当我的图像在pygame中流血之后，它掉了，我不知道为什么

标签： python image pygame

我已经加载了图像和所有内容，但是现在，当我调用它时，它太大了，我无法更改大小，它也不会停留在我调用它的位置，也看不到哪里出错了，为什么它会继续下降...图像会发白并显示出来，但是在错误的位置却刚刚下降，我可以移动这只猫和所有的猫，但是它正在下降并且不应该。这有点像游戏中的对象从屏幕顶部掉落，然后在顶部重新加载，但随后不重新加载。猫需要先流血并在地上，但不是。

该代码似乎正在处理“跳转”代码，而没有实际接收到该事件。阅读事件循环：

while run:
    clock.tick(27)

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    keys = pygame.key.get_pressed()

    if keys[pygame.K_LEFT] and x > vel:
       # do left
    elif keys[pygame.K_RIGHT] and x < W - width - vel:
        #do right
    else:
        # neither left nor right

    if not(isJump):
        y += vel                      # <--- THIS PART
        if keys[pygame.K_SPACE]:
            # start a new jump

如果未进行跳转，则y每帧增加vel（5）。
