NETLOGO：计算特定半径之外的补丁

Question

我想从色块半径末端开始向外计算特定颜色的色块。有 in-radius 命令，但它考虑了面片中心与其半径之间的 space，但我希望排除此 space 并开始计算半径结束的位置。感谢您的帮助。

使用 member? 到 return 仅由非 in-radius 补丁组成的补丁集的记者怎么样？

to setup
  ca
  ask n-of 10 patches [ set pcolor white ]
  crt 1 [ 
    setxy random-pxcor random-pycor 
    set color red
    set size 2
  ]
  reset-ticks
end

to go
  ask turtles [
    ask patches in-radius 5 with [ pcolor = black ] [ set pcolor black + 2 ]
    print count ( patches-outside-radius 8 ) with [ pcolor = white ]
  ]
end

to-report patches-outside-radius [ radius ]
  let inrad patches in-radius radius
  report patches with [ not member? self inrad ]
end
