Qualified name: manim.animation.transform\_matching\_parts.TransformMatchingTex

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

Bases: TransformMatchingAbstractBase

Examples

Example: MatchingEquationParts

from manim import *

class MatchingEquationParts(Scene):
    def construct(self):
        variables = VGroup(MathTex("a"), MathTex("b"), MathTex("c")).arrange_submobjects().shift(UP)

        eq1 = MathTex("{{x}}^2", "+", "{{y}}^2", "=", "{{z}}^2")
        eq2 = MathTex("{{a}}^2", "+", "{{b}}^2", "=", "{{c}}^2")
        eq3 = MathTex("{{a}}^2", "=", "{{c}}^2", "-", "{{b}}^2")

        self.add(eq1)
        self.wait(0.5)
        self.play(TransformMatchingTex(Group(eq1, variables), eq2))
        self.wait(0.5)
        self.play(TransformMatchingTex(eq2, eq3))
