Examples

JScript Example

/*
        This JScript example illustrates how to remove keys from an fcurve. The resample 
        method is used to create the initial keys then the RemoveKey method is used to 
        remove every other key 
*/
// Create a null
Application.NewScene( "", false );
var nullobj = ActiveSceneRoot.AddNull();
// Create an fcurve on the posx parameter from the null
var fc = nullobj.posx.AddFCurve()
// Define the number of keys
var nbkeys = 100 
// Create a key on each frame
fc.Resample();
// Remove every other key
var startframe = fc.GetKeyFrame(0)
var endframe = fc.GetKeyFrame( fc.GetNumKeys()-1 );
// Start editing the fcurve
fc.BeginEdit();
for ( i=startframe; i<=endframe; i+=2 )
{
        fc.RemoveKey(i);
}
// End editing the fcurve and put the undo event onto 
// the undo/redo stack
fc.EndEdit();
