How to extend EventEmitter?

ooh! ooh!... I learned a new thing!  :D

DisplayObject.prototype = Object.create(EventEmitter.prototype);

If you follow the prototype chain on a DisplayObject you will see the EventEmitter interface 

 

 

__proto__EventEmitter

_eventsundefined

addListeneron(event, fn, context)

constructorEventEmitter()

emitemit(event, a1, a2, a3, a4, a5)

listenerslisteners(event, exists)

offremoveListener(event, fn, context, once)

onon(event, fn, context)

onceonce(event, fn, context)

removeAllListenersremoveAllListeners(event)

removeListenerremoveListener(event, fn, context, once)

setMaxListenerssetMaxListeners()

 

So, you should be able to use a DisplayObject as a dispatcher.

Or you can just do this...

var myEventEmitter = Object.create(Object.getPrototypeOf(Object.getPrototypeOf(new PIXI.DisplayObject())))

It's too tiring.Easier sources to correct. Just EventEmitter not in public. I wonder why the authors hid...

We didn't hide it, it is EventEmitter3 (https://github.com/primus/eventemitter3). Just use it in your module. We expose it in the next version so that it is easier to access, but you can just use the module yourself if you want.

 

If you extend any of the Pixi display objects then you will have an emitter anyway though. Anything that extends DO is an emitter.

I use the Google translator, which distorts the speech. I didn't mean that You hide using eventemitter3.
I am saying that if you don't add so -
 
(function(f){if(typeof exports==="object"&&typeof module!=="undefined"){module.exports=f()}else if(typeof define==="function"&&define.amd){define([],f)}else{var g;if(typeof window!=="undefined"){g=window}else if(typeof global!=="undefined"){g=global}else if(typeof self!=="undefined"){g=self}else{g=this}g.PIXI = f()}})(function(){var define,module,exports;return (function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);var f=new Error("Cannot find module '"+o+"'");throw f.code="MODULE_NOT_FOUND",f}var l=n[o]={exports:{}};t[o][0].call(l.exports,function(e){var n=t[o][1][e];return s(n?n:e)},l,l.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o<r.length;o++)s(r[o]);return s})({1:[function(require,module,exports){(function (global){require('./polyfill');var core = module.exports = require('./core');//core.EventEmitter = require('eventemitter3'); <<<<<<<<<<<<<<core.extras = require('./extras');core.filters = require('./filters');core.interaction = require('./interaction');core.loaders = require('./loaders');core.mesh = require('./mesh');core.loader = new core.loaders.Loader();Object.assign(core, require('./deprecation'));global.PIXI = core;}).call(this,typeof global !== "undefined" ? global : typeof self !== "undefined" ? self : typeof window !== "undefined" ? window : {})},{"eventemitter3":11,"./core":29,"./deprecation":78,"./extras":85,"./filters":102,"./interaction":117,"./loaders":120,"./mesh":126,"./polyfill":130}],2:[function(require,module,exports){
 
I can't import it to my code. And he needed me for a single custom model.
