Welcome!

Hey all,

i'm from the QML Subforum but i thought why don't i try game development, just for fun and to gather some experiences. What i would like to know is:

Should i start with OpenGL or DirectX(DX3D)?
Are there any good tutorials or introductions to game programming and OpenGL/Dx you guys could and would recommend?

Every comment is welcome.

Hello, Qt guys
bq. Now that everyone agrees that a game forum is good, people should start posting information such as experiences, tips, dos and don’ts, resources, links, tutorials, etc. to make this a vibrant forum.bq.
This is a good point of view, tutorials is the best way to learn.

Well i would say the best way to learn something is to try and do it yourself.

Every comment is welcome.[/quote]I'd imagine that it depends on what kind of game you want to produce, and what experience you have.

For simple mobile games, I'd go with QML (e.g. http://qt-project.org/doc/qt-5/qml-advtutorial.html ) -- one code base that can be compiled for both OpenGL AND DirectX!

I would really like to go into 3D Desktop games, until now i have no experience with that.

Qt 3D is in the works, but it's not ready yet. Optimistically, there might be a tech preview in Qt 5.3.

Alright, thank you JKSH.

Thanks ![/quote]

I wouldn't bet my future on that, but I've may have missed the irony... ;-)

Qt Game development!

All people here have to say is that it's great with this new forum...
I thought I'd bring it one step longer then "hello group!".

Qt for games on mobile devices? Desktops? Consoles?

Qt is a joy to work with and thanks to QML and QML/3d and I guess it could be a good framework for game development.
I still think you would need to use OpenGL support if you want hardware acceleration that handles graphics/3d intensive programs.

If Qt is thinking about over-encapsulating this into some quasi game framework using QtQuick when "QGLWidget":http://doc.qt.io/qt-5/qglwidget.html would give you an excellent OpenGL context to work in, I don't know.

If no draw calls from other threads than the main thread is possible, this will not work well...

There is already a Game Framework based on Qt 4.8 called "V-Play":http://v-play.net/

I've tried it out as a demo, but it didn't impress me all that much.

So I really hope that Qt's focus on Game Develop will bear fruits!

Signals and slots for gamedev == cool, so the best of luck!

I would definitely learn as much as possible about OpenGL (for the Desktop / Console market) and OpenGL ES for mobile.

But Qt has an excellent solution which makes working with OpenGL a lot simpler:
The QGLWidget class is a widget for rendering OpenGL graphics.

Read all about it: "QGLWidget docs":http://doc.qt.io/qt-5/qglwidget.html#details.

You could also take a look at a Game Engine / Framework that uses Qt 4.8 here: "V-Play":http://v-play.net/.
