所以我尝试在我的游戏中添加一个随机掉落物,它会生成一个导弹包,然后玩家可以拾取它,它会在玩家的库存中添加一枚导弹,但是在创建 'MissilePack
对象并更新我的 Spawner 类以随机生成导弹包之后Pygame 窗口完全冻结并且不显示任何错误消息,所以我不知道该怎么做,任何帮助将不胜感激。
inventory=[]
class MissilePack(games.Sprite):
speed = 1.7
image = games.load_image('MissilePack.bmp')
global inventory
def __init__(self, x,y = 10):
""" Initialize a missilepack object. """
super(MissilePack, self).__init__(image = MissilePack.image,
x = x, y = y,
dy = MissilePack.speed)
def update(self):
""" Check if bottom edge has reached screen bottom. """
if self.bottom>games.screen.height:
self.destroy()
def handle_caughtpack(self):
inventory.append('missile')
这是我的 Spawner 类的一部分,它将随机生成 Missile Pack 供玩家拾取。
def update(self):
""" Determine if direction needs to be reversed. """

self.dx = -self.dx

self.dx = -self.dx
self.check_drop()
self.drop_missile()
def drop_missile(self):
"""Randomely drops a missile pack for the player to use"""
while True:
dropmissile = random.randrange(0, 10)
if dropmissile == 5:
missilepack = MissilePack(x = self.x)
games.screen.add(missilepack)
