Simple Chat application sample code
Hi Folks,
I was trying out this sample code from the e-book: 'Learning Flash Media Server 3'. I think I have followed everything, from code to setup, for what was mentioned for this code, yet it's not working. Instead of seeing a 'Text Area', 'Input Text' and a 'Button' I am seeing a blank swf and there are no complier errors or anything. I am not sure what is wrong, I hope someone can advise. I am using FMS 3.5 and the following are the code and instructions for the sample code:
Follow these steps to create the application:
1. Open a new Flash file (ActionScript 3.0) and save it as TextSO.fla.
2. Open the Library panel (press Ctrl+L (Windows) or Command+L (Mac OS)) and
drag a TextArea, InputText, and Button component into the Library. Save the file
again.
3. Open a new ActionScript file and save it as TextSO.as.
4. Enter the script in Example 4-3 and resave the file.
package
{
import fl.controls.TextArea;
import fl.controls.Button;
import fl.controls.TextInput;
import flash.display.Sprite;
import flash.events.SyncEvent;
import flash.events.NetStatusEvent;
import flash.events.MouseEvent;
import flash.net.SharedObject;
import flash.net.NetConnection;
public class TextSO extends Sprite
{
private var button:Button;
private var text_so:SharedObject;
private var nc:NetConnection;
private var textArea:TextArea;
private var textInput:TextInput;
private var rtmpGo:String;
private var good:Boolean;
public function TextSO ()
{
//Set up UIs
textArea=new TextArea();
textArea.setSize (200,300);
textArea.move (20,20);
addChild (textArea);
textInput=new TextInput();
textInput.move (20,330);
addChild (textInput);
button=new Button();
button.width=50;
button.label="Send";
button.move (125,330);
button.addEventListener (MouseEvent.CLICK,sendMsg);
addChild (button);
//rtmpGo = "rtmp://192.168.0.11/basicSO";
rtmpGo = "rtmp:/basicSO";
nc = new NetConnection( );
nc.connect (rtmpGo);
nc.addEventListener (NetStatusEvent.NET_STATUS,doSO);
}
private function doSO (e:NetStatusEvent):void
{
good=e.info.code == "NetConnection.Connect.Success";
if (good)
{
//Set up shared object
text_so=SharedObject.getRemote("test",nc.uri,false);
text_so.connect (nc);
text_so.addEventListener (SyncEvent.SYNC,checkSO);
}
}
private function checkSO (e:SyncEvent):void
{
for (var chng:uint; chng<e.changeList.length; chng++)
{
switch (e.changeList[chng].code)
{
case "clear" :
break;
case "success" :
trace (text_so.data.msg);
break;
case "change" :
textArea.appendText (text_so.data.msg + "\n");
break;
}
}
}
private function sendMsg (e:MouseEvent):void
{
text_so.setProperty ("msg",textInput.text);
textArea.appendText (textInput.text + "\n");
}
}
}
The above are the instructions and code and I have done all of them. I have also placed a folder callded 'basicSO' in the 'Flash Media Server 3.5\applications' folder. I am not sure why it's not working. I hope someone can advise. Thanks.
