v0.31:World generation

xTATTEREDx  · +FINE+  · *SUPERIOR*  · ≡EXCEPTIONAL≡  · ☼MASTERWORK☼

To begin playing Dwarf Fortress, you must first create a world to play in. At the game's main menu, you can choose to either "Create new world now" or "Design new world with parameters", both options will eventually create an entirely new, randomly generated world.

For information on advanced parameters, see Template:L.

(needs formatting, but this can help determine how to get the terrain types you want)

The World Generator is having trouble placing...

Mountain peaks

rejection log example: Not enough peaks: 1<3 Check your maximum elevation parameters.

• Can the elevation 400 be placed enough times to provide space for your peaks?
  • Check your preset elevations for the elevation 400.
  • You must have at least as many of these highest elevation points as you are requiring peaks.

Alternatively, reduce the number of peaks required by the parameters.

Mid-level elevations.

• Your worldgen parameters must allow elevations between 100 and 299 for this.
  • Check the parameters governing elevation frequencies.
    • Or simply reduce the number of mid-level elevation squares required.

Low elevations

Your worldgen parameters must allow for enough elevations between 0 and 99 for this.

High elevations

Your worldgen parameters must allow for enough elevations between 300 and 400 for this.

Ocean squares along the edges

Your worldgen parameters must allow for enough elevations between 0 and 99 for this.

• If that doesn't work, simply reduce the number of edge oceans required.

rainfall/drainage/savagery/volcanism in the manner specified by the parameters

Check the parameters governing these features. Reduce the number of high, medium or low squares required.

Volcanos

Check your maximum volcanism value.

• Volcanos can only form in areas with 100 volcanism.
  • As such, you must have at least as many areas with 100 volcanism as you do desired volcanos.

If all else fails, reduce the number of volcanos required by the parameters.

Swamps and marshes

Make sure your parameters and presets can support mid-elevation, mid-to-high rainfall, low drainage, non-freezing areas.

• If that doesn't work, reduce the number of swamp squares and regions required by the parameters.

Deserts and badlands

Make sure your parameters and presets can support mid-elevation, very low rainfall, non-freezing areas.

• If that doesn't work, reduce the number of desert squares and regions required by the parameters.

Forests

Make sure your parameters and presets can support mid-elevation, high rainfall, high drainage, non-freezing areas.

• If that doesn't work, reduce the number of forest squares and regions required by the parameters.

Mountains

Make sure your parameters and presets can support high elevation areas.

• If that doesn't work, reduce the number of mountain squares and regions required by the parameters.

Oceans

Make sure your parameters and presets can support low elevation areas.

• If that doesn't work, reduce the number of ocean squares and regions required by the parameters.

Glaciers

Make sure your parameters and presets can support mid-elevation, very high drainage, freezing areas.

• If that doesn't work, reduce the number of glacial squares and regions required by the parameters.

Tundra regions

Make sure your parameters and presets can support mid-elevation, low-to-mid drainage, freezing areas. *If that doesn't work, reduce the number of tundra squares and regions required by the parameters.

Grasslands

Make sure your parameters and presets can support mid-elevation, low-to-mid rainfall, low-to-mid drainage, non-freezing areas.

• If that doesn't work, reduce the number of grassland squares and regions required by the parameters.

Hills

Make sure your parameters and presets can support mid-elevation, low-to-mid rainfall, high drainage, non-freezing areas.

Rivers

Make sure your parameters and presets allow as many mountain squares as you are requiring river start points.

• If that doesn't work, reduce the number of rivers required by the parameters.

Too many subregions

Make sure your parameters and presets aren t so variable that biomes change frequently.

• If that doesn't work, increase the number of subregions permitted by the parameters, up to the cap.

mountain caves

Make sure your parameters and presets allow as many border mountain squares as you are requiring mountain caves.

• If that doesn't work, reduce the number of mountain caves required by the parameters.

Low-lying caves

Make sure your parameters and presets allow as many mid-elevation squares as you are requiring low-lying caves.

• If that doesn't work, reduce the number of non-mountain caves required by the parameters.

civilizations

Make sure your parameters and presets offer enough low-to-mid savagery, evil/good appropriate, biome appropriate squares to establish sites.

• High savagery (66+) blocks civilization placement -- make sure your parameters and presets offer at least small pockets of low-to-mid savagery areas.
  • If you have very few biome types and are placing good or evil regions, they'll often crowd out the civilizations as well.
• If that doesn't work, reduce the number of civilizations required by the parameters.

The world generator couldn t find any civilization definitions

This problem cannot be resolved by continuing, so you should either abort or skip all rejects for a legends-only game.

The world generator is having trouble placing a controllable civilization

Make sure your parameters and presets have adequate squares of this kind.

• Dwarves, for example, require non-evil, non-good, unsavage mountain squares that aren't surrounded by the ocean.
• If that doesn't work, remove the requirement of a controllable civilization from the parameters, which will restrict you to adventurers (assuming an appropriate civilization is placed)
