Handwriting text animation in Unity

A letter from a character that writes itself while the player reads. A signature at the end of a contract. Chalk on a classroom board, a marker note on a map, a calligraphy title that inks in before the logo appears. Handwriting is one of those effects that players notice immediately, and one that most text tools fake with a left-to-right wipe.

Text Studio has real handwriting, and it is honest about when you get it. That distinction matters, so it comes first.

Four kinds of Writing

Writing in Text Studio has explicit levels, from the most authentic to the most general:

When a style asks for more than the text supports, it steps down this ladder instead of failing, and the diagnostics say whether an exact phrase, an authored glyph, an automatic path, an outline or the coverage fallback is in use. The Add Writing section of the manual describes the same levels.

The Writing and Erasing example compares ink coverage, authored strokes, marker and chalk on the same word.

The Writing styles

Text Studio includes nine Writing styles. Five of them come with authored phrases, so you can see true handwriting before making your own:

• Authored Signature: reviewed centerline strokes, explicit pen lifts, variable pressure and a finishing flourish.
• Calligraphy Pressure: a broad-nib phrase with direction-aware pressure and crisp joins.
• Marker Stroke: rounded, high-coverage marker ribbons.
• Chalk Lettering: rough edges and deterministic grain.
• Stroke to Fill: centerlines that hand over cleanly to the filled letters, for logos, signatures and title reveals.
• Outline Trace: a true contour trace of the letters.
• Clean Ink Reveal: a readable ink reveal that works across scripts and ordinary TMP fonts.
• Caption Line Wipe: a low-motion, line-level reveal for captions, lower thirds and information panels.
• Reverse Erase: a reversible backwrite for corrections, rewinds and deliberate removal.

Each style controls the technique and the stroke texture. You can also set the stroke color, which does not replace the text’s final fill, the drawing direction within each letter, and whether the original letter fades in as its stroke finishes, with Fill After Drawing and Fill Fade Duration.

Set it up

1. Select a text and open its Typewriter section.
2. Enable Writing and choose a Writing Style.
3. Pick an animated reveal mode such as By Letter. Instant shows fully drawn letters.
4. Scrub the preview transport in the Inspector to watch the drawing without entering Play Mode.

Applying a Writing card from the Text Gallery does steps 2 and 3 for you: text without an animated reveal gets a By Letter recipe with Finish Current Unit, so the handwriting draws instead of appearing at once. In code, SetTypewriterWritingStyle does the same.

Because Writing uses the typewriter’s own reveal and hide schedule, everything you know from the typewriter guide applies: waits, speed tags, skip, sounds and events. A pen scratch sound per letter or a page-turn event at the end of the letter is the same setup as for dialogue.

Handwriting inside larger effects

A Writing layer can also sit inside a Composed Effect. It then gets the composition’s range, phase, curve, sequence and spatial controls while still consuming the typewriter’s progress. That is how a title can ink in its first word by hand while the rest of the line fades up, or the signature range at the end of a letter can draw by hand while the body text above it simply fades in.

Authored phrases and your own text

True handwriting is phrase-specific by nature: someone has to decide where each stroke starts and where the pen lifts. The included phrases show what that looks like, and the Writing phrase tools capture the exact shaped text, glyph variations and layout from a selected text while preserving authored paths.

For everything else, including player names and localized lines, the automatic pen path draws the letters from the font outline. It looks like drawing rather than one person’s hand, and the diagnostics never pretend otherwise. If the font’s license does not allow embedding its outlines, choose Use existing data only in the Runtime Preparation settings; Text Studio then keeps to data you already have instead of preparing new outlines.

Performance on phones and headsets

Writing used to cause a hitch the first time a new text was drawn, while the pen paths were prepared. Text Studio 1.4 made that first-use preparation about four times faster with fewer allocations, round-join styles now use about two thirds less geometry without changing their finished strokes, and player glyph fills match the Editor. The Writing and Erasing example uses its bundled, prepared Kalam handwriting data, so it never prepares new data in your project.

Writing in 3D

The same Writing styles drive Text Studio 3D, where the stroke can become a raised, volumetric line on extruded letters. The Writing setup and the typewriter timing stay the same.

Export it for a trailer

A drawing effect is easiest to judge in motion. The export guide shows how to save an effect preview as an MP4 or a transparent GIF straight from the Inspector, which is also a quick way to send a handwriting test to an art director.
