Minetest Forums

working on 1.3 to play with the recipe in main, hopefully will get something that is playable in real tiem

it's more like a music visualizer than a typical terrain generator in programming style

what called a fractal "octave" on fractal forums is handled as a function in a function callback upto 3 octaves then it force breakout

there is some fractal, some perlin and some convolution matrix all packed together with lua callbacks

nice, the borg are the borg

bump for Discord

try playing with the last few lines, especially callback order

I improved a few things. For one I found returning a singleton is faster than an empty list in one of my functions. Secondly, I have increased the complexity while dropping the calc time order of magnitude. The original link above will download the new version. Chunk gen is now about 8 seconds.

I'll update the license.

I did use this algorithm on a core2 duo with 1 gig of ram and it took hours for a decent number of chunks did load. So that's why I recommend big CPU. You might get away with less and a big GPU.

I like that you assume I have never played a block miner game before.

A map generator that uses a noise fractal and plot random spheroids I call polyglobs. I developed the algorithm originally for Java in another project for testing a-life. It is very beefy so I recommend you don't use unless you have at least a quad core with 4 gigs of free memory. This is more of an...

~='ignore' works for me. I think testing 'if loaded' the closest solution I'll get with the current lua API. I'll have to pick through github to see if I can expose a sqlite query to lua to test 'if generated'.

local c_nil = minetest.get_content_id("ignore") if minetest.get_node(pos)==c_nil then --true end This looks valid. These are good ideas. get_node_or_nil is undocumented in wiki. So am I right in assuming only asynchronous sqlite transactions are available to lua? (vm:get_data() and vm:wri...

Hi everyone. I'm working on a mapgen mod that adapts genmud (old text-based rpg) code to lua. I'm looking for a way to test if a chunk has generated. Is there a null or something if I try to get a node that hasn't been generated yet? Some of the features I'm adapting (such as connecting roads) will ...

This would work nicely with the questing mod that I've just started to work on. Basically there are blocks in the game called quest blocks and when you step on one: game pauses and you get a renpy window. Renpy is here www.renpy.org / Basically, a block that launches a visual novel script in a minet...

Ok, tables are 1-based and I had written 0-based loops in my sum functions. Yay for the print function. Functions in functions work fine for me and make my code cleaner. Moving things around though gave me the idea to generate debug output. (Duh-copter.) Thanks for the impetus, Krock.

No, that doesn't work. I use the correct form of the get_node method according to the developer wiki. It seems to be nil from the generate_chunk function but it looks correct to me. Somewhere, I'm referencing and passing another value like perhaps the index instead of the table.

The stack trace starts at get_matter(point) with "attempting to index a nil" meaning x, y or z properties are not being set from VoxelArea:position or is being changed to a nil by my code.

I have a lua error and I kEep trying to iron this out but my point (voxel) is nil when I try to pass it to the function in a mapgen. Here's the code. I need a fresh pair of eyes to spot the problem. minetest.register_on_generated(function(minp, maxp, seed) local limit={ XMIN = -33000, XMAX = 33000, ...

So what you need is a way to run two server instances and to bounce the connected client to the second server. You'll need two configuration files on the host machine, probably two copies of the minetestserver binary, each with its own config file. (Or a fork server but that's even more complicated)...

That sounds like it could be folder permissions. What are the permissions on your minetest folder? I'm no expert (anymore) but if you're on a newer version of Windows and you install to Program Files there could be restrictions preventing mod installation. So I've heard. Installing to a user directo...

Yeah that fixed things. I pooched the manual update. Sorry and thanks.

Yes, there are cactus, etc on the mapgenv6 ans mapgenv7 produces just default:stone and water. It seems to me from testing that minetest.on_generate is being processed but the minetest.update_map isn't pushing changes to the map on any of the lua maps. I'm going to try a full reinstall to resolve po...

Issue: lua mapgen seems to have no effect. I have tried several lua mapgen implementations (mods) but it seems the mapgen + seed in gui overrides the mod code and I'm stuck with vanilla every time. Minetest_game and the mod game both produce identical worlds. What are recommended settings or the pre...
