AccessViolantion in

Dr.Fred · Post by **Dr.Fred** » Tue Oct 14, 2003 8:44 pm

Everytime I call this funktion:

int PortalSceneNode::cullBoxAgainsView (const core::aabbox3d<f32>& box, const scene::SViewFrustrum* View)
{
	bool clipped = false;

	for (s32 i=0; i<6; ++i)
		switch(box.classifyPlaneRelation(View->planes[i]))
		{
		case core::ISREL3D_FRONT:
			return 0; //compleatly outside
		case core::ISREL3D_CLIPPED:
			return 2; //partly inside	
		}
						
	return 1; //compleatly inside
}

I get a AccessViolantion, after the "classifyPlaneRelation" call.

Ohh, I forgot to enter the rest of the title.

maybe View is null?

What about planes? This smells like a pointer messed up.

++i or i++?

@guest
it's the same

@Saalen
I think that is ok.

No, it's not. But I don't want to do nitpicking here.

Cheers.

Is View->planes[] a 0 or 1 based array?

If your compiler doesn't allow breakpoints and debugging, try adding output statements to figure out where and on what loop iteration exactly it is blowing up.

To me, it seems like what Saalen stated, a pointer problem of trying to access an element in the array that doesn't exist.
