C# Animation AutoReverse=false，但仍会执行此操作，并且从错误的起点开始

我试图从画布的右下角到左上角获得一个图像，永远重复这个行为。图像不应从左上角到右上角进行反向动画。我是动画新手，所以我用了

此时，我的图像正在从左上角移动到右下角并返回。我尝试更改画布中图像的开始位置，结果，动画使用此位置作为新的起点。我还尝试使用负值，使图像移动到相反的方向。减少片段中的点数量可以缩短动画路径，但没有其他效果。我还将AutoReverse设置为false，而不改变动画行为

我的想法是， -segment类正在用点构建一个圆，但是要使用哪个其他类呢？ -开始位置必须更改，但是如何使对象在屏幕上向上移动而不是向下移动

我的代码

Storyboard animationSB = new Storyboard();

//Image book = createImage(model.keywordCollection[0].cover.small);
Image rope1 = createImage("pack://application:,,,/GUI;component/Resources/rope_trans.png");
rope1.Height = 360.0;
rope1.Width = 185.0;

//Transform to move the book image
TranslateTransform aniRope1 = new TranslateTransform();
this.RegisterName("AnimatedRope1", aniRope1);
rope1.RenderTransform = aniRope1;
Canvas.SetLeft(rope1, 258.659);
Canvas.SetTop(rope1, 583.212);
LeftRope.Children.Add(rope1);


//Anitmation path
PathGeometry animationPath1 = new PathGeometry();
PathFigure pathFigure1 = new PathFigure();
PolyLineSegment lineSegments1 = new PolyLineSegment();
lineSegments1.Points.Add(new Point(LeftRope.ActualWidth, LeftRope.ActualHeight));
lineSegments1.Points.Add(new Point(258.659, 583.212));
lineSegments1.Points.Add(new Point(120.596, 272.665));
lineSegments1.Points.Add(new Point(0, 0));
pathFigure1.Segments.Add(lineSegments1);
animationPath1.Figures.Add(pathFigure1);
animationPath1.Freeze();

//Animate transform to move image along the path on the x-axis
DoubleAnimationUsingPath translateXAnimation1 = new DoubleAnimationUsingPath();
translateXAnimation1.PathGeometry = animationPath1;
translateXAnimation1.Duration = TimeSpan.FromSeconds(6);
translateXAnimation1.Source = PathAnimationSource.X;
translateXAnimation1.AutoReverse = false;

Storyboard.SetTargetName(translateXAnimation1, "AnimatedRope1");
Storyboard.SetTargetProperty(translateXAnimation1, new PropertyPath(TranslateTransform.XProperty));

//Animate transform to move image along the path on the y-axis
DoubleAnimationUsingPath translateYAnimation1 = new DoubleAnimationUsingPath();
translateYAnimation1.PathGeometry = animationPath1;
translateYAnimation1.Duration = TimeSpan.FromSeconds(6);
translateYAnimation1.Source = PathAnimationSource.Y;
translateYAnimation1.AutoReverse = false;

Storyboard.SetTargetName(translateYAnimation1, "AnimatedRope1");
Storyboard.SetTargetProperty(translateYAnimation1, new PropertyPath(TranslateTransform.YProperty));

//Create Storyboard containing and applying the animation

//animationSB.RepeatBehavior = RepeatBehavior.Forever;
animationSB.Children.Add(translateXAnimation1);
animationSB.Children.Add(translateYAnimation1);

animationSB.AutoReverse = false;

故事板是用另一种方法启动的

我正在windows 8.1N上开发带有.Net 4.5.1c的桌面应用程序。

您应该替换以下行：

lineSegments1.Points.Add(new Point(LeftRope.ActualWidth, LeftRope.ActualHeight));

与

结果表明，如果不为PathFigure指定起始点，它会自动关闭该地物，即连接点集合中的最后一个点和第一个点

pathFigure1.StartPoint = new Point(LeftRope.ActualWidth, LeftRope.ActualHeight);
