My first try didn't work. I'm going to try again. I'm intrigued with the idea that the nouns, verbs, and adjectives can indicate possible classes, instances, methods, and attributes. While I'm familiar with the objects in this TAG example, I'd like to have a way to approach something that I'm not as familiar with. I like the idea of this technique. It seems like it should work with just about anything that can be modelled as an object. I have a tendancy to think about things as actual objects (but probably not OOP objects -- more like real objects, like a vase). I also like techniques. I know this much: Explorer: has strength & wealth, can carry weapons & food, can wear armor, can pick-up treasure, can fight monsters, can wound monsters, can defeat monsters, can move from room to room. Monster: can be anywhere, has Ferocity Factor / Danger Level, can fight Explorer, can wound Explorer, can defeat Explorer. Treasure: can be picked-up, can be in any room in Castle (except entrance and exit). Castle: contains interconnected rooms, has three levels. Rooms: room has door(s), door(s) connect to other rooms, room has description, can contain treasure, can contain monster. The trick is to take all that stuff, and figure out what the classes are, the instances, the methods, and the attributes. So it seems I need to write something descriptive about exploring the above. Subject, verb, adjective object. I must start somewhere! 8^D The above is much smaller than my previous "pseudocode" attempt. > > I'd go for a more free-form paragraph or two(at most) something > like: > ------------------ > I want to build a text adventure game based around > an explorer moving around a castle with multiple rooms,.
