another weird situation with pygame I guess. I want to creat a drop class which will be the parent class of statusdrops(health,armor etc...) and weapondrops(increase damage, switch weapon etc...). I need that because the two children will have almost the same functions but for some reason I failed with the inheritance, I checked the python documentation and still not sure what is going on.

Here is the first attempt using the 3 classes that gave me this error: 'StatusDrops' object has no attribute 'rect'. But I used the exact same method for my aliens and worked fine so far

Drop parent class

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 child class (I didn't proceed to the weaponDrop because of the error)

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()

After that(I even replace the self with super() on the functions but still didn't work) in order to fix it I chose not to use a parent class and just create them like 2 different classes. That fixed the problem of the missing attribute rect but when I tried to spawn them (after the alien died) the .add() printed this error:

File "/home/marios/Documents/Programming - TEI/Python_Spyder/Graphics/Game/Star Guardian/Star_Guardian.py", line 1210, in game_Loop
statusDrop = StatusDrops(display_width, display_height, (private.rect.x + (private.width / 2)), (private.rect.y + (private.height / 2)))

File "/usr/local/lib/python3.6/dist-packages/pygame/sprite.py", line 124, in init
self.add(*groups)

File "/usr/local/lib/python3.6/dist-packages/pygame/sprite.py", line 142, in add
self.add(*group)

TypeError: add() argument after * must be an iterable, not int

This is the new Status class that the rect error fixed

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)

And here the .add() error appears(I used the same method for the missiles and alien spawn and worked)

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)

Thank you for your time, if you need anymore just ask me!!!
