Keyboard Function

So I designed this code for arrow down

var to=0

stage.addEventListener(KeyboardEvent.KEY_UP, fl_KeyboardDownHandler_2);

function fl_KeyboardDownHandler_2(event:KeyboardEvent):void

{

to=1 ; gotoAndPlay(6)

}

My question, How do I modify this code so I can gain input from Alphabet. Because I tried

var to=0

stage.addEventListener(KeyboardEvent.KEY_A, fl_KeyboardDownHandler_2);

function fl_KeyboardDownHandler_2(event:KeyboardEvent):void

{

to=1 ; gotoAndPlay(6)

}

But It Doesn't Works

Correct answer Ned Murphy

If you look up the KeyboardEvent class you can see the list of constants that it supports. KEY_A (et al) are not.

What you need to do is check the character code of the key that was pressed to determine if action is to be taken.

stage.addEventListener(KeyboardEvent.KEY_UP, checkKey);

function checkKey(evt:KeyboardEvent):void {
trace(evt.charCode) // use this to find the codes - comment out normally

if(evt.charCode == 97){ // for the letter A

to=1 ;

gotoAndPlay(6);

}
}
