不能在代码背后同时动画两个动画
本文关键字：动画 两个 代码 背后 不能 | 更新日期: 2023-09-27 18:05:14
我认为类简化了很多时间，而且代码变得更有条理。我正在创建一个类，以便用代码动画对象。我正在创建的类使您能够使用主动画。如果我想让一个对象基于这个类动画化，我会输入:
// Instantiate an object from animatinos class
MyStoryboards.Animations a = new MyStoryboards.Animations(this);
// add animations to storybaord
a.addAnimation(brdBorder, MyStoryboards.Animations.animProperty.TranslateX, 150, TimeSpan.FromSeconds(4));
a.addAnimation(brdBorder, MyStoryboards.Animations.animProperty.Rotate, 150, TimeSpan.FromSeconds(4));
a.addAnimation(brdBorder, MyStoryboards.Animations.animProperty.Opacity, 0, TimeSpan.FromSeconds(4),1,TimeSpan.FromSeconds(1), a.getBackEase());
// start animations
a.beginAnimation();
// delete all animations
a.removeAllAnimations();
和I，当我执行时，对象旋转，它的不透明度动画。但它的翻译并不是动画。如果我去掉:
a.addAnimation(brdBorder, MyStoryboards.Animations.animProperty.Rotate, 150, TimeSpan.FromSeconds(4));
则对象brdBorder将沿着x轴平移，它的不透明度也将被动画化。我刚刚完成构建这个类，我似乎不能弄清楚什么时候我能够同时动画几个东西，什么时候我不能。大多数时候，我都能给两个或更多的东西做动画。
让我提供类的代码，我认为经过一些修改它会很有帮助。它的功能在于你可以让几个属性动起来，但它的功能不在于有时你可能想要同时让两个东西动起来。无论如何，下面是代码:

我认为这门课可以节省很多时间，而且非常有用。试试吧。或者我可能需要在单独的线程中运行这些方法以便同时为几个东西动画?
为什么不能同时工作?很简单，如果你选择一个操作作为目标属性，类将覆盖保存在目标的RenderTransform中的现有操作，完全忽略任何现有的转换，所以如果你想要一个转换操作将被改变，如果你然后开始旋转，转换将消失。
