GetShaderInputType (Light)

Introduced

5.0

Description

Returns the shader input type for a parameter. If the parameter cannot be connected to a shader, GetShaderInputType returns siUnknownParameterType.

Scripting Syntax

Light.GetShaderInputType( ParameterScriptName )

C# Syntax

siShaderParameterType Light.GetShaderInputType( String Parametername );

Parameters

Return Value

siShaderParameterType

Examples

JScript Example

// Create a scene with an object lit by a spotlight
var root = Application.ActiveProject.ActiveScene.Root;

var grid = root.AddGeometry( "Grid", "MeshSurface" );
scale( grid, 2, 2, 2, siAbsolute );

var cone = root.AddGeometry( "Cone", "MeshSurface" );
translate(cone, 0, 1.3, 0 );

var light = root.AddLight( "LightSpot", true, "SpotLight" );

ApplyCns( "Position", light.interest, cone );
ApplyCns( "Orientation", light.interest, cone );

translate( light, 4, 6, 4);

// List the names and input types of all parameters that support shader connections
var eParams = new Enumerator(light.parameters);

for ( ; !eParams.atEnd(); eParams.moveNext() )
{
   var param = eParams.item();

   if (param.capabilities & siTexturable)
   {
       var inputtype = light.GetShaderInputType(param.scriptname);

       // This parameter supports a shader connection
       logmessage( param.fullname + " has shader inputtype = " + ShaderParameterTypeAsText(type) );
