Moosey,

Good start! Now construct period 19, 23, 34, 38 and 41 guns.

Re: Pattern viewer for forum threads

Displaying a path traveled by a moving object, a ship or oscillator, is useful. How can a user control such a path? How can it be turned on or off? How can the path's color be specified? How can the rate of fading be adjusted?

PCA support is now really good. Selector rotations seem to be working. An excellent demonstration of a new rule.

No problems (assuming PCA.lua is running). Copy the pattern to the clipboard, switch to PCA.lua and type shift-O (or select Open Clipboard from the File menu.
Thank you for this and the startup script. Works well.

Experimental support for PCA has been added in Build 425 . Please let me know if you find any issues. No issues, well done!

testitemqlstudop,

One of the families of rules supported by Square Cell is called Rule Table which supports your rule directly.

The specification of your rule is:

I still strongly object. I also object to bounties and like buttons. This forum should be entirely devoted to the discussion of cellular automata. There is already far too much pollution generated by our younger members.

Very interesting Brian. Have you been able to stabilise the growing end of that puffer / gun pattern - or have you found a more regular gun? No to both questions, I will probably explore PCA_12 today. I decided to take a foray into the world of NewCA.lua ... A very good start. The pattern editing f...

PCA_12 is a reversible PCA rule that supports guns. The rule: /* Put your state count, neighbor count, and function here */ final static int numStates = 16; final static int numNeighbors = 4; private int rule[] = {0,4,2,3,14,6,11,5,8,7,9,13,10,12,1,15}; /* order for nine neighbors is nw, ne, sw, se,...

Re: Partitioned Cellular Automata

It is easy to generate non symmetric PCA rules. Rule PCA_11 is such a rule: /* Put your state count, neighbor count, and function here */ final static int numStates = 16; final static int numNeighbors = 4; private int rule[] = {0,4,8,3,1,10,6,11,2,9,5,11,13,12,14,15}; /* order for nine neighbors is ...
