As far as I know there isn't, unless someone else corrects me. But I'm guessing you're asking that because the user can change the contents during the game. I think the way you should look at this, is that the design time info is like a starting point. where you start from when starting off with the game. I think you should use the local storage plugin to save the dictionary/arrays, and on start of layout check: if the item exists in local storage, load it from local storage ELSE load it using ajax from the project file.
but maybe I don't understand the use case well, so hope it helps?
I think you got it right. I just wanted to save back values to the file after loading it. So say I loaded values:
Key = potions, value = 0.
Then player acquired 10 potions. So I save that back into the same file:
key = potions, value = 10.
So next time the player launches the game, the amount of potions they'd have is 10.
I guess what you suggested should work -- will the system "Save" and "Load" actions work here too? Because I care more about saving the data than "where" to save it or must I use the local storage?
