Hi,
I have one question, I have a little game, and it’s composed of one world (it still a beta), I want to know, how can I manage, to unblock a new mode on the main menu once I have passed the Single Player World.
Hope you could help me, lot of thanks.
Greetings
Use PlayerPrefs to store and retrieve data between sessions and optionally also between scenes.
There are essentially a lot of ways to achieve what you are after. Personally I would create a empty object and attach a script that handles the achievements etc. It is also possible for this game object to stay alive across scenes using code.
