目前我的舞台上有文字,我想登上舞台并停在舞台上的某个位置(97,233.10)。我有点困惑在哪里停止它以及使用什么代码?
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似乎现在返回输出错误:
TypeError: Error #1009: Cannot access a property or method of a null object reference.

在if语句中,我们检查对象是否已超出目标位置,如果有,则停止循环。否则继续递增对象的位置。
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;
}
}

确保信息在舞台上并尝试添加:
