For example, imagine a game where you collect objects (like coins, gems, keys, etc.), and the ones you pick disappear like they do in any other game where you collect coins. So, you are in level "A", you collected some coins, then you go to level "B", and when you decide to go back to level "A" the coins you collected in that level never appear again because you already have them, but the ones you didn´t collect are still there. How can I do this?
I already know how to use the "edit object" actuator with "end object", as well as "set scene" to change levels, but when I do that, the already collected objects always appear again when I go to the second level and go back to the first, and that´s not what I want.
Python is preferred, but I dont mind using the logic bricks.
