As you can see all we have done is to add values for frames and fps in the GraphicsResource constructor for those images that will now be animations.

The final step is to modify the game elements that should now be animated to extend the AnimatedGameObject class instead of GameObject, and to create some explosions when we destroy a plane.

Both the Player and Enemy classes will be animated, and both will create an explosion when they are destroyed. The code changes are the same for both classes, so I will show only the new Enemy class. You can download the source code at the end of the article to see the changes made to the Player class.
