Is there a way to save a variable's value between a game save and reload ?

[groovyclam]

I have a variable which holds how many times a deck can be reshuffled and reused before the game ends. During play it reduces towards zero as the deck is reshuffled.

Is there a way to save the current value of that variable if the user saves their TTS game state and then retrieve it when they reload the saved game at a later date ?

Found out how to do it:

The variable I want to save and reload is called deck_refills so make the follow code changes:

1. Give an argument to your onLoad function definition of saved_data:

function onLoad(saved_data)

2. Make an onSave function:

function onSave()

    local data_to_save = {saved_count = deck_refills}
    saved_data = JSON.encode(data_to_save)
    return saved_data

end

3. In your main code add the following (note in my game deck_refills depends on the number of players if it isn't loaded from a saved game ):

-- load any saved data from a previous game save
	
local loaded_data = JSON.decode(saved_data)

-- check if the load, loaded anthing

if ( loaded_data == nil ) then

        -- it didn't, so set deck_refills to -1 temporarily
	deck_refills = -1

else

        -- it did load data, so set deck_refills to the loaded data
	deck_refills = loaded_data.saved_count

end
	
print('Deck Refills loaded as:' )
print(deck_refills)

-- if I set deck_refills to -1 I have to set it based on the number of players
	
if ( deck_refills == -1 ) then
	
	if num_players == 3 then
		deck_refills = 1
	else
		if num_players < 3 then
			deck_refills = 0
		else
			deck_refills = 2
		end
	end
		
print('Deck Refills loaded as blank/-1 so set to:' )
print(deck_refills)

end
