Skyline从5.1升级版本到6.5的常见接口变化问题

function flyto(thisa)
{
    var thisid = thisa.id;    
    var thisb=IInformationTree.GetObjectEx(thisid,"");
    if(thisb.ObjectType=="21")//动态路径Route
     {
        thisb.Play();
     }
     else {
        thisid=IInformationTree.GetTerraObjectID(thisid);  
        IPlane.FlyToObject(thisid,0);  
     }
}

function flyto(thisa)
{
    var thisid = thisa.id;
    var sg = CreateSGObj();   
    var thisb = sg.ProjectTree.GetObject(thisid);
     if(thisb.ObjectType=="34")//动态路径Route升级为Presentation
     {
        thisb.Play(0);
     }
     else {
         sg.Navigate.FlyTo(thisid,0);
     }
}
