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);
