python持续发射子弹_Python外星人入侵项目-重构代码，使得空格键按下后可以连续发射子弹...

1，首先在ship

class Ship():

def __init__(self, ai_settings, screen):

"""初始化飞船并设置其初始位置"""

--snip--

# 空格和发射标志

self.space = False

self.bullets_fire = True

2，首先重构代码，判断空格键按下和放开状态

def check_events(ship):

"""响应按键和鼠标事件"""

for event in pygame.event.get():

if event.type == pygame.QUIT:

sys.exit()

elif event.type == pygame.KEYDOWN:

check_keydown_events(event, ship)

elif event.type == pygame.KEYUP:

check_keyup_events(event, ship)

def check_keydown_events(event, ship):

"""响应按键"""

if event.key == pygame.K_RIGHT:

ship.moving_right = True

elif event.key == pygame.K_LEFT:

ship.moving_left = True

elif event.key
