I found a 46C spaceship, but it can't be made into a a 50C spaceship because this design only works for speeds that are one less than primes.

EDIT: When I was posting this, I found that unless the extended RLE gives the pattern's coordinates, LifeViewer places the pattern in the upper left of the torus but Golly places it in the middle. This isn't a problem for tori, but the same thing also happens on a bounded grid, which causes some patterns to run differently. Fortunately this can be avoided by explicitly specifying the coordinates.

I especially like the dynamics of the dying cells. Turn up the states to make it even cooler, but more stable.
My favorite #states are C6,C7,C8 (Hypnotic!), and C10 (Although not explosive)

It would mean modifying the underlying ghashbase code to support extended neighborhoods. I can't see that happening any time soon (I certainly have no plans to attempt it).

It's certainly possible (I almost implemented it) but I'm not sure it's all that desirable. It potentially means supporting rule strings with thousands of characters (Golly's current limit is 500). I might raise it with the other Golly devs and see what they think.

Maybe it could be like S1,3-7,9,15,17-19, where dashes indicate consecutive conditions.

About half of these guns are strangely intermittent multi-guns, i.e., they produce more than one output object in each period.

I'm noticing on my old laptop that these patterns run significantly slower when the grid is being drawn -- i.e., moving from scale 1:4 to scale 1:2 actually slows down the simulation noticeably, where it seems as if it ought to speed things up if anything because fewer cells have to be drawn. And then things run much slower as soon as some of the boundary is visible. Do other people see the same kind of behavior?

Did you mean moving from 1:2 to 1:4 (zooming in)?

They both use the same render path but 1:4 additionally draws the grid lines.

Yup, sorry, that's what I meant. It made sense in my head when I wrote it... Is there any way to have the grid lines be an invariant background layer, somehow, and draw the changing cells on top of that background? It seems a little silly to have to do all that grid-making work every time the universe is redrawn.

Does your laptop render faster with the grid-lines off at 1:4 (hotkey "L")?

Yes, that makes a huge difference -- roughly a factor of three improvement in simulation speed (60+ ticks per second instead of 20 ticks per second, running in QuickLife at step 10^0).

There really isn't going to be a way, short of writing a new algo for Golly for that specific purpose... and that particular mix of rule types just doesn't seem to make much sense.

You might as well just write a script that keeps track of where the LTL ships are, simulates them in a separate layer, and cuts them out before each evolution step and pastes the next generation back in.

To find my rule, I simply modified the Life rule to have a range 2 von Neumann neighbourhood, then upped the states until it wasn't explosive.

It doesn't work most of the time.

A rule.
I call "fire whirl"

I just found an interesting rule by playing around with the Life default. It has lightspeed rings that act as 'space-nonfillers':

Code: Select all

``````x = 3, y = 4, rule = R2,C14,M0,S2..3,B4..4,NM:T400,400
A\$A.A\$A\$.A!
``````
It also has a natural 10c/20 diagonal, a 9c/12 diagonal, a 9c/6 orthogonal, and a 36c/24 orthogonal:

Code: Select all

``````x = 123, y = 33, rule = R2,C14,M0,S2..3,B4..4,NM:T400,400

There's this unnatural 9c/12 diagonal too:
