Hello,

I search to implement Irrklang in Irrlicht.
I have find the irrKlang scene node for Irrlicht 1.5 and use them with Irrlicht 1.7.2. At first look the code is correct.
But I have a problem : when I play a sound is the render loop it crash (in EventReceiver).

And I don't see a source listener and emitter ?
I missed something ?

Thanks,
RVM

Hello,

I use this function to play a song :


void CPlayer::Play_Sound(char Sound_Name)
{
    switch(Sound_Name)
    {
    case 'C':
        //Crash here
        Player_Sound_Node->setSoundFileName("./media/son/crier.wav");
        break;
    case 'T':
        Player_Sound_Node->setSoundFileName("./media/son/getout.ogg");
        break;
    default:
        break;
    }
}

And in my render loop :

        if(EventReceiver.IsKeyDown(irr::KEY_KEY_Z))
        {
            Player->Set_Position(Player->Get_Position()+irr::core::vector3df(0,1,0));
            Player->Play_Sound('T');
        }

Here is my complete class :

First I was thinking it was a incorrect file but no...

By shortly taking a look at this, it looks ok for me. Where exactly does it crash in your event receiver, and why? Are you for example sure that the Player pointer is ok?

Normally the pointer is ok.
Here is my render loop :


    while(Irr_Device->run())
    {
        const irr::u32 now = Irr_Device->getTimer()->getTime();
        const irr::f32 frameDeltaTime = (irr::f32)(now - then) / 1000.f;
        then = now;

        VideoDriver->beginScene(true, true, irr::video::SColor(255,100,101,140));
        SceneManager->drawAll();
        GUIEnv->drawAll();

        irr::core::stringw Title = "RhombiWord Driver : ";
        Title += VideoDriver->getName();
        Title += " FPS : ";
        Title += VideoDriver->getFPS();
        Irr_Device->setWindowCaption(Title.c_str());

        cam->setTarget(node->getPosition());

        irr::core::vector3df nodePosition = irr::core::vector3df(0,0,0);

        if(EventReceiver.IsKeyDown(irr::KEY_KEY_Z))
        {
            Player->Set_Position(Player->Get_Position()+irr::core::vector3df(0,1,0));
            Player->Play_Sound('T');
            //node->setPosition(node->getPosition()+irr::core::vector3df(0,1,0));
        }
        if(EventReceiver.IsKeyDown(irr::KEY_KEY_S))
        {
            Player->Set_Position(Player->Get_Position()+irr::core::vector3df(0,-1,0));
            //node->setPosition(node->getPosition()+irr::core::vector3df(0,-1,0));
        }

        if(EventReceiver.IsKeyDown(irr::KEY_KEY_Q))
        {

        }
        if(EventReceiver.IsKeyDown(irr::KEY_KEY_D))
        {

        }
        VideoDriver->endScene();
    }

And it crash at line : Player->Play_Sound('T');

If I comment the line, I can move my Player.
I am not a pro in debugging, but when I put a break point at this line, I have a SIGSEGV error...
I will a learn a bit more about debugging.

Just a question, Irrklang use a thread for playing a song ?

hello, I have the same problem.

CIrrKlangSceneNode::CIrrKlangSceneNode* soundNode =
new CIrrKlangSceneNode::CIrrKlangSceneNode(soundEngine, smgr->getRootSceneNode(), smgr, 666);

//soundNode->setSoundFilename
soundNode->setSoundFileName("media/fallout.wav");
soundNode->setMinMaxSoundDistance(30.0f); // influences the distance where the sound can be heard
soundNode->setRandomMode(1000, 5000); // plays sound multiple times with random interval

// other modes would be:
// soundNode->setLoopingStreamMode()
// or
// soundNode->setPlayOnceMode();

soundNode->drop();

When the code:
soundNode->setSoundFileName("media/fallout.wav");

is commented out. all works fine.
//soundNode->setSoundFileName("media/fallout.wav");
So what is the bug?

Cheers
