Hi,

I'm trying to tidy up some code on a game I'm working on by seperating it into classes. My main class is called "main" and my second class is called "JetFighter". How can I call and initialize the Jetfighter class in the main class?

Well, generally, we'd need more details; however, let me just say that the JetFighter class *should* know most (if not all) that it needs to know to intialize itself. Thus the advantage of "Object-Oriented" design...

This is usually done via the constructor. The Main class may need to pass some parameters to the JetFighter (to fill in the blanks - so to speak) but other than that, it will know how to handle itself.

I hope this helps,

I would read up on classes a little bit more, its way to advanced of a topic to just explain it in the forums.

Using classes is not really a tidying up exercise so to speak, you may be wanting to just seperate functions into different files which is alot easier. Although learning to use classes is no bad thing, if you do that then people here will be able to help you with more specific questions if needed.

OO programming is ideal for game writing using classes but alongside classes you can use the 'list' commands in c++. Using linked lists helps tidy up your code because everything is controlled from within the class and the data is stored neatly in a linked list. Have a study of these pages for more information on lists.

GDK may be a bit cumbersome assigning objects to a constant number instead of a variable but used with this:


... can add a little more OO to DGDK.

Can you use a static list in a class in c++ and then auto add the instance in the constructor? I forget, but you can do this i c# and the class automanages all instances of itself, really cool stuff

List were causing me some problems for a short while because I'd not used them for a while but here's something I've just figured out. Using classes and a linked list:
