I have no idea where to start when creating a class diagram. I am just drawing it out on a piece if paper so I do not need any special software at the moment. How do you know what all your classes need to be and how do you know what methods and fields/attributes that they are going to have? One thing to keep in mind (I do not know if this will affect any answers). This game I am creating needs to implement the strategy pattern, and it also needs to use the model view controller. Thanks a bunch.

When I diagram, I only draw out major parts of the application. I don't go down to the level of classes and methods very often, and certainly never when I'm first starting to plan out a design and architecture.

Also, with something like the Strategy pattern, I never start out with the intent to implement that particular pattern. With me, the Strategy pattern is always something I recognize after seeing certain aspects of my design evolve after I have gone through several iterations of test/code/refactor.

The MVC pattern is something you can have in mind from the start since it is general enough to actually be useful in guiding your high-level module design and architecture.

Duplicate of this thread.

Please do not post the same question to multiple forums. I'm locking this topic, please continue the discussion in the other forum.
