Netlogo缩放颜色，具有不同的值

Question

在NetLogo中，我使用了以下一行的scale-color：

ask patches [set pcolor scale-color green potential min-potential max-potential]

潜力是一个总是在变化的补丁变量。问题是：如何获得此变量的最小值和最大值？

Answer 1

那就是：

我建议您在let min-potential min [ potential ] of patches let max-potential max [ potential ] of patches 块之前将它们存储在本地变量中，以便每次修补程序执行ask操作时都不必重新计算它们。
