FOSS gamedev and creative worlds

Can I rerun mapgen on a region somehow?
I have a very old world and some parts of it were generated with old generators. I want to regenerate them with current generator. Is this possible with this mod or any other?

I don't know why that would make sense. The leaves must be removed/updated anyway - somewhen. Just use a higher "chance" variable to spread the load. Chance is to limit the "in-game speed". This means if I want the trees to grow slowly, I'll lower the chance. But what if I want ...

As my nature mod was very heavy with many of the ABMs on leaves, I introduced a "limited" which disallows my ABMs to be run more than a number of times per time unit. I think this is a useful thing and could be added to minetest engine or at least the ABM API (add some "limit" pa...

In the latest commits I added the mechanism to prevent server overload when there is too much tree, moss or anything else. Now only a limited number of actions can be run per a time unit (usually second or more), and after a passing of time nothing will be run. I will add some more optimizations and...

Updates in 1.2.0: Removed cactus and papyrus growing. I found out they already grow in the default mod, so... Refactored moss and tree growth, it should be fasted now. Moss grows only in dark places AND close to water. Also I've finally added cavenature to the stable mod version. In future I intend ...

The problem is: Both languages are interpreted. Interpreted languages are always slower than compiled languages performing the same task. I’m happy that the Minetest code is written in a compiled language for all the critical tasks. I wish mods would use Python instead of Lua but that’s not that mu...

If minetest was in python or java... I’m happy that it isn’t. Python is awesome and Java is …uhm … versatile … in a way. But both aren’t optimized for performance. Don't judge them on the software you seen on the internet. They can be very perfomant, but you won't see good optimized java applicatio...

In the sims 3, each object has its own thread. It works because they can request a resource and lock it. You would need to completely redesign the modding API. It is very unlikely to happen. Why do you have to break or change anything? The only thing that will be locked is working with the server (...

Lua runs on one thread - you can notice the lag when a Lua mapgen generates terrain.

Does anyone work to make it use more threads? I think this would greatly improve performance. Or am I wrong?

Does minetest use one threads for all mods now or a thread per each mod?

is your matches mod going to be updated? mabey to use the default fire if the default fire is installed?

ONTOPIC

nice mod

When the default fire mod was implemented, I thought there are already some igniters there. If there aren't, I can update my mod to work with it.

Appears to work just fine. I'll make the fungus "grow" algorithm and then release a new version of nature. As for now you can update from the repo, it works fine (tested on my server).

Texture:

Great, thanks! I'll try that one now.

Hmm, maybe we need less overlay and more half-tones? I mean like in the coal texture next to it. There are only several black coal lines, they do not cover the whole stone block like in your one.

Great, I'll take a look on it in the game now.

Esteban wrote:Would you like this texture? Or a different one?

Could you make it in blue or violet colors? In my imagination the illuminating fungus is more bright, and blue is a "dark light" color. Does this sound reasonable?

I can give a try! What type of fungus you want? the classic view of fungus? moss looking? I want a moss looking fungus cause it will act similar to moss. It will appear in the dark caves instead of the stone blocks and will "grow" (less bright fungus blocks will become brighter), and it w...

I'm looking to making fungus stone blocks in the dark caves that could give some nature light into the caves and corridors. For this I need 3 or 4 fungus texture I will overlay on the stone texture. The difference will be the fungus "level": the more it is grown the more light it will give...

Well, you can just disable some mods from the plantlife and you will get a fast plantlife. But plantlife adds new plants, so I can concentrate on working with the existing ones. Just out of ideas now. Growing stone is too hardcore, footsteps already exist.

A lightweight nature modpack would be very very welcome :-) One that concentrates on speed, while still looking nice and adding more nature to the default game. It's no problem to concentrate on speed. I just don't understand well what the mod should do. All that I wanted seems to be in the plantli...

Maybe these additional flowers could then be placed into one new mod so that they can be used in combination with minetest_game. I have to rethink the purpose of my mod as I looked over the plantlife mod and it does the things were done in nature. Its bushes are prettier :) Maybe I'll just concentr...

Most of the nature modpack got included in the plantlife modpack, as Inocudom already said. Due to the huge amount of plants and the way plants can define how their environment ought to be, plantlife still isn't fast, so there's more than enough room for additional mods. Plantlife creates extremly ...

I can tell now what exactly I want to speedup. I am the only player on the server, and when I try to open or close a door there is sometimes a 1-2 second lag. Minetest process does not take too much CPU or ram, so it's not the PC performance issue. Something in the game engine is very slow, and I tr...

Your server? Get a better one.
Your Harddisk? Defrag it.

btrfs does not fragment :P
I'm just thinking, not trying to speedup a particular server. Will putting it to tmpfs give a profit?

Yeah, I know that. I'm talking about speeding it up from out of minetest.

http://voxelands.com/

Freeminer seems to be dead, there are no updates for very long and no servers in the official server list. But I see voxelands for the first time, I'll check it.

What are the tricks to speed up the server? The first that comes in mind is to put the world into tmpfs and sync it with the disk once an hour or so. Will this work, or minetest already holds the active map in memory and putting the whole world there will be useless?

When was the last version you used? The game now has a lot of cool stuff to be released in 4.11: fire looks like MCs, node highlighting (no more black square), Meshes (3d models) can be used for nodes, and more! :D Well, my mods were really updated a year or more ago. My mods are mostly for operati...

The funny thing is I don't even know if the code is still "good". Maybe some new features were added to the API. But the good thing is that it's still working so nothing was removed :D
