Everyone knows yellow turtles hate green ones and vice-versa. Putting them in a pond together is a recipe for a rumble:
This model customizes BAM2, the framework for interacting turtles. In this case turtles interact by fighting if their colors are different.
to interact [candidate]
;spill some blood:
ask patches in-radius vision [set
pcolor red]
; make some noise
beep
let my-blow random energy
let candidate-blow random [energy] of
candidate
dec-energy candidate-blow
ask candidate [dec-energy my-blow]
;clean up the blood
ask patches in-radius vision [set
pcolor black]
end

to-report qualified?
report color != [color] of myself
end

to-report qualified?
report [color] of self != [color] of
myself
end
Here's the code:
