Hi DomenicoGemoli, 

You can establish a connection between creatives, instantiating the LocalConnect component programmatically, implementing the following code (It works for AS2 and AS3, V2 components): 

//Creating a parent 

import com.google.ads.studio.localconnect.LocalConnectParent; 
var childChannelNames:Array = ["my child"]; 
var parentConnect:LocalConnectParent =new LocalConnectParent(childChannelNames); 
parentConnect.connect(); 

//Creating a child 

import com.google.ads.studio.localconnect.LocalConnectChild; 
var childConnect:LocalConnectChild = new LocalConnectChild("my child"); 
childConnect.connect(); 


This way you can establish the connection when you need it. 

If you want to detect when the creatives has connected use the code below: 
 
function conectFunction(e:StudioEvent):void{ 

trace("Connection established"); 

} 

localConnectComponent.addEventListener(StudioEvent.CONNECT, conectFunction); 


Also you can send and receive data between your creatives, using this code: 

//Send data 
// Setup: localConnectComponent is the instance name of the Local Connect component on the stage.

import com.google.ads.studio.localconnect.LocalConnectWrapper;
var dataObject:Object={message:"Start synced animation!"};

// Send data to all connected components.
localConnectComponent.sendData(dataObject);


//Set up listeners to handle sent data:

import com.google.ads.studio.events.StudioEvent;

trace("Message was " + event.data.message);

// If the dataObject referred to in the above "send" example is sent, event.data.message will be "Start synced animation!". 

if (event.sender == LocalConnectWrapper.PARENT_NAME && event.data.message == "Start synced animation!") { 

trace("Message was sent from the parent"); 

// Start your synced animation here. 

}
