在WPF中，如何从后面的代码中将宽松功能添加到我的动画中？

Question

我正在创建代码的双重保密，我想在其中添加一个宽松的功能，那么我该怎么做？

Answer 1

这就是我的方式：

        DoubleAnimationUsingKeyFrames compassRoseAnimation = new DoubleAnimationUsingKeyFrames();
        compassRoseAnimation.Duration = new Duration(TimeSpan.FromSeconds(2));
        QuarticEase easingFunction = new QuarticEase();
        easingFunction.EasingMode = EasingMode.EaseInOut;
        EasingDoubleKeyFrame startAnimation = new EasingDoubleKeyFrame(previousRotationDegrees, KeyTime.FromPercent(0));
        EasingDoubleKeyFrame endAnimation = new EasingDoubleKeyFrame(newRotationDegrees, KeyTime.FromPercent(1.0), easingFunction);
        compassRoseAnimation.KeyFrames.Add(startAnimation);
        compassRoseAnimation.KeyFrames.Add(endAnimation);

        RotateTransform rotateTransform = new RotateTransform();
        CompassWithNumbersControl.RenderTransform = rotateTransform;
        rotateTransform.BeginAnimation(RotateTransform.AngleProperty, compassRoseAnimation);

Answer 2

不必使用 DoubleAnimationUsingKeyFrames - 只能完成 DoubleAnimation:

CircleEase easing = new CircleEase();  // or whatever easing class you want
easing.EasingMode = EasingMode.EaseInOut;
DoubleAnimation scrollQueue = new DoubleAnimation();
scrollQueue.By = -singleScrollAmt;
scrollQueue.EasingFunction = easing;
scrollQueue.Duration = TimeSpan.FromSeconds(0.5);
MyTextBlock.BeginAnimation(Canvas.TopProperty, scrollQueue);

我自己弄清楚了。我当时正在寻找轻松的属性，但实际上它被称为Keyspline，我必须使用DoubleAniamTionusingKeyframes来获得宽松的功能。
