Artificial Life gadget using Python

If Cell has enough eneregy
get Cell colour
Spawn new cell
set new cell colour to parent cell colour +random[/code:2g5y6fog]

The script i made so far goes like that:
[code:2g5y6fog]import random
d=Cell.Value('color')
r=System.GetRed(d)
b=System.GetBlue(d)
g=System.GetGreen(d)
Cell.SpawnObject('Cell',1)
a=SOL.Cell
a.Filter=System.rgb(r+random.randint(-10,10),g+random.randint(-10,10),b+random.randint(-10,-10))
a.SetXY(random.randint(0,10),random.randint(0,10))
[/code:2g5y6fog]
but when it is executed it generates error :
[code:2g5y6fog]File 'string' line 1061(??)
def swap values (self,p0,p1,p2,p3)
syntax error invalid syntax
[/code:2g5y6fog]
I dont understand why it showing me that because  I didnt typed that nowhere.
What i'm doing wrong ?

a.Filter = ...[/code:bn3vdkc7]
by trials and error (and I read about it on the forum) you should use .SetXXXXX to set any value
[code:bn3vdkc7]a.SetFilter(...)[/code:bn3vdkc7]

Trying to of any help I created a simple cap that creates a 20x20 grid of TiledBackground and then modify the Filter of each one by a random value.
That's my code:

-> Start of layout -> script:
[code:bn3vdkc7]
for x in range(20):
	for y in range(20):
		System.Create("Cell", 1, x*25, y*25)
[/code:bn3vdkc7]

-> Always -> script:
[code:bn3vdkc7]
from random import randint

def cb(x):
	if x < 0:
		return 0;
	if x > 255:
		x = 255
	return x

for i in range(Cell.Count):
	cell = Cell[i]
	color = cell.Filter
	r = cb(System.getred(color) + randint(-5,5))
	g = cb(System.getgreen(color) + randint(-5,5))
	b = cb(System.getblue(color) + randint(-5,5))
	cell.SetFilter(System.rgb(r,g,b))
[/code:bn3vdkc7]

May be this will help you.
