Key input doesn't work

[MedievalMagic13]

Hello everybody. I have a problem with keys in Irrlicht. When I want to close my program with the ESC key, it doesn't respond to it. Actually, every action I want to do doesn't work. I've tried it witch several keys and codes, but it doesn't seem to work. This is my code for shutting down the program:


...

IrrlichtDevice *device = NULL;
SEvent event;

scene::ICameraSceneNode* camera = 0;

class MyEventReceiver : public IEventReceiver
{
public:
virtual bool OnEvent(SEvent event)
{
if (camera)
return camera->OnEvent(event);

if (event.EventType == EET_KEY_INPUT_EVENT &&
event.KeyInput.Key == KEY_ESCAPE &&
event.KeyInput.PressedDown == false)
{
// user wants to quit.
device->closeDevice();
}

return false;
}

};

...

I put this code before all the other code (except for namespaces and headers).

Does somebody know what's wrong with it?

Thanks.

thats because you're sending all of your events to the camera, and automatically returning the result.

either put your key handlers above the Camera code, or when the camera returns check to see if it returned false- and if so, try to handle the event yourself.

Thanks for the answer Keless. I'll try it out as soon as possible.

It doesn't work. I can see the windows taskbar when I press ESC, but the program doesn't want to close, instead it's totally jammed.

This is my code at the moment (if I did it the right way):



SEvent event;

class MyEventReceiver : public IEventReceiver
{
public:
virtual bool OnEvent(SEvent event)
{
if (event.EventType == EET_KEY_INPUT_EVENT &&
event.KeyInput.Key == KEY_ESCAPE &&
event.KeyInput.PressedDown == false)
{
// user wants to quit.
device->closeDevice();
}


if (camera)
return camera->OnEvent(event);


return false;
}

};


Did I do something wrong (I hope so)? If so, could somebody please show me his/her code about how to close the programs?

You can remove the first global define of "SEvent event". It's being overlayed by the SEvent event in your OnEvent().

The other piece is that your main loop needs to check if the device is still there, if not.. end.

The tech demo does this.

Thanks for your reply Saigumi (and of course also thanks to Keless).
It works perfect now. I removed the global SEvent en included a check for the device in the main loop, like you said. Thanks a lot.
