问题描述

所以我正在尝试编写康威的生命游戏，但我不知道如何处理它检查它们的部分？有任何想法吗？我已将区域标记为“此处的模拟代码”

我不需要你为我做这件事，我只需要一个关于如何处理这部分过程的提示，因为我不知道如何检查阵列周围的区域，看看有多少活点存在，等等.

解决方案

首先用简单的英语写下规则：

  • 任何少于两个活邻居的活细胞都会死亡，就像人口不足一样。
  • 任何有两三个活邻居的活细胞都可以活到下一代。
  • 任何有超过三个活邻居的活细胞都会死亡，就像人口过剩一样。
  • 任何只有三个活邻居的死细胞都会变成活细胞，就像通过繁殖一样。

您现在的工作是将这些简单的英语语句转换为代码。要使代码正常工作，您必须知道它需要哪些输入。所以我们需要检查这些语句以查看它的计算结果：

  • 任何少于两个活邻居的活细胞都会死亡，就像人口不足一样。
  • 任何有两三个活邻居的活细胞都可以活到下一代。
  • 任何有超过三个活邻居的活细胞都会死亡，就像人口过剩一样。
  • 任何只有三个活邻居的死细胞都会变成活细胞，就像通过繁殖一样。

基于此分析，我们现在知道我们的代码将需要两个输入：

  1. 它需要知道当前单元格是否还活着
  2. 它需要知道有多少相邻的细胞是活着的。

要计算细胞是否还活着，我假设你会查看currentgeneration[r,c].

要计算有多少相邻的细胞是活着的，您需要查看以下所有内容：

currentgeneration[r-1,c-1] 
currentgeneration[r-1,c  ] 
currentgeneration[r-1,c+1] 
currentgeneration[r  ,c-1] 
currentgeneration[r  ,c  ] 
currentgeneration[r  ,c+1] 
currentgeneration[r+1,c-1] 
currentgeneration[r+1,c  ] 
currentgeneration[r+1,c+1]

因此，您的代码需要检查所有这些元素并计算活动的元素。

然后，您可以编写一个函数，该函数接受两个输入并确定一个单元格是否还活着：

bool IsAlive(bool wasAlive, int count)
{
    if (wasAlive && count<2) return false;                 // Any live cell with fewer than two live neighbors dies, as if by underpopulation.
    if (wasAlive && (count==2 || count == 3)) return true; // Any live cell with two or three live neighbors lives on to the next generation.
    if (wasAlive && count>=3) return false;                // Any live cell with more than three live neighbors dies, as if by overpopulation.
    if (!wasAlive && count == 3) return true;              // Any dead cell with exactly three live neighbors becomes a live cell, as if by reproduction.
}

现在我们可以编写一个方法来检索要传递给函数的数据：

bool IsAlive(int r, int c)
{
    var count = currentgeneration[r-1,c-1] 
              + currentgeneration[r-1,c  ] 
              + currentgeneration[r-1,c+1] 
              + currentgeneration[r  ,c-1] 
              + currentgeneration[r  ,c  ] 
              + currentgeneration[r  ,c+1] 
              + currentgeneration[r+1,c-1] 
              + currentgeneration[r+1,c  ] 
              + currentgeneration[r+1,c+1];
    var isAlive = ( currentgeneration[r,c] == 1);
    return IsAlive(isAlive, count);
}
