使用Netlogo过程添加特性

Question

我正在尝试运行以下Netlogo过程：

to spread-virus
  ask turtles with [infected?]
      [ ask link-neighbors with [not infected?]
        [ if random-float 100 < virus-spread-chance
          [ become-infected ] ] ]
end

我不仅要ask turtles with [infected?]，还要with [immune?]。除了immune之外，如何添加第二个特征（infected）？

Answer 1

来自@alan，with [infected? or immune?]
