为什么在DoubleAnimation之后无法修改TranslateTransform3D的OffsetX？

Question

我的代码在这里，运行此代码后我无法再编辑TranslateTransform3D的偏移属性：

                DoubleAnimation doubleAnimationX =
                    new DoubleAnimation(x,
                                        new Duration(TimeSpan.FromSeconds(second)));
                DoubleAnimation doubleAnimationY =
                    new DoubleAnimation(y,
                                        new Duration(TimeSpan.FromSeconds(second)));
                DoubleAnimation doubleAnimationZ =
                    new DoubleAnimation(z,
                                        new Duration(TimeSpan.FromSeconds(second)));
                                                     translate.BeginAnimation(TranslateTransform3D.OffsetXProperty, doubleAnimationX);
                                                     translate.BeginAnimation(TranslateTransform3D.OffsetYProperty, doubleAnimationY);
                                                     translate.BeginAnimation(TranslateTransform3D.OffsetZProperty, doubleAnimationZ);

TranslateTransform3D派生自Freezable。您的翻译在动画后被冻结，这使其不可变。
