Zombie spawning on roof

[ancient parrot]

Like the title says, I was out looting in singleplayer and heard a zombie nearby but couldn't find it. I moved away from the house into the road and looked around, checked the woods by the house, nothing. Then happened to glance up and there it was, on the roof. Thought it might be interesting to see if it would take fall damage so I ran up to the house trying to coax it but it seemed to not be able to move past the edge of the roof. So it seems there's something that's allowing them to spawn up there but there's some kind of boundary that it won't path through. I was able to shoot it and kill it.

Had another one happen on another house

There supposed to spawn in the house but it clips and puts them on the roof

I only know this because I increased my zombie multiplier while I was in a house and it had an animation of spawning and then it elevated to the roof

Well that's good to know. It also brings up the question as to whether zombies will take fall damage. I can't think of a situation where they would technically be able to get high enough to take it, but it's an interesting question

They can climb.

I would assume they take fall damage. I had a few of them on a fence I destroyed. They fell from that and died.

I didn't figure that would cause fall damage, I have climbed fences on multiple occasions and never taken any fall damage so I just assumed it wasn't really a thing yet/at all

Might have been collision from the broken wood
