Conway's Game of Life Python / PyGame 打印错误

如何解决Conway's Game of Life Python / PyGame 打印错误

我是 python 和 PyGame 的新手，想通过做我认为是一个简单的项目来获得一些经验。我不知道我的错误是在我的游戏逻辑中还是在我的 PyGame 打印中。我创建了两个函数，一个用随机值填充网格，另一个用“Blinker”填充网格。程序运行没有错误，但是没有遵守游戏规则。例如，当设置了“blinker”时，程序的第二帧清除屏幕而不是旋转“blinker”。 任何诊断此问题的帮助将不胜感激！

解决方法

您的 count_neighbors 函数不会迭代正确的单元格。 range(-1,1) 迭代 {-1,0} not {-1,1}。

改为使用：

def count_neighbours(grid,x,y):
    count = 0
    for i in range(-1,2):
        for j in range(-1,2):
            count += grid[x + i][y + j]
    return count - grid[x][y]
