Hi,

 

I've been rewriting my engine so that it doesn't use D3DX and I've gotten almost everything done ... except I can't get SetVertexShaderConstantB/I to work. SetVertexShaderConstantF works just fine (and I'm considering just using that, but I'm bullheaded).

 

So, in my vertex shader I'll have something like:

bool bIsSelected : register(c4);

And in my rendering path, after I have called SetVertexShader, I will do something like:

         uint u = 1;
         hr = gp_DXInterface->SetVertexShaderConstantB(4, (const BOOL*)&u, 1);

Yet, bIsSelected will always be false.  I don't see any errors or warnings.  Has anyone else got these functions to work?

 

EDIT:  For what it's worth, calling SetVertexShaderConstantF works to set bIsSelected.
