Well it wasn’t even the Wander Spawns that I was having issues with. My issue was having a city cleared of zombies, walling it off so nothing could wander in, yet certain enemies would still ‘spawn’ inside the city walls anyway. The main culprits being, animals and their zombie counterparts, not the human zombies.
To give a more accurate description, I want you to picture that there is a city, fully walled off. Imagine it’s surrounded by the post-apocalyptic version of the Great Wall of China, but filled to the brim with all sorts of defences so not even a fly could sneak its way in, because if it tried it would be full of both laser holes and lead bullets.
Now imagine you’re in the centre of that little city, with no zombies currently inside it, because you’ve found them all one by one and smashed their skulls in, burnt and butchered their corpses so they’re not going to pop up again. Because the map is being played with Static Spawns on, you know that there is no way any zombies will get in to your new city home, which they won’t.
You’re making your way down town, walking fast, no faces pass as your home bound, then suddenly out of nowhere, you’re under attack by a pack of Grim Howlers that were lurking near your home! How did they get in to the city? The city was cleared out! Maybe you just missed them whilst clearing out the city?
No, the answer is that certain enemies don’t follow the static spawn rule, they’ll spawn when they like, where they like, without caring that it makes no sense for them to be there.
I mean sure you could just set up turrets everywhere inside the city to kill any enemies that do spawn within the walls, though you’ll have a hard time sleeping with gunshots randomly going off whenever something spawns close by, or happens to somehow get close to a turret and blow it up. Though my own issue, a minor one as it is just because I’m awkward, is trying to clear up the messes it all leaves behind. You’ll find that surrounding you home has been littered with blood and corpses each morning you wake up, such a pain to deal with!
In regards to Wander Spawns turned on, I don’t know if they’d magically phase through the wall or not if you’re too far away from the city, but as Kevin earlier it would require a lot of script magic and slow the game to a crawl if a horde were to attack whilst you were gone, so this dream is basically busted. Living in a tower/Basement seems to be the way to go.
