[starlogo-users] Need help

[Zara Phang]

Hello everyone!

I'm trying to do some cellular automata on StarLogo and was wondering if 
someone could help me with something I think should be quite simple but I 
haven't managed to do yet!

I've basically got agents lined up on an x axis randomly placed by y, so 
maybe like this:

xxx x x     x xxx    x xxx

and I want to figure out whether each agent has another agent in front of 
them.  I'm currently using the 'smell' feature under 'Other Agents' with a 
radius of 1, which tells me that whether there is an agent either side of 
it, so I think I am halfway there!  I have tried the 'smell with' with a 
radius of 1 and a condition of (xcor of who > xcor) but this doesn't seem 
to work.

Does anybody have any ideas what is going wrong and how I can fix this?

Many thanks,
Zara
