Text and math¶
The film's code
import manimgx as m
class TextAndMathHero(m.Scene):
def construct(self) -> None:
title = m.Text("The Pythagorean theorem", font_size=56)
formula = m.MathTex("a^2", "+", "b^2", "=", "c^2", font_size=80)
formula[2].set_color(m.YELLOW)
number = m.DecimalNumber(
3.14159, num_decimal_places=4, font_size=56, color=m.BLUE
)
lines = m.VGroup(title, formula, number).arrange(m.DOWN, buff=0.7)

self.play(m.Write(formula))

manimgx sets text and formulas itself, with Typst and the fonts that come with it: you install no LaTeX and no fonts, and a text looks the same on every computer. A text is a mobject made of its glyphs, so it moves, scales, colors and animates as any shape does.
Write words with Text, a formula in LaTeX with MathTex, words with formulas in them with Tex, and Typst markup with Typst. A number that changes is a DecimalNumber.
