Question

WPF很新，但我已经制作了一款Surface应用程序，以吸引人们的关注。

我想做的是，如果人们有一段时间没有触摸屏幕（我已经用计时器录制了这个），我想让我的应用程序中的每个对象“Throb”一个一个引起人们注意的。

我会使用转换或故事板吗？

我最终在计时器上调用了以下方法：

void RunScaleAnimation(FrameworkElement e)
{

var storyboard = new Storyboard();
var easeOut = new BackEase { EasingMode = EasingMode.EaseOut, Amplitude = 0.3 };

double startHeight = e.ActualHeight;
double startWidth = e.ActualWidth;

var growAnimationHOut = new DoubleAnimation(startHeight, startHeight * 1.05,
                                            TimeSpan.FromMilliseconds(100)) { AutoReverse = true };

var growAnimationWOut = new DoubleAnimation(startWidth, startWidth * 1.05,
                                            TimeSpan.FromMilliseconds(100)) { AutoReverse = true };

growAnimationHOut.EasingFunction = easeOut;
growAnimationWOut.EasingFunction = easeOut;

storyboard.Children.Add(growAnimationHOut);
storyboard.Children.Add(growAnimationWOut);

Storyboard.SetTargetProperty(growAnimationWOut, new PropertyPath(FrameworkElement.WidthProperty));
Storyboard.SetTargetProperty(growAnimationHOut, new PropertyPath(FrameworkElement.HeightProperty));

e.BeginStoryboard(storyboard);
}

使对象“悸动”/成长和收缩
