I have three different turtles: red, white, and green. I am trying to get these turtles to couple up (like people in relationships) and then uncouple. While a red turtle is coupled with a green or white turtle I want the patch color to sometimes randomly change colors, but for some reason the patch color color progression is not working.
to go
ask turtles
[ if coupled? = true
[ set couple-length couple-length + 1 ] ]
ask turtles
[ if coupled? = false
[ move ] ]
ask turtles
[ if coupled? = false and shape = "person righty" and (random-float 10.0 < coupling-tendency)
[ couple ]
let potential-intervener one-of (turtles-on neighbors) with [ green-dotter? = true]
if (coupled? = true and potential-intervener != nobody and "person righty" = true)
[ifelse (random-float 10.0 < resting-tendency)
[;;decides to stay
ask potential-intervener [move-to patch-here] ;; this is possibly what is causing the lack of intervention?
; does not intervene, start the color progression
ifelse (random-float 10.0 < intervening-tendency)
[;; intervenes
uncouple
]
[set couple-length couple-length + 1 ;; increments the couple length by 1
if (couple-length = 2)
[
ask patch-here [set pcolor yellow]
ask patch-at -1 0 [set pcolor yellow] ]
if (couple-length = 4)
[
ask patch-here [set pcolor orange]
ask (patch-at -1 0) [set pcolor orange] ]
if (couple-length = 6)
[
ask patch-here [set pcolor red]
ask (patch-at -1 0) [set pcolor red] ] ]
]
[
;;decides to move
ask potential-intervener [move]

For one thing, your line if (coupled? = true and potential-intervener != nobody and "person righty" = true) is inside a command block that is only reached through if coupled? = false and shape = "person righty" and (random-float 10.0 < coupling-tendency). That is, it doesn't get reached because coupled? would need to be both true and false. Better formatting would make this immediately clear. I have reformatted the top part of your code so you can see this:
to go
ask turtles
[ ifelse coupled?
[ set couple-length couple-length + 1 ] ]
[ move
if shape = "person righty" and (random-float 10.0 < coupling-tendency)
[ couple ]
let potential-intervener one-of (turtles-on neighbors) with [ green-dotter?]
if (coupled? and potential-intervener != nobody and "person righty")
[ ifelse (random-float 10.0 < resting-tendency)
[;;decides to stay
ask potential-intervener [move-to patch-here]
A couple of other notes. You don't need to say if coupled? = true, it is sufficient to say if coupled?. Since you have the same colouring code three times, it would be better to have it only once as a separate procedure and call it from the three locations, so it is much easier to change.

I am trying to simulate the following situation. Young and old agents.
The old have few social contacts, slower and at the same time have a greater chance of dying.
Young people have more contacts .
Which group should be vaccinated first ?
I created two groups, assigned an infection algorithm, and assigned a social distance. But at the same time I do not see the relationship, the agents behave identically, where is the error?
I'm a beginner and don't want to complicate the model. please don't answer difficult I'm just learning

I am trying to infect some agents from others, while I am not interested in the incubation period and trying to link age (less movement and less contact) with morbidity.
But I see that the result is not presentable, there is no dependence on age and morbidity.
The transmission-old is your problem. You copypasted from transmission-young but forgot to replace ask young with ask old
to transmission-old
ask old with [color = orange]
[let susceptible-person one-of old in-radius 3 with [color = 4]

I've been fighting for a week, I changed the concept, I think it's easier. How to describe the last block. If there is one infectious neighbor, he will transmit his infection with faithfulness....

I want to write an evacuation with leader code in net-logo but i have this error (AND expected input to be a TRUE/FALSE but got the number 0 instead.)the error came from function (follow_leader). my project is that i evacuate an environment and evacuate it with the nearest leader from the crowd . the code is not perfect that because iam knew to netlogo .

end
In the future, please only provide relevant code. For NetLogo, that is usually the procedure that throws the error (or doesn't work correctly etc) and whichever procedure calls it.
In your case, this is the procedure you mentioned:
to follow_leader
let nearby-leaders turtles with [is-leader? and distance myself < 10]
if any? nearby-leaders[
face min-one-of nearby-leaders [distance myself]
fd 0.5]
end
So the and that is throwing the error must be [is-leader? and distance myself < 10] (also, please state which line if you know it). My guess would be that you haven't initialised the variable is-leader? so it is 0 (the default value) instead of either true or false.
If this is the problem, wherever you creates turtles, initialise with set is-leader? false
I'm modeling a critical situation that's happening in my city (Viña del Mar, Chile), where the "metro" (subway)can have serious problems if a tsunami occurs because the evacuation exits are not well prepared nor well managed.
This example is a simple model of the real one, but i was having really big problems trying to make the turtles move from the subway (blue patches), using the door (lime patch) and then jumping into the railways (gray patches). When i finally made them do those actions i found 2 problems: (1) the ticks aren't working the way i need them to work. I need it to run like it was a clock, counting seconds. (2) i create 3 actions called "check-vecinos-azul/lime/gray" where they need to check if there's any turtle arround them (neighbors). If there's an empty space arround a turtle it moves to that empty spot, otherwise it stands until it finds an empty one.
I'd be so glad if anyone of you could give me a help/tip with my model.
Thank you guys,
Kind regards,
Felipe.

I'm creating a program in Netlogo which has shoppers (turtles) moving through a grocery store layout. When they step on a patch it increases in color and when it has no agent on it, it decreases in color, as this will show the paths shoppers take through a store.
My code is:
ask turtles
[ rt random 360
fd 1
set pcolor pcolor + 1 ]
ask patches with [ (pcolor > 9.9) or (pcolor < 0.1) ]
[set pcolor 0]
ask patches with [ (count turtles-here = 0) and (pcolor <= 9.9) and (pcolor > 0) ]
[ set pcolor pcolor - 0.1 ]
However, as the aisle patches are blue this is turning them back to black as well. I was wondering what code I could use so patches with pcolor = 105 will stay blue and not change to black?
Don't change the color of the patches with pcolor = 105. You'll just need to add an additional condition to anywhere you modify the patch color.
ask turtles
[ rt random 360
fd 1
if pcolor != 105[set pcolor pcolor + 1 ]
]
ask patches with [ pcolor != 105 and ((pcolor > 9.9) or (pcolor < 0.1))]
[set pcolor 0]
ask patches with [pcolor != 105 and (count turtles-here = 0) and (pcolor <= 9.9) and (pcolor > 0) ]
[ set pcolor pcolor - 0.1 ]
I want to place turtles on each of the black patches(below Figure) at a specified step size:
Therefore if step size less more turtles will be created/sprouted and more step size will result in less turtles.
Code I use right now:
ask patches with [pcolor = black][sprout-dead-turtles wall-agents [set color red]]
This gives the following result:
