FCurveSelection (XSIApplication)

Introduced

6.0

Description

Returns an FCurveCollection containing each FCurve objects with selected keys. The selected keys can be retrieved by calling FCurve.SelectedKeys on each fcurve in the Selection.

C# Syntax

// get accessor
FCurveCollection rtn = XSIApplication.FCurveSelection;

Examples

JScript Example

/* 
   This example illustrates how to get the fcurve key selection
*/

// Create a new scene
NewScene(null, false);

// Create a null
oNull = Application.GetPrim("Null");

// Get the posx parameter of the null
oPosX = oNull.posx

// Create array of time-value pairs
aKeys = new Array(  0.00, 5.00,
          1.00, 6.00,
          2.00, 7.00,
          3.00, 8.00,
          4.00, 9.00,
          5.00, 10.00 );

// Create an empty FCurve
oFCurve = oPosX.AddFCurve2( null, siStandardFCurve );

// Set the fcurve keys
oFCurve.SetKeys( aKeys );

// Select some keys
SelectKeysInTimespan(oPosX, siSetKeySelection, 2, 4, siInputParameters);

// Get selected fcurves
oFCurves = Application.FCurveSelection;

// Print selected key information
for (var i=0; i<oFCurves.Count; i++) {
   var keys = oFCurves(i).SelectedKeys;
   var msg = 'FCurve ' + i + ' has ' + keys.count + ' keys selected';
   if (keys.Count > 0) {
       msg += ' at frames: [';
       for (var j = 0; j < keys.Count; j++) {
          if ( j > 0 ) { msg += ', '; }
          msg += keys(j).Time;
       }
       msg += ']';
   }
   Application.LogMessage( msg, siInfo );
}

// Produces the following output:
//
//INFO : FCurve 0 has 3 keys selected at frames: [2, 3, 4]
