需要关于如何为我正在创建的游戏正确设计层次结构的建议[关闭]

Question

所以我正在创建一个小游戏（以前从未这样做过），但它引起了我的注意并让我好奇，所以我在这里。

我正在尝试为游戏中的对象设计层次结构。

关于我目前拥有的一些物品。

/* this is the basic object - every object in game will have that */
var fnObject = function (node){
    this.nNode = node || '';
    this.id = '';
    this.sType = 'pc'/*pc,npc,physics,obstacle*/;
    this.oPosition = {
        marginTop : 0,
        marginLeft : 0
    };
    /*
    * and more properties. 
    * */
}
/* not all objects will have those */
var fnPhysics = function(){
    this.iFriction = '';
    this.iAcceleration = '';
    this.iGravity = '';
    this.iWind = '';
    this.iIncline  = '';
    this.iSpeed = 1;
    this.iMoveDistant = 5;
    /*
     * and more properties. 
     * */
}

/* Only objects that can move will have those */
var fnControls = function (){
    this.fnGetMvDist = function (){
        //..
    }
    this.fnDoMove = function(){
        //..
    };
    this.fnMoveRight = function(){
        //..
    }
}

/* not all objects will have those */
var fnStats = function(){
    this.hp = 100;
    this.manaLeft = 100;
    this.livesLeft = 5;
    /*
     * and more properties. 
     * */
}

我怎样才能从中构建出良好的层次结构。我的意思是有些对象不会拥有所有这些，有些会。

谢谢

听起来您正在寻找 JS 没有语法的 OOP 类继承。有几种方法可以模拟这一点（google JS OOP），这只是实现它的一种方法：

var fnPhysics = function(){
    var fnObjectInstance = new fnObject();
    fnObjectInstance.iFriction = '';
    fnObjectInstance.iAcceleration = '';
    fnObjectInstance.iGravity = '';
    fnObjectInstance.iWind = '';
    fnObjectInstance.iIncline  = '';
    fnObjectInstance.iSpeed = 1;
    fnObjectInstance.iMoveDistant = 5;
    return fnObjectInstance;
}
