Stop zombie spawn if an area is fenced off

[Shift 25]

I love the game but i dont really like the zombie spawn mechanic. I think its lame and unrealistic when you just turn away for a second, turn back and there's a zombie when he clearly couldnt have gotten there in the time you spent looking away. Also it would be cool if players could clear and kind of take over a small village with a couple houses. I've been thinking what can be used to stop zombies from spawning and i decided that using some kind of flag or any other object that makes zombies stop spawning in a certain radius around it is lame and unrealistic. But a realistic way would be to fence off an area. I mean in real life zombies would have to walk over to your place from some place else if you cleared your place from zombies, and obviously they cannot walk into a fenced off area! I'm not even saying prevent the spawning of zombies entirely, like if there's a location with like 2 houses and 2-3 zombies spawning, make it that if you wall off the area around one of the houses or both of them, they spawn just outside the walled off area (i'm not sure thought if the game engine would allow for such script). Now obviously there should be a limit on the area that can be fenced off and free of zombies so that people dont fence off whole towns and military locations, the area should be quite small, just enough to fence off like 2 adjacent houses. Maybe this should not work at all in military areas, i'm ok with that.

Also it would be cool if zombies spawned in surrounding forests and roads and walked into locations instead of just spawning in the middle of a cleared town etc. that way a group of people would be able to keep a decently sized town zombie free by killing all zombies that are walking towards it, when they are no longer available to defend an area the zombies would walk in and populate it as usual.

yeah roaming zombies would be great, as would bases/lights/sounds/cooking smells that attract them
