Introduction
Many game programming books tend to focus on their own custom libraries or building a game library that contains many basic game functions that can be reused between applications. Now that we have covered many of BREW's features suitable for game development, it is time that you learned how to create your own libraries. In this chapter we focus on how to create an extension class, essentially the BREW equivalent of a Windows DLL. Although not a full-fledged game library, we will walk through the process of creating an extension class for use with the simple Hello World applet. After this exercise, you will be ready to create your own custom classes with whatever functionality you wish to abstract.
