The Sequence effect plays multiple child effects one after the other, in the order in which they are added.

You can create a Sequence effect in MXML, as the following example shows:

  <mx:Sequence id="WipeRightUp">
    <mx:children>
      <mx:WipeRight duration="1000"/>
      <mx:WipeUp duration="1000"/>
    </mx:children>
  </mx:Sequence>
  
  <mx:VBox id="myBox" hideEffect="{WipeRightUp}">
    <mx:TextArea id="aTextArea" text="hello"/>
  </mx:VBox>

Notice that the <mx:children> tag is optional.

Starting a composite effect in ActionScript is usually a five-step process:

Create instances of the effect objects to be composited together; for example:
```
myFadeEffect = new mx.effects.Fade(target);
```
Set properties, such as duration, on the individual effect objects.
Create an instance of the Sequence effect object; for example:
```
mySequenceEffect = new mx.effects.Sequence();
```
Call the addChild() method for each of the effect objects; for example:
```
mySequenceEffect.addChild(myFadeEffect);
```
Invoke the Sequence effect's play() method; for example:
```
mySequenceEffect.play();
```

The <mx:Sequence> tag inherits all of the tag attributes of its superclass, and adds the following tag attributes:

  <mx:Sequence id="identifier">
    <mx:children>
      <!-- Specify child effect tags --> 
    </mx:children>
  </mx:Sequence>
