</div>

so I’m trying to create a sound with `this.sound.add` in 1 function, & play it with another function, but for some reason I’m getting `'this.sys.game.globals.model is undefined'`.

I have created a small demo in order to figure this out. Why is the above undefined? Here is the direct link to the `'main project'` : [https://thundros.github.io/sound-test/](https://thundros.github.io/sound-test/) | Here is the direct link to `'Model.js'` : [https://thundros.github.io/sound-test/res/menu-system/Model.js](https://thundros.github.io/sound-test/res/menu-system/Model.js) | Here is the direct link to `'main.js'` : [https://thundros.github.io/sound-test/res/game/js/main.js](https://thundros.github.io/sound-test/res/game/js/main.js) | Here is the direct link to `'sfx.js'` : [https://thundros.github.io/sound-test/res/game/js/sfx.js](https://thundros.github.io/sound-test/res/game/js/sfx.js)

Any help as always is most DEFINITELY appreciated!

Thank you!

Phaser doesn’t define `this.sys.game.globals`, so do you?

I don’t know what it’s supposed to be. But you need something like

```javascript
this.sys.game.globals = { model: {} };

```

There’s already [this.sys.game.registry](https://photonstorm.github.io/phaser3-docs/Phaser.Game.html#registry) though, you can use that.

@samme : I decided to stop using that old code & i created a new code.

i have come up with my own. how do i get it to switch to the sound i want say when i go to the next level?

```javascript
this.LoadAudio = function ( __objData )  

{

    this. __objData =__ objData;

    this. __snd = this.__ objData.sound;
    this. __soundID = this.__ objData.soundID;
    this. __soundData = this.__ objData.soundData;

    if ( typeof ( this.__objData ) !== 'object' ) { return console.error ( 'ERROR :: { Please ensure you are using an `object` for `objectData` & try again } !' ); }

    console.error ( 'Loaded Sound ID' + ' :: ' + this.__soundID );
    console.error ( 'Loaded Sound Data' + ' :: ' + JSON.stringify ( this.__soundData ) );

    this. __sound = this.__ snd.add ( this. __soundID, this.__ soundData );

    return {

        sounds : {

            sound: this.__sound, 
            soundID : this.__soundID, 
            soundData : this.__soundData, 

        }, 

    };

}

this.IsSoundPlaying = function ( __sound )

{

    this. __sound =__ sound;

    return this.__sound.isPlaying;

}

this.PlayAudio = function ( __objData )

{

    this. __objData =__ objData;

    this. __snd = this.__ objData.sound;
    this. __soundID = this.__ objData.soundID;
    this. __soundData = this.__ objData.soundData;

    if ( typeof ( this.__objData ) !== 'object' ) { return console.error ( 'ERROR :: { Please ensure you are using an `object` for `objectData` & try again } !' ); }

    this.__soundPlaying = ( this.IsSoundPlaying ( this.__sound ) );
    console.error ( 'this. __soundPlaying :: ' + this.__ soundPlaying );

    this.StopAudio ( this.__sound );
    this.__sound.play ( );

}

this.StopAudio = function ( __sound )

{

    this. __sound =__ sound;

    if ( typeof ( this.__sound ) !== 'object' ) { return console.error ( 'ERROR :: { Please ensure you are using an `object` for `objectData` & try again } !' ); }

    this.__sound.stop ( );

}

```

the way it is called :

```javascript
// Create & Load our BGM{s}

this.__BGMTrack = [

	'bgMusic', 'lvl1Music', 'lvl1MusicA', 
	'lvl2Music', 

];

this.__BGMData = [

	{ 
		volume : 0.1, loop : true, 
	}, 

	{
		volume : 0.1, loop : true, 
	}, 

	{
		volume : 0.03, loop : true, 
	}, 

	{
		volume : 0.1, loop : true, 
	}, 

];

// Create & Load our sound{s}

this.__SFXTrack = [

	'jumpA', 

];

this.__SFXData = [

	{ 
		volume : 0.1, loop : true, 
	}, 

];

__BGMAudio =__ m.LoadAudio ( {
	sound : this.sound, 
	soundID : this.__BGMTrack [3], 
	soundData : this.__BGMData [3], 
}, 1 );

__m.PlayAudio ( {
	sound : __BGMAudio, 
}, 1 );

/*

__SFXAudio =__ m.LoadAudio ({
	sys : this.sys, 
	sound : this.sound, 
	soundID : this.__SFXTrack [0], 
	soundData : this.__SFXData [0], 
}, 1 );

*/

```

ok, so my code works fine to an extent, but for some reason using multiple  
`'__m.PlayAudio ( )'` calls, it only switches in the game. Not the title screen.

```javascript
this.PlayAudio = function ( __objData )

{

    this. __objData =__ objData;

    this. __snd = this.__ objData.sound;
    this. __soundID = this.__ objData.soundID;

    if ( typeof ( this.__objData ) !== 'object' ) { return console.error ( 'ERROR :: { Please ensure you are using an `object` for `objectData` & try again } !' ); }

    this.__soundPlaying = ( this.IsSoundPlaying ( this.__sound ) );
    console.error ( 'this. __soundPlaying :: ' + this.__ soundPlaying );

    if ( this.IsSoundPlaying ( this.__sound ) === true ) {

        this.StopAudio ( this.__sound );
        this.__sound.play ( this.__soundID );

    }

    else {

        this.__sound.play ( this.__soundID );

    }

}

```

but to no avail.  
I want it to stop the old playing sound & start the new 1.  
for some reason, it’s letting the other sounds play on top of the old sound.

why is it doing this? the function is correct…

ok, so I see what my sound manager is doing. It’s not stopping the 1st playing sound after calling `__m.PlayAudio ( )` twice.  
It should stop the 1st track & play the chosen track.

i did this. it seems to be picking up on the sounds in the game but not the title screen… so the title screen is playing simultaneously with the game sounds. but the game sounds are not playing simultaneously with other game sounds.

all i do is :

```javascript
this.IsSoundPlaying = function ( __sound )

{

	this. __sound =__ sound;

	return this.__sound.isPlaying;

}

```

```javascript
this.PlayAudio = function ( __objData )

{

    this. __objData =__ objData;

    this. __scene = this.__ objData.scene;
    this. __snd = this.__ objData.sound;
    this. __soundID = this.__ objData.soundID;

    console.log ( this.IsSoundPlaying ( this.__snd ) );

    if ( this.IsSoundPlaying ( this.__snd ) === true ) {

        this.StopAudio ( this.__snd );

        this.__snd.play ({
            seek : 0, 
        });

    }

    if ( this.IsSoundPlaying ( this.__snd ) === false ) {

        this.__snd.play ({
            seek : 0, 
        });

    }

}

```

then when i call :

```javascript
__m.PlayAudio ( {
    scene : this.__scene, 
    sound : __BGMAudio, 
    soundID : __BGMAudio.soundID, 
}, 1 );

```

more than once in different scenes, it doesn’t stop the currently playing track like it’s supposed to. It only plays the 1st in-game sound then when the player jumps, it cancels the level’s theme & switches to jumping.  
it shouldn’t switch to jumping. it should allow jumping to play along side the level’s theme, but themes should not be able to play on top of other themes.

I don’t know. I’m not sure how it’s supposed to work.

`IsSoundPlaying()` looks wrong to me. I don’t understand why it’s assigning to `this.__sound`.

If you just want to play one sound at a time in some context, I think the core logic is

```javascript
var current, next;

if (current.isPlaying) {
  current.stop();
  this.sound.remove(current);
}

current = next;

current.play();

```

If you want to play several sounds at one time in some context, then there’s no need to store the current one playing.

It has to be an actual [Sound](https://photonstorm.github.io/phaser3-docs/Phaser.Sound.BaseSound.html), not the key itself.
