PyGame中的跳跃问题很难回答

Question

我有一个相当复杂的程序，可以让忍者在屏幕上奔跑。当你按下按钮时，他会滑倒，然后又回来。当你向上压的时候，他应该跳下来然后跑。但是忍者一直在跳，唯一能跳出来的方法就是你在地面上滑行。他只有在地上才能滑倒，这很好，但我不知道他为什么一直弹跳

我不知道如何解决这个问题，但我在代码中尝试了一些东西和开关，但没有任何帮助。下面的代码很复杂，必须包含图像。我不希望你得到图像并测试它，我只是希望专业人士检查一下，看看他们是否能看到我没有看到的东西

我认为这是代码中存在问题的主要部分：

if not (isjump):
        if Counter > 17:
            if keys[pygame.K_UP]:
                isjump = True
            isrunning = False
            isslide = False
            Counter = 0
else:
    if jumpCount >= -10:
        neg = 1
        if jumpCount < 0:
            neg = -1
        y -= (jumpCount ** 2) * 0.5 * neg
        jumpCount = jumpCount -1
    else:
        isJump = False
        jumpCount = 10  

以下是全部代码：

    global isrunning
    win.blit(bg, (bgX, 0))  # draws our first bg image
    win.blit(bg, (bgX2, 0))

    if isrunning == True:
        win.blit(Run[imagerun],(x, y))

很抱歉，我把整个代码都放进了IDK，但我知道错误发生在哪里。我希望有人能帮忙。这是我做过的最难的程序，所以它非常混乱。请随意评论其他把事情搞砸的事情。非常感谢所有善良的人去帮助像我这样的人。谢谢你，一个在互联网上随机出现的家伙
