LuaTechnology

One research item.

Attributes

force

• Read: LuaForce
• Write: unknown
• Optional: false

The force this technology belongs to.

name

• Read: string
• Write: unknown
• Optional: false

Name of this technology.

localised_name

• Read: LocalisedString
• Write: unknown
• Optional: false

Localised name of this technology.

localised_description

• Read: LocalisedString
• Write: unknown
• Optional: false

prototype

• Read: LuaTechnologyPrototype
• Write: unknown
• Optional: false

The prototype of this technology.

enabled

• Read: boolean
• Write: boolean
• Optional: false

Can this technology be researched?

visible_when_disabled

• Read: boolean
• Write: boolean
• Optional: false

If this technology will be visible in the research GUI even though it is disabled.

upgrade

• Read: boolean
• Write: unknown
• Optional: false

Is this an upgrade-type research?

researched

• Read: boolean
• Write: boolean
• Optional: false

Has this technology been researched? Switching from false to true will trigger the technology advancement perks; switching from true to false will reverse them.

prerequisites

• Read: Dict<string, LuaTechnology>
• Write: unknown
• Optional: false

Prerequisites of this technology. The result maps technology name to the LuaTechnology object.

successors

• Read: Dict<string, LuaTechnology>
• Write: unknown
• Optional: false

Successors of this technology, i.e. technologies which have this technology as a prerequisite.

research_unit_ingredients

• Read: Array<ResearchIngredient>
• Write: unknown
• Optional: false

The types of ingredients that labs will require to research this technology.

research_unit_count

• Read: uint32
• Write: unknown
• Optional: false

The number of research units required for this technology.

This is multiplied by the current research cost multiplier, unless LuaTechnologyPrototype::ignore_tech_cost_multiplier is true.

research_unit_energy

• Read: double
• Write: unknown
• Optional: false

Amount of energy required to finish a unit of research.

order

• Read: string
• Write: unknown
• Optional: false

The string used to alphabetically sort these prototypes. It is a simple string that has no additional semantic meaning.

level

• Read: uint32
• Write: uint32
• Optional: false

The current level of this technology. For level-based technology writing to this is the same as researching the technology to the previous level. Writing the level will set LuaTechnology::enabled to true.

research_unit_count_formula

• Read: MathExpression
• Write: unknown
• Optional: true

The count formula, if this research has any. See TechnologyUnit::count_formula for details.

saved_progress

• Read: double
• Write: double
• Optional: false

Saved technology progress fraction as a value in range [0, 1). 0 means there is no saved progress.

valid

• Read: boolean
• Write: unknown
• Optional: false

Is this object valid? This Lua object holds a reference to an object within the game engine. It is possible that the game-engine object is removed whilst a mod still holds the corresponding Lua object. If that happens, the object becomes invalid, i.e. this attribute will be false. Mods are advised to check for object validity if any change to the game state might have occurred between the creation of the Lua object and its access.

object_name

• Read: string
• Write: unknown
• Optional: false

The class name of this object. Available even when valid is false. For LuaStruct objects it may also be suffixed with a dotted path to a member of the struct.
