+# Network System
+
+`@esengine/network` provides a TSRPC-based client-server network synchronization solution for multiplayer games, including entity synchronization, input handling, and state interpolation.
+
+## Overview
+
+The network module consists of three packages:
+
+| Package | Description |
+|---------|-------------|
+| `@esengine/network` | Client-side ECS plugin |
+| `@esengine/network-protocols` | Shared protocol definitions |
+| `@esengine/network-server` | Server-side implementation |
+
+## Installation
+
+```bash
+# Client
+npm install @esengine/network
+
+# Server
+npm install @esengine/network-server
+```
+
+## Quick Start
+
+### Client
+
+```typescript
+import { World } from '@esengine/ecs-framework';
+import {
+    NetworkPlugin,
+    NetworkIdentity,
+    NetworkTransform
+} from '@esengine/network';
+
+// Create World and install network plugin
+const world = new World();
+const networkPlugin = new NetworkPlugin({
+    serverUrl: 'ws://localhost:3000'
+});
+networkPlugin.install(world.services);
+
+// Register prefab factory
+networkPlugin.registerPrefab('player', (netId, ownerId) => {
+    const entity = world.createEntity(`player_${netId}`);
+    entity.addComponent(new NetworkIdentity(netId, ownerId));
+    entity.addComponent(new NetworkTransform());
+    // Add other components...
+    return entity;
+});
+
+// Connect to server
+await networkPlugin.connect('PlayerName');
+console.log('Connected! Client ID:', networkPlugin.localPlayerId);
+
+// Disconnect
+networkPlugin.disconnect();
+```
+
+### Server
+
+```typescript
+import { GameServer } from '@esengine/network-server';
+
+const server = new GameServer({
+    port: 3000,
+    roomConfig: {
+        maxPlayers: 16,
+        tickRate: 20
+    }
+});
+
+await server.start();
+```
+
+## Core Concepts
+
+### Architecture
+
+```
+Client                              Server
+┌────────────────┐                ┌────────────────┐
+│ NetworkPlugin  │◄──── WS ────► │  GameServer    │
+│ ├─ Service     │                │  ├─ Room       │
+│ ├─ SyncSystem  │                │  └─ Players    │
+│ ├─ SpawnSystem │                └────────────────┘
+│ └─ InputSystem │
+└────────────────┘
+```
+
+### Components
+
+#### NetworkIdentity
+
+Network identity component, required for every networked entity:
+
+```typescript
+class NetworkIdentity extends Component {
+    netId: number;           // Network unique ID
+    ownerId: number;         // Owner client ID
+    bIsLocalPlayer: boolean; // Whether local player
+    bHasAuthority: boolean;  // Whether has control authority
+}
+```
+
+#### NetworkTransform
+
+Network transform component for position and rotation sync:
+
+```typescript
+class NetworkTransform extends Component {
+    position: { x: number; y: number };
+    rotation: number;
+    velocity: { x: number; y: number };
+}
+```
+
+### Systems
+
+#### NetworkSyncSystem
+
+Handles server state synchronization and interpolation:
+
+- Receives server state snapshots
+- Stores states in snapshot buffer
+- Performs interpolation for remote entities
+
+#### NetworkSpawnSystem
+
+Handles network entity spawning and despawning:
+
+- Listens for Spawn/Despawn messages
+- Creates entities using registered prefab factories
+- Manages networked entity lifecycle
+
+#### NetworkInputSystem
+
+Handles local player input sending:
+
+- Collects local player input
+- Sends input to server
+- Supports movement and action inputs
+
+## API Reference
+
+### NetworkPlugin
+
+```typescript
+class NetworkPlugin {
+    constructor(config: INetworkPluginConfig);
+
+    // Install plugin
+    install(services: ServiceContainer): void;
+
+    // Connect to server
+    connect(playerName: string, roomId?: string): Promise<void>;
+
+    // Disconnect
+    disconnect(): void;
+
+    // Register prefab factory
+    registerPrefab(prefab: string, factory: PrefabFactory): void;
+
+    // Properties
+    readonly localPlayerId: number | null;
+    readonly isConnected: boolean;
+}
+```
+
+**Configuration:**
+
+| Property | Type | Required | Description |
+|----------|------|----------|-------------|
+| `serverUrl` | `string` | Yes | WebSocket server URL |
+
+### NetworkService
+
+Network service managing WebSocket connections:
+
+```typescript
+class NetworkService {
+    // Connection state
+    readonly state: ENetworkState;
+    readonly isConnected: boolean;
+    readonly clientId: number | null;
+    readonly roomId: string | null;
+
+    // Connection control
+    connect(serverUrl: string): Promise<void>;
+    disconnect(): void;
+
+    // Join room
+    join(playerName: string, roomId?: string): Promise<ResJoin>;
+
+    // Send input
+    sendInput(input: IPlayerInput): void;
+
+    // Event callbacks
+    setCallbacks(callbacks: Partial<INetworkCallbacks>): void;
+}
+```
+
+**Network state enum:**
+
+```typescript
+enum ENetworkState {
+    Disconnected = 'disconnected',
+    Connecting = 'connecting',
+    Connected = 'connected',
+    Joining = 'joining',
+    Joined = 'joined'
+}
+```
+
+**Callbacks interface:**
+
+```typescript
+interface INetworkCallbacks {
+    onConnected?: () => void;
+    onDisconnected?: () => void;
+    onJoined?: (clientId: number, roomId: string) => void;
+    onSync?: (msg: MsgSync) => void;
+    onSpawn?: (msg: MsgSpawn) => void;
+    onDespawn?: (msg: MsgDespawn) => void;
+}
+```
+
+### Prefab Factory
+
+```typescript
+type PrefabFactory = (netId: number, ownerId: number) => Entity;
+```
+
+Register prefab factories for network entity creation:
+
+```typescript
+networkPlugin.registerPrefab('enemy', (netId, ownerId) => {
+    const entity = world.createEntity(`enemy_${netId}`);
+    entity.addComponent(new NetworkIdentity(netId, ownerId));
+    entity.addComponent(new NetworkTransform());
+    entity.addComponent(new EnemyComponent());
+    return entity;
+});
+```
+
+### Input System
+
+#### NetworkInputSystem
+
+```typescript
+class NetworkInputSystem extends EntitySystem {
+    // Add movement input
+    addMoveInput(x: number, y: number): void;
+
+    // Add action input
+    addActionInput(action: string): void;
+
+    // Clear input
+    clearInput(): void;
+}
+```
+
+Usage example:
+
+```typescript
+const inputSystem = world.getSystem(NetworkInputSystem);
+
+// Handle keyboard input
+if (keyboard.isPressed('W')) {
+    inputSystem.addMoveInput(0, 1);
+}
+if (keyboard.isPressed('Space')) {
+    inputSystem.addActionInput('jump');
+}
+```
+
+## State Synchronization
+
+### Snapshot Buffer
+
+Stores server state snapshots for interpolation:
+
+```typescript
+import { createSnapshotBuffer, type IStateSnapshot } from '@esengine/network';
+
+const buffer = createSnapshotBuffer<IStateSnapshot>({
+    maxSnapshots: 30,          // Max snapshots
+    interpolationDelay: 100    // Interpolation delay (ms)
+});
+
+// Add snapshot
+buffer.addSnapshot({
+    time: serverTime,
+    entities: states
+});
+
+// Get interpolated state
+const interpolated = buffer.getInterpolatedState(clientTime);
+```
+
+### Transform Interpolators
+
+#### Linear Interpolator
+
+```typescript
+import { createTransformInterpolator } from '@esengine/network';
+
+const interpolator = createTransformInterpolator();
+
+// Add state
+interpolator.addState(time, { x: 0, y: 0, rotation: 0 });
+
+// Get interpolated result
+const state = interpolator.getInterpolatedState(currentTime);
+```
+
+#### Hermite Interpolator
+
+Uses Hermite splines for smoother interpolation:
+
+```typescript
+import { createHermiteTransformInterpolator } from '@esengine/network';
+
+const interpolator = createHermiteTransformInterpolator({
+    bufferSize: 10
+});
+
+// Add state with velocity
+interpolator.addState(time, {
+    x: 100,
+    y: 200,
+    rotation: 0,
+    vx: 5,
+    vy: 0
+});
+
+// Get smooth interpolated result
+const state = interpolator.getInterpolatedState(currentTime);
+```
+
+### Client Prediction
+
+Implement client-side prediction with server reconciliation:
+
+```typescript
+import { createClientPrediction } from '@esengine/network';
+
+const prediction = createClientPrediction({
+    maxPredictedInputs: 60,
+    reconciliationThreshold: 0.1
+});
+
+// Predict input
+const seq = prediction.predict(inputState, currentState, (state, input) => {
+    // Apply input to state
+    return applyInput(state, input);
+});
+
+// Server reconciliation
+const corrected = prediction.reconcile(
+    serverState,
+    serverSeq,
+    (state, input) => applyInput(state, input)
+);
+```
+
+## Server Side
+
+### GameServer
+
+```typescript
+import { GameServer } from '@esengine/network-server';
+
+const server = new GameServer({
+    port: 3000,
+    roomConfig: {
+        maxPlayers: 16,    // Max players per room
+        tickRate: 20       // Sync rate (Hz)
+    }
+});
+
+// Start server
+await server.start();
+
+// Get room
+const room = server.getOrCreateRoom('room-id');
+
+// Stop server
+await server.stop();
+```
+
+### Room
+
+```typescript
+class Room {
+    readonly id: string;
+    readonly playerCount: number;
+    readonly isFull: boolean;
+
+    // Add player
+    addPlayer(name: string, connection: Connection): IPlayer | null;
+
+    // Remove player
+    removePlayer(clientId: number): void;
+
+    // Get player
+    getPlayer(clientId: number): IPlayer | undefined;
+
+    // Handle input
+    handleInput(clientId: number, input: IPlayerInput): void;
+
+    // Destroy room
+    destroy(): void;
+}
+```
+
+**Player interface:**
+
+```typescript
+interface IPlayer {
+    clientId: number;        // Client ID
+    name: string;            // Player name
+    connection: Connection;  // Connection object
+    netId: number;           // Network entity ID
+}
+```
+
+## Protocol Types
+
+### Message Types
+
+```typescript
+// State sync message
+interface MsgSync {
+    time: number;
+    entities: IEntityState[];
+}
+
+// Entity state
+interface IEntityState {
+    netId: number;
+    pos?: Vec2;
+    rot?: number;
+}
+
+// Spawn message
+interface MsgSpawn {
+    netId: number;
+    ownerId: number;
+    prefab: string;
+    pos: Vec2;
+    rot: number;
+}
+
+// Despawn message
+interface MsgDespawn {
+    netId: number;
+}
+
+// Input message
+interface MsgInput {
+    input: IPlayerInput;
+}
+
+// Player input
+interface IPlayerInput {
+    seq?: number;
+    moveDir?: Vec2;
+    actions?: string[];
+}
+```
+
+### API Types
+
+```typescript
+// Join request
+interface ReqJoin {
+    playerName: string;
+    roomId?: string;
+}
+
+// Join response
+interface ResJoin {
+    clientId: number;
+    roomId: string;
+    playerCount: number;
+}
+```
+
+## Blueprint Nodes
+
+The network module provides blueprint nodes for visual scripting:
+
+- `IsLocalPlayer` - Check if entity is local player
+- `IsServer` - Check if running on server
+- `HasAuthority` - Check if has authority over entity
+- `GetNetworkId` - Get entity's network ID
+- `GetLocalPlayerId` - Get local player ID
+
+## Service Tokens
+
+For dependency injection:
+
+```typescript
+import {
+    NetworkServiceToken,
+    NetworkSyncSystemToken,
+    NetworkSpawnSystemToken,
+    NetworkInputSystemToken
+} from '@esengine/network';
+
+// Get service
+const networkService = services.get(NetworkServiceToken);
+```
+
+## Practical Example
+
+### Complete Multiplayer Client
+
+```typescript
+import { World, EntitySystem, Matcher } from '@esengine/ecs-framework';
+import {
+    NetworkPlugin,
+    NetworkIdentity,
+    NetworkTransform,
+    NetworkInputSystem
+} from '@esengine/network';
+
+// Create game world
+const world = new World();
+
+// Configure network plugin
+const networkPlugin = new NetworkPlugin({
+    serverUrl: 'ws://localhost:3000'
+});
+networkPlugin.install(world.services);
+
+// Register player prefab
+networkPlugin.registerPrefab('player', (netId, ownerId) => {
+    const entity = world.createEntity(`player_${netId}`);
+
+    const identity = new NetworkIdentity(netId, ownerId);
+    entity.addComponent(identity);
+    entity.addComponent(new NetworkTransform());
+
+    // If local player, add input component
+    if (identity.bIsLocalPlayer) {
+        entity.addComponent(new LocalInputComponent());
+    }
+
+    return entity;
+});
+
+// Connect to server
+async function startGame() {
+    try {
+        await networkPlugin.connect('Player1');
+        console.log('Connected! Player ID:', networkPlugin.localPlayerId);
+    } catch (error) {
+        console.error('Connection failed:', error);
+    }
+}
+
+// Game loop
+function gameLoop(deltaTime: number) {
+    world.update(deltaTime);
+}
+
+startGame();
+```
+
+### Handling Input
+
+```typescript
+class LocalInputHandler extends EntitySystem {
+    private _inputSystem: NetworkInputSystem;
+
+    constructor() {
+        super(Matcher.all(NetworkIdentity, LocalInputComponent));
+    }
+
+    protected onAddedToWorld(): void {
+        this._inputSystem = this.world.getSystem(NetworkInputSystem);
+    }
+
+    protected processEntity(entity: Entity, dt: number): void {
+        const identity = entity.getComponent(NetworkIdentity);
+        if (!identity.bIsLocalPlayer) return;
+
+        // Read keyboard input
+        let moveX = 0;
+        let moveY = 0;
+
+        if (keyboard.isPressed('A')) moveX -= 1;
+        if (keyboard.isPressed('D')) moveX += 1;
+        if (keyboard.isPressed('W')) moveY += 1;
+        if (keyboard.isPressed('S')) moveY -= 1;
+
+        if (moveX !== 0 || moveY !== 0) {
+            this._inputSystem.addMoveInput(moveX, moveY);
+        }
+
+        if (keyboard.isJustPressed('Space')) {
+            this._inputSystem.addActionInput('jump');
+        }
+    }
+}
+```
+
+## Best Practices
+
+1. **Set appropriate sync rate**: Choose `tickRate` based on game type, action games typically need 20-60 Hz
+
+2. **Use interpolation delay**: Set appropriate `interpolationDelay` to balance latency and smoothness
+
+3. **Client prediction**: Use client-side prediction for local players to reduce input lag
+
+4. **Prefab management**: Register prefab factories for each networked entity type
+
+5. **Authority checks**: Use `bHasAuthority` to check entity control permissions
+
+6. **Connection state**: Monitor connection state changes, handle reconnection
+
+```typescript
+networkService.setCallbacks({
+    onConnected: () => console.log('Connected'),
+    onDisconnected: () => {
+        console.log('Disconnected');
+        // Handle reconnection logic
+    }
+});
+```

+### NetworkPlugin
+
+```typescript
+class NetworkPlugin {
+    constructor(config: INetworkPluginConfig);
+
+    // 安装插件
+    install(services: ServiceContainer): void;
+
+    // 连接服务器
+    connect(playerName: string, roomId?: string): Promise<void>;
+
+    // 断开连接
+    disconnect(): void;
+
+    // 注册预制体工厂

+
+    // 属性
+    readonly localPlayerId: number | null;
+    readonly isConnected: boolean;
+}
+```
+
+**配置选项：**
+
+| 属性 | 类型 | 必需 | 描述 |
+|------|------|------|------|
+| `serverUrl` | `string` | 是 | WebSocket 服务器地址 |
+
+### NetworkService
+
+网络服务，管理 WebSocket 连接：
+
+```typescript
+class NetworkService {
+    // 连接状态
+    readonly state: ENetworkState;
+    readonly isConnected: boolean;
+    readonly clientId: number | null;
+    readonly roomId: string | null;
+
+    // 连接控制
+    connect(serverUrl: string): Promise<void>;
+    disconnect(): void;
+
+    // 加入房间
+    join(playerName: string, roomId?: string): Promise<ResJoin>;
+
+    // 发送输入
+    sendInput(input: IPlayerInput): void;
+
+    // 事件回调
+    setCallbacks(callbacks: Partial<INetworkCallbacks>): void;
+}
+```
+
+**网络状态枚举：**
+
+```typescript
+enum ENetworkState {
+    Disconnected = 'disconnected',
+    Connecting = 'connecting',
+    Connected = 'connected',
+    Joining = 'joining',
+    Joined = 'joined'
+}
+```
+
+**回调接口：**
+
+```typescript
+interface INetworkCallbacks {
+    onConnected?: () => void;
+    onDisconnected?: () => void;
+    onJoined?: (clientId: number, roomId: string) => void;
+    onSync?: (msg: MsgSync) => void;
+    onSpawn?: (msg: MsgSpawn) => void;
+    onDespawn?: (msg: MsgDespawn) => void;
+}
+```
+
+### 预制体工厂
+
+```typescript
+type PrefabFactory = (netId: number, ownerId: number) => Entity;
+```
+
+注册预制体工厂用于网络实体的创建：
+
+```typescript
+networkPlugin.registerPrefab('enemy', (netId, ownerId) => {
+    const entity = world.createEntity(`enemy_${netId}`);
+    entity.addComponent(new NetworkIdentity(netId, ownerId));
+    entity.addComponent(new NetworkTransform());
+    entity.addComponent(new EnemyComponent());
+    return entity;
+});
+```
+
+### 输入系统
+
+#### NetworkInputSystem
+
+```typescript
+class NetworkInputSystem extends EntitySystem {
+    // 添加移动输入
+    addMoveInput(x: number, y: number): void;
+
+    // 添加动作输入
+    addActionInput(action: string): void;
+
+    // 清除输入
+    clearInput(): void;
+}
+```
+
+使用示例：
+
+```typescript
+const inputSystem = world.getSystem(NetworkInputSystem);
+
+// 处理键盘输入
+if (keyboard.isPressed('W')) {
+    inputSystem.addMoveInput(0, 1);
+}
+if (keyboard.isPressed('Space')) {
+    inputSystem.addActionInput('jump');
+}
+```
+
+## 状态同步
+
+### 快照缓冲区
+
+用于存储服务器状态快照并进行插值：
+
+```typescript
+import { createSnapshotBuffer, type IStateSnapshot } from '@esengine/network';
+
+const buffer = createSnapshotBuffer<IStateSnapshot>({
+    maxSnapshots: 30,          // 最大快照数
+    interpolationDelay: 100    // 插值延迟 (ms)
+});
+
+// 添加快照
+buffer.addSnapshot({
+    time: serverTime,
+    entities: states
+});
+
+// 获取插值状态
+const interpolated = buffer.getInterpolatedState(clientTime);
+```
+
+### 变换插值器
+
+#### 线性插值器
+
+```typescript
+import { createTransformInterpolator } from '@esengine/network';
+
+const interpolator = createTransformInterpolator();
+
+// 添加状态
+interpolator.addState(time, { x: 0, y: 0, rotation: 0 });
+
+// 获取插值结果
+const state = interpolator.getInterpolatedState(currentTime);
+```
+
+#### Hermite 插值器
+
+使用 Hermite 样条实现更平滑的插值：
+
+```typescript
+import { createHermiteTransformInterpolator } from '@esengine/network';
+
+const interpolator = createHermiteTransformInterpolator({
+    bufferSize: 10
+});
+
+// 添加带速度的状态
+interpolator.addState(time, {
+    x: 100,
+    y: 200,
+    rotation: 0,
+    vx: 5,
+    vy: 0
+});
+
+// 获取平滑的插值结果
+const state = interpolator.getInterpolatedState(currentTime);
+```
+
+### 客户端预测
+
+实现客户端预测和服务器校正：
+
+```typescript
+import { createClientPrediction } from '@esengine/network';
+
+const prediction = createClientPrediction({
+    maxPredictedInputs: 60,
+    reconciliationThreshold: 0.1
+});
+
+// 预测输入
+const seq = prediction.predict(inputState, currentState, (state, input) => {
+    // 应用输入到状态
+    return applyInput(state, input);
+});
+
+// 服务器校正
+const corrected = prediction.reconcile(
+    serverState,
+    serverSeq,
+    (state, input) => applyInput(state, input)
+);
+```
+
+## 服务器端
+
+### GameServer
+
+```typescript
+import { GameServer } from '@esengine/network-server';
+
+const server = new GameServer({
+    port: 3000,
+    roomConfig: {
+        maxPlayers: 16,    // 房间最大玩家数
+        tickRate: 20       // 同步频率 (Hz)
+    }
+});
+
+// 启动服务器
+await server.start();
+
+// 获取房间
+const room = server.getOrCreateRoom('room-id');
+
+// 停止服务器
+await server.stop();
+```
+
+### Room
+
+```typescript
+class Room {
+    readonly id: string;
+    readonly playerCount: number;
+    readonly isFull: boolean;
+
+    // 添加玩家
+    addPlayer(name: string, connection: Connection): IPlayer | null;
+
+    // 移除玩家
+    removePlayer(clientId: number): void;
+
+    // 获取玩家
+    getPlayer(clientId: number): IPlayer | undefined;
+
+    // 处理输入
+    handleInput(clientId: number, input: IPlayerInput): void;
+
+    // 销毁房间
+    destroy(): void;
+}
+```
+
+**玩家接口：**
+
+```typescript
+interface IPlayer {
+    clientId: number;    // 客户端 ID
+    name: string;        // 玩家名称
+    connection: Connection;  // 连接对象
+    netId: number;       // 网络实体 ID
+}
+```
+
+## 协议类型
+
+### 消息类型
+
+```typescript
+// 状态同步消息
+interface MsgSync {
+    time: number;
+    entities: IEntityState[];
+}
+
+// 实体状态
+interface IEntityState {
+    netId: number;
+    pos?: Vec2;
+    rot?: number;
+}
+
+// 生成消息
+interface MsgSpawn {
+    netId: number;
+    ownerId: number;
+    prefab: string;
+    pos: Vec2;
+    rot: number;
+}
+
+// 销毁消息
+interface MsgDespawn {
+    netId: number;
+}
+
+// 输入消息
+interface MsgInput {
+    input: IPlayerInput;
+}
+
+// 玩家输入
+interface IPlayerInput {
+    seq?: number;
+    moveDir?: Vec2;
+    actions?: string[];
+}
+```
+
+### API 类型
+
+```typescript
+// 加入请求
+interface ReqJoin {
+    playerName: string;
+    roomId?: string;
+}
+
+// 加入响应
+interface ResJoin {
+    clientId: number;
+    roomId: string;
+    playerCount: number;
+}
+```
+
+## 蓝图节点
+
+网络模块提供了可视化脚本支持的蓝图节点：
+
+- `IsLocalPlayer` - 检查实体是否为本地玩家
+- `IsServer` - 检查是否运行在服务器端
+- `HasAuthority` - 检查是否有权限控制实体
+- `GetNetworkId` - 获取实体的网络 ID
+- `GetLocalPlayerId` - 获取本地玩家 ID
+
+## 服务令牌
+
+用于依赖注入：
+
+```typescript
+import {
+    NetworkServiceToken,
+    NetworkSyncSystemToken,
+    NetworkSpawnSystemToken,
+    NetworkInputSystemToken
+} from '@esengine/network';
+
+// 获取服务
+const networkService = services.get(NetworkServiceToken);
+```
+
+## 实际示例
+
+### 完整的多人游戏客户端
+
+```typescript
+import { World, EntitySystem, Matcher } from '@esengine/ecs-framework';
+import {
+    NetworkPlugin,
+    NetworkIdentity,
+    NetworkTransform,
+    NetworkInputSystem
+} from '@esengine/network';
+
+// 创建游戏世界
+const world = new World();
+
+// 配置网络插件
+const networkPlugin = new NetworkPlugin({
+    serverUrl: 'ws://localhost:3000'
+});
+networkPlugin.install(world.services);
+
+// 注册玩家预制体
+networkPlugin.registerPrefab('player', (netId, ownerId) => {
+    const entity = world.createEntity(`player_${netId}`);
+
+    const identity = new NetworkIdentity(netId, ownerId);
+    entity.addComponent(identity);
+    entity.addComponent(new NetworkTransform());
+
+    // 如果是本地玩家，添加输入组件
+    if (identity.bIsLocalPlayer) {
+        entity.addComponent(new LocalInputComponent());
+    }
+
+    return entity;
+});
+
+// 连接服务器
+async function startGame() {
+    try {
+        await networkPlugin.connect('Player1');
+        console.log('已连接! 玩家 ID:', networkPlugin.localPlayerId);
+    } catch (error) {
+        console.error('连接失败:', error);
+    }
+}
+
+// 游戏循环
+function gameLoop(deltaTime: number) {
+    world.update(deltaTime);
+}
+
+startGame();
+```
+
+### 处理输入
+
+```typescript
+class LocalInputHandler extends EntitySystem {
+    private _inputSystem: NetworkInputSystem;
+
+    constructor() {
+        super(Matcher.all(NetworkIdentity, LocalInputComponent));
+    }
+
+    protected onAddedToWorld(): void {
+        this._inputSystem = this.world.getSystem(NetworkInputSystem);
+    }
+
+    protected processEntity(entity: Entity, dt: number): void {
+        const identity = entity.getComponent(NetworkIdentity);
+        if (!identity.bIsLocalPlayer) return;
+
+        // 读取键盘输入
+        let moveX = 0;
+        let moveY = 0;
+
+        if (keyboard.isPressed('A')) moveX -= 1;
+        if (keyboard.isPressed('D')) moveX += 1;
+        if (keyboard.isPressed('W')) moveY += 1;
+        if (keyboard.isPressed('S')) moveY -= 1;
+
+        if (moveX !== 0 || moveY !== 0) {
+            this._inputSystem.addMoveInput(moveX, moveY);
+        }
+
+        if (keyboard.isJustPressed('Space')) {
+            this._inputSystem.addActionInput('jump');
+        }
+    }
+}
+```
+
+## 最佳实践
+
+1. **合理设置同步频率**：根据游戏类型选择合适的 `tickRate`，动作游戏通常需要 20-60 Hz
+
+2. **使用插值延迟**：设置适当的 `interpolationDelay` 来平衡延迟和平滑度
+
+3. **客户端预测**：对于本地玩家使用客户端预测减少输入延迟
+
+4. **预制体管理**：为每种网络实体类型注册对应的预制体工厂
+
+5. **权限检查**：使用 `bHasAuthority` 检查是否有权限修改实体
+
+6. **连接状态**：监听连接状态变化，处理断线重连
+
+```typescript
+networkService.setCallbacks({
+    onConnected: () => console.log('已连接'),
+    onDisconnected: () => {
+        console.log('已断开');
+        // 处理重连逻辑
+    }
+});
+```
