controlling children of sprites

var spriteOne:Sprite = new Sprite();

spriteOne.name="myCircle";

spriteOne.graphics.beginFill(0x999999);

spriteOne.graphics.drawCircle(0,0,100);

var spriteTwo:Sprite = new Sprite();

spriteTwo.addChild(spriteOne);

addChild(spriteTwo);

In as3 you can call sprite directly

spriteOne.alpha=.5;//-----directly---

or

var clip=spriteTwo.getChildByName("myCircle");//----------call by name

clip.alpha=.5;

Sorry, that was a typo (I was typing a simplified example of the code I'm trying to use), but the fixed script still gives me the same error...

import flash.display.Sprite;

var spriteOne:Sprite = new Sprite()

spriteOne.graphics.beginFill(0x999999)

spriteOne.graphics.drawCircle(0,0,100)

var spriteTwo:Sprite = new Sprite()

spriteTwo.addChild(spriteOne)

addChild(spriteTwo)

spriteTwo.spriteOne.alpha = .5

Scene 1, Layer 'Layer 1', Frame 1, Line 11 1119: Access of possibly undefined property spriteOne through a reference with static type flash.display:Sprite.

1. What the lines

spriteTwo.addChild(spriteOne)

addChild(spriteOne)

do is add spriteOne as a child of spriteTwo --> REMOVES spriteOne from spriteTwo --> adds spriteOne as a child to the current scope. In other words sprtieOne IS NOT a child of spriteTwo any more.

2. DisplayObjectConteiner's children ARE NOT PROPERTIES. Thus, you cannot use dot notation. This is what the error says. To get children of an objects you need to use getChildAt(), getChildIndex() or getChildByName() methods.

if you did not remove spriteOne from sprtieTwo, the code could be:

spriteTwo.getChildAt(0).alpha = .5;

or, if it has many children:

spriteTwo.getChildAt(spriteTwo.getChildIndex(spriteOne)).alpha = .5;

Yep, as ned said, you're adding/putting spriteOne inside spriteTwo.

you should try spriteOne.addChild(spriteTwo); //here you'll be adding sprite2 to sprite1.

Is the same as when you say addChild(spriteOne); You could also say this.addChild(spriteOne); or stage.addChild(spriteOne); It's the same thing.

But I'm not so sure that this is the only problem in your code.
