if you used my fx file and that code, yes, it would draw twice, but you'd
only see the second draw as there is no alpha component in it and you would
just draw over the already drawn cube.
What you did in your code, you set the technique handler to an existing
handler, but you were already in the render mode, which just doesnt work.
Your technique is set, and the call within doesn't change anything. Your
//should be like this
works fine, but i'd not change the pointer too much and instead do another
technique handler called g_ptechnique_notex for example. There's a lot of
code there the compiler will just optimize out as its just not needed.
Following lines:
effectDiffuseVariable->SetResource(texture2D);
g_pd3dDevice->IASetInputLayout(vertexLayout);
g_pd3dDevice->IASetVertexBuffers(0,1,&vertexBuffer,&stride,&offset);
g_pd3dDevice->IASetIndexBuffer(indexBuffer,DXGI_FORMAT_R32_UINT,
0);
g_pd3dDevice->IASetPrimitiveTopology(tropologyMode);
are pretty much the same in both codes (why on earth do you call it
effectDiffuseVariable if it is a pointer to a 2D texture?), i'd call it just
once outside the switch. Your DrawLight technique doesnt bother about the
texture. Unneeded code.
