[Mod] Mountain ranges [0.4.5] [landup]

[paramat]

This is good mod, but there are a few things that bug me:

1.) Most importantly the mountains are way too steep. It takes forever to climb up them and trying to climb down them with damage turned on is suicidal. I think the steepest (near vertical) walls should spaced out more or reserved for only the highest peaks.

2.) There are often huge cube shaped (over 100 meters) long areas carved out of the mountain ranges as if the mod decided to start rendering something else in the middle of it's work. These areas have completely smooth walls with no signs of erosion, dirt, grss, or trees. This detracts from the immersion factor of having a beautiful world to play in.

3.) When the land gets streched upwards it also stretches the ore deposites leading to very long vertical lines of ore.

All of this is happening with version 0.4.5 of minetest on version 0.3.0 of the mod.

Keep up the fine work,

Thanks :)
1. You can make the mountain ranges wider, more natural and less steep by using a wider noise range: NOISEL = -0.3 NOISEH = 0.3. However this will increase generation time.
2. You may need to increase EXPSEC to 5 or 6 seconds or so if the spiral teleportation doesn't seem to be generating all the upper chunks as it should. Ungenerated upper chunks causes those missing blocks. Also increasing MAXUP beyond 160 may cause this.

I have made the code to remove those terrain bugs:

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

local landup_filename=minetest.get_worldpath() .. "/landup"

local function read_file()
    local f = io.open(landup_filename, "r")
    if f==nil then return {{},{}} end
        local t = f:read("*all")
        f:close()
    if t=="" or t==nil then return {{},{}} end
    return minetest.deserialize(t)
end

local function write_file(tbl)
    local f = io.open(landup_filename, "w")
        f:write(minetest.serialize(tbl))
        f:close()
end

local rf=read_file()
local chunks_to_load = rf[1]
local nodes_to_add = rf[2]
if chunks_to_load == nil then chunks_to_load={} end
if nodes_to_add == nil then nodes_to_add={} end


minetest.register_on_shutdown(function()
    write_file({chunks_to_load,nodes_to_add})
end)

local time_wait=0

minetest.register_globalstep(function(dtime)
    local env=minetest.env
    time_wait=dtime+time_wait
    if time_wait>2 then
        time_wait=0
        --if chunks_to_load~={} then print(dump(chunks_to_load)) end
        nchunks_to_load={}
        local ci=1
        for _,chunk in ipairs(chunks_to_load) do
            if minetest.env:get_node_or_nil({x=chunk.x*16,y=chunk.y*16,z=chunk.z*16}) ~= nil then
                print(dump(chunk))
                nnodes_to_add={}
                local i=1
                for _,node in ipairs(nodes_to_add) do
                    if math.floor(node.pos.x/16)==chunk.x and
                        math.floor(node.pos.y/16)==chunk.y and
                        math.floor(node.pos.z/16)==chunk.z then
                        env:add_node(node.pos,node.node)
                    else
                        nnodes_to_add[i]=node
                        i=i+1
                    end
                end
                nodes_to_add=nnodes_to_add
            else
                nchunks_to_load[ci]=chunk
                ci=ci+1
            end
        end
        chunks_to_load=nchunks_to_load
    end
end)

local function add_node_later(pos,node)
    local chunk={x=math.floor(pos.x/16),y=math.floor(pos.y/16),z=math.floor(pos.z/16)}
    nodes_to_add[#nodes_to_add+1]={pos=pos,node=node}
    for _,chk in ipairs(chunks_to_load) do
        if chk.x==chunk.x and chk.y==chunk.y and chk.z==chunk.z then return end
    end
    chunks_to_load[#chunks_to_load+1]=chunk
end

local function safe_add_node(pos,node)
    local env=minetest.env
    if env:get_node_or_nil(pos)==nil then
        add_node_later(pos,node)
        return
    end
    env:add_node(pos,node)
end


Add that at the beginning of the code, and replace env:add_node everywhere else with safe_add_node, and there is no bug after that.

Here is a screenshot:


Sometimes, you can think that a chunk has not been generated, but if you wait a bit, it will appear.

That's awesome Nore, thanks :) good screenshot too.

I'm busy with other projects but i intend to test this and hopefully include it in a new version.

[proller]

another way to make higher mountains:
mgv6_np_terrain_base = -4, 200, (250, 250, 250), 82341, 5, 0.6
mgv6_np_terrain_higher = 20, 160, (500, 500, 500), 85039, 5, 0.6

Version 0.4.0
New screenshot in first post.
Lua voxel manipulator / perlin map rewrite, chunk processing time roughly 1 second.

I made a new world with this mod enabled and couldn't find any evidence of the mod. My doubts built up and I was thinking "what a scam" until I nearly fell into this:


Great mod!

I don't think that has anything to do with the mod... To find the mountain ranges, you need to just walk/fly around... They can be quite rare.

[paramat]

Yes im not sure that's part of my mod, the mountain ranges are roughly separated by 4000 nodes so you may need to travel that far or more to find them.

[HATEandPAIN]

wooooooooow

[paramat]

Version 0.4.3 with new parameters, pines above y = 47, pinewood and pine saplings.

[paramat]

Screenshot removed.

[paramat]

0.4.5
Mod's own snowblocks to avoid cavegen griefing.
Snow now deepens with height above snowline using the same method as the thinning soil/sand.

Stuff i need to do: ores and caves/tunnels/fissures

[Johnny Joy]

Would it be possible to use something like ethereal with landup?

[Gael de Sailly]

I've found a big problem.

It doesn't generate water, and it doesn't generate any block below y = -32. I've briefly watched the code and I have not found the bug.

But the mapgen looks good, I like the mountains generated both with 2D and 3D noises.

[paramat]

Johnny Joy, it willl work in any mapgen, but the biomes will not match anything other than mgv6.

Gael de Sailly, this is for use in mgv6, it just adds mountain ridges to what's already there.

I didn't understand it that way.

[JoshMars]

So... do pinelings grow?

[paramat]

Currently pine saplings grow only between y = 48 and y = 127, as if that was their natural habitat.

Thanks... I was wondering:)
