Getting shader parameter type

["Daniel Rind" <daniel.rind(at)chello.at>]

Hi!

 

I'm currently writing code to walk XSI shader graphs, and I'm having a little problem with shader parameter types:

 

What is the correct way to retrieve the parameter type of a shader's input parameters?

 

I'm currently trying it with something like:

 

Shader current_shader(...);

 

CParameterRefArray shader_params = current_shader.GetParameters();

 

for (int i = 0; i < shader_params.GetCount(); i++)

{

  Parameter current_parameter(shader_params[i]);

 

  switch (current_parameter.GetValueType())

  {

  case siFloat:

    ...

  case siString:

    ...

  }

}

 

which works only sort of...

 

Color and Vector shader parameters are always siEmpty (so I go probing if the parameter contains further parameters, and then check those), but if I connect another shader to a parameter, the GetValueType always returns siRef (who had the idea to assign 666 to that :P), and I can't find out if it's a float or a color or whatever.

 

I'm sure there is some simple GetParameterType() function that I'm missing, that returns if it's a color, a vector, an int, etc... no matter if anything is connected to it or not... or at least I hope there is?

 

Ciao, Daniel!
