Is there a reason to want to have this tied to walking on the ceiling? You could have other use cases, such as actors that only want to stay under the open sky and will not enter buildings.

Even then, CANTLEAVEFLOORPIC itself is rather shit, it's legacy baggage from Hexen that was never well implemented.

In other words, how is it faked?

They use NOGRAVITY with constant distance checks, they cannot climb 'stairs' on the ceiling or other stuff and if they lose touch by moving into a sector with a higher ceiling they just drop down.

Then what is it supposed to be, flipping the entity and its gravity?

There's no such thing as ceiling walking - even for the stalkers it's all fake.

I assume the same as [c]+CANTLEAVEFLOORPIC[/c] but for the ceiling. Could be useful for ceiling-walking enemies like Stalkers from Strife.

What is it even supposed to do?

[c]+CANTLEAVECEILINGPIC[/c]

Why not have this feature?
