Question

我试图让这个动画工作但是出于某些原因，当Dispatch计时器调用时，没有任何事情发生，任何想法？

    public static void Grass2(Canvas canvas, int boundry)
    {
        foreach (var element in canvas.Children.OfType<Image>())
        {
            var elementName = Regex.Split(element.Name, "_");
            if (elementName[0] == "grass")
            {
                var skewGrass = new DoubleAnimation
                    {
                        From = 0,
                        To = boundry,
                        Duration = new Duration(TimeSpan.FromMilliseconds(100)),
                        RepeatBehavior = RepeatBehavior.Forever,
                        EasingFunction = new BackEase(),
                        AutoReverse = true
                    };
                element.BeginAnimation(SkewTransform.AngleXProperty, skewGrass);
            }
        }
    }

您正尝试在Image类型的对象上设置SkewTransform.AngleXProperty的动画。这不起作用，因为Image没有这个属性。但是，图像的RenderTransform可能设置为SkewTransform，并且可以设置SkewTransform的动画：

...
// each element's RenderTransform must be a SkewTransform
var transform = (SkewTransform)element.RenderTransform;
transform.BeginAnimation(SkewTransform.AngleXProperty, skewGrass);

Doubleanimation歪斜不工作
