I was recently told that my code is missing the Rule Of Three concept, and that my timer isn't const-correct.
I know of these terms; but google and searching the forums didn't help much.
I think what would help, however, would be an example of each concept (Rule of Three, Const-correctness) related to Game Programming. I know what the Rule Of Three is for (creating copy ctor, assignment ctor, and dtor), but I don't completely understand why. Also, I know that RAII/smart pointers take care of all that altogether, but I'd like to understand the Rule of Three.
As far as const-correctness, I think that it means that when you pass a variable by reference to a function, you should pass it as a const so that you're assuring it doesn't get changed. does this mean that in my game loop, the Update(int &deltaTicks) function should be Update( const int &deltaTicks )?
