从边缘生长¶

限定名称: manim.animation.growing.GrowFromEdge

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

基础：GrowFromPoint

通过从其边界框的一个边缘生长来引入一个Mobject。

Parameters:

mobject (Mobject) – 要引入的mobjects。
edge (np.ndarray) – 寻找mobject边界框边缘的方向。
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。

示例

示例：GrowFromEdgeExample ¶

from manim import *

class GrowFromEdgeExample(Scene):
    def construct(self):
        squares = [Square() for _ in range(4)]
        VGroup(*squares).set_x(0).arrange(buff=1)
        self.play(GrowFromEdge(squares[0], DOWN))
        self.play(GrowFromEdge(squares[1], RIGHT))
        self.play(GrowFromEdge(squares[2], UR))
        self.play(GrowFromEdge(squares[3], UP, point_color=RED))
