当我点击太空游戏时，如何让我的鸟继续跳跃？

Question

我在试着重新创造一只扑翼鸟，我想知道我该如何让我的鸟继续跳跃？当我点击空格时 video 这是我现在要跳的

        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

如果你想测试的话，我的全部代码都是矩形的

import pygame
pygame.init()

#this is screem height
window = pygame.display.set_mode((500,500))

#know we put screem name
pygame.display.set_caption("Noobs Flappy Bird Game")

    else:

        else:

            bird1.isJump = False




            
    redrawwindow()
    pygame.display.update()
pygame.quit()

你必须改变两件事：

• 即使鸟没有与地面相撞，也允许它跳跃
• 如果鸟开始下落时仍按下空格，则保持状态bird1.isJump

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
