This code is clearly not perfect, but the from what I've seen, this is something I could work with.
- Function names are easy to read and understand. - Indirections are kept to a manageable level.
Old players maybe remember that the crysis multiplayer was the most cheated game in its era. It was totally unplayable due to all the cheating and that killed the game.
One way to make cheats. You could load up the SDK in visual studio. Find the code that's removing -1 ammo when shooting and edit it to not do that (most of the physics and game logic was editable that way). Compile the DLL. Replace the original DLL in the game directory.
The most famous example I can think of was UOExtreme revealing hidden players, because if a player was hiding their presence was still sent to the clients of every other player in the area just with a "hidden" flag set. There were a bunch of other similar exploits associated with that particular third-party tool, but that's the only one I remember.
(so while writing this I did some googling and found the patch notes where they fixed it: https://uo.com/wiki/ultima-online-wiki/technical/previous-pu...)
Good game though, I think Crysis 1 multiplayer is to this day one of the most fun multiplayer games I have played. After Crysis 1 they really CoD'fied the game, which is a shame. That and BF2142, A-plus games.
Looking forward to Crysis Remastered, hope they don't screw it up.
