Basics

A map gen preset. Used in Prototype/MapGenPresets.

Mandatory properties

order

Type: Types/Order

Specifies the ordering in the map generator gui.

Optional properties

default

Type: Types/bool

Default: true

Whether this is the default preset. If set to true, this preset may not have any other properties besides this and order.

basic_settings

Type: Types/table

This is a table with the below key/value pairs. All key/value pairs are optional. If not set they will just use the default values.

This is the inverse of "water scale" in the map generator GUI. So a water scale that shows as 50% in the GUI is a value of 1/0.5 = 2 for terrain_segmentation.
Shown as water coverage in the map generator GUI.
  • default_enable_all_autoplace_controls - Types/bool - Default: true
Whether undefined autoplace_controls should fall back to the default controls or not.
Table of Data.raw#autoplace-control name keys mapped to table values. Each table can have the following fields:
Example:
autoplace_controls =
  {
    ["iron-ore"] = { richness = 2, size = 0.5, frequency=2},
    ["enemy-base"] = { size = 1},
    ["trees"] = { richness = 4}
  }
Each setting in this table maps the string type to the settings for that type. Valid types are "entity", "tile" and "decorative".
Map of property name (e.g. "elevation") to name of noise expression that will provide it. Entries may be omitted. A notable usage is changing autoplace behavior of an entity based on the preset, which cannot be read from a noise expression.
Array of the positions of the starting areas.
Read by the game, but not used or set in the GUI.
Amount of tiles from left to right. Silently limited to 2,000,000, +/- 1 million tiles from the center.
Amount of tiles from top to bottom. Silently limited to 2,000,000, +/- 1 million tiles from the center.
Size of the starting area. The starting area only effects enemy placement, and has no effect on resources.
