如何阻止图像在列表中循环

Question

我正在做一个3场比赛式的游戏。我是pygame的初学者，已经设法随机生成了一个棋盘，这样每个playthrough都是不同的。目前我唯一的问题是，我的瓷砖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。有人能帮忙吗？你可以在谷歌硬盘上找到我用过的图片！我什么都感激

问题是每帧都会重新创建电路板

在应用程序循环之前生成电路板一次。清除显示屏并在应用程序循环中显示电路板：

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()
