v6.0
Scales the fcurve in time or value by a relative amount. The
scaling amount is relative to the keyframe bounding box and the
anchor point so that a value of 0.5 would scale the keys by
50%.
Note: If the FCurve is locked then the method raises an 'Access
Denied' (E_ACCESSDENIED) error.
Warning: You cannot use negative values for scaling with this
method.
FCurve.Scale( [FrameFactor], [ValueFactor], [FrameAnchor], [ValueAnchor] ); |
| Parameter | Type | Description |
|---|---|---|
| FrameFactor | Double | The relative amount to scale the fcurve's time.
Default Value: 1.0 |
| ValueFactor | Double | The relative amount to scale the fcurve's value.
Default Value: 1.0 |
| FrameAnchor | Variant | The center point for frame scaling.
Default Value: 0.0 |
| ValueAnchor | Variant | The center point for value scaling.
Default Value: 0.0 |
//
// This example illustrates how to scale an fcurve to 50% of the original fcurve.
// 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 );
Application.LogMessage( 'Before Scaling:', siInfo );
for (var i = 0; i < oFCurve.Keys.Count; i++)
{
Application.LogMessage( 'Time: ' + oFCurve.Keys(i).Time + ', Value: ' + oFCurve.Keys(i).Value, siInfo );
}
oFCurve.Scale( 0.5, 0.5, 0.0, 7.5 );
Application.LogMessage( 'After Scaling:', siInfo );
for (var i = 0; i < oFCurve.Keys.Count; i++)
{
Application.LogMessage( 'Time: ' + oFCurve.Keys(i).Time + ', Value: ' + oFCurve.Keys(i).Value, siInfo );
}
