./NEW_WORLD_NAME   ./DIFFERENT_WORLD_NAME
and this too showed in the GUI list and seemed to launch okay.

These quick toe-in-the-water tests suggest yes, it's probably safe to rename the folder to a different world name.

So, unless you're multi-gigabytes into an un-backed-up game-world I'd suggest just going ahead and trying it.

But I'm a still-learning noob, so the advice is always ''Make Back-ups'' and please don't experiment if you're not willing to risk breaking everything ;-P

HTH

Yes, I play singleplayer mode. Honestly, I don't understand how to play on servers with many other players. I installed MT not so long ago, about two weeks ago, and I just enjoy playing constructor.

Ah, no problem, that's not too tricky ...

Obviously you'll need to be connected to the network where the servers are --- whether it's your mate's LAN or the wider internet.

After you launch the Minetest application, in the GUI window, click the second tab --- labelled ''Client'' --- then give it a moment to grab and update its information.

You'll see stars and numbers and cubes and hearts and crossed swords beside the names of the publicly-available worlds.

Image

The numbers indicate how many players there are logged-in for each server, out of a maximum-number allowed.

The cube/heart/sword icons indicate what type of server it is, what features are enabled --- Creative, Survival, PvP (player vs player fighting/killing).

The stars show Favourites, but you can add/remove those.

Browse down the server-list to see what's there and read the little descriptions ... although don't expect too much, not all are well described in the text-box, and annoyingly, a number of them overflow but there's no scroll-down so they're impossible to fully read.

Some include website addresses for more information, and it's generally a good idea to check those out first before wasting time or bandwidth joining up.

You can often get some idea whether a server is truly for the General Public from the numbers ... if it shows small number-allowed and most of those are taken, e.g. '' 4 / 5 '', it's quite possible it's just a small server for a family's kids and their mates. Remember, there's a wide range of ages and types and temperaments playing Minetest for a whole range of reasons.

Not all those who set up a server are tech-savvy. If you find you try one that's effectively a private server on the public list, just be respectful if asked to leave.

Anyway, once you've decided and selected a server you want to try, double-check any instructions about signing-up --- some servers require you to go to their community-websites.

Otherwise just enter your chosen player-name and a password of your choice and click ''connect'' --- and if that fails it will usually pop up a message telling you why ... name already taken, specific password required on first join which you then change after login, whatever whatever. Many server-owners have naming and password policies for very good reasons.

Once you're accepted/connected, on some servers it may take a couple of minutes to download all the textures and other media, just be patient.

A word of warning : if you're on a metered data-capped internet-connection, the size of the initial-download and the minute-by-minute data-consumption may be something to watch closely --- on some servers I've seen almost 200 MB initial media downloads and then over 1 MB per-minute data-rates ... you can blow through many gigabytes in a month ... ouch!

Most are not that bad.

Finally I would heartily recommend looking at the Servers section of the forum ... there are lots of interesting worlds to explore and the threads in Servers do give some idea of both what to expect and what is expected of you as a player joining them.

Dependent on your own gaming preferences, the most popular servers (by player numbers) may not be the best choices.

Take a little while to audition different servers, follow the guides and rules, and you'll probably settle into some before too long.

Hope you have fun.

There can be several problems that cause this view, but please check first your debug.txt file and terminal output text (start Minetest from command line it there's no terminal).

1) Missing cURL library: run "minetest --version" and look out for the value of USE_CURL. For a value of "=1", goto number 2, otherwise get another Minetest build (0.4.15 prefered) or build your own with cURL
2) The connection timed out: Your connection is simply too slow, check the server list manually
3) You messed with the master server URL or someone changed it for you. Remove the entire line "serverlist_url = ...." from your minetest.conf setting
4) Yet an unknown bug, please report all warning/error messages you can find about it

Yes. Close all running instances of minetest and simply rename that directory. There will be no problems with it. The functionality of all mods and the world itself will be the same as before, don't worry.
Look, I programmed a bug for you. >> Mod Search Engine << - Mods by Krock - DuckDuckGo mod search bang: !mtmod <keyword here>

My Internet connection is indeed slow. I know it because I have ADSL connection using phone line with 6MiB for download and 512 KiB for upload.
