AddScriptedOpFromFile (Parameter)

AddScriptedOpFromFile (Parameter)

Introduced

4.0

Description

Creates a new scripted operator and connects its output to this object. If the scripting file is not specified then a default implementation will be used. For parameter connections a simple assignment of the current value will be created; for example, 'out.Value = 0.00'.

Specifying the scripting language is optional. If not specified then the language associated with the file extension will be used. If this cannot be determined then the current scripting language user preference will be used.

Scripting Syntax

Parameter.AddScriptedOpFromFile( [FileName], Inputs, [Name], [Language] )

C# Syntax

CustomOperator Parameter.AddScriptedOpFromFile( String bszFileName, Object vInputs, String bszName, String bszLanguage );

Parameters

Parameter	Type	Description
FileName	String	The script filename containing the implementation of the scripted operator.
Inputs	List	List of objects or parameters to be connected to input ports.
Name	String	The name of the new operator Default Value: ScriptedOp
Language	String	The script language of the new scripted operator Default Value: Preference value from application.preferences.scripting.language

Examples

JScript Example

/*
   This example demonstrates how to create a simple expression-like scripted operator
   to constrain the posx of an object to its posy value
*/
NewScene(null, false);
var obj = Application.ActiveSceneRoot.AddNull();

// Create script file on disk
var filename = Application.InstallationPath( siUserPath ) + "\\Data\\Scripts\\myexpr_sop.js";

var fso = new ActiveXObject( "Scripting.FileSystemObject" );
var f = fso.CreateTextFile( filename, true );
f.Write( myexpr_Update.toString() );
f.Close();

// Apply scripted operator
obj.posx.AddScriptedOpFromFile( filename, obj.posy, "myexpr", "JScript" );

// Expression Update function
function myexpr_Update( ctx, out, inposy )
{
   out.Value = inposy;
}
