Ok so questions I have gotten quite a few times from those starting fresh with XNA Studio Express relate to what are the built in Methods in my code for when I start my project. This is a great question as XNA studio automatically plugs in some code for you when you create a new game project. These are there to take out some of the initial guess work and are the main building blocks any graphics oriented game application are going to need. To answer I always like to stick as close to the help materials as possible. In this case the XNA Studio Express help documentation handles this more than adequately. Here is the section explaining the built in code blocks:

 

Some of the hard work has already been done for you. If you build and run your game now, the GraphicsDeviceManager will handle setting up your screen size and rendering a blank screen. Your game will run and update all by itself. It's up to you to insert your own code to make the game more interesting.

Much of the code to start and run your game has already been written for you, and all have places for you to insert your code:

• The Initialize method is where you can initialize any assets that do not require a GraphicsDevice to be initialized.
• The LoadGraphicsContent method is where you load any graphical assets such as models and textures.
• The UnloadGraphicsContent method is where any graphical assets can be released. Normally, no extra code is required here, as assets will be released automatically when they are no longer needed.
• The Update loop is the best place to update your game logic: move objects around, take player input, decide the outcome of collisions between objects, and so on.
• The Draw loop is the best place to render all of your objects and backgrounds on the screen.

 

As this is a technology that has great interest for me I will continue to post answers to questions I commonly get in my blog here.
