o	Timer timer		= Timer that runs every 20 milliseconds to render image
o	boolean Start, gameEnd	= Set to either true or false to run the code when the game has started vs hasn’t started
o	int ticks, yVel		= Manages ticks by adding 2 and the yVelocity of the bird
o	ArrayList<Rectangle> walls		= ArrayList that holds walls
o	boolean fall		= After the game ends, the boolean will tell it whether to have a yVelocity of just freeze
o	boolean spaceDown		= When space is pressed it sets yVel = -10
•	Methods:
o	public GamePanel()		
o	public void actionPerformed()
o	public void paintComponent()		draw score, pipes, bird and background objects
