Generate some dirt underground

[londumas]

Hello,

I have some idea for maps, but for that I need to know how to generate a map that has "dirt" nodes underground.

Thank you

You could use WorldEdit to replace the stone with dirt

Thank you @sfan5 for your answer. But I don't want to replace all the stone, only to have some random "dirt" node underground along with stone, iron...

I guess you could make dirt generate like an ore... don't ask me how though :)

Change worldedit/manipulations.lua:37(for //set) or worldedit/manipulations.lua:65(for //replace)
from

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

env:add_node(pos, node)


to this, where 0.75(=75%) is the probability

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

if math.random() < 0.75 then env:add_node(pos, node) end


Then you can simply use //set or //replace and it will only randomly set 75% of the nodes

Cool, can I do that in a mod for a map?

[sfan5]

You mean that it auto-generates the dirt nodes?
That'd be possible, but using the worldedit method would be easier for you I think.

Untested.

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

minetest.register_ore({
    ore_type = "scatter",
    ore = "default:dirt",
    wherein = "default:stone",
    clust_scarcity = 8*8*8,
    clust_num_ores = 100,
--  ^ Number of ores in a cluster
    clust_size = 5,
    height_min = -31000,
    height_max = 0,
})

Dirt as ore is already default. I saw it very often.

Its not exactly an ore, its hardcoded in the v6 mapgen.

This should work.
