Class 3 Input Handling

in class

Extract sprite from pacman class and build new project

http://www.xnawiki.com/index.php?title=Basic_Sprite_Class

Sprite class

IntroPacManComponent.zip

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

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
