Positioning Functions

def center(self)

~~center~~ is used to shift a ~~Mobject~~ with respect to the negative sense of the center of the ~~Mobject~~.

def align_on_border(self, direction, buff=DEFAULT_MOBJECT_TO_EDGE_BUFFER)

~~align_on_border~~ is used to align the border of a ~~Mobject~~ with respect to the specified direction parameter, direction, according to the specified parameters.

def to_corner(self, corner=LEFT + DOWN, buff=DEFAULT_MOBJECT_TO_EDGE_BUFFER)

~~to_corner~~ is used to align the corner of a ~~Mobject~~ with respect to the specified corner parameter, corner, according to the specified parameters.

def to_edge(self, edge=LEFT, buff=DEFAULT_MOBJECT_TO_EDGE_BUFFER)

~~to_edge~~ is used to align the edge of a ~~Mobject~~ with respect to the specified edge parameter, edge, according to the specified parameters.

def next_to(self, mobject_or_point, direction=RIGHT, buff=DEFAULT_MOBJECT_TO_MOBJECT_BUFFER, aligned_edge=ORIGIN, submobject_to_align=None, index_of_submobject_to_align=None, coor_mask=np.array([1, 1, 1]))

~~next_to~~ is used to move a ~~Mobject~~ with respect to the specified mobject parameter, mobject_or_point, according to the specified parameters.

def shift_onto_screen(self, **kwargs)

~~shift_onto_screen~~ is used to shift a ~~Mobject~~ onto screen from off screen.

def shift(self, *vectors)

~~shift~~ is used to shift a ~~Mobject~~ with respect to the specified vectors parameter, *vectors, according to the corresponding property of the specified parameters.

def set_coord(self, value, dim, direction=ORIGIN)

~~set_coord~~ is used to set the coordinate of a ~~Mobject~~ with respect to the specified value parameter, value , of specified dimension parameter, dim, according to the corresponding property of the specified parameters.

def set_x(self, x, direction=ORIGIN)

~~set_x~~ is used to set the x dimension of a ~~Mobject~~ with respect to the specified x parameter, x, according to the corresponding property of the specified parameters.

def set_y(self, y, direction=ORIGIN)

~~set_y~~ is used to set the y dimension of a ~~Mobject~~ with respect to the specified y parameter, y, according to the corresponding property of the specified parameters.

def set_z(self, z, direction=ORIGIN)

~~set_z~~ is used to set the z dimension of a ~~Mobject~~ with respect to the specified z parameter, z, according to the corresponding property of the specified parameters.

def move_to(self, point_or_mobject, aligned_edge=ORIGIN, coor_mask=np.array([1, 1, 1]))

~~move_to~~ is used to move a ~~Mobject~~ with respect to the specified point_or_mobject parameter, mobject_or_point, according to the specified parameters.
