This is a simple demonstration on how to encrypt data for your game. If you want to use this to encrypt data for your game then expand on it to make it a bit harder to crack .

Nice. Not exactly going to fool MI5, but if, say, i'm putting my game story bits into text files and don't want someone reading them outside the game, this would work.

Pretty cool, though I think you over-did your code a bit. It's easier to forget about the arrays and just do something like this:

Done and Done. When You compare each version together you will notice that it encrypts it differently. I can't figure out why. They should both change the ASCII by 10 but you can see it encodes it differently.

Seems that in the original, when you encrypt, you took away 10 rather than added it on, vice versa. My bad I guess

@Zotoaster
ah thats what it was couldn't figure out why it was different. I was a bit tired last night, quite easy to overlook the addition symbol for a minus.

@WindowsKiller
Is that what it is called. I basically followed the tutorial on GameDev. I was surprised how similar the commands are between DarkBasic and VisualBasic.
