@haiyue/extensions

Optional runtime capabilities for @haiyue/engine.

Stable entrypoints

• @haiyue/extensions/gltf — glTF loading, runtime components, compatibility reports, materials, and the engine plugin.
• @haiyue/extensions/animation3d — source-independent 3D clips, mixers, pose buffers, layers, masks, events, state machines, and the HYA adapter.
• @haiyue/extensions/gltf-animation3d — adapts glTF clips to the source-independent Animation3D runtime.
• @haiyue/extensions/animation — HYA Animation2D components, systems, loading, rendering, and state-machine integration.
• @haiyue/extensions/hya-state-machine — the focused HYA 2D state-machine runtime.
• @haiyue/extensions/spine — Spine component, render system, plugin, and the stable worker interface seam.
• @haiyue/extensions/tilemap — Tilemap2D component, render system, and plugin.
• @haiyue/extensions/canvas-text — Canvas text component and render system.
• @haiyue/extensions/tween — Tween2D component and update system.
• @haiyue/extensions/grid — Grid2D component contract.

import { HaiyueEngine } from '@haiyue/engine';
import { createGltfPlugin } from '@haiyue/extensions/gltf';
import { Animation3DMixer } from '@haiyue/extensions/animation3d';
import { createGltfAnimation3DRuntime } from '@haiyue/extensions/gltf-animation3d';

const engine = new HaiyueEngine({ canvas: '#app' });
engine.installPlugin(createGltfPlugin());

The package root remains a minimal experimental authoring base. Worker transport and low-level parsing are explicitly available from @haiyue/extensions/experimental/gltf-worker and @haiyue/extensions/experimental/spine-worker; they may change without stable-API compatibility guarantees.

WebGPU is required by the runtime; there is no WebGL fallback.
