question - How do I get the pxcor of the most right patch

[רם תמיר‎]

Hi

I have patches in different colors. I'm trying to get the pxcor of a green patch that is furthest to the right.  How can I do that? I'm adding an image for clarity

Try the following, it should do the trick. You look at all green patches, take the one with the highest pxcor, and then return that pxcor

[pxcor] of max-one-of(patches with [color = green]) [pxcor]

Small typo in the with clause that should be pcolor instead of color:

   [pxcor] of max-one-of patches with [pcolor = green] [pxcor]

Oh right. Somehow I keep making that same mistake, specifically for patches. Good thing Netlogo always points it out to me.

Thank you both for the replies. I've tried your solution, but it gives me an error that I can't figure out. I'm trying to assign it to a variable like this:
actual-width  =  [pxcor] of max-one-of patches with [pcolor = green + 1] [pxcor] but it gives me an Expect command error. I've looked up the syntax and it looks fine, seems like all the brackets that should be there are there. What am I missing?

[Wannes...@hotmail.be]

The syntax error is not in choosing the patch but rather in how you are assigning it to a variable. In Netlogo you assign a value to a variable by using: `set actual-width ... `
`=` is only used for logical expressions.

That's right and so obvious. Using = is so ingrained in me that I don't even see it and keep making that mistake. Thanks.
