Some "terminologies" i would like to know more about
I have been wanting to ask these questions for years now.

1) In the sandbox setting for zombie, in the description for "respawn hours", what exactly is a "cell"?

2) In description for "respawn unseen hours", what exactly is a "chunk"?

are these one single tile? or a square shaped area with player as center? Or just a fixed place, where i can cross from one into another simply by moving one step over the border?

Think Minecraft: The game only "loads" in the chunks you can see to keep everything smooth. Entities only exist while loaded. You move, things load and unload from the world.

Far as I recall, "cell" is just a collection of "chunks".

The zombies are always "there" though, meaning they'll still react to sound cues and wander about. Once you approach their render, they pop into existence. Migration and assorted settings affect this.

Not exactly, better see the post I linked, everything is explained in detail there.

Seems I'm correct enough to explain it simply, I don't know what you're talking about?

You talked about a render perspective and a cell being a collection of chunks, which for Zomboid is not correct.

The map is divided in 300x300 cells, the chunk is a 175x175 square if you in the center. Both interact for spawning mechanics, a cell is not a made out of chunks.

The game knows at every time how many zombies should be in any cell and spawns them based on the number of hours lapsed, but when not loaded they are mere statistics.

Seems like any multiple of 175 doesn't fit inside 300. What an odd division of map pieces.

Sure, but that's also in the context of minecraft.. I think you flew way above that point.

Homie was asking what it was. I explained it simply. If you cannot explain it to a child, do you really know what you're talking about?

Yes, we can just slam out some links to massive walls of text that were painstakingly typed out. Or we can take a moment to talk about things as they come up..

A cell IS made out of chunks. Your little link even says so.

I don’t know how the programmer worded it

But for me

A cell would be a individual tile, like that you would dig a furrow on.

A chunk would be a radius of cell, infact you can see it when multiplayer server dies while you are in game. You will be able to drive and hit a black edge. In all directions that is the end of your chunk.

Sometimes maybe

lol

A zombie is registered inside your chunk, to one of the cells. But he hasn’t rendered, now you fill up at the gas station on this chunk while looking away from his cell and he decides to exist :D

thanks for the link - i've been looking for some info about the zombie spawn settings - looks like this should help :-)

Been having some interesting times playing Survivor with real zombies (or Apocalypse with multi hit and low rear vulnerability - same deal lol) - but then playing around with Population Multiplier and Population Start Multiplier - even when starting them low, after a while you still end up with the zombie apocalypse - but at least you get can a little period of relative calm for a few days before getting horded to death lol :-)

Yes, but this is not Minecraft. You cannot slap how things defined in one game directly to another.

If you even do not care to read anything and will throw incorrect answers which do not respond to the question, do not respond at all.

That wall of text was clearly explained by the Devs and formatted, so you can directly to the definition you want.

And no, a cell is not made out of chunks.

Yep, this is really helpful, I've been messing with those in order to understand how they work and ended up turning off zombie respawn all together in CDDA, as otherwise I feel like I am always fighting the same zombies and do not make any progress.

Now they migrate, but at least I know the overall number has been reduced.

one thing that i did find that is quite sad, is that if there are no zombies - either by starting using the None option, or by using the debug option to Remove All - zombie spawn can pretty much never be reenabled - no matter what you do to the sandbox settings (using the mod to change them during the game), or even if you spawn a zombie horde, you will still never get new zombies - you can't even spawn zombies in debug using the regular spawn, only the "Spawn Survivor Horde" option

i guess this is because the Population tab in Sandbox settings changes some backend variables that can't be changed back - or are maybe baked into the map - and i guess Remove All does the same

but now that i know about the zombie viewer for debug mode, i shall play around and see what happens - maybe i shall be experiment with a "Patient Zero" type scenario - starting with as few zombies as possible and maybe letting them double every day, or hour - for some exponential existential terror lol :-)

It's an analogy. Strange concept, I know, but it helps grasp the meaning by connecting two unrelated things.

Air is like water; It's fluid. Air is not water.

Minecraft is like Zomboid; They use certain tricks to not melt your PC. Minecraft is not Zomboid.

If you do not care to explain it, don't bother to link it. Same logic applies there too.

It is tho.
