Sprite class

Project that refactors the pacman class into two classes

Sprite.cs DrawableSprite.cs

Then the pacman class can inherit from one of these two classes.

PacMan.cs

Due to the desire to limit the number of spritebatches, I've created two classes. The sprite class cannot draw itself without being associated with and external spritebatch. The DrawableSprite has it's own spritebatch which makes it easier to use but less efficient.

Classes and Generics

Shooting with pacman

List<Type> Safer than Arraylist and easier to manage than Array

Homework

• Sprite Class

Build a class that is reusable that can draw a single texture on the screen. Be sure to encapsulate all the properties and method that you need to draw the sprite.

Moving Game

• Create an XNA project that uses the Keyboard for input.
• Has at least 3 different moving sprite with a common code base.
• the sprites should inherit from the same class. Game components are a plus. don't worry about collision yet

• Read Chapter 3 in XNA 3.0
