how to access my assets in jsdeliver

[m4rk2s 0]

Hi,

i have some assets (on dropbox) that i've found on the internet and i want to have them online like what did @samme on jsdeliver this way do you have any idea on how to do it

        preload: function() {
            game.load.baseURL = 'https://cdn.jsdelivr.net/gh/samme/phaser-examples-assets@v1.0.0/';
            game.load.crossOrigin = 'anonymous';
            game.load.image("bar", "sprites/zelda-life.png")
        }

If you make a GitHub repository you can use 

https://cdn.jsdelivr.net/gh/USERNAME/REPONAME/

I've tested it but it won't work

Hi,

 Phaser way:

            let imageUrl = "https://cloudgames.com/app/img/logo-horizontal.png";

            this.load.crossOrigin = "";
            this.load.image("LOGO", imageUrl);

did not work for me too - all I got was "SecurityError: The operation is insecure.".

But then I found this tutorial: https://webglfundamentals.org/webgl/lessons/webgl-cors-permission.html

and this worked for me:

            var cache = this.cache;
            var img = new Image();
            img.addEventListener('load', function () {

                console.log("***** LOADED ***** ");
                cache.addImage("LOGO", imageUrl, img);

            });
            img.crossOrigin = "";
            img.src = imageUrl;

Now you can create your sprite like this:

var logo = this.game.add.sprite(0, 0, "LOGO");

I think you need 

this.load.crossOrigin = 'anonymous';

An empty value ('') essentially means make no cross-origin requests.

@samme thanks for answer, but are you sure? With Phaser none of "" or "anonymous" work - in both cases texture cannot be used in WebGL. That linked tutorial is using "" and it works (it also works with setting to "anonymous").

In fact, this is image I am trying to load and use: "https://cloudgames.com/app/img/logo-horizontal.png" - it is sponsor logo. It can load & use it only if used  that way I described above (no matter if I set it to "" or "anonymous" , but if I omit this line: img.crossOrigin = ""; I get this error ... which is exactly what that tutorial was about (how to use CORS texture in WebGL)

Now, I am struggling with http x https. If URL for image is https it works, if it is http, then it does not work. Looks like sponsors emulator is returning http, but luckily production looks to return https (I debugged one PIXI game there).

When you're setting an image's crossOrigin property directly, an empty string or any string value besides use-credentials is the same as anonymous. That's why the tutorial code works.

But for Phaser's Loader#crossOrigin, an empty string is the same as false, meaning don't set the crossOrigin property.

The server also has to accept the cross-origin request, but I guess that's not the problem in your case.

So I'm not sure why your two-step method works.  It looks similar to what Phaser is doing in loadImageTag.

@samme - thanks for explanation & help! It works for me now. I tried "anonymous" before without luck, but it was messed with second problem - sever is returning URL link without protokol (like //cloudgames.com/ ....) and if I converted it into absolute URL, it added http (because my dev server is http). But server is returning image only if asked for with https. If I ask for it with correct protokol, then everything works.
