Egret之自定义事件

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。。。。。。
