A while ago Charles Nicholson wrote an article about how they handled asserts in their engine. I kind of liked the title "Stupid C++ Tricks" and it triggered this article idea. Then since of course Noel Llopis managed to beat me to it, that after I've given him a hard time about his infrequent posts :) So without dwelling too much on why there are so many books and articles about traps, pitfalls, stupidity and secrets regarding C and C++ here you go; some more stupid tricks, don't try this at home.

This post is going to be a little bit different. I'm going to try at some humor, with just a lace of truth to it to be sad.

Determinism in the game itself can be used to easier reproduce bugs, gather performance data and even for gameplay itself. In modern games it does take a little bit of work if you have not had continuous tests during development to catch errors like when a game diverges. Recently I've had to do this as part of our graphics tests at work where we run the game in a special test mode and make sure that recent changes have not broken any rendering features.
