添加特性與程序的NetLogo

Question

我試圖運行下面的NetLogo過程：

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

我想不僅ask turtles with [infected?]，還有那些with [immune?]。我怎麼能在另外的第二特性（immune）添加到infected？

Answer 1

信用損失@alan，with [infected? or immune?]
