[Mod] MapGenerator - regular maps by Lua [lualandmg]

[Krock]

LuaLandMG
Previously called "yappy". Name change due large backwards compatibility break.

This mapgen is written in Lua, designed to offer a slightly different landscape than available in mgv6.

Old, some really old screenshots

Features:

• Trees: Apple, Pine and Oak
• Cactus
• Ores: Custom system replaced by the Lua API function (WIP)
• Caves: Empty or filled with lava
• Biomes: Desert, Grasslands and Arctic with overlapping, smaller biomes in between
• Water: Normal, Ice form or none, when too hot
• Mudflow: Makes cave entrances fancy

What it uses:

• 4x 2D-perlin noise: Used above -80m for terrain/mountain height, tree generation and temperature[/i]
• 1x 3D-perlin noise: Cave generation

Licenses:
Codes and textures: BSD 3-Clause
Pine tree from HeroOfTheWinds and paramat: WTFPL

Depends: default, flowers

Very neat, I'll have to try this out later. Pretty much any mapgen with rivers is neat in my book. Question though: why do those trees have some off-white in the texture? Is that some sort of alpha error with fancy trees off?

Also, the pine tree is paramat's originally, mine is just a plain ol' copy of his. xD

Very good. I am looking for a good magpen for my indev subgame. I liked mg, but It really wasn't working out... Your other one was rather promising, but not quite good enough. Anyhoo, I'll be watching this topic pretty closely.

I'll try to fix this bug soon.

I already thought, it could be a copy of paramat's mapgen, so I just added both names.

Anyhoo, I'll be watching this topic pretty closely.

Nice to see someone interested in this mapgen :)

Feature! Under the 1st layer is sand, cacti loves sand.

Hi, i saw this on IRC logs:
* Krock wonders if there's something like <PerlinNoise>:get3d(x, y, z) and which returns a number
There is but it's not well documented, see my very early (pre voxelmanip, pre perlinmap) mods.

In the parameters section set the noise parameters:

Code: Select all

local SEEDDIFF = 1975
local OCTAVES = 5
local PERSISTENCE = 0.6
local SCALE = 384

Here 'SCALE' equals the 'spread' of perlinmap noise parameters, the size in nodes of the largest pattern found in the noise. It has one value instead of 3 so applies to all 3 dimensions.
'SEEDDIFF' is the same value as 'seed' in perlinmap noise values.

Then use this once:

Code: Select all

local perlin = minetest.get_perlin(SEEDDIFF, OCTAVES, PERSISTENCE, SCALE)

Then you can get multiple noise values of any points in the world by using this multiple times:

Code: Select all

local noise = perlin:get2d({x=x,y=z})

Where x and z are the world co-ordinates.
Note 'x=x, y=z' because 2d noise always expects 2 values x and y and you're inputting the world co-ordinates x and z.
For 3D noise:

Code: Select all

local noise = perlin:get3d({x=x,y=y,z=z})

Thanks for your explanation, other IRC users were also able to help with that.
I searched that function on the wrong part in the lua_api (minetest.get_perlin_map).
Could you extend minetest.get_perlin at the dev wiki with your explantation, so it's easier to understand?
(Future) mod developers could appreciate that.

Your screenshot 2 posts above looks lovely, those appletree leaves do not though, they need a dark background behind the leaves, they look like cobblestone from a distance ;)

;)

I'll be taking a look at the latest sooner or later, so please, keep it up Krock. :)

Well, I dropped this feature now and added:

- clay (in sand, underwater)
- jungle trees (from default game)
- jungle grass

I would like and almost use this magpen all the time, except for one thing. It lacks a bit of interest. One suggestion; Add things like birch and oak trees in the mix with forests. I would do it myself (and I just might) but I am too lazy. :)

[Calinou]

Update!
- Added a simple mudflow
- Made caves generating also at surface

What is mudflow?

Without:

And with:

Heh, mud flow is explicity disabled in new worlds created with Carbone (to make world generation a bit faster and better-looking).

Asked & added:

Krock presents: Oak trees

Seriously? Do you think the stone-only screenshot looks better than the one, overed with dirt?

[Inocudom]

In the snow biomes, the ice goes far, far underground. I have seen lava caves, diamonds, and mese in it, in fact.

Are you planning to post this mod in the Freeminer forums and test it there? It seems Freeminer doesn't have LuaVoxelManip anymore, but I need a second opinion.

[paramat]

Krock i prefer your mudflow to no mudflow. You can avoid generating overhanging unstable dirt and sand by using my stability table system as demonstrated in my 'stability' mod.

I combined mudflow with stability now. (desert) sand will have a (desert) stone under it.

Added better biome borders!


Interesting what 1 new line and 1 changed line of code can do..

[ExeterDad]

Borders with a more gradual transition, nice feature.

That looks awesome.

Thanks.

And this is how caves look right now:
