Conditional Pass-through, Filters about loopy

[cathalgarvey]

Kinda have a neural system going here now: accepts four inputs before triggering, then feeds back to reset. :)

Come to think of it, combined with feedback loops, both of the above might be possible to model with just one behaviour: an option to have nodes consume arrows until either full or empty, and then "overflow" in either case.

So, an overflow-enabled node that receives enough negative input would start permitting negative arrows when it's empty. Or, if it receives enough positive arrows, it would start overflowing and allow positives to pass-through. Combined with a simple feedback loop it could then act like a threshold or "emit once, then reset" node. If allowed to just overflow in one direction, it would act a bit like a filter.

I like this idea! In general, I just like the idea of making something "technically Turing-complete".

Would it still work if it was the relationships that had the asymmetric logic? For example, an arms race. US getting more nukes means USSR will get more nukes, and vice versa. Positive feedback loop. But the converse is NOT true. US reducing their nukes will not (by itself) lead to the USSR reducing their nukes, nor vice versa. So, if arrows/relationships could specify that they'd only take positive or only negative arrows –– would that be sufficient to model a gene-reg network?

@ncase I actualy think so. But not in the way he describes - it could still benefit the user in many things, it's just getting to the functionally that @cathalgarvey describes using this system would take LOTS of nodes, which because of no zomming/more space than canvas size is not possible.

Filter edge -> done in #20
overflow-enabled node -> done in #20
you can try it here : https://1000i100.github.io/loopy/v1.1/ and import your system (not breaking any compatibility)

Really cool to hear, thanks! :)

I'm happy to please you ! :)

I've breaked it with my work since the last month, (and save to link is actually broken in my version, but export to json is usable)... But, there is many new features and you can play with it and talk me about them !
