I see people making rules where certain states behave differently than each other, and I don't know how they do it. Could anyone tell me how to make a rule where each state has its own rule? Or something like that
There is this:Tutorials/Creating custom rules
You can also assign variable to states like
var a={1,2}
So if states 1 and 2 make no difference in the evolution of a third state when in its neighbourhood (basically they're interchangeable) you can compact rule table lines describing evolution. There are also a bunch of other things you can do but I really don't know, you can look here:https://github.com/gollygang/ruletabler ... /TheFormat
If anything I've said is wrong, I'm sorry, I'm really not good at making rule tables.
Ok, I pretty much get it but, where in the code do we put the @COLORS string? Is it after the B/S requirements or somewhere before it?

Code: Select all

x = 0, y = 0, rule = B3/S23

I've never used colors before, just try in different places. I think it was the in the end.
Me, BokaBB, Moosey, Saka and some others are working on a language! Feel free to help us. viewtopic.php?f=12&t=4772

Has anyone investigated Generations variants where off cells can directly become refractory under certain conditions? If not, I might investigate one.
Marine has a non-centered Moore neighborhood and at least one elementary gun with a very high period (11,843).

I don't understand why its implementation needs so many states, though.
Essentially, because one state is needed for every combination of cell color and ant direction, plus 2 more for cells without ants on them, so 10 total.

Also, is there any way to specify that the rule should be isotropic but not outer-totalistic?
Marine has a non-centered Moore neighborhood and at least one elementary gun with a very high period (11,843).

Has anyone investigated Generations variants where off cells can directly become refractory under certain conditions? If not, I might investigate one.
I made a preliminary rule but cannot figure out how to run it in LifeViewer.

Is there any other way to do this? I haven't decided on a particular Generations-like rule to use, I don't want to until I'm able to see which rule has the most interesting objects (e.g. spaceships), I don't want to create potentially ten or more rules with the intention to use only one, and I don't want to modify a rule page after it has been created in case other users decide to investigate it.

I'd say just keep playing around with it in Golly until you find something you're satisfied with.

Is it possible to have a rule where (stable, at least) object (or even just spaceship) speeds are bounded above some unreachable limit, say, c/2, and for any reachable speed there exists a higher reachable speed; that is to say, any (stable) object (/just spaceship) that exists in the rule can be caught up to by a spaceship (of higher speed)?
Here is a potential solution where the ship's orthogonal speeds approach c/2, and there are no obvious c/2 ships.

You answered this question before, but I think the question asks if there is a rule where for every spaceship you can find a faster spaceship, but every spaceship travels under some limit.
Edit: You said no obvious c/2 spaceships but they very probably exist. There should be a proof of no spaceships moving at the speed limit.

It is true that there most probably is a c/2 ship, or at least that a proof of non-existence would be hard to find, but I do think this concrete example has the property of orthogonal ships always being reachable by a faster ship.

I think that that's c/4, not 2c/4.
Also, it's possible that attempts to clean up its ash would interfere with the engine.

Each glider phase-shifts the p19 by 2 generations mod 19. Therefore, using one glider per cycle gets us 59+19n, as you found. If we use 2 gliders per cycle, we get a phase shift mod 4, but due to the repeat time this only gives us 137+19n (137=2*59+19, since the "p118" is really p59. The gliders alternate between being spaced at 59 and 78 generations). Similarly, if we have 3 gliders per cycle we get periods starting at 3*59+19=196. Thus we have glider loop oscillators of each mod-19 residue starting at 59, 137, 196, 255, 314, 373, 432, 491, 550, 609, 668, 727, 786, 845, 904, 963, 1022, 1081, and 1140 (59*19+19, completing the cycle) and every period of the form 1122+n starting at 0 (59*19+1, skipping after the last gap; coincidentally, that's today's date).
