限定名称: manim.animation.transform.ReplacementTransform

class ReplacementTransform(mobject=None, *args, use_override=True, **kwargs)

基础类：Transform

将一个mobject替换并变形为目标mobject。

Parameters:

• mobject (Mobject) – 起始的 Mobject。

• target_mobject (Mobject) – 目标 Mobject。

• kwargs – 传递给Transform的进一步关键字参数。
