The key code value for the Left Arrow key (37).
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();
horn_sound.attachSound("horn_id");
var keyListener_obj:Object = new Object();
keyListener_obj.onKeyDown = function() {
switch (Key.getCode()) {
case Key.SPACE :
horn_sound.start();
break;
case Key.LEFT :
car_mc._x -= DISTANCE;
break;
case Key.UP :
car_mc._y -= DISTANCE;
break;
case Key.RIGHT :
car_mc._x += DISTANCE;
break;
case Key.DOWN :
car_mc._y += DISTANCE;
break;
}
};
Key.addListener(keyListener_obj);
_listeners (Key._listeners property)
public static _listeners : Array [read-only]
A list of references to all listener objects registered with the Key object. This property is
intended for internal use, but may be useful if you want to ascertain the number of listeners
currently registered with the Key object. Objects are added and removed from this array by
calls to the addListener() and removelistener() methods.
Example
The following example shows how to use the length property to ascertain the number of
listener objects currently registered to the Key object.
var myListener:Object = new Object();
myListener.onKeyDown = function () {
Key 355
