滚动文本字段帮助 as3

scrolling text field help as3

当前收到舞台下的文字,我想上台并停在舞台上的某个位置 (97, 233.10)。我对在哪里停止它以及使用什么代码有点困惑?

addEventListener(Event.ENTER_FRAME, mcInfo);

 function mcInfo (e:Event):void {

//check position of logo
//if inside the stage move left to right
//if outside stage reposition

if (info.x<stage.stageWidth) {
    info.x+=30;
    stop();
    } else {
        //reset position
        info.x=-450;
    }
}

干杯!

当我滚动浏览其余页面时,Flash 现在似乎返回输出错误:

TypeError: Error #1009: Cannot access a property or method of a null object reference.
    at finaldesign_fla::MainTimeline/mcInfo()

确保信息在舞台上并尝试添加:

if(info != null && stage != null)

在if语句中,我们检查对象是否超出了目标位置,如果超出则停止循环。否则继续增加对象的位置。

targetPosition = {x:97, y:233.10};

addEventListener(Event.ENTER_FRAME, mcInfo);

function mcInfo(e:Event) {
   if (info.x >= targetPosition.x) {
      info.x = targetPosition.x;
      removeEventListener(Event.ENTER_FRAME, mcInfo);
   } else {
      info.x += 30;
   }
}
