在设置时创建一次海龟，而不是在每个节拍中创建海龟

Question

在我的程序中，海龟品种CO2s的初始浓度为10，海龟品种葡萄糖的初始浓度从10开始，每刻度增加10个(如设置-馈送过程中所述)。to go程序包括一种海龟繁殖的细菌，这种细菌在每只扁虫身上都会吃掉CO2s和葡萄糖。问题是，在我目前的代码中，两种海龟，CO2s和葡萄糖，都会增加每一次滴答。我当前输出的Excel如下所示：

​

​

我希望我的Excel输出可以是这样的：

对这个问题有什么意见和建议吗？

Answer 1

没有创建glucose_mass，你的过程count_glucose是一个累积的海龟总和，这就是你的文件中输出的内容。但你的问题表明，你认为这是在报告葡萄糖制剂的数量。

to count_glucose
  set total_glucose (total_glucose + sum [glucose_mass] of glucose)
end

如果您真的想计算葡萄糖制剂的数量，那么您需要count glucose

file-print count glucose

而不是：

file-print total_glucose
