as3 dynamic index change for added objects on stage

I have added some backgrounds on 开发者_JS百科stage and then on top of that adding another background and all these are movieclips.

At some time i have to remove the backgrounds and then it should be added but here problem am facing is the background become coming front.

so is there any function like send to back or bring to frond based on the movie clip names.

You want to experiment with :

setChildIndex(object, z-value)

This set the depth of the object on the stage.

swapChildren (object1, object2)

This exchange the position of two objects on the stage.

• setChildIndex
• swapChildren
• swapChildrenAt
• addChildAt

---

Use addChildAt(index);
