GO Language. Each component may be drawn as a simple box or more ornately as a file-folder-like icon or a box with two tabs on the left-hand side as if it were to plug into something. Draw simple lined arrows between the components to indicate dependencies. The component diagram is a great tool for developing a road map for maintaining a body of code and for working with a team of developers in general.

Also, if your body of code is becoming tangled and your build times are growing out of control, mapping the dependencies between the classes across your project may guide you to perform some surgical refactoring to bring your builds back under control. In fact, the class, component, and deployment diagrams share the following UML structures: stereotypes, generalizations, and associations.

The deployment diagram acts as the most natural extension of the component diagram, the physical arrangement of your software system and subsystems with a pictorial description of the delivery platform and where the major components live on the delivery platform. For many games, especially console games, the deployment diagram would be a simple diagram with just a single machine being the platform. However, in the case of very fast hardware video and hardware audio, it may still be useful to depict what subsystems of the hardware the various bits of your game engine are running on.

Deployment diagrams are an excellent opportunity to use all of the Visio stencils that are lying about. You can use a cloud to represent the Internet, different server icons, modems, satellite dishes, whatever you want; the deployment diagram is the diagram that expresses the software in its most physical terms. A sample deployment diagram based on SFC3 and D3 with clients, servers, and web site. As shown in Table 2, there are five diagrams to assist in describing the dynamic behavior of software.

It is an inherently flawed process to render onto a 2D plane the time-dependent dynamic behavior of software. There is no guarantee that the software should not rightly take up more than two dimensions in representation and no guarantee that it will lay its time component out nicely to be read top to bottom or left to right. That may be one reason the UML has defined more five diagram types for the dynamic behavior of software compared to the four diagram types of static behavior.

You are already familiar with the handiest of the dynamic behavior diagrams, the use case, but what are the rest of the dynamic diagrams about? Activity diagrams are useful for documenting the behavior of objects that have complex state-changing behavior. A programmer I knew from my earliest game programming job used to exhort rather menacingly about the lack of appreciation we younger programmers had for the state machine.

I have to admit that while I had a general idea what the guy was talking about at the time, I did not understand exactly why state machines are a panacea to programming. I believe what the older programmer was trying to say was that the failure of younger programmers to visualize and understand the state machines we were already creating caused a lot of bugs. Thus, the utility of the state diagram to visualize and model objects with complex state behavior.

The first bit of notation you will immediately pick up on is that the boxes in an activity diagram are round edged; these are the states that your object transitions between. Each of the transitions in your object should be documented with the guard condition , which is a boolean condition that when met allows the object to pass to the new state.

There are also two predefined states for all objects in the UML notation: the start state and the end state, represented by solid filled circles, with start usually placed at the top of the diagram and end at the bottom.

It is common for an object to transition among a set of related activities states while at the same time open to being interrupted and transitioning to another state that is connected to all of these related states. Sequence diagrams are designed to address the need to model the dynamic behavior between objects. Again, the state chart tracks the changing of state internally in an object, while the sequence diagram tracks the communication occurring between a number of objects.

The sequence diagram is useful for designing how your components and packages will interact at the specification stage and assists you in designing the message traffic in your objects in the implementation design stage. A sequence diagram documents a single scenario or course of events. In fact, a sequence diagram maps well to a use case diagram.

You should certainly spend more energy on collecting your requirements into use cases rather than rigorously ensuring that you have a documented sequence diagram for each of your use cases. The main benefit of sequence diagrams in game development is in multiplayer code technical design. Multiplayer code tends to need a lot of asynchronous callbacks, multithreading, blocking calls, or combinations of all of these.

You also have peer-to-peer or client-server communication. There is usually a lot of complicated messaging going on. Zachary Drummond and I independently developed sequence diagrams on our own while working on a client-server game in Later we found out there is a standardized language for expressing this messaging behavior!

There aren't any multiplicities. An interface without any operations doesn't make sense. An operation to make a move is missing. I think you're totally lost. What kind of chess is that? Ever since it has 8x8 fields which can be occupied with figures. There's nothing which can express that. Well i have never made a program completely from scratch without instructions, therefore i needed someone who's good at that to provide a UML diagram for a relatively simple 2 player chess game cause i know my UML diagram has many problems.

But maybe thats asking for too much.. Add a comment. Active Oldest Votes. First some formalities: use the arrows for the relationships only to indicate navigability. If the link is bidirectional, either use 2 arrows or none. For example, here we could understand that View knows ChessBoard , but it is not clear if ChessBoard knows about Views : how can the ChessBoard then inform Views that the state of the board has changed after a move was done?

For example, in View , you have a model property of type ChessBoard. But you also have an association with ChessBoard. So is this all the same ChessBoard? Or do we have two ChessBoard s, one associated and one embedded? It would be clearer to remove the model from the properties, and indicate model as the name of the asscoiated object at the end of the association. The association starting from Controller that suddenly splits into two is not very practical, especially if you'll tell us about association ends and multiplicity.

Prefer to visually have two very distinct lines. Now to the core: Your model should not just be a ChessBoard. The model should be a Game that has a couple of elements. ChessBoard is only one of them: the current position of the Piece s. But what about the layers? Where are they?
