I agree with Alan's suggestions.For a .ini file, only put key-value pairs in there that control things like the settings of the game, such as the screen resolution, or visual effects settings. That way, if the game, with the visual effects enabled, won't run on the player's machine, they can go into the .ini file and disable those effects to get the game to play.
For more important settings, such as AI or gameplay stuff, use a method like Alan suggests. This would keep the ordinary users from cheating in your game. The more advanced users will figure out your encryption methods, eventually, and that's ok. You can't expect to make the game 100% cheat-proof.

If you just don't want the average player to be able to easily edit your game, you could do something like add a constant to every byte in the file, or xor it against a constant. if you use either encryption method (not very secure, but effective against 99% of the people atleast) , you can undo "addition encryption" by subtraction and you can undo "xor encryption" by doing the xor again. in C++ the bitwise xor operator is the carrot (carret?) ie: ^ hope that helps (:On 2/8/07, Edilson Vasconcelos de Melo Junior <dirso@xxxxxxxxxxxxxxxxxx> wrote:Hi, I'm working on a racing game and the racing tracks, cars and car updates (like engine, suspensions, NOS) could easily be read from a .ini file. Myproblems is if I use .ini files, the player could edit those files and thencheat on my game. What could I use for that? Thanks a lot, Dirso -- No virus found in this outgoing message.
