This skill provides a comprehensive text rendering solution for PixiJS v8, covering various text types like Text, BitmapText, HTMLText, and SplitText. It enables developers to choose the most suitable text rendering method based on performance, styling, and animation requirements. This allows for efficient display of high-quality, dynamic, or interactive text content in games, significantly enhancing the user experience and optimizing rendering performance.

Before / After Comparison

1
Before

Before this skill, developers often struggled with balancing text quality and performance in PixiJS, leading to extensive manual optimization efforts or custom implementations for dynamic text, which consumed valuable development time.

After

This skill provides pre-optimized text rendering solutions, allowing developers to quickly select and implement high-performance, high-fidelity, or animatable text effects based on specific needs, significantly reducing development time and improving application performance.

SKILL.md

PixiJS has five text-rendering classes that cover different trade-offs between styling, performance, and animation. Text renders to a canvas for full CSS-style fidelity. BitmapText reads from a pre-generated atlas for cheap updates. HTMLText renders an HTML fragment via SVG <foreignObject> for rich markup. SplitText and SplitBitmapText wrap the first two classes and expose per-character, per-word, and per-line containers for animation.

Assumes familiarity with pixijs-scene-core-concepts. All text classes are leaf nodes; they cannot have children. Wrap multiple text instances in a Container to group them.

Quick Start

const text = new Text({
  text: "Hello PixiJS",
  style: {
    fontFamily: "Arial",
    fontSize: 36,
    fill: 0xffffff,
    stroke: { color: 0x4a1850, width: 5 },
    dropShadow: { color: 0x000000, blur: 4, distance: 6 },
  },
});

text.anchor.set(0.5);
text.x = app.screen.width / 2;
text.y = 40;

app.stage.addChild(text);

All text classes use options-object constructors; positional (string, style) from v7 is not supported.

Variants

VariantUse whenTrade-offsReference
TextHigh-quality static or infrequent-update labelsExpensive to update (canvas re-draw + GPU upload)references/text.md
BitmapTextScores, timers, gameplay labels, anything that changes every frameLimited styling; fixed glyph atlas; requires MSDF for crisp scalingreferences/bitmap-text.md
HTMLTextRich formatted text, mixed styles, real HTML tagsAsync rendering (one frame delay); similar update cost to Textreferences/html-text.md
SplitTextPer-character animation with rich stylingEach char is a full Text; expensive for long stringsreferences/split-text.md
SplitBitmapTextPer-character animation on long strings or dynamic contentInherits BitmapText limitations (glyph atlas, no MSDF-free crispness)references/split-bitmap-text.md

When to use what

  • "I need a styled static label"Text. Use for titles, menus, dialog, error messages. See references/text.md.
  • "I need a score or timer that updates every frame"BitmapText. Updates only reposition quads; no canvas re-draw. See references/bitmap-text.md.
  • "I need mixed formatting with <b>, <i>, <br>"HTMLText. Real HTML/CSS rendering via SVG. See references/html-text.md.
  • "I need inline colored tags like <red>Warning:</red>"Text or HTMLText with tagStyles. Both support it.
  • "I need to animate each character individually"SplitText for short strings, SplitBitmapText for long strings or many instances. See references/split-text.md / references/split-bitmap-text.md.
  • "I need CJK / Arabic / emoji-heavy text"Text or HTMLText. BitmapText fails because the glyph set is too large for a single atlas.
  • "I need a custom font" → Load via Assets.load({ src: 'font.woff2', data: { family: 'MyFont' } }) first, then set style.fontFamily: 'MyFont'. Works for Text and HTMLText.

Update cost comparison

Changing .textHighVery lowHighVery high (N text re-renders)Low (N quad repositions)
Changing .styleHighMediumHighVery highMedium

Rotating / scalingFreeFreeFreeFreeFree

"Free" = normal Container transform cost. "High" = new canvas draw + GPU upload. "Very low" = quad reposition only. Update strings that change per-frame only on BitmapText or SplitBitmapText.

Quick concepts

  • Options-object constructors. Every v8 text class uses new Text({ text, style, ... }). The v7 (string, style) form is removed.
  • tagStyles. Text and HTMLText support per-tag styling via style.tagStyles. Tags are only parsed when tagStyles has entries; otherwise < is treated literally.
  • BitmapFont.install. Pre-generates an atlas before you create any BitmapText. Without install, the first BitmapText with a new fontFamily generates the atlas lazily.
  • MSDF fonts. Multi-channel Signed Distance Field fonts stay sharp at any size. Generate with external tools (e.g., msdf-bmfont), load via Assets.load('font.fnt'). Requires import 'pixi.js/text-bitmap' in custom builds.

Common Mistakes

[HIGH] Updating Text.text every frame

Wrong:

app.ticker.add(() => {
  scoreText.text = `Score: ${score}`;
});

Correct:

const scoreText = new BitmapText({ text: "Score: 0", style });
app.ticker.add(() => {
  scoreText.text = `Score: ${score}`;
});

Every Text update re-rasterizes the whole string. Use BitmapText for any value that changes per-frame.

[HIGH] Positional constructor args

Wrong:

const text = new Text("Hello", { fontSize: 24 });

Correct:

const text = new Text({ text: "Hello", style: { fontSize: 24 } });

v8 removed the (string, style) form. All text classes use options objects.

[HIGH] Not importing pixi.js/text-bitmap in custom builds

Under skipExtensionImports: true or aggressive tree-shaking, Assets.load('font.fnt') silently returns raw data unless you add import 'pixi.js/text-bitmap'. The standard import { ... } from 'pixi.js' bundle includes the extension.

[MEDIUM] Adding children to a text instance

Every text class sets allowChildren = false. Wrap in a Container to group text with other content.
