Flash Detect Keyboard Input with Key Listeners

Heres another helpful bit of flash actionscript code to help you on your way with developing dynamic flash content.

 

Key Listeners

Key Listeners allow you to record the input of keys from the keyboard in flash and allow you to peform actions with keys

First you need to setup your key listener as a function as follows:

KeyListener = new Object();
KeyListener.onKeyDown = function() {
if (Key.getAscii() == 13) { // Code for ENTER key
gotoAndPlay(25);
} else if (Key.getAscii() == 8) { // Code for BACKSPACE key
gotoAndPlay(35);
}
}

 

Then either after the function or on another frame where you want the key listender to start simply add this code:

Key.addListener(KeyListener);

 

Detecting if "Any Key" is pressed

this.createEmptyMovieClip("_keyListener",1);
Key.addListener(_keyListener);
_keyListener.onKeyDown=function(){
play();
}
