Because I want to add more advanced features and a more modular design I am working on redesigning this entire program. I'm wondering which of the two would be better? Ofcourse the traditional way would make a Entity header file then have the paddles be inherited from the class. But a more data oriented has caught my intrigue and thinking of using this approach. What do you think?

There is no clipping issue if the right paddle goes to high. But if the right paddle goes too low sometimes it skips pass the parameters

Its been a long journey reading books about State Machine implementation. The redesign branch will be for (surprise) redesigning this project. I have created a simple StateManager header file and State header file in the engine folder. My intentions for each member function were commented to make it clear how I intend to use them. Basically the game will have an intro, main menu, and game state. If you guys have any idea or changes for StateManager and State classes please feel free to post them here. In case you are not familiar with this design, I suggest you do a little research on it. ;)
In the meantime the definitions of these classes will be here soon
