需要关于如何正确设计游戏的层次结构的建议我创建

Question

因此，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，所以在这里。

我想设计游戏内物体的层次结构。

一些关于我到目前为止的对象。

/* 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. 
    * */ 
} 

我怎样才能构建出良好的层次结构。我的意思是有些物体不会有所有这些和一些将。

这听起来像你正在寻找OOP类继承其JS没有语法。有几种方法在这里模拟这种（谷歌JS OOP）只是其中的一个方法去实现它：

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; 
}
