Answer 1

完成此操作的簡單方法是使用某種計數器。這裏是一個完整的例子：

turtles-own [ counter ] 

to setup 
    clear-all 
    create-turtles 100 [ 
    set counter 0 
    setxy random-xcor random-ycor 
    ] 
    ask n-of 25 turtles [ set color red ] 
    ask n-of 100 patches [ set pcolor red ] 
    reset-ticks 
end 

to go 
    ask turtles [ 
    ifelse counter = 0 [ 
     look-for-food 
     if color = red and pcolor = red [ 
     set counter 10 
     ] 
    ] [ 
     set counter counter - 1 
     set label counter ; just to show what's going on 
    ] 
    ] 
    tick 
end 

to look-for-food 
    ; your own look-for-food procedure is presumably different 
    right random 20 
    left random 20 
    forward 1 
end
