FlxSignalExample.hx

import flixel.util.FlxSignal;

// for signals that don't need data, use FlxSignal
var signal = new FlxSignal();
// for signals that need data, use FlxTypedSignal with the correct function type
var stringSignal = new FlxTypedSignal<String->Void>();

function noParamCallback() {
  trace('Dispatched void event');
}

function showTextCallback(value:String) {
  trace(value);
}


//Registering the callbacks
signal.add(noParamCallback);
stringSignal.add(showTextCallback);
stringSignal.add((x)->{trace(x + " Not so good");});

//Sending out the event
stringSignal.dispatch('Hello World'); //Prints Hello World and also 'Hello World Not so good'
signal.dispatch(); //Prints Dispatched Event
