Ⓒegret.DisplayObject 用法

多個物件用程式排列位置

let doc = new egret.DisplayObjectContainer();
doc.addChild(new egret.Shape());
doc.addChild(new egret.TextField());
doc.addChild(new egret.Shape());
doc.addChild(new egret.TextField());
doc.addChild(new egret.Shape());
for (let i = 0, len = doc.numChildren; i < len; i++) {
    let mydo:egret.DisplayObject = doc.getChildAt(i); //多型
    mydo.x = 0;
    mydo.y = 50 * i;
}
