軟件工程方法Prefactoring
Prefactoring, in essence, is the art of applying the insights gleaned from previous experience (whether yours or someone else s) when developing software to new projects. Doing so will likely save you from making costly design changes midstream--and maybe even save your job!
The project Adventure is a simple text-based adventure game. The game, as given, involves the hero trying to find his way from a deep dark forest to home and his true love. There s very little else the player can do apart from moving from place to place. It s not really very interesting.
This project can be of use beyond the given, rather boring forest adventure though. You can use it as a basis for developing your own adventure game with different, more interesting commands, areas, items, people and so on.
The package ope.adventure contains classes to describe the game world.
