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.

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;
}
