[TUTORIAL] simple flash movement tutorial (as2.0) part 1

OK this is for people who have learnt event handlers and want to move objects
this is very basic
lets say you have a head (of a mapler) and want to move it

the code will be this

Code:

      onClipEvent (enterFrame) {

          if (Key.isDown(Key.LEFT)) {

              _x--;

          }
 
          if (Key.isDown(Key.RIGHT)) {
 
              _x++;
 
          }
 
          if (Key.isDown(Key.UP)) {
 
              _y--;
 
          }
 
          if (Key.isDown(Key.DOWN)) {
 
              _y++;
 
          }
 
      }

Explanation:
onClipEvent(enterFrame)
this is the event handler
tells it to execute the following from the { to the last }

lines 2 -4 tells it to move in the direction specified depending on which key is down
the other lines are pretty similar

please comment and inform me of any errors
