CompositionObject.StartAnimationGroup(ICompositionAnimationBase) 메서드

정의

네임스페이스:

Windows.UI.Composition

애니메이션 그룹을 시작합니다.

CompositionObject의 StartAnimationGroup 메서드를 사용하면 CompositionAnimationGroup을 시작할 수 있습니다. 그룹의 모든 애니메이션은 개체에서 동시에 시작됩니다.

public:
 virtual void StartAnimationGroup(ICompositionAnimationBase ^ value) = StartAnimationGroup;

void StartAnimationGroup(ICompositionAnimationBase const& value);

public void StartAnimationGroup(ICompositionAnimationBase value);

function startAnimationGroup(value)

Public Sub StartAnimationGroup (value As ICompositionAnimationBase)

매개 변수

value

ICompositionAnimationBase

시작할 애니메이션 그룹입니다.

예제

class PropertyAnimation
{
  PropertyAnimation(Compositor compositor, SpriteVisual heroVisual)
  {
    // Define ImplicitAnimations
    ImplicitAnimationCollection implicitAnimations = compositor.CreateImplicitAnimationCollection();

    // Animate multiple properties on the target when the “Offset” property changes. 
    CompositionAnimationGroup animationGroup = compositor.CreateCompositionAnimationGroup();

    animationGroup.Add(CreateSizeAnimation(compositor));
    animationGroup.Add(CreateRotationAnimation(compositor));

    // Set the CenterPoint so that rotation will be around the center
    heroVisual.CenterPoint = new Vector3((heroVisual.Size.X/2.0f), (heroVisual.Size.Y/2.0f), 0.0f);

    // Start AnimationGroup
    heroVisual.StartAnimationGroup(animationGroup);
  }


  Vector2KeyFrameAnimation CreateSizeAnimation(Compositor compositor)
  {
    Vector2KeyFrameAnimation animation  = compositor.CreateVector2KeyFrameAnimation();

    CubicBezierEasingFunction easing = compositor.CreateCubicBezierEasingFunction(new Vector2(0.80f, 0.0f), new Vector2(0.95f, 1.0f));

    // value (as the animation will target on the “Size” property).
    animation.InsertExpressionKeyFrame(0f, "this.StartingValue", easing);
    animation.InsertExpressionKeyFrame(1f, "this.StartingValue * 2", easing);
    animation.Duration = TimeSpan.FromSeconds(0.25);
    animation.Target = “Size”;

    return animation;
  }


  ScalarKeyFrameAnimation CreateRotationAnimation(Compositor compositor)
  {
    ScalarKeyFrameAnimation animation = compositor.CreateScalarKeyFrameAnimation();

    // Create KeyFrameAnimation to animate RotationAngleInDegrees by 90 degrees.	

    animation.InsertExpressionKeyFrame(0f, "this.StartingValue”);
    animation.InsertExpressionKeyFrame(1f, "this.StartingValue + 90.0f”);
    animation.Duration = TimeSpan.FromSeconds(0.25);
    animation.Target = “RotationAngleInDegrees”;

    return animation;
  }
}

설명

StartAnimationGroup은 CompositionAnimationGroup 을 매개 변수로 사용하여 개체에서 그룹의 모든 애니메이션을 동시에 시작합니다. 그룹의 CompositionAnimation에는 Target 속성에 할당된 값이 있어야 합니다.

모든 애니메이션에 대해 Completed 이벤트를 얻으려면 등록된 Completed 이벤트가 있는 CompositionScopedBatch에서 StartAnimationGroup을 호출해야 합니다.
