使用前

用户在 PixiJS 中处理不同类型的图像(如静态图、动画、UI 面板、重复背景)时,需要手动编写大量渲染逻辑或集成多个库,导致开发效率低下且代码难以维护。

使用后

此技能提供统一且优化的 Sprite 类,简化了 PixiJS 图像渲染过程,显著减少了开发时间,并确保了视觉内容的一致性和高性能。

SKILL.md

PixiJS has three sprite classes for different drawing tasks. Sprite is the default image-drawing leaf; NineSliceSprite is a resizable UI-panel variant that preserves corner art; TilingSprite repeats a texture across an area. The AnimatedSprite subclass of Sprite cycles through texture frames for frame-based animation.

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

Quick Start

const texture = await Assets.load("bunny.png");

const sprite = new Sprite({
  texture,
  anchor: 0.5,
  tint: 0xff8888,
});
sprite.x = app.screen.width / 2;
sprite.y = app.screen.height / 2;

app.stage.addChild(sprite);

Position is set after construction because app.screen.width / 2 depends on the live renderer size. Literal positions can go directly in the options object via x/y (inherited from Container).

Variants

AnimatedSpriteFrame-based animation from a texture array or spritesheetPre-rendered frames only; no tweeningreferences/animated-sprite.md
NineSliceSpriteResizable UI panels, buttons, dialog framesBorder width is fixed; center stretchesreferences/nineslice-sprite.md
TilingSpriteScrolling backgrounds, parallax, repeating patternsSingle texture repeated; tilePosition scrollsreferences/tiling-sprite.md

AnimatedSprite is a subclass of Sprite; all Sprite properties (anchor, tint, position) apply.

Each variant's constructor options are documented in its sub-reference file (references/{variant}.md). All variants also accept the Container options (position, scale, tint, label, filters, zIndex, etc.) — see skills/pixijs-scene-core-concepts/references/constructor-options.md.

When to use what

  • "I want to draw a single image at a position"Sprite. The default choice for 90% of 2D game and app content.
  • "I want to animate a character through a series of frames"AnimatedSprite. Load a spritesheet via Assets and pass sheet.animations['walk']. See references/animated-sprite.md.
  • "I want a UI button/panel that resizes without stretching the borders"NineSliceSprite. Set border widths, then set width/height. See references/nineslice-sprite.md.
  • "I want a scrolling repeating background"TilingSprite. Animate tilePosition to scroll. See references/tiling-sprite.md.
  • "I want thousands of identical sprites" → Use ParticleContainer with Particle instances (see pixijs-scene-particle-container), not plain sprites.
  • "I want to draw shapes or paths" → Use Graphics (see pixijs-scene-graphics), not a sprite.

Quick concepts

Anchor vs pivot

Sprite.anchor is normalized [0, 1] and shifts only the texture draw origin; no position offset. Container.pivot is pixel-space and shifts both the transform origin and the visual position. For centering a sprite, always use anchor.set(0.5).

Loading before creating

Sprite.from(id) only reads the Assets cache; it does not fetch. Always await Assets.load(...) first, or pass the returned Texture directly to new Sprite(texture).

Dynamic textures

Once a texture is loaded, modifying its frame or swapping its source does not automatically notify sprites. Set texture.dynamic = true once, or call sprite['onViewUpdate']() manually after changes.

Common Mistakes

[HIGH] Using Texture.from(url) to load

Wrong:

const texture = Texture.from("https://example.com/image.png");

Correct:

const texture = await Assets.load("https://example.com/image.png");

Texture.from() only reads the cache in v8. Use Assets.load() first; its return value is the texture.

[HIGH] Confusing anchor and pivot

Wrong:

sprite.pivot.set(sprite.width / 2, sprite.height / 2);

Correct:

sprite.anchor.set(0.5);

anchor shifts only the draw origin. pivot shifts the transform origin AND the visual position, causing the sprite to move unexpectedly.

[HIGH] Old NineSlicePlane name

NineSlicePlane was renamed to NineSliceSprite in v8 and switched to an options-object constructor: new NineSliceSprite({ texture, leftWidth, topHeight, rightWidth, bottomHeight }).

[MEDIUM] Adding children to a sprite

Sprite, NineSliceSprite, and TilingSprite all set allowChildren = false. Wrap in a Container to group sprites with other content.
