Unet學習：
1 場景中有空物體挂載NetWokManager 和NetWork Manager HUD(負責UI)。
2 要在伺服器端生成的物品 都要加上 NetWorkIdentity 才可以指派給Registered Spawnable Prefabs。
3 PlayerPrefabs 要更新資訊加上 Network Transform元件與 NetworkIdentity元件 。
勾選 Local Player Authority 本地權限 表示是用戶端。
NetworkIdentity是用于網絡識别的辨別符， 有伺服器權限Server Only（不能被本地權限玩家設定權限），和本地權限Local Player Authority。
另外想要在客服端/伺服器 執行一些操作，可以讓腳本繼承 NetworkBehaviour 類。
通過 isServer/isClient 變量 進行判斷 或者 通過 添加特性。
[Commd] 用戶端調用，伺服器運作,下面的方法要加Cmd字首，
[clientRpc] 用戶端 下面方法要加Rpc字首 表示 用戶端調用。
網絡遊戲 基本上遊戲邏輯都在伺服器調用，與角色行為相關的都在LocalPlayer調用。
NewtworkIdentity表示 隻會在服務端運作，但是可以擁有 本地玩家權限。
OnStartSevert 在伺服器建立時 調用。
NetworkStartPosition 元件， 遊戲啟動時， 玩家生成的位置，需要在NetworkManager中設定 玩家生成方法為 Round Robin
https://docs.unity3d.com/ScriptReference/Networking.NetworkBehaviour.html
NetworkBehaviour Api
Properties
| connectionToClient | The NetworkConnection associated with this NetworkIdentity. This is only valid for player objects on the server. |
| connectionToServer | The NetworkConnection associated with this NetworkIdentity. This is only valid for player objects on the server. |
| hasAuthority | This returns true if this object is the authoritative version of the object in the distributed network application. |
| isClient | Returns true if running as a client and this object was spawned by a server. |
| isLocalPlayer | This returns true if this object is the one that represents the player on the local machine. |

Public Methods
| ClearAllDirtyBits | This clears all the dirty bits that were set on this script by SetDirtyBits(); |
| GetNetworkChannel | This virtual function is used to specify the QoS channel to use for SyncVar updates for this script. |
| GetNetworkSendInterval | This virtual function is used to specify the send interval to use for SyncVar updates for this script. |

| InvokeSyncEvent | Manually invoke a SyncEvent. |
| OnCheckObserver | Callback used by the visibility system to determine if an observer (player) can see this object. |

| OnNetworkDestroy | This is invoked on clients when the server has caused this object to be destroyed. |
| OnRebuildObservers | Callback used by the visibility system to (re)construct the set of observers that can see this object. |

| PreStartClient | An internal method called on client objects to resolve GameObject references. |
| SetDirtyBit | Used to set the behaviour as dirty, so that a network update will be sent for the object. |
方法就比較多了
ClearAllDirtyBits 清除在腳本上的所有标志位 虛函數
GetNetworkChannel 擷取網絡通道 此虛拟函數用于列舉用于此腳本的[SyncVar]更新的QoS通道。 SyncVar 同步變量 特性 傳回值是int 傳回是 此腳本的 QoS通道 虛函數
GetNetworkSendInterval 此虛拟函數用于傳回要為SyncVar使用的發送間隔
傳回 在同步更新之間的發送間隔（秒）
InvokeCommand public virtual bool InvokeCommand(int cmdHash, NetworkReader reader);
手動調用 Command（伺服器） 參數是 Command的哈希名，以及傳遞給Command的參數
InvokeRPC public virtual bool InvokeRPC(int cmdHash, NetworkReader reader);
跟上面類似， 隻不過是調用用戶端。RPC（Remote Procedure Call）就是遠端過程調用 的意思 ，就是遠端調用
| InvokeSyncEvent public virtual bool InvokeSyncEvent(int cmdHash, NetworkReader reader); |
手動調用 同步事件 同步事件哈希名 傳遞給同步事件參數
OnCheckObserver public virtual bool OnCheckObserver(NetworkConnection conn)
通過可見系統使用回調來确定觀察者(玩家)是否可以看到這個對象。
參數是 玩家的網絡連接配接
OnDeserialize public virtual void OnDeserialize(NetworkReader reader, bool initialState);
虛函數，用于覆寫以接收自定義序列化資料。相應的
發送序列化資料的函數是OnSerialize()。
參數 reader 從（stream）流中 讀取 ， 初始狀态
OnNetworkDestroy public void OnNetworkDestroy();
當伺服器有對象要被摧毀時 在用戶端上調用
OnRebuildObservers public bool OnRebuildObservers(HashSet<NetworkConnection> observers, bool initialize);
可見系統 用來（重）一組 可以看到這個物體的觀察者的回調
這個回調的實作應該向觀察者添加可以看到這個對象的玩家的網絡連接配接。
OnSerialize public bool OnSerialize(Networking.NetworkWriter writer, bool initialState);
虛函數 覆寫到 發送 自定義 序列化 資料， 相對應的發送 序列化資料的函數 是 OnDeserialize().反序列化
Writer 用來 寫入流 initialState 初始狀态
初始狀态 标志位 是有用于去區分 第一次序列化對象 與 可以發送的增量更新。
第一次将一個對象 發送給客服，它必須包含一個完整狀态快照，但是後續更新隻包含增量改變，可以節省帶寬。
注意 當初始狀态為true,Synvarhook函數 是不會被調用的，隻在增量更新時調用。
如果一個類有 SyncVars 同步變量，那麼 啟用和反序列化這個函數會被自動加進 類裡。
是以 一個有同步變量的類 也不能有自定義的序列化函數。
這個序列化 函數 應該傳回true,表示應該發送更新。如果傳回true 那麼 腳本 的标志位 被設定到0；如果它傳回false
那麼 這個标志位，沒有被改變。這允許腳本随着時間積累，多次改變，并且當系統已經準備就發送。而不是每一貞；
OnSetLocalVisibility public void OnSetLocalVisibility(bool vis);
可見系統用于 在主機上對象的回調
vis 新的可見狀态
OnStartAuthority public void OnStartAuthority();
在 一個有權限的腳本上調用 ，基于環境，和NetworkIdentity.localPlayerAuthority 本地玩家權限
會在 OnStartSever 和OnStartClient 執行 之後 調用
當 NetworkIdentity.AssignClientAuthority 在伺服器上被調用時，這将會在擁有自己對象的用戶端調用.
當 一個對象被NetworkServer.SpawnWithClientAuthority生成的 ，這将 x會在擁有自己對象的用戶端調用。
OnStartClient 在用戶端啟用時調用每一個NetworkBehaviour
主機上的對象有這個函數調用，因為主機上有本地用戶端。當這個函數在用戶端被調用時， 可以保證正确初始同步變量的值，并使用伺服器最近的一個狀态初始化。
OnStartLocalPlayer public void OnStartLocalPlayer();
當本地玩家對象被建立時調用
在OnStartClient() 執行後 調用,因為 它是被從伺服器上的所有權消息觸發的。
這是一個對本地玩家激活元件或者功能的合适地方，比如 Input 和相機。
OnStartServer public void OnStartServer();
當NetworkBehaviour對象 在伺服器啟用時 ，會被調用。
這個 可以被場景裡的NetworkSever.Listen() 的對象 觸發，或者被NetWorkServer.Spawn()動态生成的對象觸發。
這将會在 主機上的對象 和 專用伺服器上的對象 上被調用
OnStopAuthority public void OnStopAuthority();
當 對象 的 權限被移除時在behaviours 上調用
當 在伺服器上調用 NetworkIdentity.RemoveClientAuthority,就會在擁有這個對象的用戶端上調用。
PreStartClient public void PreStartClient();
一個内部的方法 調用用戶端對象，去解析 遊戲對象的引用
把使用者的代碼放進這個函數中 這是不安全的。因為 它可能 被 網絡 系統的代碼生成過程替代掉。
SetDirtyBit 設定标志位 以便 對象可以發送網絡更新
