I NEED TO INPROVE THE CODE ON A MOVIECLIP, TO CONTROL ITS PLAYING SPEED!!

Hi!

I am using this code on a movieClip to make it go from a certain frame to another (backwards or forward) depending on a global variable value. I set the global variable value by pressing buttons.
It works great!

Now: I need to control the playing speed of the movieClip, just by changing a value number directly on the code.
I believe that a 'setInterval' will work, but I don't know exactly where or how.

Can you help me?

Thanks!
Alejandro


CODE:
=============================
// This one goes on the root frame 1. It sets the global variable.
_global.destframe=1

//This one goes on the movieClip that plays backwards or forward, depending on the global variable value.
onClipEvent (enterFrame) {
      if (this._currentframe<_global.destframe) {
            this.nextFrame();
      } else if (this._currentframe>_global.destframe) {
            this.prevFrame();
      }
}
==============================

You can use setInterval but you don't need to - in fact its better not to as setIntervals can easily get out sync with the frame update.

I'd also move your destframe property out of the global scope - otherwise you'll only ever be able to control one movieclip.

A simple solution might look like this...

CODE:
=============================
// this goes on the first frame of the movieclip
destframe = 1;
speed = 1; // higher = faster, lower = slower
frameNumber = 1;

function onEnterFrame () :Void
{
     if (_currentframe < destframe) {
          frameNumber += speed;
     } else if (_currentframe > destframe) {
          frameNumber -= speed;
     }
  trace( frameNumber );
     gotoAndStop( Math.round( frameNumber ) );
}
=============================
