Actionscript 3D how to develop 3d sprite

I am developing a flash application required me to have a rotational sprite object cycling around the 3D space. I saw a MovieClip has a z-index that can be used as z coordinates in 3d space but 开发者_StackOverflowcouldn't find it in sprite object.

How to I get around with that.

Here is some sample code on how to create a 3D scene in Flash with sprites:

3D can get very complicated so it is best to play with an example.

When you say "but couldn't find it in sprite object." what do you mean? Adobe's documentation of the Sprite class lists the z property in it's property list (http://help.adobe.com/en_US/AS3LCR/Flash_10.0/flash/display/Sprite.html). Perhaps you need to click "Show Inherited Public Properties" to see it? Anyway, the following pseudo-code might be helpful:

var sprite:Sprite = new Sprite();
addChild(sprite);

addEventListener(Event.ENTER_FRAME, onEnterFrame);

protected function onEnterFrame(e:Event):void
{
    sprite.z += (mouseX - sprite.z) * 0.2;
}

Good luck!
