Superflat World

[jordan4ibanez]

Here is a code i've been working on today to give superflat worlds with maximum speed

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

super_flat = true

if super_flat == true then
    minetest.register_alias("mapgen_air", "air")
    minetest.register_alias("mapgen_stone", "air")
    minetest.register_alias("mapgen_tree", "air")
    minetest.register_alias("mapgen_leaves", "air")
    minetest.register_alias("mapgen_apple", "air")
    minetest.register_alias("mapgen_water_source", "air")
    minetest.register_alias("mapgen_dirt", "air")
    minetest.register_alias("mapgen_sand", "air")
    minetest.register_alias("mapgen_gravel", "air")
    minetest.register_alias("mapgen_clay", "air")
    minetest.register_alias("mapgen_lava_source", "air")
    minetest.register_alias("mapgen_cobble", "air")
    minetest.register_alias("mapgen_mossycobble", "air")
    minetest.register_alias("mapgen_dirt_with_grass", "air")
    minetest.register_alias("mapgen_junglegrass", "air")
    minetest.register_alias("mapgen_stone_with_coal", "air")
    minetest.register_alias("mapgen_stone_with_iron", "air")
    minetest.register_alias("mapgen_mese", "air")
    minetest.register_alias("mapgen_desert_sand", "air")
    minetest.register_alias("mapgen_desert_stone", "air")
    minetest.register_alias("mapgen_papyrus", "air")
    minetest.register_alias("mapgen_cactus", "air")
    minetest.register_alias("mapgen_torch", "air")
    minetest.register_alias("mapgen_nyancat", "air")
    minetest.register_alias("mapgen_nyancat_rainbow", "air")
    --GENERATE THE SUPERFLAT WORLD
    minetest.register_on_generated(function(minp, maxp)
        if minp.y < 0 and maxp.y > 0 then
            orig = minp
            orig_x = minp.x
            pos = minp
            for i = 1,6400 do
                minetest.env:add_node(pos, {name="default:stone"})
                minetest.env:add_node({x=pos.x,y=pos.y+1,z=pos.z}, {name="default:dirt_with_grass"})
                pos.x = pos.x + 1
                if pos.x == orig_x + 80 then
                    pos.z = pos.z + 1
                    pos.x = orig_x
                end
            end
        end
    end)
end

I recommend using this to check the setting in minetest.conf:

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.setting_getbool("mapgen_super_flat")

Also, this will cause issues with ABMs that are builtin to the C++. For example, trees won't grow from saplings, and dirt wont turn to dirt_with_grass.

I used the flatland mod to extend my no_mapgen mod to do something similar. I don't know if yours is faster tho:

This does not cause any problems with any of that, and yes it does turn into grass

ok, thats interesting. i assumed a lot of things wouldnt happen when i did this on skyblock. i might have to go back and review the ABMs I added. some are probably not needed.

[cornernote]

perhaps I am mistaken (i dont know c++ that well), but this is the function that turns a sapling into a tree:
https://github.com/celeron55/minetest/blob/master/src/mapgen.cpp#L123

The ABM is defined here:
https://github.com/celeron55/minetest/blob/master/src/content_abm.cpp#L121

It seems to rely on mapgen_* aliases.

hmm the saplings do not work, i'll have to see about that

where is the flat world ?
How To use it ?

[breinzter11]

Now i got the flat world
this is cool !
