Unet学习：
1 场景中有空物体挂载NetWokManager 和NetWork Manager HUD(负责UI)。
2 要在服务器端生成的物品 都要加上 NetWorkIdentity 才可以赋值给Registered Spawnable Prefabs。
3 PlayerPrefabs 要更新信息加上 Network Transform组件与 NetworkIdentity组件 。
勾选 Local Player Authority 本地权限 表示是客户端。
NetworkIdentity是用于网络识别的标识符， 有服务器权限Server Only（不能被本地权限玩家设置权限），和本地权限Local Player Authority。
另外想要在客服端/服务器 执行一些操作，可以让脚本继承 NetworkBehaviour 类。
通过 isServer/isClient 变量 进行判断 或者 通过 添加特性。
[Commd] 客户端调用，服务器运行,下面的方法要加Cmd前缀，
[clientRpc] 客户端 下面方法要加Rpc前缀 表示 客户端调用。
网络游戏 基本上游戏逻辑都在服务器调用，与角色行为相关的都在LocalPlayer调用。
NewtworkIdentity表示 只会在服务端运行，但是可以拥有 本地玩家权限。
OnStartSevert 在服务器创建时 调用。
NetworkStartPosition 组件， 游戏启动时， 玩家生成的位置，需要在NetworkManager中设置 玩家生成方法为 Round Robin

NetworkBehaviour Api
Properties

| 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. |
| InvokeCommand | Manually invoke a Command. |
| InvokeRPC | Manually invoke an RPC function. |
| InvokeSyncEvent | Manually invoke a SyncEvent. |
| OnCheckObserver | Callback used by the visibility system to determine if an observer (player) can see this object. |
| OnDeserialize | Virtual function to override to receive custom serialization data. The corresponding function to send serialization data is OnSerialize(). |
| 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. |
| OnSerialize | Virtual function to override to send custom serialization data. The corresponding function to send serialization data is OnDeserialize(). |
| OnSetLocalVisibility | Callback used by the visibility system for objects on a host. |
| OnStartAuthority | This is invoked on behaviours that have authority, based on context and NetworkIdentity.localPlayerAuthority. |
| OnStartClient | Called on every NetworkBehaviour when it is activated on a client. |
| OnStartLocalPlayer | Called when the local player object has been set up. |
| OnStartServer | This is invoked for NetworkBehaviour objects when they become active on the server. |
| OnStopAuthority | This is invoked on behaviours when authority is removed. |
| 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. |
方法就比较多了
ClearAllDirtyBits 清除在脚本上的所有标志位 虚函数
GetNetworkChannel 获取网络通道 此虚拟函数用于列举用于此脚本的[SyncVar]更新的QoS通道。 SyncVar 同步变量 特性 返回值是int 返回是 此脚本的 QoS通道 虚函数
GetNetworkSendInterval 此虚拟函数用于返回要为SyncVar使用的发送间隔
返回 在同步更新之间的发送间隔（秒）
InvokeCommand public virtual bool InvokeCommand(int cmdHash, NetworkReader reader);
手动调用 Command（服务器） 参数是 Command的哈希名，以及传递给Command的参数
InvokeRPC public virtual bool InvokeRPC(int cmdHash, NetworkReader reader);
跟上面类似， 只不过是调用客户端。RPC（Remote Procedure Call）就是远程过程调用 的意思 ，就是远程调用
| InvokeSyncEvent public virtual bool InvokeSyncEvent(int cmdHash, NetworkReader reader); |
手动调用 同步事件 同步事件哈希名 传递给同步事件参数
OnCheckObserver public virtual bool OnCheckObserver(NetworkConnection conn)
通过可见系统使用回调来确定观察者(玩家)是否可以看到这个对象。
参数是 玩家的网络连接
OnDeserialize public virtual void OnDeserialize(NetworkReader reader, bool initialState);
虚函数，用于覆盖以接收自定义序列化数据。相应的
发送序列化数据的函数是OnSerialize()。
参数 reader 从（stream）流中 读取 ， 初始状态
OnNetworkDestroy public void OnNetworkDestroy();
当服务器有对象要被摧毁时 在客户端上调用
OnRebuildObservers public bool OnRebuildObservers(HashSet<NetworkConnection> observers, bool initialize);
可见系统 用来（重）一组 可以看到这个物体的观察者的回调
这个回调的实现应该向观察者添加可以看到这个对象的玩家的网络连接。
OnSerialize public bool OnSerialize(Networking.NetworkWriter writer, bool initialState);
虚函数 覆盖到 发送 自定义 序列化 数据， 相对应的发送 序列化数据的函数 是 OnDeserialize().反序列化
Writer 用来 写入流 initialState 初始状态
初始状态 标志位 是有用于去区分 第一次序列化对象 与 可以发送的增量更新。
第一次将一个对象 发送给客服，它必须包含一个完整状态快照，但是后续更新只包含增量改变，可以节省带宽。
注意 当初始状态为true,Synvarhook函数 是不会被调用的，只在增量更新时调用。
如果一个类有 SyncVars 同步变量，那么 启用和反序列化这个函数会被自动加进 类里。
所以 一个有同步变量的类 也不能有自定义的序列化函数。
这个序列化 函数 应该返回true,表示应该发送更新。如果返回true 那么 脚本 的标志位 被设置到0；如果它返回false
那么 这个标志位，没有被改变。这允许脚本随着时间积累，多次改变，并且当系统已经准备就发送。而不是每一贞；
OnSetLocalVisibility public void OnSetLocalVisibility(bool vis);
可见系统用于 在主机上对象的回调
vis 新的可见状态
OnStartAuthority public void OnStartAuthority();
在 一个有权限的脚本上调用 ，基于环境，和NetworkIdentity.localPlayerAuthority 本地玩家权限
会在 OnStartSever 和OnStartClient 执行 之后 调用
当 NetworkIdentity.AssignClientAuthority 在服务器上被调用时，这将会在拥有自己对象的客户端调用.
当 一个对象被NetworkServer.SpawnWithClientAuthority生成的 ，这将 x会在拥有自己对象的客户端调用。
OnStartClient 在客户端启用时调用每一个NetworkBehaviour
主机上的对象有这个函数调用，因为主机上有本地客户端。当这个函数在客户端被调用时， 可以保证正确初始同步变量的值，并使用服务器最近的一个状态初始化。
OnStartLocalPlayer public void OnStartLocalPlayer();
当本地玩家对象被建立时调用
在OnStartClient() 执行后 调用,因为 它是被从服务器上的所有权消息触发的。
这是一个对本地玩家激活组件或者功能的合适地方，比如 Input 和相机。
OnStartServer public void OnStartServer();
当NetworkBehaviour对象 在服务器启用时 ，会被调用。
这个 可以被场景里的NetworkSever.Listen() 的对象 触发，或者被NetWorkServer.Spawn()动态生成的对象触发。
这将会在 主机上的对象 和 专用服务器上的对象 上被调用
OnStopAuthority public void OnStopAuthority();
当 对象 的 权限被移除时在behaviours 上调用
当 在服务器上调用 NetworkIdentity.RemoveClientAuthority,就会在拥有这个对象的客户端上调用。
PreStartClient public void PreStartClient();
一个内部的方法 调用客户端对象，去解析 游戏对象的引用
把用户的代码放进这个函数中 这是不安全的。因为 它可能 被 网络 系统的代码生成过程替代掉。
SetDirtyBit 设置标志位 以便 对象可以发送网络更新
