Zombie Bunker question A20

[[AV8R]Treekin]

Hello! I've been having an issue with my bunker build. We're pretty early on in our playthrough on a server I have set up, and I've built a bunker with an underground entrance. My problem is that The zombies are completely ignoring the bunker on hoard nights and going for my hatch that's 20 blocks away to get into my tunnel and get us from there. Is there something I'm missing? Do I need to make a series of doors that we need to close on hoard nights under ground so they come for the bunker instead? Or do I abandon the tunnel entirely and make a bridge in the air with removable wooden blocks? I've also considered doing the arrow slit exploit around the hatch so they don't path to it, but I don't want to rely on something that will eventually get patched. I'll admit that I'm pretty frustrated that the zombies are able to have some kind of precognition about how to get to me and immediately ignore anything to do with the bunker. Thanks!

Update: Thanks everyone one! I've extended my tunnel and added several doors in it. I've also encased the tunnel in cobble and eventually cement. I also have the entrance inside my base's walls which will have doubled airlock style doors. I'll see how this does and report back!

Probably 20 blocks is not enough. They see easy entrance with only hatch blocking. Dig tunnel further.

You’re wise to do so. In fact, the arrow slit exploit has already been patched.

Last I knew, zombies factor in 40 blocks away when doing their pathing. They are looking for the path of least resistance, so going 20 blocks away with just a hatch to stop them may be interpreted as less resistance than your bunker.

It might be the number of doors. The entrance to my bunker is 20 blocks away, through a Door located in a rail walled building. In the center of that is the hatch going down. 15 Blocks down is another door going back towards my bunker. Another 20 blocks back is another door into my main bunker.

I keep all doors/hatches closed and the zombies have never gone after the entrance building. All the walls/ceilings are at least cobblestone.

Hatch should be further away.

The exploit still exists with many new blocks TFP added.

Arrow slits = no longer able to repair traps through them (good one tfp). One could use the new double pole block having same hit points and allows repairing through the block.

Those new little corner posts that look link a spike (dont recall the name).

I made a pit around my base 4 blocks wide and 3 deep, then placed those blocks so the points faced down. I can sprint across them without falling into pit but zombies wont go over them. They go all the way around to where the entrance is to the traps and get blasted.

just build high or sit up in a freaking barn or a ♥♥♥♥♥♥♥♥ tree. They need to threaten high up bases! These devs omg! Every zombie should have a potential explosive ability!!

so a feral flaming spider zombie that has their old wall climbing ability and has a demo charge strapped to it? what could go wrong?

In our experience, the zombies will focus on the weakest (mathematical) point. Doors are one of their preferred targets. Hatches even more so. Even if they're vault hatches.

Couple quick thoughts/suggestions:
1) If you want to stick with the hatch system you're using, add several intermediate vault hatches to your tunnel on the way down. (E.g. Hatch, five sections of ladder, a landing and another hatch, etc.) Concrete the whole hatch tunnel so they don't dig the dirt or side wall and bypass the hatch, and if you have the material, upgrade that concrete to Forged Steel. Whether or not that completely stops them from pathing that way or not, it will most likely slow them down to the point where you can get through the night and then clean them up.

2) If you don't have the time/material for that,.....then just for Horde night, before it starts, either remove/destroy your primary entrance hatch and replace it with a concrete plug, or cap it/cover it over from the outside with a couple concrete blocks. If I was going to use this strategy, I'd remove the hatch, plug it with a concrete block, and then do the same for the next several blocks going down. Essentially plugging the top of the hatch tunnel with several concrete blocks.

Either of these options will give you both a chance that they won't get through before morning, AND (mathematically) that the pathing software might calculate that the hatch tunnel is now NOT the easiest option, and path the zombies at your bunker from the surface.

Good luck!

They choose the path of least resistance. As stated above, add a couple more hatches or doors between you and the back door so it looks harder for the zeds. Then they will choose the door you want.
