In game pausing with cegui menus

[esr]

I've been tinkering around with a project in irrlicht and can't figure out for the life of me how to get an in game pause to work.

Code: Select all

bool pause = false;
...
while (device->run()) {
        device->getVideoDriver()->beginScene(true, true, video::SColor(255, 20, 20, 40));
        if (device->isWindowActive() && !paused) {
            DeltaTime = irrTimer->getTime() - TimeStamp;
            TimeStamp = irrTimer->getTime();
            UpdatePhysics(DeltaTime);
            device->getSceneManager()->drawAll();
        } else if (paused) {
            printf("Paused!");
        }

        CEGUI::System::getSingleton().renderGUI();
        device->getVideoDriver()->endScene();

    }

as it is, this code will pause the game but won't allow it to restart, and loses the scene (I'd like to overlay a transperancy)


However, on changing a couple lines to this:

Code: Select all

while (device->run()) {video::SColor(255, 20, 20, 40));
        if (device->isWindowActive() && !paused) {
            DeltaTime = irrTimer->getTime() - TimeStamp;
            TimeStamp = irrTimer->getTime();
            UpdatePhysics(DeltaTime);
            device->getVideoDriver()->beginScene(true, true, 
            device->getSceneManager()->drawAll();
            CEGUI::System::getSingleton().renderGUI();
            device->getVideoDriver()->endScene();
        } else if (paused) {
            printf("Paused!");
        }


    }

the game pauses, retains the screen image, but still won't restart. What am I missing?

Just keep the code in the while()-loop as you would do normally. If the game is paused stop the timer:

Also increments the virtual timer by calling ITimer::tick();. You can prevent this by calling ITimer::stop(); before and ITimer::start() after calling IrrlichtDevice::run().

This way everything stays in its current state since the timer doesn't tick anymore.
