Loader in Pandajs 2

[lars]

Hello everyone

I´m having some issues with the Loader in Pandajs 2

When i do the following:

 this.loader.onStart = this.setGame.bind(this);
 this.loader.onComplete = this.loadingGame.bind(this);
 this.loader.start();

    Everything is just fine:

But when I try to make a onProgress the onProgress does not response:

 this.loader.onStart = this.setGame.bind(this);
 this.loader.onProgress = this.processGame.bind(this);
 this.loader.onComplete = this.loadingGame.bind(this);
 this.loader.start();

I can see it, and trace it in the Loader.js class :

onProgress: function() {
 //console.log(this.percent);
//if (this.barFg) this.barFg.scale.x = this.percent / 100;
    }

Her is a simple implementation I done:

game.module(
    'game.start'

)

.require(
     'game.assets'

 )


.body(function() {

    game.createScene('Start', {
        backgroundColor: '#5ca282',

        init: function() {
            
         
  this.loader = new game.Loader();             
            
 this.loader.onStart = this.setGame.bind(this);
 this.loader.onProgress = this.processGame.bind(this);
 this.loader.onComplete = this.loadingGame.bind(this);
 this.loader.start();

  }, //END init

          setGame: function() {
           console.log('started'); 
        },
        
          processGame: function() {
           console.log('percent'); 
        },
        
      
        

        loadingGame: function() {

            document.getElementById('loading').style.display = "none";

            this.startContainer = new game.Container().addTo(this.stage);


            if (!/Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent)) {
                this.mytastatur = new game.Sprite('tastatur').addTo(this.startContainer);





            } else {

                this.mytastatur = new game.Sprite('uden-tastatur').addTo(this.startContainer);

            }

            this.mytastatur.position.x = game.system.width / 2 - this.mytastatur.width / 2;
            this.mytastatur.position.y = 0;
            this.mytastatur.interactive = true;
            this.mytastatur.click = this.mytastatur.tap = this.changeScene.bind(this, "Main");

        },


        changeScene: function(go) {


            game.system.setScene(go);
            var playbg = game.audio.playMusic('bb', true);
            game.audio.setVolume(playbg, 0.2);

        },




    }) //END Start



});

Anybody knows what wrong with onProgress on the Loader.

Are you sure you are loading files with the loader?

If you don't have anything to load, onProgress will not be called.

And heres the file that starting the game with the loader:

 

assets.js

[lars]

I have tried with a panda 2 update version from: https://github.com/ekelokorpi/panda-engine/tree/develop/src

And tried the following: 

game.module(
    'game.main'
)
.body(function() {

game.addMedia('baggrund_level1.png','bb');

    
game.createScene('Main', {
    backgroundColor: '#666',

    init: function() {


   console.log('im started');
  this.loader = new game.Loader();
 this.loader.onStart = this.setGame.bind(this);
 this.loader.onProgress = this.setPercentGame.bind(this);
 this.loader.onComplete = this.loadingGame.bind(this);
 this.loader.start();



        
    },

       setGame: function() {
           console.log('Started'); 
        },

         setPercentGame: function() {
           console.log('percent'); 
        },

        loadingGame: function(){
            
        var sprite = new game.Sprite('bb');
        sprite.addTo(this.stage);
 }

 
});

});

With the same result. No response from the onProgress listener.

Default loader will load that baggrund_level1.png file before you enter to your Main scene. So that's why there is nothing to load, and onProgress will not be called.

If you want to change the default loader, you can inject game.Loader class, or make new class from it and then change the default loader class into the new one in your config.

Like this:

game.createClass('MyLoader', 'Loader', {
    onStart: function() {},
    onProgress: function() {},
    onComplete: function() {}
});

game.config = {
    system: {
        loader: 'MyLoader'
    }
};

 

[lars]

Hello Enpu

So f...... nice to have you back :-) . It´s working now. Thanks a lot ...  

Heres how I did (just a dummy, with some stolen parts), and put a reference in the config.js file as you said :-) :

game.config = {
    system: {
        width: 1024,
        height: 768,
        center: true,
        scale: true,
        loader: 'MyLoader'
    }
};

And the dummy loader: 

game.module(
    'game.main'
)


.require(
    'game.assets'
)

.body(function() {

    this.bar;

    game.createClass('MyLoader', 'Loader', {
        onStart: function() {

            this.bar = new game.Graphics();

            this.bar.beginFill('#ccc');
            this.bar.drawRect(0, 0, 260, 40);

            this.bar.x = game.system.width / 2 - (260 / 2);
            this.bar.y = game.system.height / 2 - (40 / 2);
            this.bar.scale.x = this.percent / 100;
            this.bar.addTo(this.stage);

        },

        onProgress: function() {

            console.log(this.percent);
            //console.log(this.sprite.x);
            this.bar.scale.x = this.percent / 100;

        },

        onComplete: function() {

            game.system.setScene('Main');
        }
    });

    game.createScene('Main', {
        backgroundColor: '#666',

        init: function() {

            console.log('opo');


        }


    });





});

Only one thing:

If I try to preload mp3 like:

 game.addMedia('sound/soundwaterdrop.*', 'water');

Errror: Uncaught Unsupported file format *

or

 game.addMedia('sound/soundwaterdrop.mp3', 'water');

Error: Unsupported file format mp3

 

This happens in the updated 2.0 version: 

https://github.com/ekelokorpi/panda-engine/tree/develop/src

Have been trying to look around in the Loader.js file ... but ... :-)

[lars]

 Ehh .... ok. No support of MP3 :-)

[enpu]

You can modify the list of supported audio formats in game.Audio.formats array (though i recommend to use m4a/ogg)

[zakhov]

game.addMedia('assetfile','assetfilenname')

  So we only use game.addMedia for all asset loading from now on? I used game.addAsset and game.addAudio previously last time I used Panda JS 2.0.

I'm going through the latest panda develop version and just trying to wrap my head around some of the changes.

Something weird happened when I tried loading m4a/ogg audio files though, I enabled retina/hires and it loads all the image and image@2x assets correctly, including fonts. But for some reason it's looking for [email protected]/ogg for audio files as well. Is this a bug?

game.addMedia('sound/sound_sfx.m4a','sound_fx');

Cheers

Nevermind, fixed it myself. I just added a workaround to check for the audio formats at the getfile funciton in loader.js and ignore them even if retina | hires is enabled.

Hi @zakhov,

Sorry for late reply, this definitely was a bug and has been now fixed. Thanks!

Cool. I would've made a pr but I thought my method was a bit too hack-ish. Good to hear that you've fixed it though. Cheers
