Enemy pathing diagonally?
« on: July 15, 2016, 11:51:25 pm »

Can enemies path diagonally? I am putting a ceiling on a tree farm and it will look like this (the top level):

X: floor (current Z-level)
W: top of wall from previous Z-level



Code: [Select]
WWWWWWWWW
WXXXXXXXW
WXXXXXXXW
WXXXXXXXW
WXXXXXXXW
WXXXXXXXW
WWWWWWWWW


Is that totally airtight?

Enemies can path through diagonal holes in your wall, yes.

So if you took off the corners of a square enclosure, they'd pop right through.

Enemies can pass through build fortifications diagonally from above, because build ones do not have a floor on top, while carved ones retain the intrinsic floor provided by the original wall, regardless if that wall was built or natural.

Somewhat surprisingly, flying enemies can also go through this:

z1:
++W
++W
++W
z0:
++B
++B
++B

W=Wall
B=Raised drawbridge.

They'll appear on the floor on z1.

Assuming z1 has a roof and assuming '+' is a floor, this is rather surprising. I assume they'd move from z0 just outside of the bridge diagonally upwards to the floor on z1?

I haven't been subject to that one, although I occasionally get the same situation (although the wall is replaced by a floor) when I have to kill FBs with cave-ins.

I don't really consider it trivial. It's about the same rank as the horrible up/down staircase unrevealed access from diagonally below "feature". Suddenly your "secure" fortress is invaded from somewhere unknown by something more or less dangerous (let's hope for a giant cave swallow!).
