Creating EasyKeyboard class Part 3
Today we will add the ability to add listeners to keyboard by specifying key names instead of keycodes.
This way, well be able to set a key listener to the "A" key, for example, by simply passing "A" as one of the values to one of the methods of EasyKeyboard, instead of sending the key code of the key.
To know which name corresponds to which key, well need to add an array keyLabels in EasyKeyboard.as which contains names for all the keys. The index of each element in this array corresponds to the keys key code:
Now create a new function called addEasyListener. The parameters are the same as in addListener, except for the first one.
Instead of receiving keyCode, we receive a string keyName value. Then, in the function, we check which key code belongs to the specified key by looping through the array. If no match is found, then throw an error. If everything went smoothly, then simply call addListener() method with all the same parameter values as we received, and keyCode set to what weve calculated:

If you go to main.as now, you can call the addEasyListener to add keyboard listeners this way:
keyboard = new EasyKeyboard(stage);
keyboard.addEasyListener("A", function() { trace("Down"); }, function() { trace("Up"); } );
// LINE ABOVE EQUALS TO: keyboard.addListener(65, function() { trace("Down"); }, function() { trace("Up"); });

Creating EasyKeyboard class Part 13
Today well further improve the abilities to remove listeners.
The removeListener() function works fine now, but theres a slight problem with removing TimedListeners. The issue is in the Timer, which doesnt stop working even after the listener was "removed". Aside from just removing it from the listeners array, we also need to reset and nullify the timer inside the listener.
You can witness the bug yourself if you create a timed listener and a key listener which removes the timed listener, then try to hold the key which triggers the timed event. If you remove the listener during the delay, youll see that the code dispatches the timed event one more time before stopping.
Lets fix this. Update the removeListener() function:
Now well add a function which removes all the listeners at once. Right now we have one called kill(), but it didnt actually remove all the listeners from the array - it just stops listening to the keyboard as a whole.
The removeAllListeners() method will loop through all listeners and remove them one by one, also taking care of timers the same way like in removeListener:
We should also call this function in kill():
So, to remove all the listeners, the user simply writes:

keyboard = new EasyKeyboard(stage);
keyboard.addEasyTimedListener("A", 1000, function() { trace("Key A is pressed!!") }, true, "key1");
keyboard.addEasyListener("S", function () { keyboard.removeListener("key1"); trace("Listener for A key removed!"); } );
Lets fix this. Update the removeListener() function:
/**
* Remove a single listener.
* @paramlistenerId Id of the listener, which is specified as String when the listener is created.
*/
public function removeListener(listenerId:String):void {
for (var i:int = listeners.length - 1; i >= 0; i--) {
if (listeners[i].id == listenerId) {
if (listeners[i] is TimedListener) {
listeners[i].delayTimer.reset();
listeners[i].delayTimer = null;
}
listeners.splice(i, 1);
break;
}
}
}
Now well add a function which removes all the listeners at once. Right now we have one called kill(), but it didnt actually remove all the listeners from the array - it just stops listening to the keyboard as a whole.
The removeAllListeners() method will loop through all listeners and remove them one by one, also taking care of timers the same way like in removeListener:
/**
* Remove all listeners. IMPORATNT: If you are removing the EasyKeyboard object as a whole, use the kill() method.
*/
public function removeAllListeners():void {
for (var i:int = listeners.length - 1; i >= 0; i--) {
if (listeners[i] is TimedListener) {
listeners[i].delayTimer.reset();
listeners[i].delayTimer = null;
}
listeners.splice(i, 1);
}
}
We should also call this function in kill():
/**
* Call this before nullifying the class instance to remove all the listeners.
*/
public function kill():void {
removeAllListeners();
st.removeEventListener(KeyboardEvent.KEY_DOWN, kDown);
st.removeEventListener(KeyboardEvent.KEY_UP, kUp);
st.addEventListener(Event.ENTER_FRAME, frame);
}
So, to remove all the listeners, the user simply writes:
keyboard.removeAllListeners();
