Netlogo 只要看看代码就可以了。您需要尽可能地消除复杂性，然后使用形状、颜色和大量打印语句来查看每个命令是否都在执行您认为应该执行的操作。复杂的工作代码几乎总是从简单的工作代码演变而来

因此，完全摆脱PlayersB（注释掉代码），只创建5个playersa，并在处理每个步骤时更改颜色和形状，以确认其工作正常。编辑器允许您使用ctrl-；注释掉整个代码块，或者立即取消注释它们，所以在开始一个步骤时，尽可能注释掉所有内容，然后取消注释下一部分，让它开始工作，等等

当您最终使一切正常工作时，您可以注释掉您在开发中使用的所有打印语句

无论如何，我重构了您的代码，添加了许多注释，添加了许多打印语句，最后让它运行起来。如果您运行justsetup并查看视图，您将看到我所说的网络。（我关闭了视图中的换行，以便网络看起来正确。）

这是我对你的代码的修改。它会在每一步后打印出每个玩家的“我的列表”中的内容，这样你就可以一眼看出它是否在做你想做的事情。（事实并非如此。）

我将who编号作为标签添加到视图中的每个玩家，以便您可以了解我的意思

它会产生有用的输出，如：

让我们确认列表已更新。这是我的名单 播放者a[[5 5 5 10][0 0 0 0 0][0 8 8 8][0 0][0 9]]

在您尝试修复“go部分”之前，请先执行设置步骤以正确运行并生成所需的网络

有一件事-没有两只海龟可以有相同的who编号，即使它们是不同的品种：问playerA 0会影响同一只海龟问playerB 0，我相信。谢谢韦德。不幸的是，我不太熟悉使用who。我想做的是，当球员在网络内传球并追踪气球的路径时，给一个分数——没有两只乌龟可以有相同的who号码，即使它们是不同的品种：问playerA 0会影响同一只乌龟a问playerB 0，我相信。谢谢韦德。不幸的是，我不太熟悉使用who。我想做的是，当球员在网络内传球并追踪球的路径时，给一个分数
