creating machines in GOL

Postby kubuni » March 2nd, 2019, 5:24 am

I still consider myself a newbie with GOL patterns and object creations. I came across this video : https://www.youtube.com/watch?v=8unMqSp0bFY I was wondering if there was a tutorial on how patterns interact with one another. I would love to make a basic counter or something like this : https://www.youtube.com/watch?v=3NDAZ5g4EuU

I would like to start small and try to do more complex things like these.

There's actually a Life textbook coming along, with step-by-step explanations and end-of-chapter exercises and everything, for building complex mechanisms in Conway's Life. Hopefully it will be done in time for the Martin Gardner Life article's quinquagenary (October 2020) -- but unfortunately it's not quite ready for public release yet!

There actually isn't all that much on pattern-building on the LifeWiki Tutorials page yet. Maybe you could write a beginner's tutorial once you figure out what you want to know -- but by then you won't be a beginner any more, so that doesn't help you now.

People do write walkthroughs for creating various large patterns now and then, but those are usually talking to people who know all the strange jargon already, so might be jumping in too much at the deep end. On the other hand, if you just start looking up the terms in the LifeWiki, you'll figure it all out eventually.

The usual thing to do is to download Golly, find the patterns you're most interested in in the pattern collection, check the comments for the pattern ("i" keyboard shortcut), and then start experimenting until you understand how the pieces work. For constructions like Coban's computer, maybe start with Patterns/Life/Signal-Circuitry/p30racetrack.rle and p46-racetrack.rle.

There is?! Who's writing it? Does it have a publisher and intended audience? This sounds really cool, and I am surprised it did not come up in the "Broader Audience for CA" discussion. I would like to know more about this.
