## Quick Start

```bash
npm install @joshtol/emotive-engine
```

### 3D Mode (WebGL)

```javascript
import { EmotiveMascot3D } from '@joshtol/emotive-engine/3d';

const mascot = new EmotiveMascot3D({
    coreGeometry: 'crystal',
    assetBasePath: '/assets', // self-hosted assets (see below)
});

mascot.init(document.getElementById('container'));
mascot.start();

mascot.setEmotion('joy');
mascot.express('bounce');
mascot.morphTo('heart');
mascot.feel('happy, bouncing'); // Natural language control
```

3D mode requires Three.js: `npm install three`

### 2D Mode (Canvas)

```javascript
import { EmotiveMascot } from '@joshtol/emotive-engine';

const mascot = new EmotiveMascot();
await mascot.init(document.getElementById('container'));
mascot.start();
mascot.feel('happy, bouncing');
```

2D mode has no dependencies and requires no external assets.

## 3D Assets

The npm package ships **JavaScript only**. GLB models, textures, and HDRI maps
must be self-hosted (~24 MB). They live in `assets/` in this repository.

```javascript
new EmotiveMascot3D({
    assetBasePath: '/assets', // wherever you host the assets folder
});
```

| Hosting Option        | `assetBasePath`                                     |
| --------------------- | --------------------------------------------------- |
| **Copy to `public/`** | `'/assets'`                                         |

| **GitHub Pages**      | `'https://joshtol.github.io/emotive-engine/assets'` |

```
<assetBasePath>/
├── models/Elements/   # GLB models for elemental effects
├── textures/          # Crystal, Moon, Sun textures
└── hdri/              # Environment maps (optional)
