actionscript-3 - Array & TransitionManager 的问题

Question

我需要有关我的 Array 函数的帮助。我正在尝试为网站创建标题，但它只是显示的第一个字母：

这是我的代码：

import fl.transitions.*;
import fl.transitions.easing.*;

var textArray:Array=["W","e","l","c","o","m","e"];

var tformat:TextFormat = new TextFormat();
tformat.color=0x0000CC;
tformat.font="Arial";
tformat.size=40;

var XPosition:Number=100;
var YPosition:Number=12;
var setPosition:Number=36;

function beginPlacement() {        
    var textfield:TextField = new TextField();
    textfield.text=textArray.shift();
    textfield.setTextFormat(tformat);
    var clip:MovieClip=new MovieClip ;
    clip.addChild(textfield);
    clip.x=XPosition;
    clip.y=YPosition;
    addChild(clip);
    var transManager:TransitionManager=new TransitionManager(clip);
    transManager.startTransition({type:Photo, direction:Transition.IN, duration:.3, easing:None.easeNone});
    transManager.startTransition({type:Zoom, direction:Transition.IN, duration:.3, easing:Elastic.easeOut});

    transManager.addEventListener("allTransitionsInDon e", tComplete);
    XPosition=+ XPosition+setPosition;
}

function tComplete(e:Event):void {
    if (textArray.length>0) {
        beginPlacement();
    }
}

beginPlacement();
