## Quick Start

### Installation

```bash
# npm
npm install @wia/metaverse

# yarn
yarn add @wia/metaverse

# pnpm
pnpm add @wia/metaverse
```

### Basic Usage

```typescript
import { MetaverseWorld, AssetManagerImpl } from '@wia/metaverse';

// Initialize metaverse world
const world = new MetaverseWorld({
  apiKey: 'your-api-key',
  worldId: 'educational-campus',
  name: 'Educational Campus',
  region: 'us-west-1',
  maxUsers: 10000
});

// Create virtual space
const campus = await world.createSpace({
  name: 'Main Campus',
  type: 'educational',
  size: { x: 1000, y: 50, z: 1000 },
  terrain: 'grass',
  skybox: 'day-clear',
  physics: {
    gravity: 9.81,
    collisions: true
  }
});

// Spawn user avatar
const user = await world.spawnAvatar({
  userId: 'user_123',
  avatarUrl: 'https://myavatar.vrm',
  position: { x: 0, y: 0, z: 0 },
  rotation: { x: 0, y: 0, z: 0, w: 1 },
  metadata: {
    name: 'Sarah Chen',
    reputation: 950
  }
});

// Create portal to another world
await world.createPortal({
  destination: 'wia://science-lab',
  position: { x: 100, y: 0, z: 100 },
  appearance: 'futuristic-gate',
  bidirectional: true
});

// Listen for events
world.on('user:joined', (user) => {
  console.log(`${user.name} joined the world`);
});

world.on('asset:traded', (trade) => {
  console.log(`${trade.asset} sold for ${trade.price} ${trade.currency}`);
});
```

### Digital Asset Management

```typescript
import { AssetManagerImpl } from '@wia/metaverse';

const assetManager = new AssetManagerImpl({
  blockchain: 'ethereum',
  nftStandard: 'ERC-721',
  marketplace: {
    enabled: true,
    royaltyPercentage: 5,
    currency: ['ETH', 'MATIC', 'USDC']
  }
});

// Create NFT asset
const trophy = await assetManager.createAsset({
  name: 'Golden Trophy',
  type: 'collectible',
  modelUrl: 'https://assets.example.com/trophy.glb',
  rarity: 'legendary',
  metadata: {
    creator: 'user_456',
    description: 'Championship trophy'
  }
});

// Transfer asset
await assetManager.transferAsset({
  assetId: trophy.assetId,
  from: 'system',
  to: 'user_123',
  reason: 'quiz_winner'
});
```
