[2020] Zombie pathing Help Required

An important note that I'm not sure if was mentioned yet or not, Not all zombies follow the exact same routine- There is built in randomness, and part of that randomness is that sometimes they just start attacking the firs thing they run into without bothering to walk around or take an alternate route.

And if any zombie starts randomly beating on a wall, it can attract the attention of others as suddenly that spot is becoming a weakpoint under the attacks of that zombie.
