World Seed not Working
« on: December 26, 2013, 04:04:30 pm »

I'm trying to re-create the world I currently have, but it doesn't seem to be working. I made it with advanced parameters and did some minor changes.

Spoiler (click to show/hide)

When I type the seed in it creates a flatworld without any oceans --> http://puu.sh/5ZtbA.png  instead of my original world. I don't know what's wrong, this is the first time I tried creating a world from a seed. Thanks in advance.

The "seed" merely initializes the random number generator with a fixed value so it will generate a duplicate sequence of "random" numbers identical to what it generated before with that same seed. If DOES NOT define a world. Merely a sequence of random numbers. Now about how those random numbers are used.

1. Generation of mountains.
2. Generation of rivers.
3. Generation of biomes.
4. Generation of caverns.
5. etc. etc. etc.

There's a lot of different elements of world generation that uses random numbers. And if a parameter change is made to the other world generation parameters that causes more of less random numbers to be asked for in a specific area, that will throw off the sequence for the rest of the world generation. So you won't have an identical world to what you had previously.

So in a nutshell, using the same seed will generate the same world ... PROVIDED ALL OTHER PARAMETERS ARE ALSO THE SAME. There are a few parameters that won't cause random numbers to be request, but they are very few and quite limited. So in general, if you want to create an identical world to a previous world you've created, you need to use identical parameters. Can't simply duplicate the seed and change other parameters. That in general won't work.

It's possible you're running into this bug.

P.S. If you don't get this note, let me know and I'll write you another.
It's amazing how dwarves can make a stack of bones completely waterproof and magmaproof.
It's amazing how they can make an entire floodgate out of the bones of 2 cats.

I fixed the problem. I forgot to copy the temperature parameters. Thanks for the help  :D
