这是使用3个类的第一次尝试，给我这个错误：'StatusDrops'对象没有属性'rect'。但是我为外星人使用了完全相同的方法，到目前为止效果很好
丢弃父类
class Drops(pygame.sprite.Sprite):
def __init__(self, dw, dh, x, y):
super().__init__()
self.display_width = dw
self.display_height = dh
self.posx = x
self.posy = y
self.speedx = 3
self.speedy = 5
self.pickedUp = 0
#Set Rotation
def setRotation(self):
self.rotationx = self.rotationy = random.randrange(-1, 1)
if self.rotationx == 0:
self.setRotation()
#Set both side's rotation chance
def setRotationChance(self):
self.rotationxChance = random.randrange(1, 151)
self.rotationyChance = random.randrange(1, 151)
#Change rotation side
def changeRotation(self):
#Side steps rotation
if self.rotationxChance == 1:
if self.rotationx == 1:
self.rotationx = -1
else:
self.rotationx = 1
#Forward steps rotation
if self.rotationyChance == 1:
if self.rotationy == 1:
self.rotationy = -1
else:
self.rotationy = 1
#Movement
def move(self):
self.rect.x += (self.rotationx * self.speedx)
self.rect.y += (self.rotationy * self.speedy)
#Kill if picked up or went of the boundaries
def checkStatus(self):
if self.pickedUp == 1:
self.kill()
if self.rect.x > self.display_width or self.width < 0:
self.kill()
elif self.rect.y < 0 or self.rect.y > self.display_height:
self.kill()
StatusDrop子类（由于出现错误，我没有继续使用awerDrop）
class StatusDrops(Drops):
def _init__(self, dw, dh, x, y):
super().__init__(dw, dh, x, y)
self.type = self.setType()
self.setAttributes(self)
self.rect = self.image.get_rect(center = (self.posx, self.posy))
self.image.set_colorkey(YELLOW)
self.setRotation()
def setType(self):
x = 1#random.randrange(1, 5)
return x
#Set attributes, what kind of status will upgrade(health, stamina, tenacity, nano shell)
def setAttributes(self):
#Hero increase's stamina(max health)
if self.type == 1:
self.image = staminaIcon
self.width = 28
self.height = 23
#Hero heal, max heal income = 30% of stamina
elif self.type == 2:
self.image = healIcon
self.width = 28
self.height = 23
#hero increases resistance to slow and stun(lower duration) up to 30%
elif self.type == 3:
self.image = tenacityIcon
self.width = 28
self.height = 23
#hero increases resistance to incoming damage(armor) up to 50%
elif self.type == 4:
self.image = nanoshellIcon
self.width = 28
self.height = 22
self.image = staminaIcon
self.width = 28
self.height = 23
def update(self):
#Movement
self.move()
#Call both sides rotation chances
self.setRotationChance()
self.changeRotation()
#Check drop status
self.checkStatus()
那之后（我什至在函数上用super（）替换了self，但仍然无法正常工作）为了修复它，我选择不使用父类，而是像两个不同的类一样创建它们。这解决了缺少属性rect的问题，但是当我尝试生成它们（在外星人死亡后）时，.add（）打印了此错误：
文件“ / home / marios / Documents / Programming-TEI / Python_Spyder / Graphics / Game / Star Guardian / Star_Guardian.py”，行1210，在game_Loop中 statusDrop = StatusDrops（display_width，display_height，（private.rect.x +（private.width / 2）），（private.rect.y +（private.height / 2）））
init 中的文件“ /usr/local/lib/python3.6/dist-packages/pygame/sprite.py”，第124行 self.add（* groups）
添加文件“ /usr/local/lib/python3.6/dist-packages/pygame/sprite.py”，第142行 self.add（* group）
TypeError：*之后的add（）参数必须是可迭代的，而不是int
这是rect错误修复的新Status类
class StatusDrops(pygame.sprite.Sprite):
def _init__(self, dw, dh, x, y):
super().__init__()
self.display_width = dw
self.display_height = dh
self.posx = x
self.posy = y
self.speedx = 3
self.speedy = 5
self.pickedUp = 0
self.type = self.setType()
self.setAttributes(self)
self.rect = self.image.get_rect(center = (self.posx, self.posy))
self.image.set_colorkey(YELLOW)
self.setRotation()
def setType(self):
x = 1#random.randrange(1, 5)
return x
#Set attributes, what kind of status will upgrade(health, stamina, tenacity, nano shell)
def setAttributes(self):
#Hero increase's stamina(max health)
if self.type == 1:
self.image = staminaIcon
self.width = 28
self.height = 23
#Hero heal, max heal income = 30% of stamina
elif self.type == 2:
self.image = healIcon
self.width = 28
self.height = 23
#hero increases resistance to slow and stun(lower duration) up to 30%
elif self.type == 3:
self.image = tenacityIcon
self.width = 28
self.height = 23
#hero increases resistance to incoming damage(armor) up to 50%
elif self.type == 4:
self.image = nanoshellIcon
self.width = 28
self.height = 22
self.image = staminaIcon
self.width = 28
self.height = 23
def update(self):
#Movement
self.move()
#Call both sides rotation chances
self.setRotationChance()
self.changeRotation()
#Check drop status
self.checkStatus()
#Set Rotation
def setRotation(self):
self.rotationx = self.rotationy = random.randrange(-1, 1)
if self.rotationx == 0:
self.setRotation()
#Set both side's rotation chance
def setRotationChance(self):
self.rotationxChance = random.randrange(1, 151)
self.rotationyChance = random.randrange(1, 151)
#Change rotation side
def changeRotation(self):
#Side steps rotation
if self.rotationxChance == 1:
if self.rotationx == 1:
self.rotationx = -1
else:
self.rotationx = 1
#Forward steps rotation
if self.rotationyChance == 1:
if self.rotationy == 1:
self.rotationy = -1
else:
self.rotationy = 1
#Movement
def move(self):
self.rect.x += (self.rotationx * self.speedx)
self.rect.y += (self.rotationy * self.speedy)
这里出现.add（）错误（我对导弹和外星人使用相同的方法生成并起作用）
all_sprites_list = pygame.sprite.Group()
status_drops_list = pygame.sprite.Group()
statusDrop = StatusDrops(display_width, display_height, (private.rect.x + (private.width / 2)), (private.rect.y + (private.height / 2)))
all_sprites_list.add(statusDrop)
status_drops_list.add(statusDrop)
谢谢您的时间，如果您再需要我，请问我！
