动态加载模型

1、    从 Resources 文件夹下加载prefab物体
GameObject  obj;
//prefabname: 不需要后缀名  
obj  = (GameObject)Instantiate(Resources.Load(prefabname));
修改obj的参数
obj .transform.parent=  obj .transform.position =  世界坐标  
obj.name = id;
2、    动态加载对象，动态对象包放在exe同目录的Object文件夹下
GameObject  obj;  if  (!prefabname.Contains(".unity3d"))             prefabname = prefabname + ".unity3d";        string exepath =  System.IO.Directory.GetCurrentDirectory();        string url =  exepath + "/Object/" +  prefabname;  
     DLAsset(url);
  public  IEnumerator DLAsset(string url)    
{          WWW www = new  WWW(url);          yield return www;          obj = (GameObject)Instantiate(www.assetBundle.mainAsset);    
}  
3、    动态加载对象，对象包在web服务器某目录下  string  url;      if (!modelName.Contains(".unity3d"))          fullModName = modelName + ".unity3d";      if (Application.platform == RuntimePlatform.WindowsWebPlayer)    
{           url = Application.dataPath + "/model/" + fullModName;    
}   // 静态加载对象，预制件必须在Resources文件夹下       else if (Application.platform == RuntimePlatform.WindowsEditor)      
{          url = "file://" + Application.dataPath + "/" + fullModName;   }        else// 动态加载对象,动态对象包放在exe同目录的Object文件夹下      
{          url = Application.dataPath + "/Object/" + fullModName;      
}        url = devinforservip+"/jsp/web/model/" + fullModName;        WWW wwwgl = new WWW(url);        yield return wwwgl;        wwwObj.Add(wwwnub, wwwgl);        try      
{           objt = wwwgl.assetBundle.mainAsset;           ModObj.Add(modelName, objt);      
}        catch
       
{            LogInfo = " 获取模型 "  + url+" 出错，或者模型不存在！" ;        
}         obj = (GameObject)Instantiate(objt);         obj.transform.position = new Vector3(x, y, z);         obj.transform.localEulerAngles = new Vector3(rx, ry, 0);         obj.name =  deviceid;         obj.transform.parent = GameObject.FindWithTag(parentid).transform;  
CabDicHS .Add(deviceid, obj);
