Please report any bug, or suggest new biome!

These 8 screenshots are of the amgmt mapgen. It looks like you look up to paramat, considering the fissures that I saw.

The screenshots were taken in cg72's fork of Minetest (MineTime.) It can be found on GitHub.

Have you considered adding support for the following mods to your amgmt mapgen?
moreores
technic
darkage
moretrees
plantlife
They won't generate anything in the worlds created by the mapgen if they are not supported. By the way, have you ever used those mods?

Nice screenshot, Thanks!

Yes, many kind of code I use for this mod. Thanks paramat!

I don't know about that. But, thanks to tell me.

I will try. By the way, I never use that mods. :D

Thats like a Biomes-Mod! Here is the Biomes-Mod: https://forum.minetest.net/viewtopic.php?f=11&t=9331&hilit=biomes#p142510

[Krock]

Here is the Biomes-Mod:

That's a complete Lua mapgen - biomes are almost a must-have.
---

Why do you generate bedrock two times?
Also, I found some parts in the codes which have potential to become better:

+ Spoiler

https://github.com/srifqi/amgmt/blob/master/init.lua#L1

Code: Select all

amgmt = amgmt or {}

amgmt is not defined before, so simply set it to {}, instead of checking

https://github.com/srifqi/amgmt/blob/ma ... it.lua#L29

Code: Select all

local sidelen = maxp.x - minp.x +1

better add a side length param in the function instead of calculating it every time.

https://github.com/srifqi/amgmt/blob/ma ... t.lua#L151

Code: Select all

data[vi] = c_air

It is air by default in singlenode, no needs to set it again to air.

https://github.com/srifqi/amgmt/blob/ma ... t.lua#L215

Code: Select all

local nizx = cz*chulen*16 + cx*16

nizx is already defined above, an easier readable soulation would be

Code: Select all

nizx = (cz * chulen + cx) * 16

Little changes - but they make the codes better readable

It contains some very interesting terraforming functions, I like it.

Really? I just try to create a lua mapgen like Experimental mapgen[mg]

biomes are almost a must-have.

Agreed.

Compability for nether mod.
EDIT: It never get compatible.
Nothing. See last update.

Thanks, for suggestion!

Thanks! I will add some space near river that cut through terrain.

UPDATE 0.2!
Changes:

• A better cave. Rename old 'cave' to fissure.
• Make just only one global variable: 'amgmt'
• Fix caving system (new shape!)
• Terraforming update (1): Better cave generation. 2 cave system. More common lakes.
• Terraforming update (2): Add some space near river that cut through terrain. Applying Krock's suggestion.

UPDATE 0.3! (Decoration update)
Changes:

• Change num_ore_per_clust param to ore_per_clust. Add moreores compability. Bugfix.
• Big update (1):
  
  • Add 'Swampland' biome.
  • More common cave.
  • 'Cutted tree' bugfix.
  • Add 'amgmt_regenerate' to regenerate map chunk.
  • Add 'amgmt_fixlight' to fix lighting.
  • Add Savanna and Pine sapling, tree, leaves, and wood.
  • Experimenting with minetest.register_ore.

UPDATE 0.3.1! (Performance Update)
Changes:

• Fissure changed to minetest.get_perlin_map from minetest.get_perlin.
• Less cave (from 10 to 5).
• 200% faster.

Three bad things I found:
- Map generation takes too long (actually, no wonder with 16 perlin noises)
- Console/log gets spammed
- The group "leafdecay" removes the leaves of all trees in the subgame "base_game". This would solve it:

Code: Select all

      description = tree_add[i][2].." Leaves",
+      trunk = "amgmt:"..tree_add[i][1].."_tree",
      drawtype = "allfaces_optional",

But else - the terrain looks nice.

What's that?

What should I remove?
2 noise for height
1 noise for fissure
2 noise for temperature and humidity
1 noise for experimental water lake
5 noise for caves
5 noise for cave deepness
I think, you will remove 8 noise for caves and it's deepness.

- Console/log gets spammed

Set DEBUG param to false. I shall change the default to false.

Will be changed in next update. Thanks!

Thanks! I'm experimenting with plateau.

Experimental water lakes! (I should update this. Maybe i'll used paramat's highlandpools' code)

[paramat]

Highlandpools is very slow, and designed to add to core mapgens. With a lua mapgen it's much faster to use a different method.

Then, how? Any ideas?

[paramat]

I'm thinking ... instead of searching for a natural depression in the terrain, create one with 2D noise, then fill with water but only up to a level that doesn't overflow, should be fast. I need to dot this in 'fracture' mod so we can have water pools in floatlands.

This mod has 2d noise for lake already.

Cool!

UPDATE 0.4! (Terraforming update (2))
Changes:

• Biome temperature and humidity update.
• Simplified height calculations
• Remove fissure
• Add plateau.
• Less noise.
• Leafdecay bugfix.
• Better ore generation.
  
  
  

Sorry, no screenshot for now!

Nice. (Generation time: 2600ms)


And the fake (reproduced within 10 minutes) canyon in my mapgen: (Generation time: 800ms)


Does your mapgen support minetest.register_ore() or is a special function needed?

I'm still experimenting with it.

I'm still thinking how to do this.

[SAMIAMNOT]

So what biomes are there? Is there a snow and ice biome?
I love the idea of canyons.

[Baggypants]

I love this mod. More of this sort of thing. Although the small lakes appear on the land, underwater and floating in the sky.

[srifqi]

UPDATE 0.5! (Mineshaft update)
Changes:

• Add new biome: Cold Mesa and Mesa
• Add .clear() method to amgmt.biome, amgmt.tree, amgmt.ore
• Add bakedclay support (Thanks, TenPlus1!)
• Mineshaft feature added
• Better lake spawn algorithm
