Re: [netlogo-users] How to check if 2 different breeds of turtles are on the same patch
Efrat Dener
--The final part of my design involves me recording down anytime a car breed drives into or in netlogo terms, is on the same patch or X and Y coordinate as the people breed as they navigate across the edge of the screen. Had this been java I could've done something like
if Car.xPostion == Person.xPostion
(Do something...)
But unfortunately I do not know how to do the same in NetLogo, all I've been able to do so far is just ask the two breeds by giving every turtle a boolean variable called movable and setting them to true and the rest to false, is there anyway I can check the two coordinates of two different turtles on Netlogo? This is all I 've been able to do so far.

Didn't really understand that, please explain

You can use turtle-set to make a set from two different breeds and perform actions on them

Hi,
I have attached a simple model in which collision info is output to the command center.
You can write the output to a file. See
https://ccl.northwestern.edu/netlogo/docs/dictionary.html#file-type
and the associated links.
The most relevant method is record-collision (see below) in which the people check for cars on their location using cars-here.
We need to be careful to account for the case when there are no cars here, so any? Is used.
See <breeds>-here
https://ccl.northwestern.edu/netlogo/docs/dictionary.html#turtles-here
and
any?
https://ccl.northwestern.edu/netlogo/docs/dictionary.html#any
to record-collision
; If a person has a car on its location, that is a collision.
; Note: if neither turtle moves, another collision at the same point will
; be recorded
ask people [
if any? cars-here [
type "Ouch! Collsion at "
type xcor
type " "
print ycor
]
]
End
Aaron
