从无到有旋转进入

限定名称: manim.animation.growing.SpinInFromNothing

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

基础：GrowFromCenter

介绍一个Mobject从中心旋转并增长。

Parameters:

  • mobject (Mobject) – 要引入的mobjects。

  • angle (float) – 物体在达到其完整大小之前的旋转量。例如，2*PI 表示物体在被完全引入之前会进行一次完整的旋转。

  • point_color (str) – 物体在增长到其完整大小之前的初始颜色。留空以匹配物体的颜色。

from manim import *

class SpinInFromNothingExample(Scene):
    def construct(self):
        squares = [Square() for _ in range(3)]
        VGroup(*squares).set_x(0).arrange(buff=2)
        self.play(SpinInFromNothing(squares[0]))
        self.play(SpinInFromNothing(squares[1], angle=2 * PI))
        self.play(SpinInFromNothing(squares[2], point_color=RED))
