I'm slightly confused, I'm trying to learn and understand the code here, mauvebic, did your code create air inside the structures only?

I ask because I'm inspired to possibly try my hand at recreating the planet 'Diamond' where the sunlight is toxic, and people must be protected by thick sheets of glass. is it possible to have the toxic atmosphere flow downward, and have air generator blocks that would allow the building of structures in a toxic environment?

Im just building though. Considering ive been waiting two years for a genuine space map, it's hardly surprising this mod piqued my interest :p As for development, that requires more patience for rudeness and politics than what i got lol

I'lll keep posting shots of my base as it progresses (unless paramat asks me to move them) :-)

Naw it doesn't matter where the leaves are (indoor or outdoors), they just create air by replacing neighbouring voids. The other abm' moves the air nodes towards (neighbouring) void. So a dome is only there to keep the air in. Without a dome, the air nodes would scatter in every direction.

Thanks for the reply. I see now in the code where you have the trees generating air. So it would be possible to add on an atmosphere generating machine, rather than trees.

I really need to read up on the minetest API.

yeah if you want a machine to do the air-generating, just change the leaves abm so that it works on your generator node instead :-)

Version 0.3.0 was released with some experimental parameters:
Code: Select all
local HEXP = 1.5
local LEXP = 3

Now i'm not sure i like the terrain, so, if you want the classic moonrealm terrain from versions 0.1.0 and 0.2.0 (screens below) you should edit these to:
Code: Select all
local HEXP = 2
local LEXP = 2

These are the 'crazyness' parameters for the higher and lower terrain, and define the cliffs ... set to 1 results in standard 3D perlin noise landscape, 2 and above for cliffs, overhangs, 'floaty bits', tunnels, spikes. Remember this can be set to fractional values and below 1 ... it should be fine tuned to your taste.

I was inspired by mauvebic's use of air generation to experiment ... managed to clear a small room in about 2 minutes. Its funny i hadn't thought of trees duh ...
First time i tried i managed to get an air leak through a diagonal corner situation ... its scary once my air gets out it spreads quick ... the game quickly headed for abm meltdown.
So yeah this'll be in 0.4.0.
Also, the dust colours were not carefully chosen i assumed most of you would change the textures to your taste?
Anyways code.
Code: Select all
minetest.register_node("moonrealm:airgen", {
    description = "Air Generator",
    tiles = {"moonrealm_airgen.png"},
    groups = {dig_immediate=1},
    sounds = default.node_sound_stone_defaults(),
    on_construct = function(pos)
        local env = minetest.env
        local x = pos.x
        local y = pos.y
        local z = pos.z
        for i = -1,1 do
        for j = -1,1 do
        for k = -1,1 do
            if not (i == 0 and j == 0 and k == 0) then
                local nodename = env:get_node({x=x+i,y=y+j,z=z+k}).name
                if nodename == "moonrealm:atmos" then
                    env:add_node({x=x+i,y=y+j,z=z+k},{name="moonrealm:air"})
                end
            end
        end
        end
        end
       
    end
})

-- On dignode. Atmosphere flows into a dug hole.

if ATMOS then
    minetest.register_on_dignode(function(pos, oldnode, digger)
        local env = minetest.env
        local x = pos.x
        local y = pos.y
        local z = pos.z
        for i = -1,1 do
        for j = -1,1 do
        for k = -1,1 do
            if not (i == 0 and j == 0 and k == 0) then
                local nodename = env:get_node({x=x+i,y=y+j,z=z+k}).name
                if nodename == "moonrealm:atmos" then   
                    env:add_node({x=x,y=y,z=z},{name="moonrealm:atmos"})
                    return
                end
            end
        end
        end
        end
    end)
end

-- Abm.

if ATMOS then
    minetest.register_abm({
        nodenames = {"moonrealm:air"},
        neighbors = {"moonrealm:atmos"},
        interval = AIRINT,
        chance = 9,
        action = function(pos, node, active_object_count, active_object_count_wider)
            local env = minetest.env
            local x = pos.x
            local y = pos.y
            local z = pos.z
            for i = -1,1 do
            for j = -1,1 do
            for k = -1,1 do
                if not (i == 0 and j == 0 and k == 0) then
                    local nodename = env:get_node({x=x+i,y=y+j,z=z+k}).name
                    if nodename == "moonrealm:atmos" then
                        env:add_node({x=x+i,y=y+j,z=z+k},{name="moonrealm:air"})
                        print ("[moonrealm] Air spreads ("..i.." "..j.." "..k..")")
                    end
                end
            end
            end
            end
        end
    })

You need generators in the beginning anyhow, trees won't spawn in atmosphere, though i'd still use both (large structures need the help). If my code had been less laggy, i would have also made air and/or water turn moondust to dirt, essentially terraforming.

Indev stuff for 0.4.0:
Added iron ore and considering ore / ores for oxygen / nitrogen extraction needed for the air generator.
Water ice spawns in dust at high altitudes, can be crafted to a bucket of water, this then could be crafted to a hydroponic liquid which makes only one of the dusts suitable for growing.

Okay the air generator recipe includes water ice which is the source of the artificial atmosphere.
There is an airlock in that gap, walkable = false so you pass through but it stops the base air escaping.
The hydroponic liquid is created from leaves and water ice.
One of the rare moondusts, the yellow white moondust2 becomes suitable for growing when wet with hydroponic liquid.

The sapling never grew, perhaps it needed dirt or the moonrealm:atmos nodes were blocking it's growth ...
So sod it i'll make my own compact space conifers.

Not sure if this is the problem, but;

Saplings need soil in the groups of the node they are growing on:

Yeah i put soil=1 in the groups, i think it was blocked by moonrealm:air nodes above it.

Version 0.4.1, new screenshots and link in first post.

Moondusts are no longer falling nodes.
Mese blocks and iron ore.
Water ice at high altitudes in moondust and glows gently in the moonlight (light source = 1).
Water ice can be crafted to default:water_source.
Moonstone brick and moonstone slab.
Lux crystals are defined as a fuel with a longer burntime than coal.
Moonstone can be crafted into default:furnace.
Moonglass cooked from the light grey moondust1.
Life support air nodes that spread by abm, replacing tinted atmosphere and default "air" but do not pass through thick walls (beware diagonal leaks, a single leak can spread out of control and cause abm meltdown).
Life support air generators add nodes around itself when placed.
Airlock nodes with illumination.
Hydroponic liquid crafted from old leaves and water ice, slightly more viscous than water.
Only the white moondust5 is suitable as hydroponic bedding, hydroponic liquid 'source' or 'flowing' will saturate neighbouring moondust5 nodes turning them into moonsoil, in this you can plant a space pine sapling, this will only grow when planted in moonsoil beneath either "air" or "moonrealm:air".
Removing hydroponic liquid will cause moonsoil to dry out and revert to moondust5.
Space pines are specially bred compact evergreens for oxygen regeneration and general cool vibage.

real? it's as real as this one :p

Too complicated, i'd have to start over with all-oss mods, and it wouldn't be half as pretty (or functional) :/

I could but i'm not interested, someone else can do that :) It would be easier if Dopium or someone else forked this mod, changed the textures to differing shades of grey, and inserted the portal code.

Completely forgot to say ... from version 0.3.0 i have been using 2 3Dperlin noises added for terrain generation, their scales are in the golden ratio 1.618, this is the most irrational number so the scales stay out of phase over large distances, in terms of music this would be 2 tones forming a very dissonant interval, the idea is to break up any obvious scale to the terrain and try to create very large scale interference patterns between the 2 perlin noises.
Doing this actually 'rounds off' the rougher more mad terrain features so i have had to increase the persistence a little to compensate.

Next ... lakes. For example Titan has lakes of hydrocarbons, i get to make another new liquid in another funky colour B)

Perhaps I could add stuff to my nanotech (carbon fibre) mod to do with this... If you have any ideas for a carbon composite extraterrestrial-base part it would be awesome!

This mod would make an awesome base for a mystcraft-like minetest mod ;-)

In the meantime im gonna try the latest and build a rig ontop of those lakes :-)

Mauvebic: I am currently doing something like that, but it is not very developped yet. You can still try it at https://github.com/Novatux/realms
