How do I fix TypeError: __init__() missing 1 required positional argument: 'y'

Question

I'm currently trying to set up hitboxes for my characters but I can't seem to get rid of this error.

class Player(pygame.sprite.Sprite):
    def __init__(self, x, y):
        self.x = x
        self.y = y
        pygame.sprite.Sprite.__init__(self)
        self.image = IronMan
        self.rect = self.image.get_rect()
        self.rect.y = 475
        self.direction = 1
        self.hitbox = (self.x + 20, self.y + 11, 28, 60)

    def draw(self, win):
        self.hitbox = (self.x + 20, self.y + 11, 28, 60)
        pygame.draw.rect(win, (255, 0, 0), self.hitbox, 2)
                       

When the code is ran Im faced with

TypeError: __init__() missing 1 required positional argument: 'y'

Answer 1

Looks like you didn't provide sufficient parameters when you created an instance of the class. There are 2 options to fix it.

1. Provide sufficient parameters when creating instance.

Example:

Mark = Player() # Error
Cindy = Player(1) # Error
James = Player(1, 2) # Good!

Since you specified _ init _ method to take 2 arguments, you must provide 2 arguments when calling it.

2. Simply set a default value for the arguments. You can do this by using '=' sign.

Example:

def __init__(self, x=0, y=0):
    #blabla

Now, _ init _ method will automatically initialize the arguments to 0, if it's not provided manually.

Mark = Player() # Mark.x=0, Mark.y=0
Cindy = Player(1) # Cindy.x=1, Cindy.y=0
James = Player(1, 2) # James.x=1, James.y=2
