// 享元动作
var FlyWeight = {
    moveX : function ( x ) {
        this.x = x;
    },
    moveY : function ( y ) {
        this.y = y;
    }
};
// 人物移动方法
var Player = function ( x ,y ,c ) {
    this.x = x;
    this.y = y;
    this.color = c;
};
Player.prototype = FlyWeight;
Player.prototype.changeC = function ( c ) {
      this.color = c;
};
// 精灵移动方法
var Spirit = function ( x ,y ,r ) {
    this.x = x;
    this.y = y;
    this.r = r;
};
Spirit.prototype = FlyWeight;
Spirit.prototype.changeR = function ( r ) {
    this.r = r;
};
// 创建人物
var player = new Player( 5 , 6 , ‘red‘ );
console.log ( player );
player.moveX( 6 );
player.moveY( 5 );
// 创建精灵
var spirit = new Spirit( 7 , 5 , 5 );
console.log (spirit );
spirit.moveX( 6 );
spirit.moveY( 5 );
spirit.changeR( 5 );
