TextField上的隐式强制错误(Error of implicit coercion on a TextField)

 我认为我有最常见的动作错误。在下面的代码中，我有一个MovieClip与一些TextFields里面，我想动画他们。当我把类分配给MovieClip我得到这个错误1118: Implicit coercion of a value with static type Object to a possibly unrelated type flash.text:TextField. 。 当我trace孩子时，我得到[Object TextField]并且代码工作正常，如果我将它放在第一帧并将其应用于动态文本，那么为什么当我尝试将此代码应用于MovieClip的孩子时出现此错误？ 
 
 是否有机会忘记import任何必要的图书馆？ 
 
 我已经使TextFields动态化了，我嵌入了字符并为动画设置了反锯齿。 
 
package AScripts
{

import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
import com.greensock.*;
import com.greensock.easing.*;
import flupie.textanim.*;

public class TextFade extends MovieClip {
    private var child : Object;

    public function TextFade( )     
    {
        /*    for (var i : int = 0; i < numChildren; i++  )  {
              child = getChildAt( i );
              trace( child );  
        */
            child = getChildAt( 0 );
            var txtanim:TextAnim = new TextAnim( child ); // <-- Error
                            /* TextAnim expects a TextField as argument */
            txtanim.mode = TextAnimMode.RANDOM;
            txtanim.split = TextAnimSplit.WORDS;
            txtanim.effects = myEffect;
            txtanim.start();
    }
    function myEffect( block:TextAnimBlock ) : void
    {
        TweenLite.to( block , .5 , {alpha : 0 , delay : Math.random( ) * 1 } );
    }   
  }
}
 
 更新：我提出了建议更改并工作。 
 
import flash.text.*;
private var child : TextField;
child = getChildAt( i ) as TextField;

I think i have the most common actionscript error.In the code below i have a MovieClip with some TextFields inside and i want to animate them.When i assign the class to the MovieClip i get this error 1118: Implicit coercion of a value with static type Object to a possibly unrelated type flash.text:TextField.. When i trace the childs i get [Object TextField] and the code works fine if i place it on the first frame and apply it to a Dynamic Text so why i get this error when i try to apply this code to the childs of a MovieClip ?
 
Is there a chance to have forgot to import any necessary library ?
 
I have made the TextFields dynamic,i have embed the characters and set anti-alias for animation.
 
package AScripts
{

import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
import com.greensock.*;
import com.greensock.easing.*;
import flupie.textanim.*;

public class TextFade extends MovieClip {
    private var child : Object;

    public function TextFade( )     
    {
        /*    for (var i : int = 0; i < numChildren; i++  )  {
              child = getChildAt( i );
              trace( child );  
        */
            child = getChildAt( 0 );
            var txtanim:TextAnim = new TextAnim( child ); // <-- Error
                            /* TextAnim expects a TextField as argument */
            txtanim.mode = TextAnimMode.RANDOM;
            txtanim.split = TextAnimSplit.WORDS;
            txtanim.effects = myEffect;
            txtanim.start();
    }
    function myEffect( block:TextAnimBlock ) : void
    {
        TweenLite.to( block , .5 , {alpha : 0 , delay : Math.random( ) * 1 } );
    }   
  }
}
 
UPDATE : I made the suggestion changes and worked.
 
import flash.text.*;
private var child : TextField;
child = getChildAt( i ) as TextField;
