I've got an idea for something, but I don't know how to do it haha
So imagine a racing game, where you can email your lap times and ghost car data to a friend from inside the game - or at least be able to download a file which you send to a mate who then uploads it from within the game. Then when they play the game they see their own ghost and also their mates one(s).
Firstly - ghost cars, I'm thinking of storing the data of the cars position every frame in an array or something? I've never used arrays.
Second one - Emailing / sending data from within the game, not sure how to go about this. Maybe email / downloading is the wrong way to go about it even. A buddy / user system might be better.
Anyone have any tips on how to get started coming up with a solution to this?
