Module:BuildingStats
Documentation for this module may be created at Module:BuildingStats/doc
-- Renders building statistics from [[Module:Data/Buildings]].
--
-- This module is hand-written, in the same style as Module:UnitStats.
-- Module:Data/Buildings is meant to be generated by scripts/export-wiki-data.cjs
-- (which only writes under the Module:Data/ prefix), so this file is never
-- overwritten by the export.
--
-- Entry points:
-- infobox - stat box for ONE level {{#invoke:BuildingStats|infobox|code=metal_mine|level=1}}
-- levels - comparison table, ALL levels {{#invoke:BuildingStats|levels|code=metal_mine}}
--
-- Expected shape of Module:Data/Buildings (field names follow the game's
-- building tier table: resource_output, unit_efficiency, maintenance_cost,
-- build_time, required_<resource>, upkeep_<resource>):
--
-- return {
-- metal_mine = {
-- name = 'Metal Mine',
-- kind = 'Resource Production', -- optional
-- produces = 'metal', -- optional, resource code
-- trains = 'Infantry', -- optional, free text
-- max_level = 5, -- optional
-- levels = {
-- [1] = {
-- output = 50, -- resource_output, per hour
-- efficiency = 1.0, -- unit_efficiency
-- maintenance = 10, -- maintenance_cost
-- build_time = '1h',
-- cost = { money = 100, metal = 0, concrete = 20, petrol = 0, uranium = 0 },
-- upkeep = { metal = 0, concrete = 0, petrol = 0, uranium = 0 },
-- },
-- [2] = { ... },
