pygame中的图像移动（崩溃pygame）

Question

我想做一个游戏，当这个循环运行时，它会崩溃

while poterbar_hunt_pone == True and ptwo_shot == True:

            if poterbarx < xone+carone_width:
                poterbar_dir = "right"
                poterbarx_c = 20
            else:
                poterbar_dir = "left"
                poterbarx_c = -20

            if poterbary+poterbarh < yone:
                poterbary_c = 20
            else:
                poterbary_c = -20

            if poterbarx <= xone+carone_width and poterbarx+poterbarw >= xone:

                if poterbary+poterbarh >= yone and poterbary <= yone+carone_height:
                    xone_change = random.randrange (-20, 20)
                    yone_change = random.randrange (-20, 20)
                    poterbar_hunt_pone = False
                    ptwo_shot = False
                    poterbarx = -100
                    poterbary = -100

当这两个值都为真时，pygame崩溃了，我想是在波特的运动中。 如果你们中有人知道是什么导致pygame崩溃请告诉我

您缺少pygame.display.update()。你知道吗

将此添加到代码的最底部，使其看起来像：

while poterbar_hunt_pone == True and ptwo_shot == True:

            if poterbarx < xone+carone_width:
                poterbar_dir = "right"
                poterbarx_c = 20
            else:
                poterbar_dir = "left"
                poterbarx_c = -20

            if poterbary+poterbarh < yone:
                poterbary_c = 20
            else:
                poterbary_c = -20

            if poterbarx <= xone+carone_width and poterbarx+poterbarw >= xone:

                if poterbary+poterbarh >= yone and poterbary <= yone+carone_height:
                    xone_change = random.randrange (-20, 20)
                    yone_change = random.randrange (-20, 20)
                    poterbar_hunt_pone = False
                    ptwo_shot = False
                    poterbarx = -100
                    poterbary = -100
    pygame.display.update() # You have to update display
