如何阻止图像在列表中循环

Question

我正在制作一款三消风格的游戏。我是 pygame 的初学者，我设法随机生成了一个棋盘，因此每次游戏都是不同的。我目前唯一的问题是我的图块似乎在我为每个图像创建的列表中不断循环。我尝试添加一个 for 循环来删除正在生成的每个元素，但我似乎没有做任何更改。有人可以帮忙吗？您可以找到我在 google 驱动器中使用的图像！我很感激任何事情！

    gameBoard = generateBoard()

    showBoard(gameBoard)


    pygame.display.update()

pygame.quit()

问题是每帧都会重新创建棋盘。

在应用程序循环之前生成一次电路板。清除显示并在应用程序循环中显示板子：

gameBoard = generateBoard()

while running:

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False

    screen.blit(background_img, (0,0))
    showBoard(gameBoard)
    pygame.display.update()

pygame.quit()
