I have a class called Magic as well as a class called Player. In the player class there is a variable called self.direction which is a pygame.math.Vector2() which I update in my input function. However when I create the Magic class in the input function in the Player class I give it the self.direction variable as the direction, I intended to have the direction be the direction when the Magic class was created and not change. But when I run my code the direction constantly seems to updating itself to my Player class self.direction even when it isn’t supposed to.
Below is the code：

class Magic(pygame.sprite.Sprite):

    def __init__(self,pos,groups,dir):
        
        super().__init__(groups)
        self.image = pygame.image.load('rock.png').convert_alpha()
        self.rect = self.image.get_rect(topleft = pos)
        self.direction = dir
        print("i have been called")
    def move(self):
        
        self.rect.center  += self.direction
        print(self.rect.center)
        #print(self.direction)                                                                                                                                                                                                                                                                                                         
    def update(self):
        self.move()


class Player(pygame.sprite.Sprite):
    def __init__(self,pos,groups,obstacles_sprites,visible_sprites):
        super().__init__(groups)
        global plr
        self.image = pygame.image.load('player.png').convert_alpha()
        self.rect = self.image.get_rect(topleft = pos) 
        self.direction = pygame.math.Vector2()
        self.obstacle_sprites = obstacles_sprites
        self.visible_sprites = visible_sprites
        plr = self.image.get_rect()
    def input(self):
        
        keys = pygame.key.get_pressed()
        if keys[pygame.K_UP]:
            self.direction.y = -1   
            
        elif keys[pygame.K_DOWN]:
            self.direction.y = 1
        else:
            self.direction.y = 0 
        if keys[pygame.K_RIGHT]:
            self.direction.x = 1
            self.collision("Horizontal")
        elif keys[pygame.K_LEFT]:
            self.direction.x = -1
        else:
