Egret
入口文件
Main.ts，清空createGameScene里面的方法，里面是所有场景的起点
protected createGameScene(): void {}
添加背景
var bg:egret.Shape = new egret.Shape();
bg.graphics.beginFill( 0x336699 );
bg.graphics.drawRect( 0, 0, this.stage.stageWidth, this.stage.stageHeight );
bg.graphics.endFill();
this.addChild(bg);
添加文字
var tx:egret.TextField = new egret.TextField();
tx.text = "I'm Jack, I will use Egret create a fantasy mobile game!";
tx.size = 32;
this.addChild( tx );
添加事件
var tx: egret.TextField = new egret.TextField();
tx.text = "I'm Jack, I will use Egret create a fantasy mobile game!";
tx.size = 32;
tx.touchEnabled = true;//记得打开该对象的事件监听，所有对象默认都是不开启事件监听的，为了性能
tx.addEventListener(egret.TouchEvent.TOUCH_TAP
, function (evt: egret.TouchEvent): void {
tx.textColor = 0x00ff00;
}, this);
this.addChild(tx);
除了运用匿名函数，还可以这样添加事件
tx.touchEnabled = true;
tx.addEventListener( egret.TouchEvent.TOUCH_TAP, this.touchHandler, this );
private touchHandler( evt:egret.TouchEvent ):void{
var tx:egret.TextField = evt.currentTarget;
tx.textColor = 0x00ff00;
}
简单安装
最简单的引入方案，引入核心egret.js在页面中进行开发

逻辑文件main.js
class Main extends egret.DisplayObjectContainer {
constructor() {
super();
this.addEventListener(egret.Event.ADDED_TO_STAGE, this.onAddToStage, this);
}
onAddToStage(event) {
let textfield = new egret.TextField();
this.addChild(textfield);
textfield.textColor = 0xff0000;
textfield.text = 'hello world';
}
}
window['Main'] = Main;
egret.runEgret();
