emoveListener (Key.removeListener method)
public static removeListener(listener:Object) : Boolean
Removes an object previously registered with Key.addListener().
Parameters
listener:Object - An object.
Returns
Boolean - If the listener was successfully removed, the method returns true. If the
listener was not successfully removed (for example, because the listener was not on the
Key objects listener list), the method returns false.
Example
The following example moves a movie clip called car_mc using the Left and Right arrow keys.
The listener is removed when you press Escape, and car_mc no longer moves.
var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
switch (Key.getCode()) {
case Key.LEFT :
car_mc._x -= 10;
break;
case Key.RIGHT :
car_mc._x += 10;
break;
case Key.ESCAPE :
Key.removeListener(keyListener);
}
};
Key.addListener(keyListener);
RIGHT (Key.RIGHT property)
public static RIGHT : Number
The key code value for the Right Arrow key (39).
Example
The following example moves a movie clip called car_mc a constant distance (10) when you
press the arrow keys. A sound plays when you press the Spacebar. Give a sound in the library a
linkage identifier of horn_id for this example.
var DISTANCE:Number = 10;
var horn_sound:Sound = new Sound();
