listerners and functions

[Gekke_Hollander]

I stil;l haven't been able to grasp the whole concept. I have a mc that I want to flip on a keyUp... on a keyDown I want it to flip and move... But with this code it will flip and move no matter what...

keyListener = new Object();
keyListener.onKeyUp = function() {
	Flip();
	this.onKeyDown = function() {
		Flip();
		Move();
	};
};
function Flip() {
	if (_root.snowman._currentframe == 1) {
		if (Key.getCode() == Key.RIGHT) {
			_root.snowman._xscale = 100;
		}
		if (Key.getCode() == Key.LEFT) {
			_root.snowman._xscale = -100;
		}
	}
}
function Move() {
	if (_root.snowman._currentframe == 1) {
		if (Key.getCode() == Key.RIGHT) {
			_root.snowman._xscale = 100;
			_root.snowman.play();
			_root.snowman.x = x_movement;
		}
		if (Key.getCode() == Key.LEFT) {
			_root.snowman._xscale = -100;
			_root.snowman.play();
			_root.snowman.x = -1*x_movement;
		}
	}
}
Key.addListener(keyListener);

Ideas anyone?

Cheers!

i dunno if this will apply to you but movieclips dont need to have an added keyListiner

try

onClipEvent(keyDown)

onClipEvent(keyUp)

onClipEvent(keyPress)

or even

onClipEvent(enterFrame)

then to get the keys try

if(Key.isDown(Key.Down))

try defining your keyDown outside of your keyUp. Also, do you mean the "down" and "up" keys. Or do you really want one function when any key is actually pressed down and a second when that key is released?

Sorry, wasn't to clear on that but yes! I ment the left and right arrow keys... The keyDown function should only work when the button is being held down for a while...

in flash, the keyDown event is simple, any time any key is in the down state, the event is triggered and any associated function is executed. If you want this to only work for specific keys, define them. Also, if you only want the function to start after the key's been "down for a while," you'll have to add some kind of counter:

code:

---

keyListener.onKeyDown = function(){

  if(Key.isDown(Key.RIGHT) || Key.isDown(Key.LEFT))

    counter += 1;

    if(counter > 10){

      Flip();

      Move();

    }

  }

}

---

something like that

Why didn't I think of that

I changed it a bit

keyListener.onKeyUp = function() {
	start_timer = 0;
};
keyListener.onKeyDown = function() {
	if (Key.isDown(Key.RIGHT) || Key.isDown(Key.LEFT)) {
		if (start_timer == 0 || start_timer == undefined) {
			start_timer = getTimer()/1000;
		}
		timer = getTimer()/1000;
		trace(timer-start_timer);
	}
	if (timer-start_timer>0.2) {
                  do etc...

Thanx for that and happy holidays!

Cheers
