Actionscript [Moving Movie Clips using Keyboard]

To capture Keyboard input, Actionscript uses the object "Key". This object listens to Keyboard events such as keydown, keyup, keypress and also returns keycode being pressed.



[putting the script on stage and movie clip's instance name is MC]

Code:


MC.onEnterFrame = function(){
  if (Key.isDown(Key.UP)){
    MC._y-=1;  // moves MC 1 pixel upward... y-axis
  }
}


[putting the script on the movie clip itself ]

Code:


onClipEvent(keyDown){ // keyDown event triggers when a key is pressed
  if(Key.isDown(Key.UP)){
    this._y-=1;// moves this movie clip 1 pixel upward... y-axis
  }
}
