Variable scope inside module.

[momenimum]

Hi I have a very basic question.  If I want variables to remain scoped to its module what is the best way to do it?  So the below example I want every class created inside the module to be able to see "score".  Right now I use game.score, I can also use global scope with window.  But is there a better way?

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

game.addAsset('screen.png');

game.score = 0; //I want everything in the module to see this
game.hiscore = 0; //I want everything in the module to see this

game.createClass('PreLoader', 'Loader', { ... //This class sees game.score 

game.createScene('Title', { ... //This class sees game.score 

game.createScene('Main', { .. //This class sees game.score

You can just do it like this:

game.module(
    'game.main'
)
.body(function() {
    
var score = 0;

game.createScene('Main', {
    init: function() {
        console.log(score); // 0
    }
});

});

Because the "score" variable is defined with var keyword inside the module, it won't be visible to any other modules, but will be visible to all classes inside that module.

It's not good idea to create variables into root of game object, because you might overwrite something important.

Thanks for the advice!

Useful topic. 

What's the advice for playing music globally? I set it up a global variable like this, and start playing it inside the Main scene(I don't think I it will play if I do it outside the scene), but when I switch scenes, the music stops.

@Wolfsbane If you add this to your config, audio should play thru switching scenes:

game.config = {
    name: 'Test',
    audio: {
        stopOnSceneChange: false //Add this
    },
.......
