It doesn't work for me with python 2.5.4...which version of python should I use with the ssship script?

Posted: **March 8th, 2011, 9:35 pm**

When I use ssstream.py, it seems that python 2.7 works when using the script, but it's probably not the only version that can work for this script

That doesn't tell me much -- what error message do you get? I've tested the script with 2.3 and 2.7 without any problems. I can't see anything in the script that would prevent it working with your python.

It is telling me "NameError: global name 'g' is not defined"

Useful clue. There was a line calling "g.warn" rather than "golly.warn" so I've fixed that in the code below. (I guess it didn't cause any problems for me because I must have already run another script that did an "import golly as g".)

Thanks, it's working now.

Can somebody make a script that, like the move-object.py script, move an object on a torus because when I use it on a torus where an object is on an edge, it only grabs that portion of the object.

Posted: **March 21st, 2011, 10:12 am**

Well, if the pattern is a small one without large gaps, you could always paste the left part by hand, and then paste the right part to the left of the left part in the corresponding position. (Just make sure that it works correctly. This method also works for objects spanning top and bottom, as well as objects straddling the corner, but that case takes longer.)

Or, if the torus is a small one, just copy the whole thing and then paste it several times next to another copy. (This would be in an infinite planar universe, a.k.a. the standard one.)

Can someone update and/or fix the LWSS & MWSS gun maker script for me? I would be very thankful.

Posted: **October 23rd, 2011, 8:45 pm**

I've added three new scripts to the Golly Scripts Database:

benchmark.py -- Does a simple timing test using the current algorithm + rule + pattern.

hexrot.py -- Rotates a hexagonal neighborhood pattern by 60 degrees clockwise. Here's a glider in a hexagonal rule for testing the script:

Code: Select all

x = 7, y = 6, rule = B245/S3H
obo$4bo$2bo$bo2bobo$3bo$5bo!

save-bmp.py -- Saves the current selection/pattern as a .bmp file. Unlike save-image.py this script does not require PIL (Python Imaging Library).

Could someone change the script so it works for selections?

Posted: **November 12th, 2011, 4:49 pm**

Something I think would be useful is a script to count how many of each color cell there is, rather than just the total number of live cells.

I have no experience writing scripts, but I have figured out a way to turn Von Neumann neighbourhood ruletables into Moore neighbourhood ruletables. I may need this script for a project I am working on. Namely "Arrows WW".

It would be nice if it could also change 1-D and hexagonal neighbourhoods

I wrote this script to convert LifeHistory to Life. Those pesky state 2 cells almost always get in the way!

Code: Select all

# Change the selected area from N states to Life states:
# s -> 1+2s (if in the top-left of the partition)
# s -> 2+2s (if not)

from glife import rect
import golly as g

r = rect( g.getselrect() )
if r.empty: g.exit("There is no selection.")

for row in xrange(r.top, r.top + r.height):
   for col in xrange(r.left, r.left + r.width):
         g.setcell(col, row, g.getcell(col,row)%2)

When I run it, it gives me this:

Traceback (most recent call last):
File "<string>", line 1, in <module>
File "C:\Users\a\Desktop\golly-2.2-win\Patterns\_Scripts\Python\lifehistory.py", line 5, in <module>
from glife import rect
ImportError: No module named glife
I moved my Scripts into my Patterns folder (along with the glife folder).

A small script that counts the objects (object is connected pattern, like glider, block etc.). Made mainly for still life object count.

Code: Select all

import golly as g
from copy import copy

def FindActive():

	rect = g.getrect()
	
	for i in xrange(rect[0], rect[0] + rect[2] + 1): 
		if g.getcell(i, rect[1]) > 0:
			return (i, rect[1])
			
def FindConnected(listXY):
	result = copy(listXY)
	
	for xy in listXY:
		x = xy[0]
		y = xy[1]
		
		for i in xrange(-1, 2): 
			for j in xrange(-1, 2): 
				if g.getcell(x + i, y + j) > 0 and len([i for t in listXY if (t[0] == x + i and t[1] == y + j)]) == 0:
					result.append((x + i, y + j))
			
	return result
	
def RemoveList(listXY):

	for xy in listXY:
		x = xy[0]
		y = xy[1]
		g.setcell(x, y, 0)

total = 0 
g.run(1)

while int(g.getpop()) > 0: 
	xy = [FindActive()]
	
	while True: 
		newXY = FindConnected(xy)
		
		#g.getstring(str(xy) + " : " + str(newXY) )
		
		if len(newXY) == len(xy):
			break
			
		xy = newXY
	
	RemoveList(xy)
	
	g.show(str(total))
	g.update()
	total += 1

g.show("The total Objects cound is: " + str(total))
g.reset()

While on it, here is a much faster LifeHistory->Life converter, that creates a new document and set it to Life rule.

Code: Select all

# Change the LifeHistory N states to Life states and set the rule to Life
# s -> 1+2s (if in the top-left of the partition)
# s -> 2+2s (if not)

import golly as g

cells = g.getcells(g.getrect())

g.new("")
g.setrule("B3/S23")

i = 0 

while i + 2 < len(cells):
	
	x = cells[i]
	y = cells[i + 1]
	val = cells[i + 2]
	
	if val % 2 == 1: 
		g.setcell(x, y, 1)
		
	i+=3

And here is one that does it in LifeHistory, so the undo operation is available.

Code: Select all

# Change the LifeHistory N states to Life states and stay in LifeHistory
# s -> 1+2s (if in the top-left of the partition)
# s -> 2+2s (if not)

import golly as g

cells = g.getcells(g.getrect())

g.select(g.getrect())
g.clear(0)

i = 0 

while i + 2 < len(cells):
	
	x = cells[i]
	y = cells[i + 1]
	val = cells[i + 2]
	
	if val % 2 == 1: 
		g.setcell(x, y, 1)
		
	i+=3

g.select([])

Here is a smart paste script. It creates a new document, and sets the rule to the rule in clipboard and places the pattern in (x,y) written in rle. Very useful for paste in threads with multiple CA rules.

Code: Select all

#Smart past -> sets the rule of golly to the one in clipboard and paste it in the location of the x,y in the rle format 
import golly as g 

g.new("")
s = g.getclipstr()

s = s.split()

while len(s) > 0 and not s[0].startswith("x"):
	s.pop(0)

if len(s) < 10:
	g.exit("wrong length" + ":" + str(len(s))+ ":" + str((s)))

if s[0] == 'x' and s[1] == "=": 
	x = int(s[2].split(",")[0])
else: 
	g.exit("no pattern selected there is no x")
	
if s[3] == 'y' and s[4] == "=": 
	y = int(s[5].split(",")[0])
else: 
	g.exit("no pattern selected there is no y")

if s[6] == 'rule' and s[7] == "=": 
	rule = s[8]
	
	pat = ""
	for i in xrange(9,len(s)):
		pat += s[i]
else: 
	g.exit("no pattern selected there is no rule or pattern")

cells = g.parse(pat)
g.setrule(rule)
g.putcells(cells, x, y)
g.fit()

For pattern engineers in hexagonal rules, hexagonal rotation can take several minutes. To rectify this problem, here is a hyperfast version of hexrot.py, working with cell lists instead of sets of rings.

Code: Select all

# Rotate selection in hexagonal neighborhood by 60 degrees,
#   with rotated pattern placed in new layer.  

import golly as g  
if g.empty(): g.exit("There is no pattern.")
rect = g.getselrect()  
if len(rect) == 0: g.exit("There is no selection.")
x = rect[0]  
y = rect[1]   
clL=g.getcells(rect)
lngth = len(clL)
nl = g.addlayer()
indx=0
incr=2
if lngth % 2 == 1: incr = 3
st = 1
while indx < lngth:
  i=clL[indx]
  j=clL[indx+1]
  if incr == 3: st = clL[indx+2]
  g.setcell(x+j,y-i+j,st)  # (x-j,y+i+j) before inverting y values
  indx = indx + incr

Here is the updated version (the previous version of the script put the rotated pattern outside the viewpoint) of the fast hexagonal rotation script.

Code: Select all

import golly as g  
if g.empty(): g.exit("There is no pattern.")


rect = g.getselrect()  
if len(rect) == 0: g.exit("There is no selection.")

#x = rect[0]  y = rect[1]   
wd = rect[2]   
ht = rect[3]
clL=g.getcells(rect)
lngth = len(clL)
if lngth == 0: g.exit("You selected nothing.")
nl = g.addlayer()

indx=0
if lngth % 2 == 1: 
  lngth = lngth - 1
  while indx < lngth:
    i=clL[indx]
    j=clL[indx+1]
    #g.setcell(i,j,clL[indx+2])
    g.setcell(j,-i+j,clL[indx+2])  # (-j,i+j) before inverting y value
    indx = indx + 3
else:
  while indx < lngth:
    i=clL[indx]
    j=clL[indx+1]
    g.setcell(j,-i+j,1)  # (-j,i+j) before inverting y value
    indx = indx + 2

g.setpos(`j`, `-i+j`)

Is there an easy way to rotate clockwise/counterclockwise a cell array?

Posted: **June 8th, 2014, 8:39 pm**

codeholic wrote:Is there an easy way to rotate clockwise/counterclockwise a cell array?

In a regular square neighborhood rule, not hexagonal?

putcells(), transform(), and parse() all have optional transform parameters. Sample usage -- draw something in a new universe between (0,0) and (99,99) before you run it:

Code: Select all

import golly as g
all=g.getcells(g.getrect())
g.putcells(all,100,0,0,-1,1,0) # clockwise turn
g.putcells(all,0,100,0,1,-1,0)  # counterclockwise
g.putcells(all,100,100,-1,0,0,-1) # 180 degrees
g.fit()

But maybe golly.transform() is a better answer, if you want to put a cell array in and get a cell array out. (?)
