Restore mapgen v5 ?

by Gael de Sailly » Post

Hello !

I suggest to restore the mapgen V5 in the following Minetest version. It was interesting, because it was 3D noise.
I found these landscapes has a somewhat wonderful thing. I've played many times in the same world. But I had the bad idea to continue playing on it with Minetest 0.4.8 last year, and with mods, for example my Forest mod, carts and animal_modpack. Now I have a foolish map. But I've preserved the seed.

If I want to restaure this code, it's not only for me, but by thinking about this world, and this mapgen, I've realized it was actually very interesting.

The better place which remains of my world : this mountain has 94 blocks height. It doesn't exist in mapgen v6.

There are 2 ways to do it :

First, we can translate it in LUA by lua voxelmanipulator and publish it as a mod.
Or we can put it in default mapgens (like v6, v7, indev and math) for the following Minetest.

I haven't a very good knowleadge of the C++. I think I can do the first thing, but not the second.
The code can be found here.

What do you think about it ?
Just realize how bored we would be if the world was perfect.

The people from FM already added it back to the game (or planned to do so)
I would like to have this mapgen again in the game :)

Celeron55 wants v5 back in Minetest, and a while back stated he wants to do that himself, whether he will get around to it i'm not sure. I recently considered making a simplified lua version. For a c++ version we could add mgv6 caves and biomes, mudflow etc. to mgv5 (because mgv7 has no biomes), so could be quite simple. If i can get my head around c++ mapgen i might have a go myself.

Have you ever seen the caves in a mapgen v5 world? They are quite interesting.

Oops i forgot, caves are done in a better way in mgv5, using 2 3D noises, so this should be conserved for sure.

Yes, sure, I prefer this cave generator. For example I've found a big cave which make the link between a beach and a mountain. It doesn't exists in v6 or it's far fewer beautiful.

I fully support the idea of reviving MGV5.

I already suggest this in the ''News'' section, but only as a comment; glad to see that other people also think like me.

I agree as well, v6 is quite dull in mapgen wise, nothing really to explore. and v7 the only way to use it is add a mod and a lot of lag :(

See https://github.com/minetest/minetest/is ... t-58321246 for Celeron55's almost complete mgv5 for recent Minetest, i edited his commits a little for latest Minetest and now have mgv5 running in a local compiled version. I might put my commits up at Github so you can compile this into Minetest yourself.
Hopefully i can get default registered ores working in this, hmmmm wants the mgv7 biome API used so i might attempt to integrate that.

That has been my experience so far. I have been unimpressed with the caving experience. All I have seen are moderately sized pocket caverns, no tunnels at all. :(

^ Mgv5 in 0.4.10-dev from Celeron55's fork.
I added ores, removed the biomes. While i learn how to add the mgv7 biome API i'm using 'paragenv7' mod to add biomes (roughly 600ms per chunk). To use mgv7 you have to add your own biome and decoration registrations, see the 'Big Freaking Dig' Game as an example, using the mgv7 biome API this way is not slow because it is C++.

Here's my mgv5 branch https://github.com/paramat/minetest/tree/mgv5
Here's the commit that adds mgv5 to recent 0.4.10 https://github.com/paramat/minetest/com ... f9654b2748
If you compile this you can use stone-only mgv5 with paragenv7.

I tried, but I must have botched it somewhere as I have no v5 option. Cloned your repo, cmake, make yada yada, and got vanilla minetest. hmmm guess I'll try again.

Maybe you forgot to switch to the mgv5 branch ?
=> git checkout -b mgv5

I just now managed to get the mgv7 biome API working in mgv5.

I will be sure to tell the developers of Freeminer about this.

Thank You! Not forgot, didn't know, I'm a noob. Got it compiled now and just spent some time flying around some maps. I see what you guys mean, much more interesting maps, saw some great fjords. Some of it gets a bit surreal, but it does so in an eye-pleasing way as opposed to downright ugly like often happens for me in v6.

v6 isn't ugly so to say, but more plain you can go server to server that runs v6 and see not much difference in the two. that is why I love the idea of v5 being readded.

Try running BFD. I'd like to see MGV5 with something that actually can use the Biome API.

Yes, mapgen V5 is slower. But if you have a recent computer, it's not a problem.

mgv5 can't be very slow because several Lua mapgen use 3d perlin noise without long generation times.
