Finding how it is related to the tree being split is a good catch. You've probably seen, that the chunk class has a debug method that generates a .dot file which can be processed with graphviz' dot tool to see how the tree looks like. Maybe that helps in this case. > I was hoping that that would solve the other problem of 'falling through the > stairs'.

The symptom in mapedit seems to indicate the the bbox of the stairs is not correct. mapedit does not have a render loop, but instead redraws just the space covered by an object, which is determined through it's bounding box. And if I place a staircase object onto the map, it does not show up at all, until I cause a full redraw (by temporarily obscuring mapedit with another window). I believe what happens it that the offset of the individual parts of the stairs is not taken into account (properly) when generating the bbox. It's composed of 16 pieces, each with a size of 16x48x8. These are offset in such a way that the staircase comes out. I suspect this results in an overall bbox of the same size, at who knows which offset instead of a bbox that incorporates all the part of the staircase. I haven't looked at the it in a debugger, however, so my guess might be wrong. > I'm done for the night, but my plan tomorrow is to continue looking for the > real fix to chunk::find_chunks.

If you like you can also continue to look at the 'falling through stairs' issue, as I believe the two problems are different. (Wondering if the shadow stuff uses a find_object that's not used elsewhere, or with flags not used elsewhere, which could explain why we don't fall through the ground everywhere). I've got more stuff to look at, more gfx and models to create, so I'll be busy too without getting in the way :-).
