Pygame：游戏不显示任何内容，尽管有'while'循环

Question

我正在开发一个简单的游戏（“Dodger”游戏的半副本），游戏运行，但没有显示任何内容。我有一个while循环正在运行，为什么什么都没有出现？是间距、图像本身的问题，还是我只是忽略了某些东西？

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

游戏一直停留在while 循环中，直到您按下一个键。

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() 不可调用。也许你想在这里传递一个事件作为参数？

还有

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

, 而不是.
