Properties

icons :: array[IconData] optional

Can't be an empty array.

icon :: FileName optional

Path to the icon file.

Only loaded, and mandatory if icons is not defined.

icon_size :: SpriteSizeType optional

Default: 64

The size of the square icon, in pixels. E.g. 32 for a 32px by 32px icon. Must be larger than 0.

The base game uses 256px icons for technologies.

Only loaded if icons is not defined.

upgrade :: boolean optional

Default: false

When set to true, and the technology contains several levels, only the relevant one is displayed in the technology screen.

Example

{
  type = "technology",
  name = "physical-projectile-damage-2",
  [...]
  upgrade = true
}

enabled :: boolean optional

Default: true

essential :: boolean optional

Default: false

Whether the technology should be shown in the technology tree GUI when "Show only essential technologies" is enabled.

visible_when_disabled :: boolean optional

Default: false

Controls whether the technology is shown in the tech GUI when it is not enabled.

ignore_tech_cost_multiplier :: boolean optional

Default: false

Controls whether the technology cost ignores the tech cost multiplier set in the DifficultySettings. E.g. 4 for the default expensive difficulty.

allows_productivity :: boolean optional

Default: true

research_trigger :: TechnologyTrigger optional

Mandatory if unit is not defined.

unit :: TechnologyUnit optional

Determines the cost in items and time of the technology.

Mandatory if research_trigger is not defined.

max_level :: uint32 or `"infinite"` optional

"infinite" for infinite technologies, otherwise uint32.

Defaults to the same level as the technology, which is 0 for non-upgrades, and the level of the upgrade for upgrades.

prerequisites :: array[TechnologyID] optional

List of technologies needed to be researched before this one can be researched.

Example

prerequisites = {"explosives", "military-2"}

show_levels_info :: boolean optional

Can be used to enable or disable showing levels info in technology slot.

effects :: array[Modifier] optional

List of effects of the technology (applied when the technology is researched).

Example

{
  {
    type  = "unlock-recipe",
    recipe = "land-mine"
  }
}

Overridden Properties

name :: string

If this name ends with -<number>, that number is ignored for localization purposes. E.g. if the name is technology-3, the game looks for the technology-name.technology localization. The technology tree will also show the number on the technology icon.

hidden :: boolean optional

Default: false

Hides the technology from the tech screen.

Example

{
  type = "technology",
  name = "steel-processing",
  icon_size = 256,
  icon = "__base__/graphics/technology/steel-processing.png",
  effects =
  {
    {
      type = "unlock-recipe",
      recipe = "steel-plate"
    },
    {
      type = "unlock-recipe",
      recipe = "steel-chest"
    }
  },
  unit =
  {
    count = 50,
    ingredients = {{"automation-science-pack", 1}},
    time = 5
  },
  order = "c-a"
}
