在上一篇文章中，我們以客戶端的角度去寫了玩家移動的Script，那這篇文章就從上篇文章接續下去。
在伺服器端，我們在之前建立的 Server 腳本中在玩家連線後把它們先初始化；我們需要一個ServerHandle來處理收到封包後，後續要執行的動作指令，我們還需要一個Player腳本來處理所有角色的移動。

在Server腳本裡初始化封包

private static void InitializeServerData()        
{ 
    for (int i = 1; i <= MaxPlayers; i++)            
    { 
        clients.Add(i, new Client(i));            
    }  
    packetHandlers = new Dictionary<int, PacketHandler>()
    {                
        { (int)ClientPackets.welcomeReceived, ServerHandle.WelcomeReceived },                
        { (int)ClientPackets.playerMovement, ServerHandle.PlayerMovement },            
    }; 
    Console.WriteLine("Initialized packets.");        
}

在ServerHandle腳本裡

public static void PlayerMovement(int _fromClient, Packet _packet)        
{ 
    bool[] _inputs = new bool[_packet.ReadInt()]; 
    for(int i = 0; i < _inputs.Length; i++)            
    { 
        _inputs[i] = _packet.ReadBool();            
    } 
    Quaternion _rotation = _packet.ReadQuaternion();  
    Server.clients[_fromClient].player.SetInput(_inputs, _rotation);        
}

在Player腳本裡

public void Update()        
{ 
    Vector2 _inputDirection = Vector2.Zero; 
    if (inputs[0])            
    { 
        _inputDirection.Y += 1;            
    } 
    if (inputs[1])
    {
        _inputDirection.Y -= 1;            
    } 
    if (inputs[2])            
    { 
        _inputDirection.X += 1;            
    } 
    if (inputs[3])            
    { 
        _inputDirection.X -= 1;            
    }  Move(_inputDirection);        
}  

private void Move(Vector2 _inputDirection)        
{ 
    Vector3 _forward = Vector3.Transform(new Vector3(0, 0, 1), rotation); 
    Vector3 _right = Vector3.Normalize(Vector3.Cross(_forward, new Vector3(0, 1, 0)));  
    Vector3 _moveDirection = _right * _inputDirection.X + _forward * _inputDirection.Y; 
    position += _moveDirection * moveSpeed;  
    ServerSend.PlayerPosition(this); ServerSend.PlayerRotation(this);        
}  

public void SetInput(bool[] _inputs, Quaternion _rotation)        
{ 
    inputs = _inputs; rotation = _rotation;          
}
