Module:CollectorsData

--- --- Module for compiling collectors information from wiki data sources. --- Restructures the flat data tables that are produced from CsvUtils to make --- them more conducive to Lua methods that need to display the information.

--- The standard way of using this module is a call like the following: --- --- area = CollectorsData.getCollectorArea(collectorName) --- --- This will return the working radius of the collector. It is preferable to --- call the getter methods with the name of the collector rather than --- retrieving the entire data record for the collector. This way your code --- stays protected from variations in this module. These getter methods are --- called with the plain-language display name of the collector, as spelled --- in the game, including punctuation. --- --- * longDescription = CollectorsData.getCollectorDescription(collectorName) --- * constructionCategory = CollectorsData.getCollectorCategory(collectorName) --- * sizeX, sizeY = CollectorsData.getCollectorSize(collectorName) --- * requiredGoodID, stackSize = CollectorsData.getCollectorRequiredGood(collectorName, requirementIndex) --- * timeSeconds = CollectorsData.getCollectorConstructionTime(collectorName) --- * cityScore = CollectorsData.getCollectorCityScore(collectorName) --- * isMovable = CollectorsData.isCollectorMovable(collectorName) --- * isInitiallyEssential = CollectorsData.isCollectorInitiallyEssential(collectorName) --- * radius = CollectorsData.getCollectorArea(collectorName) --- * storageCapacity = CollectorsData.getCollectorStorage(collectorName) --- * workplaces = CollectorsData.getCollectorNumberOfWorkplaces(collectorName) --- * goodID = CollectorsData.getCollectorRecipeProduct(collectorName, recipeIndex) --- * gradeStars, gatheringSeconds = CollectorsData.getCollectorRecipeStats(collectorName, recipeIndex) --- * iconFilename = CollectorsData.getCollectorIcon(collectorName) --- --- And the following getter methods are all called with the collector's ID. --- You will have an ID instead of a display name when dealing with other data --- like recipes, species, etc. --- --- * name = CollectorsData.getCollectorNameByID(id) --- * iconFilename = CollectorsData.getCollectorIconByID(id) --- --- You can retrieve all collectors that produce a certain good (with any grade of --- efficiency) with the following getter: --- --- collectorNamesTable = CollectorsData.getCollectorNamesWithRecipeProductID(productID) --- --- There are methods to retrieve the lists of required goods, workplaces, and --- recipes, but it is advised to instead use the getter methods --- getCollectorRequiredGood, getCollectorNumberOfWorkplaces, and --- getCollectorRecipe with an index desired, which is good for loops. If --- you must get the tables, there are three "getAll" methods: --- --- * requiredGoodsTable = CollectorsData.getAllCollectorRequiredGoods(collectorName) --- * workplacesTable = CollectorsData.getAllCollectorWorkplaces(collectorName) --- * recipesTable = CollectorsData.getAllCollectorRecipes(collectorName) --- --- As a last resort, or if you need to transform the data structure, you can --- call the method getAllDataForCollector(collectorName) or --- getAllDataForCollectorByID(id). These return a whole record --- from the data table corresponding to the required display name or ID. --- --- The data table for collectors has the following structure: --- --- collectorsTable = { --- 	["collector1_ID"] = { --- 		["id"] = "collector1_ID", --- 		["displayName"] = "Plain Language Name", --- 		["description"] = "A long string with some HTML entities too.", --- 		["category"] = "Construction toolbar category", --- 		["sizeX"] = 9, size in tiles --- 		["sizeY"] = 9, size in tiles --- 		["requiredGoods"] = { --- 			[1] = { ["stackSize"] = 99, ["goodID"] = "good1_ID" }, --- 			[2] = { ["stackSize"] = 99, ["goodID"] = "good2_ID" }, --- 			[3] = { ... } or missing if fewer --- 		}, --- 		["constructionTime"] = 99, number of seconds --- 		["cityScore"] = 99, points? --- 		["movable"] = true or false, if it can be moved at any cost --- 		["initiallyEssential"] = true or false, if a new-game-starting blueprint --- 		["area"] = 99, tile radius --- 		["storage"] = 99, capacity --- 		["workplaces"] = { --- 			[1] = "Any", --- 			[2] = "Any", --- 			[3] = "Any", --- 			[4] = ... representing the number of workplaces, or missing if fewer --- 		}, --- 		["recipes"] = { --- 			[1] = { --- 				"goodID" = "good1_ID", --- 				"grade" = 9, number of stars, --- 				"gatheringTime" = 99, seconds, --- 			} --- 			[2] = { ... } --- 			[3] = ... or missing if fewer --- 		} --- 	}, --- 	["collector2_ID"] = { --- 		... --- 	}, --- 	["collector3_ID"] = { --- 		... --- 	}, --- 	... --- } --- --- @module CollectorsData local CollectorsData = {}
