Hello Mira.
If you want to restrict the cell for the agent initialisation, you can't
use this méthode
self setRandomlyLocatedAgents: n:
Try this :
100 timesRepeat:[(self newEntity: Tourist) init].
destinations := OrderedCollection new.
destination := self theCells select: [:cell| cell state = #Lands
or:[cell state = #streets]].
self theTourists do:[ :t| t moveTo: (CormasRandomlyFrom: destinations)].
Good luck
Romain
