Pygame显示10x10不同颜色正方形的网格，如b所示

Question

我需要一个pygame项目的帮助。现在它应该只显示一个10x10的不同颜色的正方形网格，但是它只显示黑色。它没有给我任何错误信息。你知道吗

这是我的密码，有人能告诉我我做错了什么吗？你知道吗

while fps:
    pygame.display.update()
    fpsClock.tick(FPS)

pygame.display.update()

Answer 1

您的整个程序都被困在第一个while循环中，因为它无法中断。如你所见：

running = True
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.display.quit()
            sys.exit()

离开的唯一方法，就是离开。你知道吗

您应该做的是合并两个while循环。你知道吗

running = True
FPS = 30
fpsClock = pygame.time.Clock()
while running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.display.quit()
            sys.exit()
    pygame.display.update()
    fpsClock.tick(FPS)

旁注：不建议使用pygame在脚本中间调用sys.exit()。您应该改为running = False，让程序正常退出。你知道吗

另一个旁注：你不需要两帧时钟。去掉第一个：FPSCLOCK = pygame.time.Clock()。而且playerPosition = currentLevel是没有用的，因为代码中没有任何地方使用它。你知道吗
