I want to change the vertices properties in the vertex buffer, but this work ONLY ONCE, then the "pVertices[j].p *= xVariable;" line do nothing. What's wrong? Thanks: George Varga The Code for create: -------------------- m_pXFileObject = new CD3DMesh(); m_pXFileObject->Create( m_pd3dDevice, strXFileBuffer ); m_pXFileObject->SetFVF( m_pd3dDevice, D3DFVF_MODELVERTEX ); The Code for manage: -------------------- m_pXFileObject->GetSysMemMesh()->GetVertexBuffer( &pVB ); dwNumVertices = m_pXFileObject[x]->GetSysMemMesh()->GetNumVertices(); pVB->Lock( 0, 0, (BYTE**)&pVertices, 0 ); for( DWORD j=0; j < dwNumVertices; j++ ) { pVertices[j].p *= xVariable; } pVB->Unlock(); pVB->Release(); [edited by - GeorgeV on August 30, 2002 3:10:43 PM]

Thanks for the answer.

The increment for "for" was correct, but the HTML list not show correct the for increment line. I changed.

Thanks for the answer.

I modified the code: must reinitialize the "DeviceObjects" with "m_pXFileObject" and "m_pd3dDevice", then I can modified the vertices in vertex buffer in every frame.
