这里是什么样子: http://screencast.com/t/4cd1yQJReXtWPF动画沿着正确的路径,但它关在空间
的小船图像是假设跟着你出去图表为它的路径。它确实有效 - 它遵循路径,但是它从错误的地方开始。我无法弄清楚我的动画有什么问题,而且我现在已经多次阅读了代码。应用程序的XAML是非常简单的都是含有内 帆布NAME =“Canvas1”背景中的元素=“黑”
,这画布是 窗口
及以下的子元素是代码,做动画。我知道一个事实,即我喂它的线是正确的。这只是他们的参考点被搞砸了。它应该是Canvas1,但它不是。
NameScope.SetNameScope(this, new NameScope());
MatrixTransform buttonMatrixTransform = new MatrixTransform();
ship1.RenderTransform = buttonMatrixTransform;
this.RegisterName("ButtonMatrixTransform", buttonMatrixTransform);
PathGeometry animationPath = new PathGeometry();
PathFigure pFigure = new PathFigure();
pFigure.StartPoint = new Point(pathnodes.ElementAt<Line>(0).X1, pathnodes.ElementAt<Line>(0).Y1);
PolyLineSegment ls = new PolyLineSegment();
foreach (Line l in pathnodes)
{
ls.Points.Add(new Point(l.X1, l.Y1));
ls.Points.Add(new Point(l.X2, l.Y2));
}
pFigure.Segments.Add(ls);
animationPath.Figures.Add(pFigure);
animationPath.Freeze();
MatrixAnimationUsingPath matrixAnimation =
new MatrixAnimationUsingPath();
matrixAnimation.IsOffsetCumulative = false;
matrixAnimation.PathGeometry = animationPath;
matrixAnimation.Duration = TimeSpan.FromSeconds(5);
matrixAnimation.DoesRotateWithTangent = true;
Storyboard.SetTargetName(matrixAnimation, "ButtonMatrixTransform");
Storyboard.SetTargetProperty(matrixAnimation,
new PropertyPath(MatrixTransform.MatrixProperty));
Storyboard pathAnimationStoryboard = new Storyboard();
pathAnimationStoryboard.Children.Add(matrixAnimation);
pathAnimationStoryboard.Begin(this);
谢谢!
