Mobject

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

def wag(self, direction=RIGHT, axis=DOWN, wag_factor=1.0)
def pose_at_angle(self, **kwargs)
def put_start_and_end_on(self, start, end)

Distorting

def wag(self, direction=RIGHT, axis=DOWN, wag_factor=1.0)

~~def wag~~ is used to deform a ~~Mobject~~ with respect to the specified axis parameter, default axis is ~~DOWN~~, in the specified direction parametet, default direction is ~~RIGHT~~, according to the specified parameters.

def pose_at_angle(self, **kwargs)

~~def pose_at_angle~~ is used to rotate a ~~Mobject~~ about the center of the ~~Mobject~~, with respect to the specified axis parameter, default axis is ~~RIGHT + UP~~, with the specified angle parametet, default angle is ~~TAU / 14~~, according to the specified parameters.

def put_start_and_end_on(self, start, end)

~~def put_start_and_end_on~~ is used to distort an open ~~Mobject~~ by puting the start and end on the specified start parameter, start, and the specified end parameter, end, according to the specified parameters.
