如何检测网格单元格中的点击并更改其颜色？

对 python 相当陌生，并试图重新创建我在学校玩的游戏。对于这个游戏，我需要随机产生这些炸弹，如果击中，这些炸弹会将您的银行帐户减少到零，并将方块的炸弹方块的颜色更改为红色（而安全的则变为绿色）。 我遇到的问题是：

• 我想将炸弹方块的颜色改为红色，但他们不这样做，它们只是保持白色，但是，安全的确实会变成绿色
• 另外对于炸弹的坐标，我想确保这些坐标都不相等，我想让它重新滚动重复的坐标

任何有关这些的帮助将不胜感激

                             color,
                             [(margin +
                               width) * column + margin,
                              (margin + height) * row + margin,
                              width,
                              height])
 
    
    clock.tick(60)
    pygame.display.flip()
 
pygame.quit()

首先有一个错字：color = red而不是colour = red.

无论如何，你必须改变你的游戏逻辑。对于未单击的单元格使用值 0 和 2，对于已单击的单元格使用值 1 和 3。将网格的所有字段初始化为 0。通过将 2 分配给随机单元格，在网格上放置随机炸弹。
当单击值为 0 的单元格时，将其值更改为 1。当单击带有炸弹（值 2）的单元格时，将其值更改为 3：

while not done:
    # [...]

    for event in pygame.event.get():  
        # [...]

        elif event.type == pygame.MOUSEBUTTONDOWN:
            # Change the x/y screen coordinates to grid coordinates
            column = event.pos[0] // (width + margin)
            row = event.pos[1] // (height + margin)
            if grid[row][column] == 2:
                print('Boom')
                grid[row][column] = 3
            if grid[row][column] == 0:
                grid[row][column] = 1
                print("Click ", event.pos, "Grid coordinates: ", row, column)

当您绘制网格时，所有单元格都必须绘制为白色。除了单元格的值为 1 之外。在本例中，它的颜色为绿色。如果单元格的值为 3，则其颜色为红色：

while not done:
    # [...]

    #Draw the grid
    for row in range(10):
        for column in range(10):
            color = white
            if grid[row][column] == 1:
                color = green
            elif grid[row][column] == 3:
                color = red
            cell_rect = ((margin + width) * column + margin, (margin + height) * row + margin, width, height)
            pygame.draw.rect(gameD, color, cell_rect)
