Game Development

I've assumed your Qt/3D is in /opt/Qt-4.8.0/include/Qt3D in the .pro this must be changed to wherever your insall is.

Doing a sprite animation is simple, Create an array with the list of your pictures. You can have an timer which will advance this array. Go through the "Qt Flying Bus example":http://developer.qt.nokia.com/wiki/Flying_Bus_Game You can find the FrameSprite, which will give you the idea about how to achieve it.

Thank you so much! Very much Appreciated..

That's because, you can't just create a "hole" in the image. But, you can write your own function, which will change any necessary pixel at that image to transparent.

No, I'm talking about GL_ARB_debug_output.

The good news is that once you familiarize yourself with the programmable pipeline you'll never look back!

You still get to use glDrawArrays ;) What you lose is the matrix stack and the fixed rendering functionality (meaning you have to implement shaders yourself). What you win is a ton more control to what you're doing, which I personally like immensely. See here for example about the changes: http://www.jeffwofford.com/?p=698

I've somehow gotten it to work by creating an entirely new project with just a symbian target and copying all my stuff over (unchanged). Is there a known issue regarding projects with both the qt simulator target and the symbian device target?

[quote author="Reptile" date="1324699470"]Hey, I'm without my N8 for a week or so, but I've just finished writing openGL code for a game in the simulator, including using QGLWidget::renderText() for text rendering. But I read that it's not supported by OpenGL ES? Does that mean it won't show up on the phone or will cause other problems? Does anyone know if renderText() will/won't work?[/quote] FYI: don't use QGLWidget::renderText(). you'll get this message: [Qt Message] QGLWidget::renderText is not supported under OpenGL/ES

why do you trigger a repaint in the repaint? >> without QTimer::singleShot(0, this, SLOT(updateGL())) paintGL() Func is not repaint in this case @void Display::paintGL() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glClearColor(0.0, 0.0, 0.0, 1.0); glPolygonMode(GL_FRONT_AND_BACK, GL_LINE); static int Angle = 0; ++Angle; glPushMatrix(); glRotatef(Angle, 0.0f, 0.0f, 1.0f); glBegin(GL_QUADS); glVertex3f(-0.5, 0.0, -0.5); glVertex3f( 0.5, 0.0, -0.5); glVertex3f( 0.5, 0.0, 0.5); glVertex3f(-0.5, 0.0, 0.5); glEnd(); glPopMatrix(); }@ where exactly does it crash? >> it is not crash all the time and it's crash point is not same all the time and this crash is fixed QTimer::singleShot Func's msec value change (0 -> 10) By the way, a side not to your first post>> I'm sorry. and thank you for your Advice Gerolf :) and thank you all. dude!

I think the best way to do it will be, pause the game when it loses focus or when the application being sent to the background. And the application logic is in JavaScript.

I found the problem, I'm using a single buffer, not double buffer. I commented glutSwapBuffers() out and it works fine.

We found the problem, it come from an ATI dll.

I moved your question to the gaming subforum where the gaming developers reside most.

Here i found a working demo: QtSDK/Demos/4.7/qmediaplayer

Yeah, I did suspect that was the case, no problem there, it just seemed a bit awkward to me to be addressed that way ;) Cheers and good luck!

i got bullet physics working nicely with my opengl app, see the link in my sig for a demo on n9/meego harmattan.

ok thanks i will implement their ideas to see what I find not a calendar btw ^^ really thanks greetings
