CC Lure ?

When viewing the lure range of a cc (the white circle around the cc) do troops have to simply reach this line or get past it to lure e.g. if a set of walls meet as a corner and there is the tiniest sliver of white line outside the walls and my giant goes straight for it, will it lure?

Thanks guys.

Giants actually stand a little bit distance away when attacking a wall. So unless the line reaches past the wall a significant amount a giant wont lure CC.

I'm pretty sure a troop has to be completely inside the circle to trigger the cc. So in your example with the wall it would not lure.
