[SOLVED] QT Irrlicht Integration

[ritti]

Hi,
as the title says I'm trying to integrate Irrlicht in QT.
I followed this tutorial: viewtopic.php?f=5&t=44658
It works great, but now I have a problem with all the stuff thats done during runtime (sending units around, collision detection...)
I started with the Irrlichts tutorial 07.Collision and built on it so that i can send units around and test for collision detection.
All this is done in a while loop in the main.cpp:

cpp Code: Select all

while(mainWindow.getIrrlichtWidget()->getIrrlichtDevice()->run())
    if (mainWindow.getIrrlichtWidget()->getIrrlichtDevice()->isWindowActive())
    {... //code to send units around and watch for collisions

But i have to

cpp Code: Select all

return app.exec();

otherwise the window wont be created.
Well if i return inside the loop the units are shown but i cant move anything because the while loop is over.
And if i return after the loop the Game wont never end the loop and the window wont be created.
Where do i have to place the loop or the app.exec?
I hope somebody can help me
Thx in advance

You should put the run loop in the paintEvent handler of the irr widget, e.g.

cpp Code: Select all

void QIrrlichtWidget::paintEvent(QPaintEvent *event)
{
    init(); // create device if not done
   
 
    if (device && device->run())
    {
        if (isVisible() && isEnabled())
        {
            driver->beginScene(true, true, video::SColor(255, 0, 0, 0));
            smgr->drawAll();
            driver->endScene();
        }
        else
        {
            device->yield();
        }
    }
   
    emit repainted();
}
