Setting a Float Array for shaders
Author
yup you are right passing a normal float also fails, but i don't understand, i can pass the matrix properly.

i still can't find a solution, does anyone know what is wrong with my code?
I haven't seen it in this thread yet, but something Simon suggested - check the debug output. It's very good at elaborating on errors [smile]
If you're not familiar with the DX debug's then check out the link in my signiture.
You should also try something like:
if( FAILED( ... ) ){ OutputDebugString( L"Error occured whilst ...\n" );}as that'll not only give you a line to break-point on, but also a convenient message in your debug output to search for. If you're using the debug runtimes, then whatever appears above that line in the debug output is likely to be the reason it failed.
Also, given that the ID3DXConstantTable is just a thin wrapper over the device's constant setting/getting interface, are you definitely sure that something else isn't overwriting the values you're setting?

however if its weird i don't understand, if i use:
D3DXVECTOR4 Ambient(1.0, 1.0, 1.0, 1.0);
ConstantTable->SetVector(gD3DDevice, "Ambient", &Ambient);
Its works perfectly ok
Edit: thanks for teaching me how to use the debugger, yup i follow the method of:
if (FAILED(...))
MessageBox(....);
Thats why i know the SetFloatArray failed
D3DXVECTOR4 Ambient(1.0, 1.0, 1.0, 1.0);
ConstantTable->SetVector(gD3DDevice, "Ambient", &Ambient);

err people just asking does it matters for the version of the SDK? maybe it is not supported or ready yet?
