Hello all,
I'm an intermittent geek, which is to say that when the mood strikes me, I'll dive into sims like this, and then I'll come up for air for several months before coming back around and diving in again.  I haven't even downloaded DarwinBots yet, but it looks extremely cool - mostly I've been playing with something called Darwin's Pond, and enjoying it immensely.

Apart from Alife type things, I'm a mom, henna artist, SCAdian, and general geek-of-all-trades - especially if they have pretty colors.  From the look of things, Darwinbots have pretty colors, so I should be good to go.

But here's the real reason I'm coming to the forum.

I came up with an idea for a sim/game last night, and based on other sims I've seen, it should be workable, but I'm not a programmer (okay, I guess I'm a geek-of-MOST-trades).  I do not have the FOGGIEST idea where or how to get something like this going.  I was wondering if DB has anything in it to simulate terrain, or if the bots could be programmed for different food types, sizes, speeds, all that good stuff.  Failing that, I was wondering if there are any programmer nerds around here with free time to play around with the concepts I'm working on.

It's one of those things that starts with simple parameters - although there are probably more of them than in a typical sim of this type - which you can combine to get a lot of complexity.  Users could build plant and animal lifeforms using those parameters, then throw them into the system and see what happens.  Since I was thinking of having different terrain types as well, users might even be able to build their own environment for the lifeforms to run around in.

It's mostly meant to be a food-chain simulation, but I'd also like to apply natural selection to the environment - except I don't really know how.  My idea varies from the other sims I've encountered mainly in sheer number of parameters, allowing for a more complex environment and, if I can figure it out, more realistic creature behavior -
if I could get some idea of how to give the animals the ability to vary their speeds, for instance, based on terrain or threat or whatever, that would rock.

Rather than spam you all with the details, I should probably stop here and see if there is any interest at all, and any advice or assistance here for the asking.  This looks like it's one of the ONLY active forums I can find on Alife, so I'm hopeful that I'll at least get one or two replies back.

Cheers, and it's off to download DarwinBots!

Hey PeaceHeather, it sounds like a great idea but I am sorry, sort of in the same position, I have no idea how to program really, starting with Microsoft Visual Basic but cant really do anything but that.

Yeah, not much activity on ecosystem type ALife.  You could maybe play with Darwinbots to get it to do what you want (shapes for terrain, program some bots or find some to use) but ecosystem sims have been unstable in the past.

If your ambitious and know db code, you could try to create a shepard bot which forces bots to evolve for specific niches.

A whoziwatsis?

And, isn't DB already something of an ecosystem sim, since you have plant and animal types?  Or maybe I'm misunderstanding the term.

There are at least two extremely simple ecosystem sims I've seen that work okay - Darwin Pond, and another one called Bugs or something like that, which uses ground color to indicate plant density and water bodies as physical obstacles, kind of like shapes here in DB.  As for DB itself, I really only started running a couple of sims today, so it will be awhile before I do any programming.  And it doesn't look as though DB will allow the terrain types to be anything other than universally "passable" or "obstacle".

Oh well, wish me luck!  If I could find any other alife forums or communities that didn't look like they've been dormant for the past 8 years, I'd be able to ask around further, but... *shrug*

Thanks!

Hi and welcome!
Funnily enough, I played with most of those ideas in a Java version of DB (Never quite worked out in the end   ). I think terrain was being played around with in DB3, but was given up along with 3D and a whole bunch of other ideas.
by 'plants', a 'bot', or cell, that is fed by the environment is meant, while by 'animals', a cell (or sometimes multicelled organsim) that eats other cells is meant.
I'm sure you could get a simple food chain going using a veggie that has shell to stop body feeding and encourage energy feeding, an energy-feeding vegetarian bot, a predator bot that eats body mass so it can only feed off non-algae, and a bigger predator, probably a multi-celled organism as they should be immune(ish) to being fed on by single-celled predators. All jibberish probably, but probably also the easiest solution

A sheperd is a bot that encourges the evolution of other bots in the sim. Of course that won't mean anything if you've never experimented with the simulator yet. Its really confusing at first but I did it and I have the attention span of a...

That reminds me, do we actually have a coding tutorial anywhere? The only way to learn it from scratch seems to be meticulous DNA dissection or already knowing somebody who knows the code...
EDIT=> After rereading this thread (again), I think I finally understand the confusion. You think this is an ecosystem simulation; while something like that is by no means impossible, DB focuses more on evolution rather than coexistence. A bot will often cannibalize unless it was hand-authored, and mutations change that easily...

Theres a tutorial somwhere. I have no idea where it is or who made it. If I can't find where it is I still have it saved on my computer so I can upload it as an attachment.


EDIT:  Here it is forgot about it: Click Here



EDIT2: I tried the link and apparently it takes me to some website in spanish that tells me the file doesn't exist anymore. Anyone know where the tutorial went? You know the one with simplebot in it.

Ick, first attempts at getting coexistence to work ended in a giant Hydra eating the veggies shell and all.
EDIT=> Must be something wrong with your browser. I can access the Simplebot easily...

We aim to be but miss the mark a little bit.  Usually we have a single animal species and a single plant species.  For a true "ecosystem sim" I would like to see atleast dozens of very different species interacting and coexisting.  But if you try that in Darwinbots you usually end up with a single "victor" species of animal and vegetable.  Most alife sims fall flat in this regard, actually.

No terrain types.  Something we've been thinking about adding for newer versions but nothing's come of it yet.  Darwinpond is nice but it inevitably turns in to a monoculture (all one species).

That's italian actually.  The original author was italian.  In fact, be glad any of the program is in english   When I started tinkering with Darwinbots much of the program's source code and comments were in italian.

True, though that's actually the intent: develop something successful.  The critters are set to only be herbivores, and as this is hardwired into the game you have no chance of creating perdators or omnivores.  In later sim runs I have tried importing two or more different "species" that are already demonstrated to be successful and letting them compete; it's interesting to see what works and what doesn't.

Oh, and the other system I was thinkng of is called BugFest, and is available at necrobones.com.  It's simple but cute; and it DOES have terrain types to a limited degree, carnivores, omnivores and herbivores, as well as "abnormals" that arise from random mutations - things like bugs that never reproduce but never die, for instance.  You can set lifespans for each creature type, but you can't modify their "stats" - and yes, they are borrowed straight out of gaming, using Strength, Dex, Con, Int, Speed and Vision.  This amuses me all by itself.

I have been reviewing that tutorial often as well as the ones on the website and they seem to be quite useful, although when I'm trying to script a tie-bot the "functions" (not sure what to call them) don't work for me. (more specifically feeding through the ties)

and un-related to tie-bot I can't get the function for doing something every # of cycles doesn't work for me.

If you let the simulator run long enough mutations will be created that allow a species to cannibalize itself from them being too different.

additionally you can script your own species and not include ways for it to avoid eating it's own kind and even other species.

Tie-feeding can be done in two methods:

1.) Sharing
99 .sharenrg store will distribute the energy so that this cell gets 99% of it.

2.) Feeding
-1 .tieloc store
-1000 .tieval store

I'm not sure if this works anymore, but the idea is to 'override' the cell's -1 memory (for feeding, much like the -1 shot is a special case of positive-number shots), then the negative number forces the cell to 'eat' negative energy, thus giving the parasite 1000 nrg. I think that's the idea anyway, there's a whole bunch of variables that don't work like you think/hope they do.


As far as interesting behaviour goes, Spiral from the interesting behaviour part of the bestiary and Seasnake/Tribolis from the starting gate (somewhere   ) are probably one of the better ones. The first shows some swarm behaviour, the other two are worms.
