Keyboard toggling

Hello again,

I am working on a new game with actionscript 3 and was coming up with some complications.

I am very used to actionscript 2.0 and I've been trying to force feed this new script and learn as much as possible.

Now for the question. I have a Keyboard event setup like this.

Code:

---

stage.addEventListener(KeyboardEvent.KEY_DOWN, guyMove);
stage.addEventListener(KeyboardEvent.KEY_UP, guyStop);

function guyMove(event:KeyboardEvent):void {
        if(event.keyCode == 39) {
        trace("right");
        }
        if(event.keyCode == 40) {
        trace("down");
        }
        if(event.keyCode == 37) {
        trace("left");
        }
        if(event.keyCode == 32) {
        trace("space");
        }

}
function guyStop(event:KeyboardEvent):void {
        if(event.keyCode == 39) {
        trace("right");
        }
        if(event.keyCode == 40) {
        trace("down");
        }
        if(event.keyCode == 37) {
        trace("left");
        }
        if(event.keyCode == 32) {
        trace("space");
        }

}

It actually took me a little while to get that working in some fashion. :rolleyes: But it wasn't acting the way I wanted. When I press and hold a key, it repeats the guyMove function as if I held down a key when I was typing. It would run once, and moments later, run constantly.

I was kind of looking to get a toggle effect going. So it would trace once when I press, and once when I release. Or even simpler if I could combine into one function and actually trace the press and release without the repeating press trace if I hold the key down.

In as2.0 I would usually use an

Code:

---

onEnterFrame() {
if(Key.isDown(Key.LEFT) {
//do something
}
}

---

That would usually work fine, it would do what I want when I pressed it in an enterFrame fashion, and stop when I release the key.

ANy suggestions?

Thanks

You can still do something like that.

PHP Code:

---

stage.addEventListener (KeyboardEvent.KEY_DOWN, guyMove);
stage.addEventListener (KeyboardEvent.KEY_UP, guyStop);
var kCode:int;
function guyMove (event:KeyboardEvent):void
{
    kCode = event.keyCode;
    event.currentTarget.removeEventListener (KeyboardEvent.KEY_DOWN, guyMove);
    addEventListener (Event.ENTER_FRAME,ef);
}
function ef (e:Event):void
{
    if (kCode == 39)
    {
        trace ("right");
    }
    if (kCode == 40)
    {
        trace ("down");
    }
    if (kCode == 37)
    {
        trace ("left");
    }
    if (kCode == 32)
    {
        trace ("space");
    }
}
function guyStop (event:KeyboardEvent):void
{
    removeEventListener (Event.ENTER_FRAME,ef);
    event.currentTarget.addEventListener (KeyboardEvent.KEY_DOWN, guyMove);
}

************EDITED**********************
I am starting to understand it better, thanks you.

I wanted to know something else as well, :P.

If I wanted to make it recognize when you are pressing more than one thing, that wouldn't work, would it? I'm pretty sure it will only recognize one key press at a time.

I was thinking of setting up different functions for each key that may be pressed, and keep the guyMove function listener active all the time. So if I pressed right it would go to the moveRight function. Then if I pressed spacebar, it would go to moveSpace function.

Do you think that would work?

I actually found the answer to that last question, and now I have a problem with the walls MC.

What happens is, I put a few MCs inside that walls MC
, but when I get to a certain number of them, my code stops working. I can't figure out why for the life of me... I've moved it around to see if it was the placement. But it just doesnt work with a certain number of MCs... Would there be some kind of confusion with the childAt() function I'm using???

Thanks again,
~Bill Ludwig

P.S. I attached the fla to show you what I am talking about...

OMG, I figured it out. I've been messing with it all day, and figured out its a screw up in my "falling" code. So nevermind.

I figure I'll just spend some solid time on some of these problems before resorting to the forums.

Thanks again for all of the help so far!!!!!

Much obliged,
~Bill Ludwig
