What I'm asking is although I can do just about anything, is it worth learning how to use classes for PHP and using them in place of 'normal' (can't think of the word) code? From what...

This is in C++. So, I'm starting from scratch writing a game engine for fun and learning from the ground up. One of the ideas I want to implement is to have game object state (a struct) be double-buffered. For instance, I can have subsystems updating the new game object data while a render thread is rendering from the old data by guar...
