如何改变物体坐标

WJN92 2011-09-20 10:56:02

原来我是使用这种方法来转换一个物体的位置的

但是我发现camera移动的时候这个物体就没有移动，那怎么做才能只改变它的物体坐标呢？



void CALLBACK OnFrameRender( IDirect3DDevice9* pd3dDevice, double fTime, float fElapsedTime, void* pUserContext )

{

	HRESULT hr;

	    pd3dDevice->Clear( 0, NULL, D3DCLEAR_TARGET | D3DCLEAR_ZBUFFER, D3DCOLOR_XRGB( 0,255,255 ), 1.0f, 0 );



		pd3dDevice->SetRenderState(D3DRS_LIGHTING, false); 





		if (SUCCEEDED(pd3dDevice->BeginScene()))

		{



			model.Render(pd3dDevice);



			pd3dDevice->SetTransform(D3DTS_WORLD, &m) ;



			room.Render(pd3dDevice);



//*****************************************************

			D3DXMATRIX world = *MyCamera.GetWorldMatrix() ;

			pd3dDevice->SetTransform(D3DTS_WORLD, &world) ;



			// Set view matrix

			D3DXMATRIX view  = *MyCamera.GetViewMatrix() ;

			pd3dDevice->SetTransform(D3DTS_VIEW, &view) ;



			// Set projection matrix

			D3DXMATRIX proj  = *MyCamera.GetProjMatrix() ;

			pd3dDevice->SetTransform(D3DTS_PROJECTION, &proj) ;

//*****************************************************



			pd3dDevice->EndScene();



		}



}





void CALLBACK OnFrameMove( double fTime, float fElapsedTime, void* pUserContext )

{

    MyCamera.FrameMove( fElapsedTime );

    D3DXMatrixRotationY( &m, 45 );    

}
