Tiny Islands
« on: September 08, 2012, 08:21:26 am »

Is it possible to generate a world with an island small enough that it fits in a 4*4 space, so that it would be absolutely surrounded by visible ocean? Would this mean nothing could arrive?

I think island generation has actually been tweaked to prevent this, since it prevents any land creature from leaving your embark tile (which is why you want it, right?). You could try fooling around in custom settings, though.

I've tried to do that in perfect world but minimum brush size is one maximum embark size.

This is very possible and with regularity.

I made a guide.

Do you know what parameters make for lots of little islands?

Depends how you mean. In a normal looking world I'm not sure how to get small islands but if you follow the link I posted you'll find some parameters that will get you a couple per world. Sadly even when you have a world of islands like in the screenshots most are still larger than the local view.

How can you generate your own parameters that make small-island-festooned worlds with, say, high savagery or different shapes or biome distributions or otherwise not exactly like the maps you have?

To get high savagery you'd need to use a savagery map. If you pasted this onto the end of the parameters I'm using all the islands should be savage. This could lead to a few savage only creatures on embark but you won't get more spawning on the surface.

Biomes are far trickier as we don't have control over the temperature map. You'll have to make your own rainfall and drainage maps using this as a guide. It's important to leave the right hand column alone in all this / give it reasonable values so that the civs can spawn. I suggest you use PerfectWorld to gen your maps. Export them and copy the bits you want.

As for different shaped islands you'd want to use different seeds. The same goes for biomes to an extent. As I say in the guide: different history seeds with the same world seed will get you identically shaped islands with different stones.

Hopefully I've answered your questions. I can provide some parameters if you have something specific in mind but it'll have to wait until tomorrow now as I've off to bed.

No, I was just wondering in general how much those parameters were screwed up by modding, changing seeds, or whatever. May your dreams not be tainted by forgotten beasts.

The same parameters will give different islands with modded raws. I don't even think they will give those exact islands in the current version. I describe how to use the parameters to find your own here. Searching for them is pretty straightforward but dull.

Cheers.

As long as the general parameters work, I'm peachy.

It is also possible to just construct embarkable areas in the middle of the ocean using mostly DFLiquids as well:

Disable bottom layer when generating the world, when you use 'Just Embark' to embark on the ocean the units will spawn in rock in the lowest top left corner tile and not die. Construct the landmass as needed using DFLiquids, modify tiletypes as needed with DFHack tiletypes command. Abandon and re-embark again with 'Just Embark.' For the volcano I made, the under-ocean magma had to be placed after embarking the second time as the ocean tiles overwrite it upon embarking.

Example island challange; I've made it to autumn...
