当我尝试运行pygame窗口时，它变得非常滞后。到目前为止，我有 132 行代码，我还有很多东西要添加。在测试运行时，我注意到当我添加以下代码时，游戏滞后了
class Game:
def __init__(self):
self.win = pygame.display
self.d = self.win.set_mode((1200, 600))
self.win.set_caption(" JUMP ")
self.timee = 0
def write(self, size, writing, color, x, y):
font = pygame.font.SysFont("nirmalauisemilight", size)
text = font.render(writing, True, color)
self.d.blit(text, (x, y))
def game_over(self):
if b.y >= ba.y - b.side and self.timee > 5:
while True:
self.write(200, "GAME OVER", (255, 0, 0), 20, 50)
self.write(50, "Press enter to satart a new game", (0, 255, 0), 100, 400)
pygame.event.get()
keys = pygame.key.get_pressed()
if keys[pygame.K_RETURN]:
main()
g.win.flip()
和
def draw(self):
if g.timee < 5:
pygame.draw.rect(g.d, (0, 255, 0), (self.x, self.y, self.width, self.height))
else:
pygame.draw.rect(g.d, (255, 0, 0), (self.x, self.y, self.width, self.height))
g.timee是我做的一个变量，所以我可以在游戏的卡坦时间后执行一些函数。g.timee在主循环中递增 0.01。我也尝试使用时间模块的time.time()功能，但它更加落后于游戏。有关如何减少滞后的任何建议将不胜感激。

我想通了。 这是因为我的pygame.time.Clock().tick(60)在游戏循环中。不知道为什么这会导致滞后，但对于可能遇到相同问题的任何人，请不要将其放在主循环中。
我没有看到任何明显的东西，所以我的猜测是由于你的延时机制。 你能发布你是如何延迟的吗？ 延迟时间不得干扰渲染/绘制。 下面是一个示例。
def gameloop1(): # delay interfering with drawing
# delay by some long loop
i = 0
while i < 10000:
i = i + 1
if i == 10000:
# execute some function
# draw stuff
i = 0
def gameloop2():
i = i + 1
if i == 10000:
# execute some function
# draw stuff
在示例中，gameloop1 在每次抽奖之前都会有一些延迟，而 gameloop2 不会并且仍然允许您执行延迟。 也不要将这种增量用作延迟机制，因为它会因不同的系统速度而异，请改用时基。
