Using Scroll Wheel

[The_Imp]

I'm trying to use the scroll wheel to zoom the camera in/out, and having searched on forums it appears I should be using the Z axis, but it doesn't seem to be working.

Here's the method that's causing me problems:

Code: Select all

void AvatarFrameListener::mouseDragged(MouseEvent *e) 
{
	if(pan) {
		Vector3 trv((e->getRelX() * 400.0), (e->getRelY() * 400.0), 0.0);
		mCamera->moveRelative(-trv);
	}
	
	Vector3 zv(0.0, 0.0, (e->getRelZ() * 400.0));
	mCamera->moveRelative(zv);	
	
	if(rotate) {
		mCamera->yaw(Degree(-e->getRelX()) * 200.0);
		mCamera->pitch(Degree(e->getRelY()) * 200.0);
	}
}

The pan and rotate works fine, but the zoom does nothing. Any suggestions as to why? Thanks.

Just realised that scrolling the mouse wheel doesn't cause any form of dragging. Put it in mouseMoved and it works fine. D'oH!
