As3: keyBoard eventListener working slow

Hello mates,


I am trying to move an object on stage with arrow keys. I am using this code

Actionscript Code:

stage.addEventListener(KeyboardEvent.KEY_DOWN, moveCatcher);

function moveCatcher(event:KeyboardEvent):void {

    if(event.keyCode == Keyboard.LEFT && catcher.x >= 0)
        catcher.x -=8;
    else if(event.keyCode == Keyboard.RIGHT && catcher.x < 600)
        catcher.x +=8;
    
}

The problem is that it do not start to move immediately after I press the key and it takes few moments to move. I have uploaded the swf file here http://www.evaic.com/catcher202kkles...oqwnlssewe.swf

Please suggest some solution if you figured out the problem,


Regards :)

You need to detect both key up and down press. Try something like below.

var rightClick:Boolean = false;
var leftClick:Boolean = false;

stage.addEventListener(KeyboardEvent.KEY_DOWN, CatcherMove);
stage.addEventListener(KeyboardEvent.KEY_UP, CatcherNoMove);
stage.addEventListener(Event.ENTER_FRAME, enterFrameHandler);


function CatcherMove(e:MouseEvent):void{
switch(e.keyCode){
case Keyboard.LEFT: leftClick = true; break;
case Keyboard.RIGHT: rightClick = true; break;
}
}


function CatcherNoMove(e:MouseEvent):void{
switch(e.keyCode){
case Keyboard.LEFT: leftClick = false; break;
case Keyboard.RIGHT: rightClick = false; break;
}
}


function enterFrameHandler(e:Event):void{
if(rightClick && catcher.x >= 0) catcher.x -=8;
if(leftClick && catcher.x < 600) catcher.x +=8;
}
