AssetLoader call onComplete only once

[turbosqel]

I have problem with using assetloader ,because when I refresh page it is not calling onComplete function .

[GoodBoyDigital]

Thanks for the heads up! Seems to be the same issue as this: #13
Which browser are you using? Does the issue exist across all of your browsers? Thanks!

[turbosqel]

Chrome 25 and Firefox 19 , it might be 'hasLoaded' problem :
var texture = PIXI.Texture.fromImage(filename);
if(!texture.hasLoaded)

but it should be probably : if(!texture.baseTexture.hasLoaded)

Im not sure , just hinting

[GoodBoyDigital]

I agree, will take a poke around later today. Annoyingly I cant seem to recreate the issue on my current setup, would you mind testing the fix for me once its complete?

[turbosqel]

Now Im 99% sure that this is an issue because this code works fine :

if (PIXI.Texture.fromImage("asset/shadow.png").baseTexture.hasLoaded) {
LoadComplete();
} else {
var loader = new PIXI.AssetLoader(["asset/1.jpg", "asset/js.png","asset/shadow.png"]);
loader.onComplete = LoadComplete;
loader.load();
}

Ok , I'll download latest when You fix it and give You feedback !

i think that cause is order of code.
img.onload=func after img.src="url" or,
img.src="url" after img.onload=func <- this was "from cache".

[turbosqel]

yeah , but it must work anyway, cache or download :)

[GoodBoyDigital]

Quick test :)

If you swap these two lines around in the PIXI.Texture.fromImage function:

image.src = imageUrl;
baseTexture = new PIXI.BaseTexture(image); 

like this:

baseTexture = new PIXI.BaseTexture(image);
image.src = imageUrl; 

does that fix the issue?

[piayo]

baseTexture = new PIXI.BaseTexture(image);
image.src = imageUrl; 

and,

PIXI.BaseTexture = function(a) {
    this.height = this.width = 0;
    if (this.source instanceof Image)
        if (this.source.width) //"complete" property is buggy its always "true"

I think it is ok.

[turbosqel]

Nope , but I was right about "hasLoaded" param . Please look at code :
https://github.com/GoodBoyDigital/pixi.js/blob/master/src/pixi/loaders/AssetLoader.js#L84

Texture object dont have property "hasLoaded" so (!texture.hasLoaded) will be always true and it try load and never end , but it should skip it . There must be :
if(!texture.textureBase.hasLoaded){...

and at end of function :
if(this.loadCount == 0){this.onAssetLoaded();};

This solved problem .

[GoodBoyDigital]

Oh yes! you are absolutely correct 👍 Great catch!
piayo does turbosqel's solution work for you? Thanks both!

[turbosqel]

Thats a pain of js . Im moving from as3 to js and no strong type can cause big headaches :) btw any plans of adding solid color graphic rects ?

[GoodBoyDigital]

I hear that! I come from as3 land too :)
I do have plans for solid rects, they will probably be the first primitive I make.

[turbosqel]

yeah , thats very usefull , just like starilng quads . I'll try also implement this in Your lib : http://turbosqel.pl/relativestarling/

[GoodBoyDigital]

nice one 👍

[fernandodrumond]

Hello!

@turbosqel 's answer worked for me, just note that the code should be:

if(!texture.baseTexture.hasLoaded)

Copy and paste on the other code will give you an error. ;)

Please, let me know when this fix is added to the repo, so I can go back to work with the most recent version.

By the way, awesome library! Thanks a lot!

[turbosqel]

Dont forget to add :
if(this.loadCount == 0){this.onAssetLoaded();};

on botton of "load()" function , because loader wont call onComplete without it

[fernandodrumond]

One more thing, the function PIXI.AssetLoader.prototype.onAssetLoaded

Should have

this.loadCount--;

replaced by

if(this.loadCount > 0){ this.loadCount--; }

Otherwise the comparison to 0 will return false if all assets are loaded (this.loadCount will be -1).

I was experiencing this problem on Firefox and it would only work after cleaning the cache.

[turbosqel]

it should not happen , since loadCount is taken from toLoad array length . So it should loop and shift always to 0 .

[fernandodrumond]

On the code I had, there was a call to this.loadCount--; on the beginning of the method onAssetLoaded(), so a call to it with this.loadCount == 0 would make this.loadCount evaluate to -1.

[GoodBoyDigital]

Should be all good now gents :)

[fernandodrumond]

Works fine for me now! Thanks!
