Looking for some suggestions...

I’m looking for suggestions. I have a structure with a roof like the one pictured below. There is a set of stairs from ground-level (Level One) to RoofPart A. All three parts are actually attached to create a single roof object and are part of Room 01. Though there is a one meter height difference in A & C to B, but they are all on Level Two.

Ok, here is the problem. The AI characters will traverse the roof with no problem, except they will only go down to RoofPart B and will not go to RoofPart C or back up to RoofPart A. The player-controlled character has no problem with any part of the roof.

Is there a better way to do this (so the AI follow correctly)?

Here is another view (for clarity's sake).

There is probably a collision detection problem. Look at the map in Igor in the center top window. If there is a blue line across the stair edge, the AI will think it's a wall and stop. They seem to be one-way, like the polygons are one-way, so the AI can walk from A to B, but not from B to A or C. A solution is to cut out the wall at the stair edge as a separate object, then tag that as non 2d collidable. It then won't generate collision detection, but will still be 3d collidable - i.e. bullets will still hit it.

Thanks cobaka! That's what it was. All is right now!
