Anyone know how to make specific map seeds?

I think not, the world is causally generated

I'm pretty sure the map seed is displayed with the debug text
Keep calm and code python^_^

See your world dir's map_meta.txt, the seed is there.

You can create a new world with a custom numerical seed by editing "/world/map_meta.txt" and removing the current "map.sqlite" file in the same directory.
Not here for a while due to some troubles between my graphic card and Minetest.

If you always want the same map seed, or don't mind editing your minetest.conf a lot, you can specify "fixed_map_seed = (whatever)" in your minetest.conf.

not sure but as far as i can tell map seeds are normally very long and complicated (but then again i have no clue how to work with the .conf file or hardly any files for that matter xD)


if your wanting a specific map (alot of oceans,or land, or high plateus) then you need to either get very very lucky in generation of a map (or hunt for a spot within its 31k blocks in ea direction) or you can request a mod for it...i think someone is making/has made a mod where the map is just flat plains all over but i dont know where its at or if its done
I like to debate.

I know about the flatlands mod.

There was a thing online where you type your map seed in and it shows the coordinates of all nyancat bricks.

Awesome!


I always do search for a seed for a lone island.
Has anyone found one?

Anyone know any seeds that make a good world for builds? I need seed and version. (V5, V6, V7, Fractal, Valleys)

I had started a Map-Database on the wiki,
with currently only a few entries.

Feedback welcome !

You can't rely on mapseeds alone to determine whether a world is suitable for building, mining, etc..The perlin noise parameters are far more crucial to the map generation algorithm.

For example in mgv7 you can easily produce alien-looking worlds using virtually ANY map seed with only the default perlin noise parameters. Yet with these custom mapgen settings I shared below, you can get far more realistic terrain.

The purpose of a map seed is simply to ensure that the output of the map generation algorithm is unique, not to determine any specific characteristics of that output.

I'll add "and reproducible".

Obviously, this will only work if the settings for the mapgenerator,
biomes etc. are kept the same.

Sadly, it doesn't even guarantee that, at least with mgv7. The algorithm has undergone changes across different versions of Minetest which can effect the integrity of existing worlds with the exact same mapgen settings. I recently commented about this issue in another topic:
