What’s That Red Stuff?

Do you see it, right there? That’s the problem. Herein it shall be explained why and then how it is solved.

So we’ve had some talk about the overworld lately and the old post about world map generation still stands. Now we’re dealing with the details of living in it, of filling each biome with appropriate textures and objects. This is proceeding rapidly.

Steampunk Central America: Adventures in Sort-of Verisimilitude

Well, we just wrapped up a two-pitcher lunch at the Sewer Brew Pub with a fan (hi Kris!), so you  know that means: time to write a blog post! So Daniel has been cranking through biome stuff and asked- no, let’s start this over.

The sky above Vancouver was the colour of a television tuned to a dead channel. Daniel entered the gently cultivated chaos of the art room and recoiled slightly. The chaos recoiled slightly back at him. 

“After Steampunk Colorado, what’s next?” — Oh, well then: we could do a desert. Lots of bones, dust, salt, jagged rocks. No? Really? I thought it’d be pleasant. Then perhaps a swamp, something lovely; Lots of plants, molds, miasma, large insects, fevers. No? Not a swamp? If we must then, let us set our sights on:

Steampunk Central America

White sand beaches, tropical forest, volcanoes, cenotes, deforestation, strange statues buried in the sand at the low elevations and giant, scowling basalt heads at the higher; beetles grazing in tropical meadows before wallowing in warm streams. It’ll be lovely. And we still get those fevers in.

It starts with a palette of colours, the right colour for the right sub-biome from the top of the topology to the bottom. It’s all layered like some kind of terrible cake full of dirt and growing trees. Below is a quick sketch I did to give an overview of what could be going on in a roughly Central American biome set:

Literally the broad strokes.

Literally the broad strokes. (And with apologies to our Central American readers — this is all about capturing a certain interpretation of a feeling of reality without being much arsed to be real reality. Which is about what CE is doing in general but with more steam engines. Would it help if I said the word “verisimilitude” here and waved my arms around? Good. It made me feel better too.)

Erupting with enthusiasm.

I’m erupting with enthusiasm for top-down concept maps for biome generation. (If you enjoyed that, I’ve got more. So many more. Er, to clarify: I’ve got both terrible puns *and* biome concept art.)

Biomes of Steampunk Colorado

Last time we talked about biomes back in February, Mr. Whitman had finished a framework for terrain generator and had implemented a few test case biomes which we have been using in-game for a while just to give us something to hack on to test the features we’re after. This small set of biomes has been the backdrop for a ton of our screenshots lately. You may have noticed a recurring theme of pine trees on a field of green grass with some lakes.

We’re going to start mixing it up in the next month or so. The system we’ve implemented runs on a concept of two or three specified biomes on a given game terrain map (the playable area in any given colony).  Some examples might be a “high prairie” (aka “Steampunk Yellowstone National Park”) biome, a tropical rainforest, a desert, or the Novyrussian taiga.  Within these biomes, we have subcategories of smaller environments that we call “mini-biomes” or “sub-biomes”.

For our high prairie example, these include the prairie highlands, canyons, conifer forests, aspen forests, or craggy hills. We have some heuristics for determining where these mini-biomes should go within the map.  A fairly simple random walk for determining river directions, which gives us gravel beds, canyons, and actual rivers, and Perlin-based determinations for where forests or hilly regions are placed.
