You learned how and why you should extend the BasicGame class instead of implementing the Game interface directly.
You learned about the behavior of the constructors for the AppGameContainer class.
You learned that the start method of the AppGameContainer class calls the followingthree methods:
You learned about the behavior of the setup and getDelta methods in this module.
I will provide an explanation of the gameLoop method in the next module.
This section contains a variety of miscellaneous information.
Financial : Although the Connexions site makes it possible for you to download a PDF file for thismodule at no charge, and also makes it possible for you to purchase a pre-printed version of the PDF file, you should beaware that some of the HTML elements in this module may not translate well into PDF.
