problem with event receiver

Efrint · Post by **Efrint** » Sat Dec 10, 2005 6:07 pm

Hello,

I´ve got a problem with my event receiver. If i use it, the whole programm crashes....what did I wrong?

here is my code:

Code: Select all

class EventReceiver : public IEventReceiver
	{
	public:
		virtual bool OnEvent (SEvent event)
		{
			if (!event.KeyInput.PressedDown)
			{
				switch (event.KeyInput.Key)
				{
				case KEY_KEY_A:
					{
						Key_A = true;
					}
					return true;
				}
			}
			else
			{
				Key_A = false;
				return false;
			}
			return false;
		}
		
	};

I get no compiler error, but it just doesn´t work. The bool Key_A is declared....

I hope, you can help me.

Regards Efrint

You sure its not some problem in the rest of your application?

yes, i´m shure. If i use the application without this event receiver, everything works fine.

1) your code calls for every type of event, not just keyboard events. you need to check this
2) you have a "!" in your if statement. you know what this means right?
3) 'bool keys' is the snippet you need http://www.irrforge.org/index.php/Keybo ... keys.5B.5D

I tested your event reciever and I can not reproduce a crash, It works just fine here at least the way it's coded.

@bitplane yes I know what a "!" means...

@jam but why does it crash on my computer...I´ve got Visual studio 6, is that the problem?

I create my device like that:

Code: Select all

device = createDevice(EDT_DIRECTX9,dimension2d<s32>(x,y),32, true, true, true, &receiver);

*bump*

does nobody know the solution?

okay this calls for another guess- from the code you've posted so far, you're attaching the wrong event handler to your device.
device = createDevice(EDT_DIRECTX9,dimension2d<s32>(x,y),32, true, true, true, &EventReceiver);

why? i n the line above the create device, i wrote:

Code: Select all

EventReceiver receiver;
		if (DirectX == true)
		{
			device = createDevice(EDT_DIRECTX9,dimension2d<s32>(x,y),32, true, true, true, &receiver);
		}

ohh....i wasn´t logged in....but as i said in my post (as a guest)...

oops yea sorry my bad. still have no idea. try putting some printf's in to your event reciever to track down where the crash occurs

i tried to comment parts of my eventreceiver with "//" out. But even, if the event receiver does nothing, everything crashes.

EDIT: The last line that is written in the consol is: Loaded Texture: #DefaultFont

EDIT#2: If I debug that, i get the message, that there is an untreated exception, an access violation....in this line....

1007E511 call dword ptr [edi+4]

*bump*

EDIT: Even if i use the event receiver from the movement tutorial, i get the same error?! There must be an error in the rest of my code.

I found my error. It was so easy.....I declared my event receiver local in a function. Thank you all for your help
