I have the code:
if [pcolor] of patch-here = grey and [pcolor] n-of 2 neighbors4 = grey [set X X + 1 set agentset-number = N]
This seemed to produce no error before hand, I am curious as to what is incorrect within this snippet of code and how it can be corrected.
Best How To :
The problem in your code is this expression (and you must have changed it, because it doesn't compile):
[pcolor] n-of 2 neighbors4 = grey
n-of 2 neighbors4 returns an agentset consisting of two randomly chosen patches of the four neighbors. In order to get a list of its colors, you need to use
of, so change it to:
[pcolor] of n-of 2 neighbors4 = grey
However, [pcolor] of that agentset returns a list of colors; one for each of the two randomly chosen neighbors. So here are you comparing a list of colors with a color (which is actually just a number). That will always return
You will probably want something like:
count neighbors4 with [pcolor = grey] = 2
Edited: mystery solved.
