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!!!
