40d:Pregenerated worlds

In order to rapidly find working worlds and save on generating time, some users pregenerate and share worlds to others. With the new seed technology, it is possible to share an entire world in as little as a dozen digits. Share neat worlds, unique worlds using Seeds to save upload time, or share worlds using the save file to save on world creation time for others.

Since version 0.27.169.33f changed the way world generation works slightly, seeds from earlier versions will generate different worlds. Seeds from those versions are archived at Seed archive.

Downloadable worlds

Downloadable worlds are worlds which have been generated and then compressed into a single archive file for sharing over the internet. Download the file then extract the folder inside the archive into your /data/save folder in order to use it.

Title: fibonacci
Seed: 1123581321
Name: random
Generated under version v0.27.169.33e - intel processor/windowsXP - file included because other machines have had different results with more or less sand/flux
Quick 16 rejects

Map features:
Small 3 by 8 (So good frame rate on older computers)
Magna (obviously)
Sand (top of map)
Flux
Trees (top)
Adamantine (bottom right)
Demon/Eerie glowing pits (bottom right)
Chasm (2 z-levels down in the top of map with iron man and more)
You can add the river by expanding two squares right (those of you with fast machines)

Seeds

Seeded worlds are special "codes" which tell the game's pseudo-random number generator (a sophisticated mathematical function which produces numbers that seem random) where to begin generating a world. Because the random number generator is actually just a mathematical function and thus always produces the same result when given a certain input, you can "seed" the generator to produce an entire series of random numbers on another computer that are exactly the same as they were originally produced on the first computer.

To use a seeded world, select Create a New World during the main menu, then hit s to specify a seed. Type in the seed and hit Enter, then hit Enter one more time to begin generation. It will still take the normal amount of time to generate the world, and you will still have rejects before the world is produced.

The random seed used also determines the world's name if a random name is selected. This disrupts the sequence of psudeorandom numbers. As a consequence, a seed with a player-given name will result in a completely different world than the same seed with a random name. Seed publishers should specify whether a random or a given name was selected when generating the world.

Mineral content is determined at the time it is allocated, (essentially when you dig near it). Accordingly the map seed determines the layers and therefore the probability of certain rocks/ores, but the ore veins themselves will vary.

A further warning: there may be other things that affect world generation, such as your operating system. If you generate a world different from one described here, with the same seed and the same name, please mention it with the relevant details (operating system including any service packs, processor type, and game version) here.

The following seeds were generated with version 0.23.169.33f or later. Seeds for earlier versions are located at the seed archive.
