在WPF中翻译变换和旋转

Question

翻译工作正常，但没有轮换，你能帮帮我吗？

TranslateTransform trans = new TranslateTransform();

Pointer.RenderTransform = trans;

DoubleAnimation animX = new DoubleAnimation(fromX, toX, TimeSpan.FromMilliseconds(325));
DoubleAnimation animY = new DoubleAnimation(fromY, toY, TimeSpan.FromMilliseconds(325));

DoubleAnimation rotateBy = new DoubleAnimation(0, 90, TimeSpan.FromMilliseconds(325));

animX.EasingFunction = new SineEase { EasingMode = EasingMode.EaseInOut };
animY.EasingFunction = new SineEase { EasingMode = EasingMode.EaseInOut };

animX.Completed += new EventHandler(myanim_Completed);
trans.BeginAnimation(TranslateTransform.XProperty, animX);
trans.BeginAnimation(TranslateTransform.YProperty, animY);

trans.BeginAnimation(RotateTransform.AngleProperty, rotateBy);

Answer 1

TranslateTransform没有Angle属性。您应该使用TransformGroup：

var group = new TransformGroup();
var trans = new TranslateTransform();
group.Children.Add(trans);
var rotate = new RotateTransform();
group.Children.Add(rotate);

Pointer.RenderTransform = group;

// the rest of the code is fine; only the last line needs fixing:

rotate.BeginAnimation(RotateTransform.AngleProperty, rotateBy);

您还应该考虑使用Storyboard对动画进行分组。
