A case study in object-oriented development: code reuse for two computer games

A case study of the object-oriented development of two computer games using commercially available products was conducted. The games were constructed for use on Apple Macintosh computers using a C+ + like programming language and an accompanying object-oriented class library. Object-oriented techniques are compared with procedure oriented techniques, and benefits of object-oriented techniques for code reuse are introduced. The reuse of object-oriented code within a target domain of applications is discussed, with examples drawn from the reuse of specific functions between the two games. Other reuse topics encountered in the development effort which are discussed: reuse of operating system routines, reuse of code provided by an object-oriented class library, and reuse of code to provide functions needed for a graphical user interface.
