[R]

Name of this technology.


[R]

Localised name of this technology.



[R]

The prototype of this technology.


:: boolean
[RW]

Can this technology be researched?


:: boolean
[RW]

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


:: boolean
[R]

Is this an upgrade-type research?


:: boolean
[RW]

Has this technology been researched?


:: dictionary[stringLuaTechnology]

Methods

reload()

Reload this technology from its prototype.


help() → string

Return values

:: string

Attributes

force :: LuaForce [Read]

The force this technology belongs to.


name :: string [Read]

Name of this technology.


localised_name :: LocalisedString [Read]

Localised name of this technology.


localised_description :: LocalisedString [Read]


prototype :: LuaTechnologyPrototype [Read]

The prototype of this technology.


enabled :: boolean [Read/Write]

Can this technology be researched?


visible_when_disabled :: boolean [Read/Write]

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


upgrade :: boolean [Read]

Is this an upgrade-type research?


researched :: boolean [Read/Write]

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 :: dictionary[stringLuaTechnology] [Read]

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


research_unit_ingredients :: array[Ingredient] [Read]

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


effects :: array[TechnologyModifier] [Read]

Effects applied when this technology is researched.


research_unit_count :: uint [Read]

The number of research units required for this technology.

Note

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


research_unit_energy :: double [Read]

Amount of energy required to finish a unit of research.


order :: string [Read]

Order string for this prototype.


level :: uint [Read/Write]

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 :: string [Read]

The count formula used for this infinite research or nil if this isn't an infinite research.


valid :: boolean [Read]

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 :: string [Read]

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.
