Anatomy of an XNA Game

Four important methods: Initialize, LoadContent, Update, Draw

Initialize

Used to set up objects and initialize variables once, before the game starts

Cannot use content yet, because it hasn’t been loaded.

LoadContent

Used to get content (images and sounds) into the game

Called only once, after Initialize

Update

This is where all of your game logic goes

Collision detection, updating subsystems, updating object properties

Runs at a target rate of 60 times per second.

Draw

Draws content on the screen using a Sprite Batch

Called as often as possible

Sprite Batches

A group of textures (images) that are drawn together before being sent to the graphics device for final rendering

All Zune games use sprite batches, whereas Xbox 360 and PC games can use other means.
