Mobject

The defined coordinate functions for ~~Mobject~~ in mobject.py

def get_coord(self, dim, direction=ORIGIN)
def get_x(self, direction=ORIGIN)
def get_y(self, direction=ORIGIN)
def get_z(self, direction=ORIGIN)
def get_z_index_reference_point(self)

Coordinate

def get_coord(self, dim, direction=ORIGIN)

~~get_coord~~ is used to get the coordinate of a ~~Mobject~~ with respect to the specified dim parameter, dim, according to the specified direction parameter, direction.

def get_x(self, direction=ORIGIN)

~~get_x~~ is used to get the x-coordinate of a ~~Mobject~~.

def get_y(self, direction=ORIGIN)

~~get_y~~ is used to get the y-coordinate of a ~~Mobject~~.

def get_z(self, direction=ORIGIN)

~~get_z~~ is used to get the z-coordinate of a ~~Mobject~~.

def get_z_index_reference_point(self)

~~get_z_index_reference_point~~ is used to get the z-index reference point of a ~~Mobject~~
