Question

我是actionscript3的新手，如果有人可以帮助我，我会有一个非常有用的问题。我正在尝试从rss feed xml文件中读取并在文本框中显示它并使框自动滚动的动作脚本，我的问题是文本字段不会循环回来。这是代码：

var RSSLoader:URLLoader = new URLLoader();
var RSSURL:URLRequest = new URLRequest("http://sports.yahoo.com/soccer//rss.xml");
RSSLoader.addEventListener(Event.COMPLETE, RSSLoaded);
RSSLoader.load(RSSURL);
stage.addEventListener(Event.ENTER_FRAME, TextScrollingFunction);

var RSSXML:XML = new XML();

RSSXML.ignoreWhitespace = true;

function RSSLoaded(e:Event):void 

 {

RSSXML = XML(RSSLoader.data);
//trace(RSSXML.toXMLString());
var title:TextField;
var desc:TextField;
var allText:TextField;
title = new TextField();
allText = new TextField();
for(var selectedItems:String in RSSXML.channel.item){

    title.text=(RSSXML.channel.item[selectedItems].title+"\n");
    title.wordWrap = true;
    tfLog.text+=title.text;
    tfLog.wordWrap = true;
    trace(title.text);

}

function TextScrollingFunction(evt:Event)

{

tfLog.x+=3;//the Speed of the srolling Text

if ((tfLog.x + tfLog.width)<0) {
    tfLog.x=stage.stageWidth;

    //remove all the Children from the stage.
    while (tfLog.numChildren > 0) {
        tfLog.removeChildAt(0);
    }
    RSSLoader.load(RSSURL);
}

如果每个装载机工作正常，我想说问题可能是：

...
if (tfLog.x > stage.stageWidth) {
    tfLog.x = -tfLog.width;   //but in case your textfield has a static width
...

或者简单地说：

...
tfLog.x -= 3;
...

actionscript3 rss提供滚动文本
