im having troubles locking the vertex buffer, it keeps saying the call is invalid. create buffer code:

pD3DDevice->CreateVertexBuffer(newTerrainChunk.numOfVertices * sizeof(TERRAIN_D3DFVF),
                                               0, TERRAIN_D3DFVF,
                                               D3DPOOL_DEFAULT, &newTerrainChunk.pVertexBuffer, 0)

code to lock:

void* pVertices;

newTerrainChunk.pVertexBuffer->Lock(0, 0, (void**)&pVertices, D3DLOCK_DISCARD);

Hi,

Try:

void* pVertices;newTerrainChunk.pVertexBuffer->Lock(0, newTerrainChunk.numOfVertices, (void**)&pVertices, D3DLOCK_DISCARD);

Regards,
Steve

Calling with 0 as the vertex number should be okay (it should lock the entire vertex buffer).

Instead, make sure you have the debug runtime installed, set the debug output slider to full and run through the debugger. Watch for messages in the debug output window. These''ll tell you what''s wrong.
