:) I'm making something nobody wants right now and it's going great. It's giving my life the most purpose it's had in a few years. It's a financial disaster, of course, but trading money for personal fulfillment is a sweet deal IMO.

(and a shameless plug...)

https://ant.care/ if you want to derp around with a digital ant colony for a bit. The nest devolves into a mess after a couple of days tops right now.

If you think you've got ideas on how to improve the tunnel/chamber/nest expansion logic, or if you're better at implementing sand fall physics in Rust/ECS than me, I'd love to chat!

I didn't quite understand the ants behaviours, like moving sand around, but thoroughly enjoyed this simulation. Cute.

[SeanAnderson]

I'm glad you found it cute and enjoyable! I completely agree their behaviors need a lot more love, but I am ready to give it! :)

The actions of the workers are just probabilistic for now - they lack any true motivation.

The queen ant has an instinctual goal of creating a sufficiently spacious nest that is sufficiently deep underground. When she achieves that goal, she stops movement and begins giving birth to ants. Those ants then dig out the nest further.

I am trying to figure out how to make the digging more... inspired? Something like "If ants keep finding themselves surrounded by other ants underground then they need more space and should consider digging" or "If an ant fails to find a place to put food then it should consider digging"

I think that both of these things have a prerequisite of having tunnels/chambers built more effectively, though. I've played around with some rules like "Don't dig dirt if there is air on the opposite side of the dirt" in an attempt to prevent the nest from turning into a giant pit, but this doesn't result in tunnels and chambers, just delays the inevitable pit-like behavior.

In the future, there will be an "outer world" which has the more classic "ant follow pheromone trails to find food" mechanism. You'll see ants disappear out the sides of this view and see them explore from a top-down view. The outer world will get covered in fog each night and push all the ants back to their nest for sleeping and eating. Just trying to get to the point where they sensibly store food before expanding into that.

.. and if that was more info than you were looking for, sorry :D Just excited to talk about my thing.

If you have never looked at Dwarf Fortress, I recommend you take a look. https://www.bay12games.com/dwarves/

Note: Dwarf Fortress is enormous, like trying to look at those 7000 item long Factorium expansions while not going crazy, and I suggest it not as discouragement. Simply ideas about those types of goal based behaviors.

Much of the behavior is based around creating caverns of various types, and then sending workers to find resources, gather resources, process resources, and then use those for even greater complexity tasks.

[neontomo]

I wish I could help you figure it out, but I don't know much about these types of algorithms. Possibly, they already exist and you can plug them in. I know there's a lot of work done on maze-generation in games, maybe you can think of the tunnels as a maze, and pre-generate a path they will take, and update that model as other ants interact with it. Anyway I love the enthusiasm and wish you luck!

[SeanAnderson]

Thank you! And yes, I agree. I was looking at uh https://github.com/mxgmn/WaveFunctionCollapse and wondering if that were applicable here :)

Have a good day!

This is extremely cute and I'm glad you shared this :)

[SeanAnderson]

Glad you liked it! Thanks for taking a look.

My friend studies ants. I will share this with him

This is interesting!

This is awesome!
