本文示範如何使用 **Aspose.Slides for Java** 建立簡單的動畫並管理其順序。

## **新增動畫**
建立一個矩形形狀，並套用在點擊時觸發的淡入效果。

```java
static void addAnimation() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 100, 100);

        // 淡入效果。
        slide.getTimeline().getMainSequence().addEffect(
                shape, EffectType.Fade, EffectSubtype.None, EffectTriggerType.OnClick
        );
    } finally {
        presentation.dispose();
    }
}
```

## **存取動畫**
從投影片時間軸取得第一個動畫效果。

```java
static void accessAnimation() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 100, 100);
        slide.getTimeline().getMainSequence().addEffect(
                shape, EffectType.Fade, EffectSubtype.None, EffectTriggerType.OnClick);

        // 取得第一個動畫效果。
        IEffect effect = slide.getTimeline().getMainSequence().get_Item(0);
    } finally {
        presentation.dispose();
    }
}
```

## **移除動畫**
從序列中移除動畫效果。

```java
static void removeAnimation() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 100, 100);
        IEffect effect = slide.getTimeline().getMainSequence().addEffect(
                shape, EffectType.Fade, EffectSubtype.None, EffectTriggerType.OnClick);

        // 移除效果。
        slide.getTimeline().getMainSequence().remove(effect);
    } finally {
        presentation.dispose();
    }
}
```

## **序列動畫**
加入多個效果並示範動畫發生的順序。

```java
static void sequenceAnimations() {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        IAutoShape shape1 = slide.getShapes().addAutoShape(ShapeType.Rectangle, 50, 50, 100, 100);
        IAutoShape shape2 = slide.getShapes().addAutoShape(ShapeType.Ellipse, 200, 50, 100, 100);

        ISequence sequence = slide.getTimeline().getMainSequence();
        sequence.addEffect(shape1, EffectType.Fly, EffectSubtype.Bottom, EffectTriggerType.OnClick);
        sequence.addEffect(shape2, EffectType.Fly, EffectSubtype.Bottom, EffectTriggerType.OnClick);
    } finally {
        presentation.dispose();
    }
}
```
