LaggedStartMap#

Qualified name: manim.animation.composition.LaggedStartMap

class LaggedStartMap(mobject=None, *args, use_override=True, **kwargs)[source]#

Bases: LaggedStart

Plays a series of Animation while mapping a function to submobjects.

Parameters:

  • AnimationClass (Callable[..., Animation]) – Animation to apply to mobject.

  • mobject (Mobject) – Mobject whose submobjects the animation, and optionally the function, are to be applied.

  • arg_creator (Callable[[Mobject], str]) – Function which will be applied to Mobject.

  • run_time (float) – The duration of the animation in seconds.

Examples

Example: LaggedStartMapExample 

from manim import *

class LaggedStartMapExample(Scene):
    def construct(self):
        title = Tex("LaggedStartMap").to_edge(UP, buff=LARGE_BUFF)

            *[Dot(radius=0.16) for _ in range(35)]
            ).arrange_in_grid(rows=5, cols=7, buff=MED_LARGE_BUFF)
        self.add(dots, title)

        # Animate yellow ripple effect
        for mob in dots, title:
