动画对象

## 方法

### [Object Animation.export()](/miniprogram/dev/api/ui/animation/Animation.export)

导出动画队列。**export 方法每次调用后会清掉之前的动画操作。**

### [Animation Animation.step(Object object)](/miniprogram/dev/api/ui/animation/Animation.step)

表示一组动画完成。可以在一组动画中调用任意多个动画方法，一组动画中的所有动画会同时开始，一组动画完成后才会进行下一组动画。

### [Animation Animation.matrix()](/miniprogram/dev/api/ui/animation/Animation.matrix)

同 [transform-function matrix](https://developer.mozilla.org/en-US/docs/Web/CSS/transform-function/matrix)

### [Animation Animation.matrix3d()](/miniprogram/dev/api/ui/animation/Animation.matrix3d)
