I have the worst feeling that this is going to be a nightmare...
One day and MANY, MANY changes later I realize: I'm a moron. I finally got around to updating my game object system to account for the changes I made, just to realize: there really isn't anyway for me to have a 'game object' that is loaded from a file without it containing said state data (yes, I could have GameObjectData and a separate GameObject class, but I'm really not a fan of that design.)
So, I think to myself: I can just use cloning on my AnimatedSprite class when it's importing! Wait a minute, what's this? 'AnimatedSprite : ICloneable' Yup, I was already using cloning as it was the solution I implemented to allow me to finish the 2nd prototype for SAGE. I feel so smart right now, you don't even know.
As I use source control I can easily revert my changes. The problem is, I don't remember what all of those are other than 'I had some good ones...somewhere.' Time to trudge through my source control.
Forever and a day later...I'm finally done reverting and updating. I ended up trudging through the diff for each file to decide whether or not I wanted to revert (very few to no changes) or if I wanted to skip/manually revert. In the end it was totally worth it as the asset system is way better and I have a basic GameObject system in place.
Bed time for now, but back to work on SAGE tomorrow!
