Question

我正在尝试重新制作飞扬的鸟我想知道如何让我的鸟继续跳跃？当我点击空格时

这是我现在的跳跃

        if collide:
            if keys[pygame.K_SPACE]:
                bird1.isJump = True
            bird1.fall = 0


    else:
        if bird1.JumpCount > 0:
            bird1.y -= (bird1.JumpCount*abs(bird1.JumpCount))*0.4
            bird1.JumpCount -= 1
        else:
            bird1.JumpCount = 10
            bird1.isJump = False

如果你想测试一下，我的完整代码都是正确的

你必须改变两件事:

即使不与地面碰撞，鸟也可以跳跃。

保持状态 bird1.isJump如果当鸟开始下降时空间仍然被按下。

while run:
    # [...]

    keys = pygame.key.get_pressed()

    # bird moving
    bird1.x += bird1.speed
    if not bird1.isJump:
        # [...]

        # the bird is allowed to jump even if it is not colliding:
        if keys[pygame.K_SPACE]:
            bird1.isJump = True

        if collide:
            bird1.fall = 0

    else:
        if bird1.JumpCount > 0:
            bird1.y -= (bird1.JumpCount*abs(bird1.JumpCount))*0.4
            bird1.JumpCount -= 1
        else:
            bird1.JumpCount = 10
            
            # if K_SPACE is pressed, then the bird keeps jumping
            if not keys[pygame.K_SPACE]:
                bird1.isJump = False
