AS3 Tips of the Day - LocalConnection AS3

AS3' LocalConnection is just the same as in AS2, only differences is the event listeners. This can be useful when it needs to communicate a AS2 to AS3, because we can't loadmovie a AS2 to AS3, or vice versa. There are other ways to use this. Hope my simple example can help others.

Sender:

package {
 import flash.display.*;
 import flash.events.*;
 import flash.net.*;
 
 public class  Sender extends MovieClip {
  private var send_lc:LocalConnection;
  private var params:String = "my name is mykhel";
  public function Sender():void {
   /// instantiate send_lc  
   send_lc = new LocalConnection();
   
   /// should have status event for testing purposes
   send_lc.addEventListener(StatusEvent.STATUS, onStatus);
   
   /// send to receiver a connection id and methods with params
   /// .toString() just to make sure the receiver will be accepting a String
   send_lc.send("connectId", "callBackFunction", params.toString());
  }
  
  /// instantiate rcv_lc  
  private function onStatus(evt:*):void {
            switch (evt.level) {
                case "status":
                    trace("LocalConnection.send() succeeded");
                    break;
                case "error":
                    trace("LocalConnection.send() failed");
                    break;
            }
  }
 }
}

Receiver:

package {
 import flash.display.*;
 import flash.events.*;
 import flash.net.*;
 
 public class  Receiver extends MovieClip {
  private var rcv_lc:LocalConnection;
  public function Receiver():void {
   /// instantiate rcv_lc  
   rcv_lc = new LocalConnection();
   
   /// setting rcv_lc client to this
   rcv_lc.client = this;
   
   /// i put in a enterframe event the connect, i used this in a tandem simultaneous connect
   addEventListener(Event.ENTER_FRAME, function ():void {
    try {
     
     /// rcv_lc connect with connectId (this should be unique id)
       rcv_lc.connect("connecId");
       
    } catch (error:ArgumentError) {
     trace("Can't connect...the connection name is already being used by another SWF");
    }
   });
  }
  
  /// function to be execute passed from LC sender.
  public function changeImage(str:String):void {
   trace("LC CONNECTED. PARAMS: " + str);
  }
 }
}
