FOSS gamedev and creative worlds

Has anyone found a solution to the following?

Linux Ubuntu 12.10 32 bit
Memory 1.8 GiB
Processor Core i5 CPU M 450 @ 2.40GHz x 4
Graphics Intel Ironlake Mobile x86/MMX/SSE2
Minetest 0.4.7

Minetest normally runs great, no lag. I experience an occasional bug that I am able to work through (usually from mods).

The problem I am experiencing does not seem to be a hardware related issue. I have searched different forums but, found only one other person with a similar issue.

It seems as though, anytime during game play, the player slips through the world and, falls infinitely into a void. The screen "world" turns gray (although the player and inventory are still there). Using F5 to view position shows that the player is falling.
Knocks FPS down from 50+ to 1.

It's as though a block disappears from beneath the player, then; the physics of the world get screwed up.

Previously, I've been able to / teleport back to 0,0,0. That no longer works.
I tried to / spawn, / respawn, / fly... no good. Invalid commands.
I pressed K - That put me in space. I see stars and a big square moon. Still falling. (this is all true dammit). No privilege to fly.
I changed the start position in the players "single player" txt. No help.
I tried to use teleport from space - still stuck.

Any ideas? Help is appreciated. Thanks

:( I dunno, seems like you are DOOMed.
Does this happen on all worlds?

Take a look at this topic

That's the problem exactly. updateListener error. Thank you for directing me to this topic. I believe I saw this topic before but, there's no solution there.

The first few times, teleport worked. Now nothing seems to work. Since others are having the same issue, I wonder if someone has the knowledge & ability to correct the problem?

Any help is appreciated. Thanks again.

You may be using singlenode mapgen

You're probably correct. I would tell you for sure if I knew what that was. I tried to research. I open to learning if you'll point me in the right direction.

I am guessing - there is such a thing as a multiple node mapgen?

If so, you believe this will fix the issue?

Singlenode is a 'Mapgen' choice when you start a new game. Click the little arrow to the right in the menu. I think the 'standard' choice is v6.


Edit: You can see what you chose when you open the file: minetest.conf.

For example I chose one time v6, so I have this in my minetest.conf:
mg_name = v6

Sorry. My menu in 0.4.7 doesn't seem to have the options (or I completely missed it).

I pasted the .conf file.

bilinear_filter = 1
creative_mode = 0
enable_3d_clouds = 1
enable_damage = 1
enable_particles = 1
enable_shaders = 2

mip_map = 1

new_style_leaves = 1
opaque_water = 1
port = 30002
preload_item_visuals = 1
selected_mainmenu_game = minetest
selected_mainmenu_tab = 0
selected_serverlist = 1
selected_world_path = /home/michael/.minetest/worlds/Magical land

Update: I was finally able to successfully teleport. Don't know why it didn't work the other times. Still, a solution to this "bug" or issue would be great. Thanks for spending the time on this.

By the way; what a great game! Very addicting.

My fault, I assumed you're using the latest 0.4.7 from GitHub, but I guess you're using 0.4.7 stable.

My recommendation is to start using the latest 0.4.7 from Github:
- Although not stable, most of the time the newer/later/unstable minetest builds are better than the stable
- Generally more mods that are working without problems and that are up to date
- AFAIK the 'falling bug' wasn't mentioned for months. 0.4.7 stable is relatively old (+- 5 months)

It's possible to port your world to the newer version (I never tried it myself).


I myself prefer to build minetest using the instructions under Compiling on GNU/Linux - https://github.com/minetest/minetest

Just copy and paste. Don't forget to put sudo in front of apt-get and to change directory to the name that appeared in your filemanager instead of this: cd minetest-minetest-286edd4 (or similar)

Fantastic. I'll download the Github version. This also explains why my .conf file was different. Thanks again!

OK. listenerUpdate error happened again. This time it was on a server that didn't allow teleport. I'm ready for Github. Do I need to remove all the existing folders or, just install the new program?

Quick answer:
I once had a system-wide installation of minetest. Without any problem I could install (more than one) run in place versions of minetest. So in that case, no, you don't need to remove all the existing folders.


Some background:

So, I don't think you need to remove the existing folders, but I don't know if that's true for installing a system wide version of minetest on a computer that already has a system wide version of minetest. I've no experience removing a system-wide version (my older computer broke down before I could try).

Using the compiling instructions I keep the default choice for a 'local' installation: DRUN_IN_PLACE=1.
It creates a minetest directory in my home directory like this
/home/topywo/minetest-minetest-382357d

Whenever I want a newer GitHub version, there's a new minetest folder created, with the latest version number. This means I can easily drag and drop (Lubuntu, so sometimes copy and paste) directories and files between the old and new versions. I could easily delete the older versions, but minetest doesn't need much disk-space, so when my home directory gets crowded I just move them to an archive directory. It's also very easy to copy and paste (and rename) minetest for trying out stuff (don't forget your hidden files).


Edit: Some corrections after rereading.
