1.onFrame事件 - 移動攝像機：

< html >
     < head >
         < title >onFrame - Move camera </ title >
         < object id ="SGWorld" classid ="CLSID:3a4f91b1-65a8-11d5-85c1-0001023952c1" style ="visibility:hidden;height:0 " ></ object >
         < script type ="text/javascript" >

         var time = 5 * 1000 ; // move for 5 sec.

         function Init()
        {
            SGWorld.AttachEvent( " onFrame " , onFrame);

            SGWorld.Navigate.JumpTo(SGWorld.Creator.CreatePosition( - 100.0 , 40.0 , 13000000 , 3 , 0 , - 85 ));
            setTimeout( function () { SGWorld.DetachEvent( " onFrame " , onFrame); }, time);
        }

         function onFrame()
        {

             var pos = SGWorld.Navigate.GetPosition();

            pos.X += 0.5 ;
            pos.Y -= 0.2 ;

            SGWorld.Navigate.SetPosition(pos);

        }

         </ script >
     </ head >
     < body onload ="Init();" >
     </ body >
</ html >

2.onFrame事件 - 移動對象：

< html >
     < head >
         < title >onFrame - Move objects </ title >
         < object id ="SGWorld" classid ="CLSID:3a4f91b1-65a8-11d5-85c1-0001023952c1" style ="visibility:hidden;height:0 " ></ object >
         < script src ="abspath.js" type ="text/javascript" ></ script >
         < script type ="text/javascript" >


         var model = null ;
         var time;

         function Init()
        {
            time = new Date();
            SGWorld.AttachEvent( " onFrame " , onFrame);

             var pos = SGWorld.Creator.CreatePosition( - 122.38050 , // x
                                                   37.62331 ,   // y
                                                   40.0 ,       // height
                                                   3 ,          // height type
                                                   297.0 ,      // yaw
                                                   15.0 ,       // pitch
                                                   0 ,          // roll
                                                   0            // dist
                                                  );

            model = SGWorld.Creator.CreateModel(pos, toAbspath( " data/747.xpc " ), 0.2 );

            model.Attachment.AutoDetach = false ;

            SGWorld.Navigate.FlyTo(model);
        }

         function onFrame(elapsedTime)
        {
             // move object with speed of 400km/h
             var distToMove = ( 400 * 1000 / 3600 ) * ( new Date().getTime() - time.getTime()) / 1000 ;

            model.Position = model.Position.Move(distToMove, model.Position.Yaw + 0.1 , model.Position.Pitch);
            time = new Date();
        }

         </ script >
     </ head >
     < body onload ="Init();" >
     </ body >
</ html >

3.onLButtonDown事件：

< html >
     < head >
         < object id ="SGWorld" classid ="CLSID:3a4f91b1-65a8-11d5-85c1-0001023952c1" style ="visibility:hidden;height:0 " ></ object >
         < script type ="text/javascript" >

         var globe = null ;
         var pos    = null ;
         var popup, popup2;

         function Init()
        {

            SGWorld.AttachEvent( " onLButtonDown " , onLButtonDown);
            SGWorld.AttachEvent( " onRButtonDown " , onRButtonDown);
            popup2 = SGWorld.Creator.CreatePopupMessage()
            popup2.InnerText = " Left click on the terrain to get the coordinates at cursor position. Right click to finish. " ;
            SGWorld.Window.ShowPopup(popup2);
        }

         function onLButtonDown(flags, x,y)
        {
             var ret = SGWorld.Window.PixelToWorld(x, y);

            popup = SGWorld.Creator.CreatePopupMessage( " onLButtonDown event " , "" , x, y);

            popup.InnerText = (ret == null ) ? " Screen coordinate hit the sky " : " Screen coordinates ( " + x + " , " + y + " ):\nTerrain coordinate:\nX: " + ret.Position.X + " \nY: " + ret.Position.Y;

            SGWorld.Window.ShowPopup(popup);

             return true ; // event was processed by the client. return false to allow additional processing of the event.
        }

         function onRButtonDown(flags, x,y)
        {

            SGWorld.DetachEvent( " onLButtonDown " , onLButtonDown);
            SGWorld.DetachEvent( " onRButtonDown " , onRButtonDown);

             if (popup)
                SGWorld.Window.RemovePopup(popup);
             if (popup2)
                SGWorld.Window.RemovePopup(popup2);

             return true ; // event was processed by the client. return false to allow additional processing of the event.
        }

         </ script >
     </ head >
     < body onload ="Init();" >
     </ body >
</ html >

4.屏蔽右鍵彈出菜單：

< html >
     < head >
         < title >Preventing right popup </ title >
         < object id ="SGWorld" classid ="CLSID:3a4f91b1-65a8-11d5-85c1-0001023952c1" style ="visibility:hidden;height:0 " ></ object >
         < script type ="text/javascript" >

         function Init()
        {
            SGWorld.AttachEvent( " onRButtonDown " , onRButtonDown);
            SGWorld.AttachEvent( " onRButtonDblClk " , onRButtonDblClk);

            SGWorld.Window.ShowMessageBarText( " This sample shows how to disable the default right context menu. Double right-click to re-enable " , 3 );
        }

         function onRButtonDown(flags, x,y)
        {

             return true ; // Tell TE that the OnRButtonDown event was processed by the client
        }

         function onRButtonDblClk(flags, x,y)
        {
            SGWorld.DetachEvent( " onRButtonDown " , onRButtonDown);
            SGWorld.DetachEvent( " onRButtonDblClk " , onRButtonDblClk);
            SGWorld.Window.HideMessageBarText();

            alert( " Right click is now enabled " );

             return false ;
        }

         </ script >
     </ head >
     < body onload ="Init();" >
     </ body >
</ html >

5.onTerraExplorerMessage事件：

< html >
     < head >
         < title >onTerraExplorerMessage event </ title >
         < object id ="SGWorld" classid ="CLSID:3a4f91b1-65a8-11d5-85c1-0001023952c1" style ="visibility:hidden;height:0 " ></ object >
         < script type ="text/javascript" >

         function Init()
        {
            SGWorld.AttachEvent( " onTerraExplorerMessage " , onTerraExplorerMessage);

             var label = SGWorld.Creator.CreateTextLabel(SGWorld.Creator.CreatePosition( - 71.00425 , 42.36081 , 100 ),
                                                       " Click here to get the name of the airport " ,SGWorld.Creator.CreateLabelStyle());

             var msg = SGWorld.Creator.CreateMessage( 0 , " Logan International " , 0 );
            label.Message.MessageID = msg.ID;

            SGWorld.Navigate.JumpTo(label);
        }

         function onTerraExplorerMessage(messageId, senderNodeId)
        {
             var message = SGWorld.Creator.GetObject(messageId);
             var senderNode = SGWorld.Creator.GetObject(senderNodeId);
            senderNode.Text = message.Text;
        }

         </ script >
     </ head >
     < body onload ="Init();" >
     </ body >
</ html >
