-= Bullet Game
-Bullet Game is our near-end stage pygame 2d game framework example. We've already done at least 6 or 7 other games using pygame. So this will document the patterns we have learned.
-We began by "just writing" a game, then the second part was refactoring the game. I wanted to make refactoring it's own project. What are the goals of this refactoring?
-* Refactoring
-** Encapsulation
-** Light Commentary (code commentary) ex. IN and OUT for functions.
-The primary goal is encapsulation. So, we're going to break up the old main into several new classes.
-== Screen and Window
-The first thing we always do is have a Screen class and a Window class. The Screen class defines things like WIDTH and HEIGHT, and the Window class holds the pygame screen and other pygame initialization.
-Initially, this code would appear at the start of a main.py. Later we moved it into class Game's __init__. However, to keep things clean we made it into it's own class.
-=== class Screen:
-<Code:Python>
-</Code>
-=== class Window:
-| def __init__ | This calls pygame.init(). See [[main]] |
-| setLogo | this sets the little icon in the corner of the screen. It's the icon for the desktop, usually. Normally we don't care about this. |
-| setCaption | This will set the title of the window. Usually the name of the program or game. |
-| setFont | This will probably be moved to it's own Font class later. That way we can have multiple fonts if we want and it keeps the code a bit cleaner. |
