netlogo - 通过 patch-ahead NetLogo 获取多个补丁

Question

patch-ahead distance 报告前面的单个补丁。

如何获得该前方点半径内的一组补丁？

Answer 1

您可以让记者为您做这件事，例如:

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

请注意，它必须由海龟调用 - 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
