Types/MapGenPreset

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: MapGenSettings

All properties can be omitted. If not set they will just use the default values. seed is ignored for a map gen preset.

terrain_segmentation

Type: Types/MapGenSize

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.

water

Type: Types/MapGenSize

Shown as water coverage in the map generator GUI.

default_enable_all_autoplace_controls

Type: Types/bool

Default: true

If this is false, then all autoplace controls will be disabled.

autoplace_controls

Type: Types/table

Table of Data.raw#autoplace-control name keys mapped to table values. Each table can have the following fields:

• frequency - Types/MapGenSize
• size - Types/MapGenSize
• richness - Types/MapGenSize

Example:

autoplace_controls =
  {
    ["iron-ore"] = { richness = 2, size = 0.5, frequency=2},
    ["enemy-base"] = { size = 1},
    ["trees"] = { richness = 4}
  }

autoplace_settings

Type: Types/table

property_expression_names

Type: Types/table

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.

starting_points

Type: Types/table of Types/Position

Array of the positions of the starting areas.

seed

Type: Types/uint32

Read by the game, but not used or set in the GUI.

width

Type: Types/uint32

height

Type: Types/uint32

starting_area

Type: Types/MapGenSize

Size of the starting area. The starting area only effects enemy placement, and has no effect on resources.

peaceful_mode

Type: Types/bool

cliff_settings

Type: CliffPlacementSettings

advanced_settings

Type: Types/table

All properties can be omitted, if not set they will just use the existing values.
