WPF制作歌词动画

最近再做一个UWP的音乐播放器,今天实现了歌词动画,不是滚动的,滚动的慢慢研究
思路:在右边放了三个textBlock,设置 textBlock的effect属性
<TextBlock.Effect>
                            <BlurEffect Radius="0"></BlurEffect>
                </TextBlock.Effect>
就是模糊效果。
中间的textBlock没有使用动画
动画播放时间就是歌词上一句跟下语句的时间差
下面放后台动画代码
 Storyboard DownLrcStory = new Storyboard();
                       
                        DoubleAnimation up = new DoubleAnimation(0, 30, new Duration(TimeSpan.FromSeconds(time)));
                        DoubleAnimation next = new DoubleAnimation(30, 0, new Duration(TimeSpan.FromSeconds(nextTime)));
                        up.RepeatBehavior = RepeatBehavior.Forever;
                        DownLrcStory.Children.Add(up);
                        DownLrcStory.Children.Add(next);
                        Storyboard.SetTarget(up, lrcDown);
                        Storyboard.SetTarget(next, lrcNext);
                        Storyboard.SetTargetProperty(up, new PropertyPath("Effect.Radius"));
                        Storyboard.SetTargetProperty(next, new PropertyPath("Effect.Radius"));
                        DownLrcStory.Begin();
