Return Value

FCurveKeyCollection

Examples

JScript Example

// 
// This example illustrates how to create an empty FCurveKeyCollection and populate it

// 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 );

// Create an empty key collection
aKeyColl = XSIFactory.CreateFCurveKeyCollection();

// Add every other key to the collection
for (var i = 0; i < oFCurve.Keys.Count; i+=2) 
{
   aKeyColl.Add( oFCurve.Keys(i) );
}

// Print out the collection
for (var i = 0; i < aKeyColl.Count; i++) 
{
   Application.LogMessage( 'Time: ' + aKeyColl(i).Time + ', Value: ' + aKeyColl(i).Value, siInfo );
}

// Produces the following output:
//
//INFO : Time: 0, Value: 5
//INFO : Time: 2, Value: 7
//INFO : Time: 4, Value: 9
