python - Pygame 双跳

Question

我几乎要放弃了，所以我需要帮助。我正在尝试制作一个具有双跳的简单平台游戏......我一直在兜圈子，试图找到有用的东西到目前为止，我最好的想法是比较刻度数，但每次我得到一些想法时，我都会设法把它搞砸，但我不知道如何......有简单的方法吗？

请忽略任何不必要的变量，这只是一个示例

Clock=pygame.time.Clock()

t=0
a=0
b=0
f=0
m=0

while True:
    Clock.tick(180)
    for event in pygame.event.get():
        if event.type == QUIT:       
            pygame.quit()
            sys.exit()
        if event.type == KEYDOWN:
            if event.key==K_SPACE and b==0:
                movey=-1
                a=1
                t=pygame.time.get_ticks()
            if event.key==K_SPACE and b==1:
                f=pygame.time.get_ticks()
                if f<=t+238:
                    a=1
                else:
                    pass
        if event.type == KEYUP:
            if event.key==K_SPACE and b==0 and a==1:
                a=0
                b=1
            if event.key==K_SPACE and b==1 and a==1:
                m=1
                b=3
                s=y
    if m==1:
        y+=movey
        if y==s-32:
            m==0

    elif y<=312 and movey==-1:
        movey=+1
    elif y==344 and movey==+1:
        movey=0
        a=0
        b=0
    else:
        y+=movey

现在这就是我正在尝试的......

g = -1  # gravity

            self.y_speed = 9  # a big jump
            self.jumping = 1  # change jumping status

        elif self.jumping == 1 and self.y_speed <= 0:

        if self.y == 0:  # on the ground again!
            self.jumping = 0  # reset jump
            self.y_speed = 0  # reset speed
