Depends default

This mod selects auto singlenode mapgen.
Edit the parameters at the top of the init.lua to choose your realm shape, and to set realm size and location.

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 flat = false -- Normal flat realm
local vertical = false -- Vertical flat realm facing south
local invert = false -- Inverted flat realm
local planet = false -- Planet sphere
local dysonsphere = false -- Dyson sphere
local tube = false -- East-West tube world / O'Neill space colony
local cube = false -- Planet cube
local dysoncube = true -- Dyson cube

^ Cross section of dyson sphere.

The world I live in is a lie.

[RealBadAngel]

that what you do is simply amazing

[Inocudom]

This mod appears to make the world of Minetest concave. One thing I did notice was that caves above the world were fully lit and did not have shadows.

[paramat]

Version 0.1.3 is at github, new screenshot in first post.
Auto-orientating apple trees and pine trees added. Each tree detects which of the 6 directions has the largest fall in 'density' and grows in that direction.

Thanks Inocudom that was a mistake left in from testing, i had disabled the line:

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

vm:set_lighting({day=0, night=0})

So un-comment that line or better update to version 0.1.3.

[paramat]

Version 0.1.4 at github.
New screenshot in first post.
I added cliffs / faults that show off the sandstone strata.
Perlin noise for terrain is now a mix of 2 similar noises that have their 'spread' or 'scale' distances in the 'golden ratio' 1.618, the intent being to break up any obvious scale to the terrain and the slightly gridlike look of perlin noise from above and in map images.

[Tedypig]

This is cool, but before I download I have a question. Does the world have gravity? Can you walk on the surface the whole way around, or have to hop up the concave?

[paramat]

This question comes up a lot ... Minetest camera orientation and gravity are fixed (as far as i know it would be a major rewrite of the engine, perhaps someone will go on to make a new more universal space-capable game engine with 6 gravity directions).

New version 0.2.0 is at github.
I found and eliminated unnecessary processing, now mostly 2 to 4 seconds per chunk.
I added the temperature / humidity 8 biome system of paragen(v7), but plants and some trees are still missing.
The version at github was pushed in the optional 'flat realm' mode (surface at y = 168), for the original flexy realm enable line 266 and disable line 267.
A 10km radiius dyson sphere is also possible by enabling lines 268, 269 and disabling line 266 (teleport to 0, 5000, 0).

Since a day ago there has been a 3 noise terrain shape, with a blend of rough and smooth areas.

EDIT version 0.2.1 with bugfixes and savanna trees.

[jojoa1997]

Good Job paramat! Keep working on the mapgen/luavoxel/what ever it is you are using and make even more amazing mods.

[rubenwardy]

This is pretty awesome.

[paramat]

Version 0.2.2 is at github.
Jungletrees added.

[philipbenr]

Perfect. What I was waiting for. :) +1 on your work so far paramat.

[paramat]

Version 0.2.3 now at github.
Now 5 realm types, added vertical and inverted, select by editing the true/false parameters.

[paramat]

Version 0.2.4.
Non-flowing water (range = 0,) so no more invisible nodes holding back the water and also preventing building or papyrus near water. Also you can now enable cavegen without the threat of vast buggy waterfalls everywhere.
Tree direction is now auto-set per realm type ... although i have just realised a mistake in that for dyson sphere ... fix commit coming soon *:/

*** EDIT
Until then fix is edit line 402 to this:

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 tree then
    if flat or sphere then
    treedir = 3

Of course this is only correct for the lowest quarter of the dyson sphere.

[paramat]

Version 0.2.5.

[paramat]

Version 0.2.6.
Oops my mistake, 'liquid_range = 0' water sources were spreading due to 'liquid_renewable = true'.
So now back to non-flowing water, no airlike nodes, no need to disable cavegen.

[paramat]

Version 0.2.8.
Grasses added to deciduous forest, savanna and grasslands.
Optional hollow cylinder and planet-sphere realms.
Optimised lua code.
Rivers added, water becomes glacier flow in cold biomes.

[philipbenr]

Holy crud. A lot of release. Oh well, I suppose I'll have to get the latest.

[paramat]

Version 0.2.9
Rivers completed, new noise parameters for smoother terrain and rivers, 2 realms now renamed 'dyson' and 'tube'. Optional default water for the flat realm. Fixed fissure sand.

Version 0.2.10
Bugfixes. Auto-orientating trees for add realms. Mod's own dirt to avoid dirt changing to green grass in dry grass biomes.

Version 0.2.11
Sandline variation, dunes with dry grasses, swampwater with papyrus ... :P

0_o Crud. Not again. Oh well. I'll wait for about 1 or 2 more updates. ;)

[paramat]

^ lol

Version 0.2.12
Tune swamps, range 3 water, dry rivers in deserts.

[paramat]

Version 0.2.13. Solstice greetings ...
3 heights of grass are in deciduous forest and wet grassland.
In the deciduous forest 6 flowers and clay in shallow water.

[paramat]

Version 0.2.14
Added some WIP non-flowing lava in the fissures that rises to the surface in rough terrain.
Added a layer of non-falling gravel as a strata layer in stone, it drops default:gravel.
Added more interesting shaped cacti on the savanna edge of deserts.
Bugfixes.

flexrealm 0.2.14 by paramat
For latest stable Minetest and back to 0.4.8
Depends default
Licenses: code WTFPL, textures CC BY-SA

Uses LVM ... chunk generation time is roughly 4 seconds.
Edit the parameters at the top of the init.lua to choose your realm shape, and to set realm size and location.

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 flex = false -- 3D noise flexy realm
local flat = true -- Normal flat realm
local vertical = false -- Vertical flat realm facing south
local invert = false -- Inverted flat realm
local dyson = false -- Dyson sphere
local planet = false -- Planet sphere
local tube = false -- East-West tube world

By default a flat realm with range = 3 water is created, for other realms the option of non-flowing water is recommended.
The lighting option is useful for realm testing or avoiding extreme shadows caused by some of the realm shapes.

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 light = false -- Layer of light emitting airlike nodes following terrain
local noflow = false -- Use no-flow water to avoid massive waterfalls

flexrealm is continuous across all intersections with multiple copies of itself, as in the 'dysoncube' modpack: terrain, biomes, lakes, cliffs and rivers are all defined by 3D noise which is continuous through all space.
So you can have multiple versions of this mod that are different realm shapes, they will blend at the intersections.
