Shifting N objects with Manim at the same time in different directions

Question

I have a list of dots of variable random length and I want to be able to apply a transform (shift in this case) to these objects with independence but at the same time.

list = [Dot(), Dot() ...] # Variable length

I am using the Manim Library by https://github.com/3b1b/manim by 3blue1brown. As a note, other related posts don't solve my problem as they only work with a fix number of objects (dots).

Answer 1

The following code from this reddit post, used as an example, solves the problem:

import numpy as np

class DotsMoving(Scene):
    def construct(self):
        dots = [Dot() for i in range(5)]
        directions = [np.random.randn(3) for dot in dots]
        self.add(*dots) # It isn't absolutely necessary
        animations = [ApplyMethod(dot.shift,direction) for dot,direction in zip(dots,directions)]
        self.play(*animations) # * -> unpacks the list animations
