读读武侠

I.渲染属性

const  CHAR CRenderSystem::sz32BitTexturesVar[]                 =   " View_ColorQuality " ;  // "yszl"; // 颜色质量，比特数(16/32位)
const  CHAR CRenderSystem::szDefaultTextureFilteringVar[]     =   " View_TextureFiltering " ; // "cy";         // 采样(高/中/低)
const  CHAR CRenderSystem::szLightmapQualityVar[]             =   " View_LightmapQuality " ; // "dxyy";     // 地形阴影(高/低/无)
const  CHAR CRenderSystem::szAnimationQualityVar[]             =   " View_ObjectMove " ; // "wtdh";     // 静态物体动画(开/关)
const  CHAR CRenderSystem::szPostFilterEnabledVar[]             =   " View_FullScreenLight " ; // "qpfg";     // 全屏泛光效果(开/关)
const  CHAR CRenderSystem::szFSAAVar[]                         =   " View_Fanhunjiao " ; // "fhj";     // 反混角(1/2/4)
const  CHAR CRenderSystem::szShadowTechniqueVar[]             =   " View_HumanLightmap " ; // "rwyy";     // 人物阴影(开/关)
const  CHAR CRenderSystem::szvsyncVar[]                         =   " View_Aplomb " ; // "cztb";     // 垂直同步(开/关)

II.登陆逻辑

加载场景(CRenderSystem::Scene_Load)
------>加载当前场景
           ------>清理静态几何体
           ------>清理硬件缓存  
           ------>清理PASS MAP
          ------>加载场景
                     ------>ExpatParser解析SCENE文件
                     ------>加载地形
------>销毁不使用资源
------>设置lightmap
------>设置环境特效
------>推场景事件GE_SCENE_TRANSED(将进入场景事件推入入CEventSystem::m_mapEventIndex_AsID)
------>设置传送点(从DBC数据库中读出当前场景名作为关键字的场景信息中的传送点)

创建Player对象(绑定相关Plaer属性、设置位置，绑定服务器信息、绑定相机)
推Plaer事件GE_PLAYER_ENTER_WORLD
推角色选择事件(GE_GAMELOGIN_CLOSE_SELECT_CHARACTOR)
推背景界面事件(GE_GAMELOGIN_CLOSE_BACK_GROUND)

转入游戏主循环状态机(CGameProcedure::s_pProcMain)

call statck

 1 WXClient.exe ! CGamePro_Enter::EnterScene
 2 WXClient.exe ! Packets::GCEnterSceneHandler::Execute
 3 WXClient.exe ! Packets::GCEnterScene::Execute
 4 WXClient.exe ! CNetManager::executePacket_CPP_Exception
 5 WXClient.exe ! CNetManager::executePacket_Gen_Exception
 6 WXClient.exe ! CNetManager::ProcessInputStream
 7 WXClient.exe ! CNetManager::ProcessCommands
 8 WXClient.exe ! CNetManager::WaitPacket
 9 WXClient.exe ! CNetManager::TickGameEnterProcedure
10 WXClient.exe ! CNetManager::Tick
11 WXClient.exe ! CGameProcedure::Tick
12 WXClient.exe ! CGamePro_Enter::Tick
13 WXClient.exe ! CGameProcedure::TickActive
14 WXClient.exe ! CGameProcedure::MainLoop

最坏帧率控制

VOID CRenderSystem::RenderFrame(VOID)
{
    if(!Ogre::Root::getSingletonPtr())
    {
        TDThrow("Ogre::Root = 0");
    }

    const UINT MAX_RENDER_INTER_TIME = 2000;

    static UINT s_nLastRenderTime = 0;
    UINT s_nTimeNow = g_pTimeSystem->GetTimeNow();

    if(g_pTimeSystem->CalSubTime(s_nLastRenderTime, s_nTimeNow) > MAX_RENDER_INTER_TIME)
    {
        Ogre::Root::getSingleton().clearEventTimes();
        s_nLastRenderTime = s_nTimeNow;
        return;
    }
    s_nLastRenderTime = s_nTimeNow;
    
    Ogre::Root::getSingleton().renderOneFrame();
}

当主循环暂停后(例如调试中断)，返回后避免逻辑异常。到底是避免神马异常呢？
