Question

我的netlogo模型遇到了一些麻烦，我希望有人可以帮助我度过难关。

我有一个带有特定属性的补丁的世界，代表公园，建筑物，街道（2种类型的小型和大型）等。我希望我的乌龟移向特定点（我设法做到了）。但我希望海龟只能在代表街道的斑块上移动，具有特定于它们的属性，蓝色和3或4的值。你是这样做的吗？

以下是我建立世界的方式：

Answer 1

为了防止龟踩到任何蓝色斑块上，你可以这样做：

ifelse [pcolor = blue] of patch-ahead 1
  [ fd 1 ]
  [ ...do something else here... ]

但是您需要决定“做其他事情”部分是什么。在那种情况下你想要发生什么......？

让乌龟移动具有特定属性的补丁
