class Barril:
    '''
    The class representing a barrel
    Attributes:
        x1 - The positon in the x axis -> xpos - gets the x1 value
        y1 - The positon in the y axis -> ypos - gets the y1 value
        w - The width
        h - The heigth
        p . number of image set
        u - coordinates in x of the frame in the image set
        v - cordinates in y of the frame in the image set
        relentization - Quantity of frames needed in order to update a sprite
        
    Methods:
        update - updates the object
        stairs_check - checks if there are stairs
        fall - It is in charge of the position in y1
        getFrame - returns the specifications needed in order to draw the sprite in the main porgram
