如何保存动画更改 [英] How save animation changes

问题描述

例如，当发生点击时，我尝试缓慢地将带有动画的椭圆围绕(0,0)旋转.为此，我在RotateTransform.AngleProperty上使用DoubleAnimation，如下所示:

i try to rotate a ellipse with animation around (0,0) slowly for example when a click occured. for this i use DoubleAnimation on RotateTransform.AngleProperty like this :

DoubleAnimation da = new DoubleAnimation();
da.Duration = new Duration(TimeSpan.FromSeconds(2));
da.To = -50;
RotateTransform rt = new RotateTransform();
rt.BeginAnimation(RotateTransform.AngleProperty, da);
rt.CenterX = ellipse.Width / 2 - ellipse.Margin.Left / 2;
rt.CenterY = ellipse.Height / 2 - ellipse.Margin.Top / 2;
ellipse.RenderTransform = rt;

但是当完成修复时，椭圆的Margin属性不会改变.

我想在动画结束到新位置后动态更改边距.

怎么办?

谢谢.

but when aniamtion finished Margin property of ellipse not change.

i want to dynamically change Margin when animation finished to the new location.

how do it?

thanks.

推荐答案

我没看到问题.属性System.Windos.FrameworkElement.Margin是类型为System.Windows.Thickness的读/写属性；因此您可以自由为其分配新值.计算动画结束后期望的值，并将其分配给您的Ellipse或其他形状:

I don''t see a problem. The property System.Windos.FrameworkElement.Margin is a read/write property of the type System.Windows.Thickness; so you can freely assign a new value to it. Calculate the value you expect to have after the end of animation and assign it to your Ellipse or other shape:
