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周围的部分？有任何想法吗？我在这里标注了“SIMULATION CODE”
我不需要你为我做这件事，我只需要提示如何处理这部分过程，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。

int generation = 0;
DrawWorld(worldwidth, worldheight, cellcolour, backgroundcolour, generation);
// SIMULATION CODE HERE!

首先用简单的英语写下规则：
您现在的工作是将这些简单的英语语句转换为代码。要使代码生效，您必须知道它需要什么输入。因此，我们需要查看语句以查看它的计算结果：
基于此分析，我们现在知道我们的代码需要两个输入：
为了计算细胞是否存活，我假设你看看currentgeneration[r,c]。
要计算有多少相邻单元格存活，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，您可以编写一个接收两个输入的函数，并确定单元格是否处于活动状态：
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);
}
我会再添加2个数组，一个跟踪哪些细胞存活（bool），另一个跟踪一个细胞有多少个邻居（int）。
在每次更新时，循环通过活动单元并在其周围的位置添加邻居阵列。完成后，根据该位置的邻居数量，简单地杀死，生成或保留单元格。
以下是JavaScript中该程序的示例：
添加邻居
// Iterate through the alive array
// If the cell at that position is alive...
if (alive[x][y] == true)
{
for (X = -1; X <= 1; X++)
{
for (Y = -1; Y <= 1; Y++)
{
// Get the coordinates of the positions around it
dx = x + X;
dy = y + Y;
// If the coordinates are valid
if (dx >= 0 && dy >= 0 && dx < ROW && dy < COLUMN)
{
// Increment the neighbour array
neighbours[dx][dy] += 1;
}
}
}
}
更新alive数组
// If the cell is alive...
if (alive[x][y] == true)
{
// Remove the bias (the UpdateNeighbour function adds neighbour in a 3x3 area, not only the neighbours.)
numNeighbours -= 1;
// If it has less than 2 neighbours...
if (numNeighbours < 2)
{
// It dies
alive[i][y] = false;
}
// If it has 2 or 3 neighbours...
else if(numNeighbours < 4)
{
// It survives
alive[i][y] = true;
}
// If it has more than 4 neighbours...
else if (numNeighbours >= 4)
{
// It dies
alive[i][y] = false;
}
}
// If the cell isn't alive but has exactly 3 neighbours...
else if (alive[x][y] == false && numNeighbours == 3)
{
// Spawn new cell
alive[x][y] = true;
}
