python - 如何修复“pygame中的背景故障”连续滑动背景？

Question

我为我的 pygame 添加了连续滚动的背景，以显示玩家总是向前运行的效果。它正在工作，但问题是它不是很顺利，每秒都有小故障。我需要做什么来解决这个问题？

主游戏循环

在每帧的主循环背景对象更新位置中，左侧为 5 个像素，每帧都会发生 x - 5

def game_window():
    global warningCount, warningText
    player_one.isDead = False
    gameOver = 20
    run = True
    while run:
        clock.tick(FPS)
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                sys.exit()
            if event.type == USEREVENT + 2:
                r = random.randrange(0, 2)
                if r == 0:
                    enemy_list.append(Enemy(800, 318, 64, 64, GAMESPEED))
                else:
                    spike_list.append(Spike(800, 0, 48, 330))
            player_one.eventHandler(event)
        for enemy in enemy_list:
            enemy.update()
            if enemy.x < 0:
                enemy_list.pop(enemy_list.index(enemy))
            if enemy.falling:
                gameOver -= 1
                if gameOver <= 0:
                    warning[0] = 20
                    warning[1] = 'GAME OVER'
                    main_window()
        for spike in spike_list:
            spike.update()
            if spike.x < 0:
                spike_list.pop(spike_list.index(spike))
            if spike.falling:
                gameOver -= 1
                if gameOver <= 0:
                    warning[0] = 20
                    warning[1] = 'GAME OVER'
                    main_window()
        player_one.update()
        bg_one.bgUpade()
        bg_two.bgUpade()
        redrawGameWindow()

游戏窗口更新

def redrawGameWindow():
    global warningCount, warningText
    bg_one.draw(win)
    bg_two.draw(win)
    player_one.draw(win)
    for enemy in enemy_list:
        enemy.draw(win)
    for spike in spike_list:
        spike.draw(win)
    if warning[0] > 0:
        text_surface = bitter.render(warning[1], 1, COLOR_RED)
        win.blit(text_surface, (int(W / 2 - text_surface.get_width() / 2), 20))
        warning[0] -= 1
    pygame.display.update()

背景类

class background(object):
    def __init__(self, x, y, vel, index):
        self.x = x
        self.y = y
        self.index = index
        self.vel = vel

    def draw(self, win):
        win.blit(bg[self.index], (self.x, self.y))
        if self.x < -800:
            self.x = 800

    def bgUpade(self):
        if not player_one.isDead:
            bg_one.x -= bg_one.vel
            bg_two.x -= bg_two.vel
