Manim's method 10

Overview

I checked manim's method. I tried using add_updater.

Sample code

from manimlib.imports import *

class test(Scene):
	def construct(self):
		self.t_offset = 0
		dot = Dot()
		rate = 0.25
		orbit = Circle()
		def around_circle(mob, dt):
			self.t_offset += (dt * rate)
			mob.move_to(orbit.point_from_proportion(self.t_offset % 1))
		dot.add_updater(around_circle)
		self.add(dot)
		self.wait(5)
