通过预先修补NetLogo获得多个补丁

Question

patch-ahead distance在前面报告单个补丁。

如何在该领先点的半径范围内获得一组补丁？

Answer 1

您可以让记者为您执行此操作，例如：

to-report patches-ahead [ rad dis ] ; turtle reporter
  report [patches in-radius rad] of patch-ahead dis
end

请注意，它必须由乌龟调用-例如：

to setup
  ca
  crt 1
  reset-ticks
end

to go
  ask patches [ 
    set pcolor black
  ]
  ask turtles [
    rt random 61 - 30
    fd 1
    ask patches-ahead 3 7 [ 
      set pcolor white
    ]
  ]
  tick
end
