一个问题困扰好久的问题，我把主要的程序贴出来。这个是主程序

然后还有一个叫GameEngine_ScnenManager的类

if(FAILED(m_pIDirect3D->GetAdapterDisplayMode(D3DADAPTER_DEFAULT, &d3dDisplayMode)))
return false;
//设置屏幕窗口大小
if(bFullScreen){
m_iWidth=iWidth;
m_iHeight=iHeight;
}
else{
if(iWidth>0 && iHeight>0){
m_iWidth=iWidth;
m_iHeight=iHeight;
GetClientRect(m_hWnd,&clientRect);
}
else
return false;
}
//窗口,则移动到屏幕中央位置
if(!bFullScreen){
iWndPosX=(d3dDisplayMode.Width - m_iWidth)/2;
iWndPosY=(d3dDisplayMode.Height - m_iHeight)/2;
GetWindowRect(m_hWnd,&wndRect);
iTitlebarWidth=(wndRect.right - wndRect.left) - clientRect.right;
iTitlebarHeight=(wndRect.bottom - wndRect.top) - clientRect.bottom;
MoveWindow(m_hWnd,iWndPosX,iWndPosY,iTitlebarWidth+m_iWidth,iTitlebarHeight+m_iHeight,true);
}
//设置D3D设备的属性参数
D3DPRESENT_PARAMETERS d3dPresent_Param; //渲染参数结构体

}
else{
d3dPresent_Param.Windowed=true;
d3dPresent_Param.SwapEffect=D3DSWAPEFFECT_DISCARD;
}
//简单的硬件、软件渲染选择
D3DCAPS9 d3dcaps;
bool bHardwareProcess;
m_pIDirect3D->GetDeviceCaps(D3DADAPTER_DEFAULT,D3DDEVTYPE_HAL,&d3dcaps);
if(d3dcaps.DevCaps & D3DDEVCAPS_HWTRANSFORMANDLIGHT){
bHardwareProcess=true;
}
else{
bHardwareProcess=false;
}
//创建d3d设备
if(bHardwareProcess){
if(FAILED(m_pIDirect3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, m_hWnd,
D3DCREATE_HARDWARE_VERTEXPROCESSING, &d3dPresent_Param,
&m_pIDirect3DDevice))){
return false;
}
}
else{
if(FAILED(m_pIDirect3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, m_hWnd,
D3DCREATE_SOFTWARE_VERTEXPROCESSING, &d3dPresent_Param,
&m_pIDirect3DDevice))){
return false;
}
}
//设置渲染状态
m_pIDirect3DDevice->SetRenderState(D3DRS_LIGHTING,false);
m_pIDirect3DDevice->SetRenderState(D3DRS_ZENABLE,true);
m_pIDirect3DDevice->SetRenderState(D3DRS_ALPHATESTENABLE,false);
m_pIDirect3DDevice->SetRenderState(D3DRS_ALPHABLENDENABLE,false);
m_pIDirect3DDevice->SetSamplerState(0,D3DSAMP_MAGFILTER,D3DTEXF_LINEAR);
m_pIDirect3DDevice->SetSamplerState(0,D3DSAMP_MINFILTER,D3DTEXF_LINEAR);
//创建精灵
if(FAILED(D3DXCreateSprite(m_pIDirect3DDevice,&m_pSprite)))
return false;
return true;
}
大家可以看到关于场景初始化的部分有重复，我想用GameEngine_SceneManager里的Init（）和SetRenderMode（）函数对main里的场景初始化的部分进行代替，可是代替之后，骨骼动画就用不了了，问题是怎样对g_pIDirect3DDevice进行变换，有兴趣的朋友可以加我QQ:739880612
我可以把所有代码发给你
