SaveManager

If you need to save some game data, you can use SaveManager.

All that you need is create an object with save() and load() function and add it to windowManager:

local object = {}

function object:save(saveData)
    -- save data
end

function object:load(saveData)
    -- load data
end

fv.core.theSaveManager:addObject(object, 'myObject')

However, the better programming practice is to create a special class for this (see Classes for details):

MyClass = Class("MyClass")

function MyClass:save(saveData)
    -- save data
end

function MyClass:load(saveData)
    -- load data
end

local instance = MyClass()
fv.core.theSaveManager:addObject(instance, 'myModData')

Second argument of addObject() function is optional (but highly recommended) name of object.

Save/load

When game is saving SaveManager calls save() function. The only argument is empty lua-table "saveData". Feel free to fill any fields of this table by strings, numbers, bool values or subtables.

function MyClass:save(saveData)
   saveData.data = self.data
   saveData.uid = uidToStr(self.building.uid)
   saveData.num = 14
end

Warning! Do not place objects in this table. You can save UID instead.

Loading process is straightforward:

function MyClass:load(saveData)
   self.data = saveData.data
   self.building.uid = uidFromStr(saveData.uid)
   print(saveData.num)
end
