Exemplos

void AnimatingVisualOffset(Visual targetVisual) 
{ 
    var animation = _compositor.CreateVector3KeyFrameAnimation(); 

    // 
    // Define specific easing functions. 
    // 


    var linear = _compositor.CreateLinearEasingFunction(); 

    var easeIn = _compositor.CreateCubicBezierEasingFunction( 
            new Vector2(0.5f, 0.0f), new Vector2(1.0f, 1.0f)); 

    var easeOut = _compositor.CreateCubicBezierEasingFunction( 
            new Vector2(0.0f, 0.0f), new Vector2(0.5f, 1.0f)); 

    // 
    // Add a set of key frames to describe how the Offset should change over time.   
    // 

    animation.InsertKeyFrame(0.00f, new Vector3(100.0f, 100.0f, 0.0f)); 
    animation.InsertKeyFrame(0.25f, new Vector3(300.0f, 100.0f, 0.0f), easeIn); 
    animation.InsertKeyFrame(0.50f, new Vector3(300.0f, 300.0f, 0.0f), linear); 
    animation.InsertKeyFrame(0.75f, new Vector3(100.0f, 300.0f, 0.0f), linear); 
    animation.InsertKeyFrame(1.00f, new Vector3(100.0f, 100.0f, 0.0f), easeOut); 

    // 
    // The animation curve defined by the key frames will scale to match the duration. 
    // 

    animation.Duration = TimeSpan.FromMilliseconds(4000); 

    targetVisual.StartAnimation("Offset", animation); 
} 

Comentários

Se uma animação já estiver associada à propriedade de um objeto quando StartAnimation for chamada, a animação aplicada anterior será desconectada e a nova animação será atribuída. Da mesma forma, definir a propriedade diretamente fará com que a animação anterior seja desconectada e o novo valor da propriedade entrará em vigor.

A tabela a seguir mostra a lista de propriedades animáveis:

Além disso, as propriedades de alguns efeitos no objeto CompositionEffectBrush podem ser animadas:

public:
 virtual void StartAnimation(Platform::String ^ propertyName, CompositionAnimation ^ animation, AnimationController ^ animationController) = StartAnimation;

/// [Windows.Foundation.Metadata.Overload("StartAnimationWithController")]
void StartAnimation(winrt::hstring const& propertyName, CompositionAnimation const& animation, AnimationController const& animationController);

[Windows.Foundation.Metadata.Overload("StartAnimationWithController")]
public void StartAnimation(string propertyName, CompositionAnimation animation, AnimationController animationController);

function startAnimation(propertyName, animation, animationController)

Public Sub StartAnimation (propertyName As String, animation As CompositionAnimation, animationController As AnimationController)

Comentários

O animationController parâmetro permite associar várias animações à propriedade Progress de um único controlador, o que requer menos objetos ExpressionAnimation do que associar várias propriedades do Progress animador a uma propriedade CompositionObject.
