Extend Problome

[mirage29]

I create a class extend Sprite.

 

game.createClass('spriteAnimations','Sprite',{ss:{    x:0,    y:0},init: function() {    this._super();    console.log(this.ss)},go: function() {    this.ss.x = 1;},

and do this

 

var a1 = new game.spriteAnimations();a1.go();var a2 = new game.spriteAnimations();

why a2.ss.x also changed ?

The "createClass" method uses "extend" to create a new class and it'll assign properties of the passed object, so "Object properties" are shared between all class instances.

When I do this code:

 

game.createClass('Panda', 'Sprite', {

texture: 'panda.png',

myObject: { myObjectProperty: 10 },

 

init: function(x, y) {

this.position.set(this.myObject.myObjectProperty, y);

this.addTo(game.scene.stage);

},

 

update: function() {

this.position.set(this.myObject.myObjectProperty, this.y);

},

 

changeMyObject: function () {

   this.myObject.myObjectProperty = 300;

}

});

 

game.createScene('Main', {

init: function() {

var sprite = new game.Panda(100, 100);

sprite.changeMyObject();

var sprite = new game.Panda(300, 300);

var sprite = new game.Panda(500, 500);

}

});

 

It's not changing myObject.myObjectProperty on any of the other instances--it only changes the instance on which I called the changeMyObject member function.

 

Am I misunderstanding your question?
