Question

我正试图让它变成“免疫= 0”和“生病= 0”的海龟在与“生病= 1”的海龟发生碰撞时有机会生病。

ask turtles with [immune = 0 and sick = 0]
  [if any? turtles-on patch-ahead 1 with [sick = 1] 
    [if (random 100) < infection-rate
      [set sick 1]
    ]
   ]

但是，给出的错误是“WITH期望此输入是一个代理集，但是得到一个数字”。有没有办法做到这一点？

你正在做的很好，NetLogo只是感到困惑。此代码通过了语法检查程序 - 我在有问题的行中添加了一些括号。

globals [infection-rate]
turtles-own [immune sick]

to testme
  ask turtles with [immune = 0 and sick = 0]
  [if any? (turtles-on patch-ahead 1) with [sick = 1] 
    [if (random 100) < infection-rate
      [set sick 1]
    ]
   ]
end
