使用MFC Visual Studio的C ++电子游戏

Question

I don't know if I had gotten it all wrong, so I'm asking for directions here.

Let's take for example, back in college, when you learned C++ and used Turbo C++ or GCC to compile, you get an idea of what a low level programming language is.

Now let's say I want to make a basic 2D video game, just as a personal project, nothing fancy, and I want to develop it using C++ just because. I'd code it using Visual Studio since it's a pretty good IDE.

Is it right to say "I'm going to use MFC" for this kind of project? (Consider the fact that I'd be using OpenGL).

Answer 1

MFC is a C++ framework that encapsulates the core elements of the Windows API. It's primarily intended for creating standard, windowed applications that the user interacts with on the desktop.

It comes with a built-in graphics framework: GDI. The one that was introduced with Windows, revolutionary for its time because it abstracted away hardware-specific details and allowed programmers to write general code that ran on any machine Windows ran on. But it was never particularly good for games; it was designed for Windows-style business applications. It was awesome for text (and is still arguably the best option that there is—have you looked at how Direct2D renders text lately?), and handled simple graphics, but consider that before alternative graphics-specialized frameworks like OpenGL were available, most game developers stuck with DOS, where they could/were forced to interact directly with the graphics hardware at a low level.

So if you want to use MFC and OpenGL together, you can , but I don't really see the point. The only real benefit you'd be gaining from MFC is a reduction of 100-some-odd lines of code that sets up the fundamental skeleton of any Windows application. For example, considering this sample OpenGL program , using MFC would essentially allow the WinMain and the MainWndProc functions to be buried deep in the bowels of the MFC framework code, rather than appearing directly in your code. But, like I said, big deal. The majority of your code is going to be OpenGL-specific, and MFC won't help there.

The only way it might make sense for the two to interact is if you wrote the launchpad/host for the game using MFC and GDI (ie, the part that displays windows and dialogs on screen), and then the game portion itself in OpenGL (launched once you clicked a "Start" button on the dialog interface).

And of course, even if you wanted to do this, MFC is not your only option. There are tons of C++ frameworks for writing Windows applications. Everyone has their favorite. Despite what some may tell you, there's nothing wrong with MFC if you already know it and/or are comfortable with the Windows API. But don't waste time learning it. Use WTL instead.

Answer 2

You would NOT use MFC simply because it is meant for general application development giving you features and classes that you will most likely never use!

A good start would be to look at SFML http://www.sfml-dev.org/ or (my personal favourite) SDL http://www.libsdl.org/ . These libraries were written to develop games or at least multimedia applications using them.

Writing a Game Editor in MFC can be a good idea though!
