Perhaps something like this?
to setup
cro 20
ask turtles [
forward 0.1
right who ;; who refers the the turtle's ID # (0, 1, 2, ...)
]
end
Alternatively, you can give each turtle a property (turtles-own variable), and give it a random value, so each turtle behaves differently. Something like this:
turtles-own [ turning-angle ]
to setup
cro 20 [
set turning-angle random 30
]
end
to go
ask turtles [
forward 0.1
right turning-angle
]
end
