如何多次迭代同一个草图 -(处理) [英] How to iterate the same sketch multiple times -(processing)

问题描述

我在 Processing 3.5.4 中编写了一个程序.其基本结构如下:

I wrote a program in Processing 3.5.4. It's basic structure is as follows:

int SOMEINITIALSTUFF;
Class[] classArrays = new Class[];

void setup() {
  Sets up the simulation to run;
  size(1200, 700);
}

void draw() {
  background(255, 200, 200);
  Runs Simulation;
  Collects data;
}

这运行良好.我想做的是多次运行这个程序来收集一些统计数据.

This runs fine. What I would like to do is run this program multiple times to gather some statistics.

我不知道如何做到这一点.我想基本上将整个代码放入一个循环中，并收集它为每次迭代创建的数据，可能会运行数千次.我已经试过了，但它破坏了程序.有什么建议吗?

I can't figure out how to do this. I want to essentially put this whole code into a loop, and collect the data it creates for each iteration, possibly running it thousands of times. I've tried just that, but it breaks the program. Any suggestions?

推荐答案

您可以通过几个简单的步骤完成此操作，其中一些可能需要进行一些重构:

You can do this with a couple simple steps, some of which may require some refactoring:

1. 确定定义模拟结束的条件.
2. 设置一个仅在模拟完成后运行的方法.我们将其称为 Reset() 以简化操作.
3. 在Reset() 中，确保重新初始化所有在创建时初始化的全局变量.将它们设置回初始值.
4. 在Reset()中，运行setup().
5. 让自然顺其自然，您的应用程序已被诱骗重新开始.

1. Determine the conditions which define the end of the simulation.
2. Set un a method which will run only once the simulation is done. We'll call it Reset() to make things easier.
3. In Reset(), make sure that you reinitialize any global variables which is initialized at their creation. Set them back to their initial value.
4. In Reset(), run setup().
5. Let nature follows it's course, your application has been tricked into beginning anew.

当然，您可能希望组织您的代码，以便您收集的信息不会被删除，无论是通过将其保存到不同的文件/每次运行新模拟时将其附加到文件中，还是通过保留它在一个不会被重置的全局变量中.我没有足够的细节来详细说明这方面，但我想你会理解我提出的想法.

Of course, you may want to organize your code so the information you gather won't be erased, whether by saving it to a different file/appending it to a file at every time you run a new simulation, or by preserving it in a global variable which won't be reset. I don't have enough details to elaborate on this front, but I think you'll understand the idea I'm advancing.
