Legacy GM Multiplayer Security

[Marcos Ferreira]

Good Morning!


I would like to know how to protect my multiplayer game. I developed a lot of it, I already have a playable demo in UDP. However, as it is a little discussed here in the forums, I would like to know if there are any good links on the subject. Not only to protect the communication of the game to difficult the hacks, but also to try to prevent decompilation.

Sorry my english!

Thanks!

Interesting topic. I don't think you can do a lot about de-compilation and reverse engineering. You are working on some standardized platform, on which you don't get to change a lot of low lever executable stuff.
Also if you want to to have protection against hacks than you could try to: encrypt the connection (although this is not that necessary for a game, but if you don't hackers could theoretically send false packages that say their coming from a certain player and making that player move).

For players hacking themselves, you could do speed movement checks and have some code you are doing inside your clients also done on the server and compare if it add up correctly.
