how do you add ores and biomes

[Christian9]

ive seen mods do it but i dont know how

[Krock]

You can't add biomes in mgv6 but mgv5/7 allow the register_biome function

For ores, see http://dev.minetest.net/minetest.register_ore .

Just look at their code.

Ores are added with minetest.register_ore:

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.register_ore({
      ore_type       = "scatter",
      ore            = "default:stone_with_gold",
      wherein        = "default:stone",
      clust_scarcity = 15*15*15,
      clust_num_ores = 3,
      clust_size     = 2,
      y_min          = -255,
      y_max          = -64,
      flags          = "absheight",
   })


As for biomes, you probably want to clear existing biome definitions first:

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

-- Clear mgv5/mgv7 biomes and decorations
minetest.clear_registered_biomes()
minetest.clear_registered_decorations()

Then look at the bottom of this file: https://github.com/paramat/paragenv7/bl ... r/init.lua

Note that only v5 and v7 map generations support proper biomes, in v6 biomes are a hack (you basically overwrite the already-present biomes).

In other words, at least you aren't alone. NOBODY knows what they are, what they do, or how you use them. Proven by the sparsity of examples and documentation (including the forums, the developer wiki, and lua_api.txt). For now, probably better just to roll your own using noise in Lua, interpret it, and splat the results in using VoxelManip. I'm sure it's slower than the nebulous thing nobody can describe at doing whatever it is it does, but....

Don't make your own system to do the same thing.

I don't think biomes are officially supported yet (they weren't last time i checked) but jordach made a nice tutorial on them. See the Dropbox link in his signature.

Ah. Yeah. Sorry. I should have qualified that. I was mostly referring to biomes. Ores are a little better documented at this point.

Of course, I'd be happy to be proven wrong about there being some documentation on biomes somewhere (I'd even be happy to—with permission and any caveats about lack of official support—help copy it to the developer wiki). However, there don't seem to be any links in Jordach's signature at the moment, so such documentation still has yet to materialize.

Another possibility is to take a look at recent "register_biome" activity on github. See what others are doing.

Cool. I see it may be a bit, "opinionated," too. Should be a good read. Thank you.
