Just the way you asked non-seated turtles by ask ... with [Seated? = 0]
you can ask others by ask ... with [Seated? = 1]
However, I will suspect that they will go in a loop, because they are close to the bench ans bench is empty, so as soon as they stand up they will sit on the same spot again. Maybe you can have a memory []
which stores last few moves and if there is a seated position, say in last 10 items it will choose not to sit. I am not sure what are your requirements, this is just an example.
ask adults with [seated? = 1]
[
; Stand up set seated? = 0
; go around
]
ask kids with [seated? = 1]
[
; Stand up set seated? = 0
; go around
]
ask oldies with [seated? = 1]
[
; Stand up set seated? = 0
; go around
]
Update:
I have changed your code, its not much different from your code, but it has memory function to make sure turtles move around after leaving a bench and are not going to sit on same bench again and to some degree avoid walls (you need to improve the avoiding since step size is different for each agent):
