how do I retrieve map and game seed from a .Civ6Map file?

[treethry]

Hi everyone,

I have a map that I generated in the world builder(but I have not edited it at all) and I just wonder how I could retrieve the map and game seeds from it. The mod I tried to use to play the map resulted in my settler spawning on top of another one(it is this mod http://steamcommunity.com/sharedfiles/filedetails/?id=876864462) so that is not a solution. I believe that because I didn't edit the map that there must exist a map and game seed that correspond with the map I want. retrieving these seeds is my preferred method of solving this problem, if it is at all possible.
here is the map in question

Thanks in advance!

it seems like I might have posted this thread in the wrong category I'm not sure, if so then could it maybe be moved to the appropriate place if possible? Thanks in advance again.

If you try playing the Map in Multi Player you should be able to retrieve the seed information that way.

Wait, that doesn't only work with saves?

Can't you start a game with the map and save it then open it in multi-player?

Well I tried this via the mod but the seeds I got didn't allign with the map I wanted. Maybe the mod ignores this parameter[seeds] or something else was off but I'm inclined to believe the former.

How to regenerate a given game @ the beginning of turn 0
It is actually very easy to extract the game/map seeds.
1) go to the folder where your game is saved. Documents\My Games\Sid Meier'sCivilization IV\Saves\single
2) copy the saved game you need and paste it into the Saves_Multi folder.
3) create a multi player game using the saved file, and it will show all the information.
PS: in order for the game/map seed to work, you need to adjust all the settings according to the original setup. map size, world age, number of players/citystates, resources etc.... however, you can change the difficulty level freely without interrupting the map.

there's a bit of a difference, I'm trying to get the seed from a civ6map file rather than a civ6save file, this workaround doesn't work with that filetype unfortunately

maybe I don't understand the problem too, but why (and how) would the seeds be saved in a map file ?

well I was restarting on the world builder until I got a good map and I thought I'd use the mod to play it but the mod seems to have too many issues so I decided that I'd try to retrieve the seed for the map via the multiplayer trick by first creating a save with the mod that uses the map but that didn't really work. So now I'm trying to retrieve the seed from the mapfile directly somehow.

If you copy the single player save into the multiplayer save folder, then load that game for multiplayer, (lan),
when you join the room it shows the game and map seed.

Now, whether you get the same start point, I don't know.

Otherwise, you have to dig into the hex coding of the savegame (bleah)

Edit: I had to put all the civs back in, in the same order, to get my same start point.
The map was exactly the same, but it gave me a diff start point.

I'm going round 2 with the above seeds, have same start point, but put the cities a bit better.
So, the multiplayer trick does work to get the map, start spot, well, you gots to fiddle with that.

those seeds don't seem to generate the map I wanted at all... the (changed)settings for my map are fractal; standard size; high sea level. Thanks for trying to help though!

Keep in mind that the seeds are shown in reverse order in the multiplayer interface. That is, the map seed is shown above the game seed. However, when you create a new game, the game seed comes before the map seed. If you mix them up, then of course you'll get a different map.

I recovered seeds from a start that I really liked and recreated the game about a dozen times. I always got the same start on the same map. I had to select my civ, which I had also done when creating the initial save. I left the others at random.

I've done some tests recently and what I found was that in order to reproduce the same map, resources, and starting location, a new game HAS TO have identical
- Patch level
- List of Add-ons (including DLCs, but scenarios have no impact)
- Starting Player (the list of AI players remains constant, IF the other constraints are respected)
- Map type
- Map size
- Map tuneables (Sea Level, Wetness, etc)

The only things that can vary are:
- Difficulty
- Pace
- Victory conditions

So, unfortunately, most of the seeds ever posted on the forums are worthless, unless you happen to run the same patch level and same mods & DLCs as the submitter.
With different patch level and different add-ons you usually end-up with the same geographical features but with different resource allocation, starting locations and list of Civs (which may be why you end-up with differing starting locations since the placement scripts would try to position different civs differently)

Well all I really want is the map seed, so this all isn't too bad

sorry, the one I gave was for my game, not yours.

I just showed how and where to get the seed from any savegame.

edit: to get the same start location, I had to put the same civs in the same order.
map was otherwise, identical.

Currently not home, I'll check if it works today. Thank you for your help!

could you perhaps post the seeds it yielded for you? I'm not getting the map I wanted with the method unfortunately.

 

[Canadian Bluebeer]

Ok, no, there is no seed in the map file, only the saves.

I just took a look at the file in the op.

Map seed generates the maps and resources, game seed is where everyone starts.

(and I think I"m gonna have some serious fun with maps now) hee.

Edit: ok, I've got 2 maps up that give the same stuff each time, but gods is it annoying to do.
CS placement on custom maps is weird, as in won't work for me.
Player or Civ does work. CS just gets skipped. dunno why.

I could take the japan map and hunt for the the various starting points, presuming they are there.
In the one I generated and had to fix, most of them were missing, and some placed in strange places.

Mind you, I also had YaMP running and I think those scripts confused the placements. (as in, where the civs would spawn, there wasn't always a spawn point saved in the map. odd)
