Defining array of objects that are defined in the same scope JavaScript

Question

I am working on a small framewok that i received as a school assignment...and I chose to do someting in JavaScript...this is the code that I have until now :

(function (){
//Creating our framework named GM (from game) 
var GM = {

    canvas : null, // the place where all the action happens is the canvas
    context : null, 
    // other functions ...  


    player : {
        frameNr : 0,
        frames : [],
        loaded : new Array(),
        loadedImages : false,

        xCoord : 0,             // current X coordinate of the player
        yCoord : 0,             // current Y coordinate of the player

        speed : 0,              // speed of the moving player

        xDirection : 0,
        yDirection : 0,

        width : 0,
        height : 0,

        // other things related to player
      }
    }

if(!window.$$){window.$$=GM;}//We create a shortcut for our framework, so we can call the methods by $$.method();

})();

I used this tutorial a little bit to see how to get started : http://www.admixweb.com/2009/05/20/how-to-easily-create-a-javascript-framework-part-1/

Anyway...my question is this : I want a way so that whoever is using my framework can add multiple players(with different settings) if he likes...From what i can tell there could be 2 theoretical approaches (i say theoretical, because i don't know if they are doable or not given the current context):

1. To somehow have an array of players in my framework
2. To have some kind of getter that returns a player from the framework....and that player is maybe stored in an array outside the framework...

What do you guys think..what approach is better or doable ?

Thanks

EDIT: Added a field which stores the array of players. This field is on the same level as player in the framework. Code below :

players : {

        array : [],
        length : 0,

        add : function(player){
            this.array.push(player);
            this.length = this.length + 1;
            console.log("+ 1 player");
        },

        animate : function(){

            for (i=0;i<this.length;i++){
                this.array[i].animate();
            }

        }

    }
