Kirupa scrollpane doesnt work

programming flash
1

I’ve tried various tutorials on this site and different versions for doing the same thing, but I can’t get any of them to work. I have Flash CS3.

This tutorial from kirupa doesnt work yet it’s the one i’d like the most to work as it’s everything i have been looking for.

Here’s the code for it:


scrolling = function () {
 var scrollHeight:Number = scrollbg._height;
 var contentHeight:Number = contentMain._height;
 var draggerHeight:Number = dragger._height;
 var maskHeight:Number = maskedView._height;
 //
 var initPosition:Number = dragger._y=scrollbg._y; var initContentPos:Number = contentMain._y;
 var finalContentPos:Number = maskHeight-contentHeight+initContentPos;
 //
 var left:Number = scrollbg._x;
 var top:Number = scrollbg._y;
 var right:Number = scrollbg._x;
 var bottom:Number = scrollbg._height-draggerHeight+scrollbg._y;
 //
 var dy:Number = 0;
 var speed:Number = 10;
 var moveVal:Number = (contentHeight-maskHeight)/(scrollHeight-draggerHeight);
 //
 dragger.onPress = function() {
  var currPos:Number = this._y;
  startDrag(this, false, left, top, right, bottom);
  this.onMouseMove = function() {
   dy = Math.abs(initPosition-this._y);
   contentMain._y = Math.round(dy*-1*moveVal+initContentPos);
  };
 };
 dragger.onMouseUp = function() {
  stopDrag();
  delete this.onMouseMove;
 };
 btnUp.onPress = function() {
  this.onEnterFrame = function() {
   if (contentMain._y + speed < maskedView._y) {
    trace(dragger._y + " " + top);
    if (dragger._y <= top) {
     dragger._y = top;
     contentMain._y += speed;
    } else {
     contentMain._y += speed;
     dragger._y -= speed / moveVal;
    }
   } else {
    dragger._y = top;
    contentMain._y = maskedView._y;
    delete this.onEnterFrame;
   }
  };
 };
 btnUp.onDragOut = function() {
  delete this.onEnterFrame;
 };
 btnUp.onMouseOut = function() {
  delete this.onEnterFrame;
 };
 btnDown.onPress = function() {
  this.onEnterFrame = function() {
   if (contentMain._y - speed >finalContentPos) {
    if (dragger._y>=bottom) {
     contentMain._y -= speed;
     dragger._y = bottom;
    } else {
     contentMain._y -= speed;
     dragger._y += speed/moveVal;
    }
   } else {
    dragger._y = bottom;
    contentMain._y = finalContentPos;
    delete this.onEnterFrame;
   }
  };
 };
 btnDown.onRelease = function() {
  delete this.onEnterFrame;
 };
 btnDown.onDragOut = function() {
  delete this.onEnterFrame;
 };
};
scrolling();

I’ve entered the instance names as I should have done, according to the tutorial.

Now all I get is loads of errors:

Guidance, please :slight_smile:
