验证：谁发送，谁接收
Event :

module demo{
    export class myEvent extends egret.Event{
        public static readonly _DEMO_EVENT : string = "_demo_event";
        private _data : ImyEventName = null;
        public constructor( $ty :  string , $data : ImyEventName ){
            super( $ty , false , false );
            this._data = $data;
        }
        public get Data() : ImyEventName{
            return this._data;
        }
    }

    export interface ImyEventName{
        /**发送者*/
        _sender : string;
        _dispatcher : myDispacherEvent;
    }
}

EventDispatcher:

module demo{
    export class myDispacherEvent extends egret.EventDispatcher{
        /**
         * 发送事件
         * @param {string} $ty
         * @param {string} $myName
         */
        public sender( $ty : string , $myName : string ) : void{
            let $event : myEvent = new myEvent(
                $ty,
                {
                    _sender : $myName,
                    _dispatcher : this
                }
            );
            this.dispatchEvent( $event );
        }
    }
}

测试代码：

    private $dispatcher_0 : demo.myDispacherEvent = null;
    private $dispatcher_1 : demo.myDispacherEvent = null;
    /**
     * preload资源组加载完成
     * Preload resource group is loaded
     */
    private onResourceLoadComplete(event: RES.ResourceEvent) {
        if (event.groupName == "preload") {
            this.stage.removeChild(this.loadingView);
            RES.removeEventListener(RES.ResourceEvent.GROUP_COMPLETE, this.onResourceLoadComplete, this);
            RES.removeEventListener(RES.ResourceEvent.GROUP_LOAD_ERROR, this.onResourceLoadError, this);
            RES.removeEventListener(RES.ResourceEvent.GROUP_PROGRESS, this.onResourceProgress, this);
            RES.removeEventListener(RES.ResourceEvent.ITEM_LOAD_ERROR, this.onItemLoadError, this);
            // this.createGameScene();
            this.$dispatcher_0 = new demo.myDispacherEvent();
            this.$dispatcher_0.addEventListener( demo.myEvent._DEMO_EVENT , this.onDemo , this );
            this.$dispatcher_1 = new demo.myDispacherEvent();
            this.$dispatcher_1.addEventListener( demo.myEvent._DEMO_EVENT , this.onDemo , this );

            this.$dispatcher_0.sender( myEvent._DEMO_EVENT , "Aonaufly" );
            this.$dispatcher_1.sender( myEvent._DEMO_EVENT , "Ainy" );
        }
    }

    private onDemo( $e : demo.myEvent ) : void{
        if( $e.type == demo.myEvent._DEMO_EVENT ){
            egret.log(`发送者：${$e.Data._sender}, dispatcher_0 : ${ $e.Data._dispatcher == this.$dispatcher_0 }`);
        }
    }

结果：

Aonaufly 发送的 ， Ainy是不会触发的 ， 切记。。。。。。
