Hello fluffy wamblers, unicorns, and other friendly creatures inhabiting these forums! I am looking for some help generating a world by changing the world_gen.txt file. I've tried using the wiki but don't really understand what I'm doing. My changes usually end up in endless world rejection .

I'm after a volcano next to an ocean, preferably in a cold/occasionally freezing climate, high savagery ideal. I've never dealt with aquifers before, but believe I am up to the task, so that shouldn't be a problem. I've genned a few worlds but the volcanoes are either on islands or in the middle of mountain ranges. So my question is, what should I change to ensure more volcanoes, but not saturate the entire continent with them?
Secondly, is the FPS improvement of rolling 2 or 1 cavern over 3 significant?

Thanks very much for all your help!

Basically what you want is to whack in a large number of minimum volcanoes. You then set volcano X/Y variance to 3200. You then let it gen. After 100 or so rejections you have the offer to just accept the next generation regardless, potentially making a legends only world, but i have never had this occur. These worlds have flat volcanos, perfectly cylindrical volcanoes, island volcanoes and clusters of surface magma pools meaning i had no open land or ground to work with. It was insane and terrible.

Set mineral scarcity to 100 and give yourself more embark points while your at it.

Haha, this is exactly what I don't want! Cylindrical volcanoes have to be the worst part. I just imagine them looking like a giant, obsidian tube worm. Great .

[Wannazzaki]

The variance is part of what makes them spawn in absurd places, and its why you make the minimum number greater. Its all about increasing the odds. Anyway that's what i would suggest.

[Russell.s]

Thanks . I'll give it a try.

[Russell.s]

Okay... this is a silly question, I'm sure, but which line exactly should I be altering? I see the minimum volcano number, but which is the x/y variance?

[Wannazzaki]

Do you not have the custom world_gen file that lets you generate with advance perameters within the games world gen function itself?

[Russell.s]

I never thought of using that... I've just been editing the raws directly. I'll have a play. I feel silly

[Wannazzaki]

Just in case you don't have the custom world gen file, myself being not so omniscient, here it is. http://www.megaupload.com/?d=UH8NOOPX

[dr_random]

What exactly does the number of embark points do at World Gen?

[Wannazzaki]

Lets you start with more embark points?

[dr_random]

Lets you start with more embark points?

There are lots of them anyway.

Those parameters control the minimum number of squares for each category that must exist for a world to generate and are responsible for the majority of any rejection. Setting them to zero means that a world will not be rejected because of an inability to place those squares and should drastically cut down on the number of rejections you receive.
