角色登場,消失及同步化以下實現客戶端登陸后, 構建角色的登場，消失在游戲場景中.1. 客戶端A登陸成功的話,角色的位置發送給服務器”進入游戲”通知.2. 服務器端接收信息后,發送客戶端A已經存在角色信息，并且發送其它客戶端新的信息.3. 客戶端接收后添加新角色到游戲場景中.客戶端 "進入游戲!" 的信息在PIDL中定義.

global Simple 1000 { JoinGameScene([in] float x, [in] float y, [in] float z, [in] float angle); Player_Appear([in] int hostID, [in] std::wstring userID, [in] float x, [in] float y, [in] float z, [in] float vx, [in] float vy, [in] float vz, [in] float angle); Player_Disappear([in] int hostID); ...

客戶端登陸成功的話，通知服務器 "進入游戲!".

m_stub.NotifyLoginSuccess = (HostID remote, RmiContext rmiContext) => { // join the world! m_PRoxy.JoinGameScene(HostID.HostID_Server, RmiContext.ReliableSend, m_localPlayer.transform.position.x, m_localPlayer.transform.position.y, m_localPlayer.transform.position.z, m_localPlayer.GetComponent<PlayControl>().carAngle); // show 30 ends here ...

現在，添加服務器處理的代碼.

class SimpleServer { DECRMI_Simple_JoinGameScene; ... DEFRMI_Simple_JoinGameScene(SimpleServer) { // validation check auto it = m_remoteClients.find(remote); if (it == m_remoteClients.end()) { return true; } auto& rc = it->second; // update player info rc->m_x = x; rc->m_y = y; rc->m_z = z; rc->m_angle = angle;

以上代碼中JoinGameScene繼續添加一下代碼.

DEFRMI_Simple_JoinGameScene(SimpleServer) { ... assert(it->first == remote); // Let incomer know others, let others know incomers. for (auto otherIter : m_remoteClients) { if (otherIter.first != it->first) { auto& otherRC = otherIter.second; m_proxy.Player_Appear((HostID)it->first, RmiContext::ReliableSend, (HostID)otherIter.first, otherRC->m_userID, otherRC->m_x, otherRC->m_y, otherRC->m_z, otherRC->m_vx, otherRC->m_vy, otherRC->m_vz, otherRC->m_angle); m_proxy.Player_Appear((HostID)otherIter.first, RmiContext::ReliableSend, (HostID)it->first, rc->m_userID, rc->m_x, rc->m_y, rc->m_z, rc->m_vx, rc->m_vy, rc->m_vz, rc->m_angle); } }

以上代碼解析如下：1. 接收到的更新游戲角色的信息。2. 傳遞之前客戶端名單，告知客戶端新用戶的加入。同樣，告知新客戶端現有客戶端的加入。客戶端離開的情況，進行相反的處理. 離開后，出現"客戶端OO消失"的信息.

m_netServer->OnClientLeave = [this](CNetClientInfo* info, ErrorInfo*, const ByteArray&) { // let others know the disappear vector<int> others; for (auto otherIter : m_remoteClients) { others.push_back(otherIter.first); } m_proxy.Player_Disappear((HostID*)others.data(), others.size(), RmiContext::ReliableSend, info->m_HostID); ...

調用以上遠程函數時，變量HostID的數組進入.這樣的話，可對多個設備進行信息發送.添加客戶端中調用Player_Appear的處理代碼.，在游戲場景中角色登場.

public class NetManager : MonoBehaviour { public GameObject m_remotePlayerPrefab; void Start() { m_stub.Player_Appear = (HostID remote, RmiContext rmiContext, int hostID, System.String userID, float x, float y, float z, float vx, float vy, float vz, float angle) => { if (hostID != (int)m_netClient.GetLocalHostID()) { var rot = Quaternion.AngleAxis(angle, new UnityEngine.Vector3(0, 1, 0)); var remotePlayerCharacter = (GameObject)Instantiate(m_remotePlayerPrefab, new UnityEngine.Vector3(x, y, z), rot); remotePlayerCharacter.name = "RemotePlayer/" + hostID.ToString(); } return true; };

設置以下條件.Unity Editor中選擇NetManager GameObject后，在 Inspector中 m_remotePlayerPrefab下添加名為RemotePlayer的Prefab.如果沒有 RemoteCar Prefab的話，制作場景內LocalPlayer的復制版后，并刪除所有的 Script Behavior.調用Player_Disappear后, 此角色在游戲場景中被刪除.

m_stub.Player_Disappear = (Nettention.Proud.HostID remote, Nettention.Proud.RmiContext rmiContext, int hostID) => { var g = GameObject.Find("RemotePlayer/" + hostID.ToString()); if (g != null) { Destroy(g); } return true; };

現在進行測試. 運行兩個以上的客戶端后，角色登場.首先會出現角色的位置，但是無法操控，下篇將繼續講述.第八篇：Unity結合C++開發服務器實現多人游戲（八）
