Question

我正在制作一个简单的游戏（“Dodger＆＃39;游戏”的副本），游戏运行，但什么也没有显示。我有一个while循环运行，为什么没有出现？这是间距，图像本身的问题，还是我只是忽略了什么？

Answer 1

通常我使用pygame.display.flip()而不是pygame.display.update()

Answer 2

您在脚本中调用startGame()，如下所示：

def startGame():
    while True:
        for event in pygame.event.get():
            if event.type == QUIT:
                terminate()
            if event.type == KEYDOWN:
                if event.key == K_ESCAPE:
                    terminate()
                return

游戏停留在while循环中，直到你按下一个键。

这是您当前的问题，但也有其他错误，例如

def terminate():
    if pygame.event() == QUIT:
        pygame.quit()

pygame.event()无法调用。也许你想在这里传递一个事件作为参数？

还

pygame,mouse.set_pos(playerRect.centerx,playerRect.centery)

,代替.
