referencing stage

Recommended Posts

Hi guys,

 

I have a problem with referencing the stage. Maybe it's  just a JS problem.

My problem lies in the Player.prototype.loaded_normal_animations method. The this.stage reference is gone.

function Player(pixie_stage){  this.stage = pixie_stage;  console.log(this.stage);  this.iMovementDirectionX = 0;  this.iMovementDirectionY = 0;  this.iMovementSpeed = 10;}Player.constructor = Player;Player.prototype = new Object();Player.prototype.load_assets = function(){  var assetsToLoader = [ "data/banshee/normal.json"];    var loader = new PIXI.AssetLoader(assetsToLoader);  loader.onComplete = this.loaded_normal_animations  loader.load();}Player.prototype.loaded_normal_animations = function(){    var normal_animations = [];    normal_animations.push(PIXI.Texture.fromFrame("normal1.png"));    normal_animations.push(PIXI.Texture.fromFrame("normal2.png"));    this.playerSprite = new PlayerShip(normal_animations);    this.stage.addChild(this.playerSprite);    this.playerSprite.position.x = 400;    this.playerSprite.position.y = 500;}

Regards, Alex

loader.onComplete = this.loaded_normal_animations
 
I think this would lead to the function being bound to the window, though I'm not sure. Try this:
 
loader.onComplete Player.prototype.loaded_normal_animations.bind(this);

 

 

Your solution is correct :) the event will have the context of the AssetLoader since the callback is called like so: `this.onComplete` within the AssetLoader instance. If you console.log(this) inside your load callback you will see the context is not what you thought. Lewis's solution should fix your issue
