Adding a Background Image
Next, you'll add a little more spice to your game by adding a background image. With the source code for this chapter (again, in the AnimatedSprites\Content\Images folder), you'll find an image named background.jpg. Add the image to the project the same way you added the other images (right-click the Content\Images folder, select Add â Existing Item..., and navigate to the background.jpg image included with the source code).
Your SpriteManager
class was built to handle
animated sprites and derived classes. Something as simple as a background image can
just be added to your Game1
class. You'll need to
add a Texture2D
variable for the image:
Texture2D backgroundTexture;
and load the Texture2D
image in the LoadContent
method:
backgroundTexture = Content.Load<Texture2D>(@"Images\background");
Next, you'll need to add the code to draw the image. Because you'll now have
multiple sprites being drawn within your Game1
class (the SpriteFont
counts as a sprite, so
you'll be drawing a score sprite as well as a background sprite), you need to make
sure that the score text is always on top of the background image. Typically, when
trying to ensure that one sprite is on top of another, you modify the SpriteBatch.Begin
call to include an appropriate
SpriteSortMode
. However, this is a case where you're only drawing two items, and you know that you'll always want to draw the score on top of the background. As such, you can forego the overheard involved in specifying a sort ...
