what is a random gen world? SEED

[Redarmy]

I get random worlds,but im hearing all this about naming a seed...the wiki doesnt make clear what it means...

The random gen map is a randomly generated world created using your game name as the seed.

When a player opts to play using Random World Generation, the name they give the game decides how the terrain will be generated and which Points of Interest will be placed where. For example, a game using the name "Survive PvP" will be completely different from a game using the name "Survival PvP", both of which will be different from a game using the name "7 Days to Die".

How does the name i give decide the terrain????????

i was playing a map called voyuz or sth like that,im starting a new game,and after looking at Neebs gaming 7DTD i wana play sth like they have.

Any ideas?

The name (seed) you type in when creating a random gen map is converted into a numeric hash and then plugged into the map-making program. Using the same seed will create the same map over and over again, which is how people share them.

If you want to play on a map you've seen, (you have to make sure you are playing the same version of the game) just find out exactly what the seed was that they used and type it in. Be sure to include all caps and spaces. The game should generate the same map.

I kind of follow you.

So this works for single player? So i need to be online? cuz SEED info is stored somehow?

Note - The map name you see is NOT the same as the seed.

Yes, this works for single-player. I do not play MP, so I cannot answer any questions about map handling and servers.

No, you do not need to be online for the map-gen to work.

The seed info is converted to the hash for use by the map-gen program, but is also saved in an info file when the map is created. You can find it on your machine here:

\Users\"YourMachine"\AppData\Roaming\7DaysToDie\GeneratedWorlds

In there you will find the folders for all the gen'd worlds. Open the folder and the file GenerationInfo.txt will tell you the seed you used to create the world.

As explanation: The world generation is not random but procedural. Computers have a hard time creating "real" random numbers. But they can calculate what is called pseudorandom numbers. The random number generator is fed with a seed as starting point and generates the same sequence of random numbers again and again. The map generation takes this as input and generates a map from noise. It is not required to understand how that works but its an interesting (and complicated) topic.
To summarize: the seed is the initial state of the pseudorandom number generator. The map is generated procedurally from it. The same seed leads to the same map (as long as generation algorithm is not changed).
