Mini-eco
shvarz:
I want to make a small ecosystem with veggy, herbivore and a carnivore. Someone tried that before with ursus bots, but it was not a very robust ecosystems, because the guy who made it could not make very efficient bots. I figured I'll take some good exisitng bots and make "herbi" hunt only "veggies" and "carni" to hunt only "herbi".
I'll disable mutations, so this is specifically about creating an ecosystem, not dong any evolution.
The plan is to have a fairly small system (size 3 field) with about 100-300 veggies, 50-100 herbis and 20-50 carnis. To make things easier to follow I want to have herbi that feeds only through ties. And carni that feeds only through shots.
So, could someone recommend good bots that use only one but not the other? I wanted to look up in database, but it seems like it went down at some point.

I honestly don't think I know of any bots that have ever been made that are exclussivly carnie(there was a SG herbi once). The problem with carnis is that initially there is no real prey to eat. I just barely got a cycle started with Mutbot and mainly only through it's phenotype nature.
It wouldn't be too hard to design one though, the bot just has to eat anything with a refeye greater than zero and not equal to it's own. The herbi would be similar just eat anything with a zero refeye.
You'll need to worry about over hunting by the carnies. Perhaps a faster repro rate would make up for this along with their higher nrg feeding levels.
Probably want to add nrg firing corpses to the mix, this allows a bot to "feed" via proximity(no ties or shots); allowing another rung in the ecosystem ladder.

Yes, I imagine it would be fairly easy to make them hunt a certain species exclusively by using ref commands. I'm mostly interested in a bot that feeds only through ties. There are plenty of shot-only bots, but I don't know of any tie-only.
Reproduction and energy flow is what I'm planning to tweak to make the system stable. Carnies would have to be pretty tough creautures to be able to survive fairly long periods of starvation. But then they don't have to go searching for food, as prey will run by them now and then, so they can sit tight and conserve energy.

Sharer, Tie feeder, or both?
Sharers would be the easiest from an eco point of view. The carnies could defend against accidental "attacks" easily and the herbi itself could deltie before feeding on a non veggie. Sharers are also generally weaker than shot bots so the relationships should fall into place easier.
I'll see about making some bots. I haven't really tried making anything truly complex recently; mainly just deliberatly simplistic evobots. :)
shvarz:
I thought a bit about this and now I think that with small modifications I can make a sim stable enough even for evolution. The three species will be:
1. Alga minimalis making a lot of shell, so that it is resistant to shots.
2. Tie-feeding herbivore, unable to shoot. Runs around eating veggies and reproducing to fairly high numbers.
3. Shot-feeding carnivore, sits in one place waiting for herbivore to run by. Can brake ties so that herbi can't attack it. Very good and efficient bot, reproduces rarely and can survive long periods of starvation.
These three species are in such a relationship that it is very difficult for them to move outside of their ecological niche. So I think evo-sims are possible.
Endy, if you want to make bots specifically designed for this, go ahead. I was thinking about modifying some existing ones, but I need advice on which are the good bots and may need some help in modding them to my needs.
Looks like "hunter 2.3" is the leading bot in F2, but I don't think it uses ties, I think it mostly uses shots. So that one (if tie-usage is completely removed) can be the predator.
I can make shell-making alga on my own.
But I need some bot-makers to recommend (or make) a good tie-feeding bot. Anyone? Don't be shy :)
