Map generator - how does it work?

[Mqrius]

Guys, I hacked the game code and found the terrain generator.

Code: Select all

10 {spawn [$coniferous_forest] "everywhere"}
20 {spawn [$deciduous_forest] "in blobs"}
30 {spawn [$heath,$grassland,$moor,$swamp,$marsh,$overgrown] "in smaller blobs"}
40 {spawn [$lakes] "in penis shapes"}
50 {spawn [$rivers] "connect rivers"}
60 Supergrid Complete
70 goto 10, repeat till all supergrids are done

This would be true in every other language, but in python it's actually:

Code: Select all

import mapgen
mapgen.setlaketype(mapgen.PENIS)
for sg in sgs:
  mapgen.gen(sg)

Python ftw.

It would potentially be a bit boring to publicize the code, since it might potentially reveal some secrets that can currently only be found by exploring. I wouldn't mind doing it after it's been replaced with a new map generator, though. Except the potential exploration issues, the current map generator is nothing I feel particularly secretive (or proud) about.

Do you mean that your generator makes the same result if not tweaked every time before it's use?

I can tell you that it's written in Python, at least. I also wouldn't mind handing out the code that generates the "patch" shapes (it uses libgd for drawing), if that's what you're interested in.

I am more familiar with Ruby than with Python, but I'll try to copy the algorithms you use. That's some nice trigonometry there, by the way

I was always interested in how to make natural-looking landscapes with a computer. Thanks for getting me one step closer to how to.

I think Amit Patel had some interesting stuff on making realistic terrain since he did it for RotMG(Realm of the Mad God).

Just out of random curiosity. What are you using for your rendering of the scenes, if you don't mind me asking while we're talking about programming. I'm sure it's been asked before, but I never dug deep enough to find it, I suppose.

LWJGL or JOGL, perhaps? Something else even?

As for the map generator, Python? Ewwww... Jk, jk

As for the map generator, Python? Ewwww...

Python ftw man! Or are you just afraid of executable pseudocode?

^ Haha, I don't have a problem with Python, really. I was just kidding It's just that I am so used to C-styled/family syntax, that I just cringe inside for a few seconds when I see Python, as I haven't really worked with it very much. Though, it does what it does well and is a nice language. I just hate looking at it, initially, because of the lack of braces gets to me for those first few moments, so I couldn't help but tease

If I had ever made a cross platform capable game like H&H, I might have even considered using Python as the main language. Maybe. Anyhow, later on when I drop back from C#/XNA back to C++, I am quite probably going to end up using Python as my scripting language for my programs/games.

It's too bad python is too slow for big projects. In some cases, C is 400 times as fast as python. Of course, this difference can be reduced a bit by using psyco (JIT compiler-ish, just import it and it makes your program faster) and numpy (numeric and mathematical array calculations module), but it's nearly always slower

Awesome for scripts, non-time-dependent things, and small programs though
