在 DirectX 9.0 中以后台模式加载资源
我用DirectX9.0制作了一个3D游戏。
我想通过使用线程在后台模式下加载资源。
这是我的代码。
----------------Attakc.h----------------------------------------
#define AFXBEGINTHREAD(pfnThreadProc,pParam) AfxBeginThread(pfnThreadProc, pParam, THREAD_PRIORITY_NORMAL,0,CREATE_SUSPENDED,NULL)
CWinThread* g_pThread = NULL;
volatile bool g_bExitThread = true;
CCriticalSection g_csExitThread;
---- ------------Attakc.cpp----------------------------------------
...
case WM_START:
if(wParam >= 0 && wParam < 18)
{
g_csExitThread.Lock();
g_bExitThread = false;
g_csExitThread.Unlock();
g_pThread = AFXBEGINTHREAD(ThreadFunc,0);
if(NULL == g_pThread)
{
MessageBoxW(0,L"Failed to Create Thread",0,0);
}
g_pThread->m_bAutoDelete = TRUE;
g_pThread->ResumeThread();
wParamTemp = wParam;
lParamTemp = lParam;
uMsgTemp = uMsg;
}
....
UINT ThreadFunc(LPVOID lpParam)
{
while(true)
{
Sleep(1);
g_csExitThread.Lock();
if(true == g_bExitThread)
{
g_csExitThread.Unlock();
break;
}
else
{
g_csExitThread.Unlock();
g_pApp->GotoHole(wParamTemp, lParamTemp);
g_bExitThread = true;
g_pApp->m_nRenderMode = RENDERMODE_SCENE;
g_pApp->StartFlyOver();
g_pApp->m_flyOver.bFirstTime = TRUE;
g_pApp->m_uiLoadingMenu.m_bStart = FALSE;
g_pApp->m_uiLoadingMenu.nTime = 0;
g_pApp->m_uiLoadingMenu.count = 0;
}
}
return 0L;
}
然后，当我运行这个项目时，出现E_OUTOFMEMORY错误。（D3DXCreateTextureFromFile）
我认为这与线程的同步有关。
我没有通过使用线程加载资源的经验。
请帮我。
I have made an 3D Game with DirectX9.0.
I want to load resources in background mode by use thread.
Here is my code.
----------------Attakc.h---------------------------
#define AFXBEGINTHREAD(pfnThreadProc,pParam) AfxBeginThread(pfnThreadProc, pParam, THREAD_PRIORITY_NORMAL,0,CREATE_SUSPENDED,NULL)
CWinThread* g_pThread = NULL;
volatile bool g_bExitThread = true;
CCriticalSection g_csExitThread;
----------------Attakc.cpp---------------------------
...
case WM_START:
if(wParam >= 0 && wParam < 18)
{
g_csExitThread.Lock();
g_bExitThread = false;
g_csExitThread.Unlock();
g_pThread = AFXBEGINTHREAD(ThreadFunc,0);
if(NULL == g_pThread)
{
MessageBoxW(0,L"Failed to Create Thread",0,0);
}
g_pThread->m_bAutoDelete = TRUE;
g_pThread->ResumeThread();
wParamTemp = wParam;
lParamTemp = lParam;
uMsgTemp = uMsg;
}
....
UINT ThreadFunc(LPVOID lpParam)
{
while(true)
{
Sleep(1);
g_csExitThread.Lock();
if(true == g_bExitThread)
{
g_csExitThread.Unlock();
break;
}
else
{
g_csExitThread.Unlock();
g_pApp->GotoHole(wParamTemp, lParamTemp);
g_bExitThread = true;
g_pApp->m_nRenderMode = RENDERMODE_SCENE;
g_pApp->StartFlyOver();
g_pApp->m_flyOver.bFirstTime = TRUE;
g_pApp->m_uiLoadingMenu.m_bStart = FALSE;
g_pApp->m_uiLoadingMenu.nTime = 0;
g_pApp->m_uiLoadingMenu.count = 0;
}
}
return 0L;
}
Then, When I run this project, E_OUTOFMEMORY error appear.(D3DXCreateTextureFromFile)
I think it belong about the thread's synchronization.
I have no experience to load resource by use thread.
Please help me.

初始化 d3d 时是否使用了 D3DCREATE_MULTITHREADED 标志？
Did you used D3DCREATE_MULTITHREADED flag when initializing d3d?
