Minetest 0.4.15: clean the surface game and biomes

[Codesound]

Windows10_x64, Minetest 0.4.15_x64
Hi,

- In all the mapgens, there is a way to generate less mountains (or hills), holes (caves), the sea, so that the playing surface a bit more clean and extended?

- also you can make sure that the biomes are much larger? Currently, in a day's walk I see them all ...

what I wrong?

Many and many thanks for all!!!

To disable caves you will need to set the "nocaves" flag for mg_flags in the your map_meta.txt file. As an alternative, I made a patch for the mgv7 cave generator so that you can disable just the caverns (those gigantic caves), but still allow tunnels (the smaller, scattered caves) and only at specified depths. My cave patch only works for Minetest 0.4.13, altho I have updates in the works for later releases.

Option 1:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

mg_flags = trees, nocaves, nodungeons, noflat, light, decorations

Option 2 (with cave patch):

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

mg_name = v7
mgv7_spflags = nomountains, ridges, nocaverns, tunnels
caves_bedrock_level = -8000
caves_surface_level = -70


As for eliminating mountains and rivers, that will require setting the "nomountains" and "noridges" flags of mgv7_spflags. Keep in mind you might still get some wild looking cliffs and valleys, so you'll definitely want to fine tune "mgv7_np_terrain_persist" as well as "mgv7_np_height_select". These settings should produce a much flatter landscape, with a few occasional hills and more gradual inclines:

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

mgv7_np_height_select = {
        flags = defaults
        lacunarity = 2
        octaves = 4
        offset = -0.5
        persistence = 0.69
        scale = 1
        seed = 4213
        spread = (500,500,500)

mgv7_np_terrain_persist = {
        flags = defaults
        lacunarity = 2
        octaves = 3
        offset = 0.6
        persistence = 0.6
        scale = 0.1
        seed = 539
        spread = (500,500,500)
}
mgv7_spflags = nomountains, noridges, nocaverns, tunnels


You can adjust the biomes within the mapgen.lua file from the "default" mod of minetest_game (look for the section titled "Register biomes"). The parameters that you are concerned with are heat_point, humidity_point, y_min, and y_max.

Hi,

many and many thanks for your reply!
I'll try your suggestions in the next few days.... thanks again.....

It's complex to undrstand, but altering the mapgen noise parameters can radically reshape the world and the caves. There's also a 'cave width' parameter in all mapgens except mgv6.

See the first 29 lines of this mod for how to adjust biome size https://github.com/paramat/newbiomes/blob/master/init.lua just increase the 'spread' numbers from 1000 to something bigger.
You can also set these heat/humidity noise parameters in minetest.conf (see minetest.conf.example for how) or in advanced settings.

I do not know if this is correlated, but some default settiings is not really default.

New zip minetest 0.4.15:

max_block_generate_distance 7

Restore to default:

max_block_generate_distance 6

mg_flags dungeons

Restore to default:

mg_flags caves,dungeons,light,decorations

What are settings really default? What are best settings?

Thanks!

Hi,

I tried with your suggestions and now works! No caverns, no dungeons, the surface is cleaned.
the "magic" string is:
mg_flags = nocaves, nodungeons, light, decorations

but the order of the operations is very important!
1 - I create one world
2 - I change the script
3 - I start the world

If I start the world just made BEFORE you change the script, the changes do not appear....

a very important thing that I did not know, is the close relationship that it has with the script and the game: many and many changes is possible only just changing the script....

thanks at all.....

Thank you for that info - is there a way to selectively increase/decrease biome size?

[paramat]

You mean adjust biome size per-biome? Yes, you will need to edit the 'heat/humidity points', the size of the voronoi cells shown here https://forum.minetest.net/viewtopic.php?f=18&t=15939 controls biome size.
