## ProjectItem.AddScriptedOpFromFile

### Introduced

v4.0

### Description

Creates a new scripted operator and connects its output to this object. If the scripting file is not specified then a default implementation is used. 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 used.

### C# Syntax

    CustomOperator ProjectItem.AddScriptedOpFromFile( String bszFileName, Object vInputs, String bszName, String bszLanguage, siConstructionMode in_constructionmode );

### Scripting Syntax

    oReturn = ProjectItem.AddScriptedOpFromFile( [FileName], Inputs, [Name], [Language], [ConstructionMode] );

### Return Value

CustomOperator

### 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
ConstructionMode | siConstructionMode | The location in the construction stack where the operator should be created. This only applies to output connections made to Geometry objects; this mode will be ignored for all other types of connections. Default Value: siConstructionModeDefault

### Examples

#### JScript Example

    /*

    	This example creates a simple expression-like scripted operator

    	which constrains the rotation of one object to another

    */

    NewScene( null, false );

    var obj1 = GetPrim( "null" );

    var obj2 = GetPrim( "null" );

    // Create script file on disk

    var filename = XSIUtils.BuildPath( 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 operator

    var col = XSIFactory.CreateActiveXObject( "XSI.Collection" );

    col.Add( obj1.Kinematics.Global );

    col.Add( obj2.Kinematics.Global );

    obj1.Kinematics.Global.AddScriptedOpFromFile( filename, col, "myexpr", "JScript" );

    function myexpr_Update( ctx, out, inglobal1, inglobal2 )

    {

    	var transfo = inglobal1.Value.Transform;

    	var rot = XSIMath.CreateRotation();

    	inglobal2.Value.Transform.GetRotation(rot);

    	transfo.SetRotation( rot );

    	out.Value.Transform = transfo;

    }
