Exemplos

// Listen for the InertiaStateEntered event
public void InertiaStateEntered(InteractionTracker sender, 	InteractionTrackerInertiaStateEnteredArgs args)
{
  // Grab the Scale velocity out of the args when the event is fired. 
  float scaleVelocity = args.ScaleVelocityInPercentPerSecond;
}

void CustomSpringMotion(float springCoefficient, float dampingCoefficient, float 	maxScale)
{
  // Create the InertiaModifier that will be a custom motion emulating a spring
  InteractionTrackerInertiaMotion modifier = InteractionTrackerInertiaMotion.Create(_compositor);
  modifier.Condition = _compositor.CreateExpressionAnimation("this.Target.NaturalRestingPosition.X > maxScale");
  modifier.Condition.SetScalarParameter("maxScale", maxScale);

  // Utilize the current Velocity of InteractionTracker in the Expression defining 	the custom spring motion
  modifier.Motion = _compositor.CreateExpressionAnimation("(-springStiffnessCoefficient * (this.Target.Position.X – maxScale)) + " +
    "(-dampingCoefficient * this.target.ScaleVelocityInPercentPerSecond");
  modifier.Motion.SetScalarParameter("springStiffnessCoefficient", springCoefficient);
  modifier.Motion.SetScalarParameter("dampingCoefficient", dampingCoefficient);
  modifier.Motion.SetScalarParameter("maxScale", maxScale);
}

Comentários

Ao acessar a propriedade ScaleVelocityInPercentPerSecond do evento InertiaStateEntered, você recuperará uma instantâneo da velocidade calculada com base na Interação. Esse evento só será acionado uma vez depois que a interação tiver ocorrido.
