/* 

	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]
