This is cool! I think it would be interesting to expand the language of the world. Right now the interaction with the bell or door is limited (basically binary). Even with binary it would be cool to say ring the bell three times or play shave and a haircut and then a mechanical device that could generate that frequency would be created (for ex a simplistic one would be to skip every other ring for ringing the bell). I guess that would require the world/the objects to account for interactions over some recording period.

Thanks! Great idea, I hadn’t realized the interaction is binary. It would be cool to allow for "continuous" inputs too. The world would have to account for interactions over a recording period right.

Behind the scenes, I’ve tried to make the audio production realistic, so there’s some acoustic modeling going on (eg echoes, attenuation of sound, etc). But yes you could imagine having the input forces be continuous and having the mechanism trying to figure out how to reproduce the sound exactly.

I love this idea of declarative modeling of the world because it seems to me to be the way that we as humans do it. I think the hard part about declarative is understanding intent beyond simple interactions. The current limited framing limits the expression one is capable of in the world but of course these are all tradeoffs.

Understanding intent is really hard indeed. What’s helpful about constraining it to you showing the effect is if you are able to do it, there exists at least one possible mechanism.
