hi, thanks so much for wanting to help

basically i am making this virtual reality electronic learning application, where the user will be able to move around and then click on a planet, once they click a website opens up with the information on that planet .

oh and also when the webpage opens up, they can then also navigate to more information such as watch a video, take a quiz or see information about the planets moons.

It sort of helps if you have a use case diagram as well. Your class diagram is based off your use case diagram.

To me it looks okay for a first draft, I've personally never used aggregation in a class diagram before so wouldn't know how to help there. But there are a lot of improvements to be made.

Some things to point out

•

Player interacts with the map so there should be a relationship between Map and Player

•

If this is gonna be for a final year project you really should be looking at the Boundary, Control, Entity model. A lot of these like SoundManager and VideoManager are classed as a controller which interacts with an entity. This means a video is a class, and so would sound and texture, each containing attributes of their own. The webpage itself would be a class too.

•

What is the application control, is it a form of GUI?

•

You are missing a quiz class as well. Why is quiz an attribute in your planet object?

•

You might want to rethink your attributes. Make sure you uniquely identify your entities with ID values, e.g. player, planets and map (if there are multiple maps)

•

Is there a database which holds the information? if so, you need to include this in your class diagram.

•

Operations and attributes should ideally begin with a lowercase letter. Classes begin with an uppercase letter.

If you want, but remember if you create new classes in your class diagrams, you'll have to add them to your use case diagram too.

Bootstrap allows you to use any online template that uses Boostrap if you have the files on your website. Which part are you stuck on?

well , my domain model and use case diagram only share some of the same stuff.......

also for the bootstrap thing , i am using the CDN instead, which basically uses an active internet connection to get all the bootstrap classes. All i need is a pre-made template i suppose?

If you are already importing the bootstrap classes in your html file, all you need to do is copy and paste some HTML code (like a navigation bar or menu) into your body of your website and the styles should be displayed.

Click on the template you want and then there should be a blue menu at the top with options like "HTML, "CSS". Click on them and just copy + paste the code into your HTML page. CSS should go in a CSS file though, then you just reference your CSS file in the HTML page using <link rel="stylesheet" type="text/css" href="theme.css">
