Hi all,
I have this code (see below) for a scrolling text box. I would like to add to it that if the user presses or holds down the down arrow key on the keyboard, (and if possible if the user scrolls with the mouse wheel) the scroll should work too. I have tried a number of ways including adding it as a listener, a variable and just a plain on function but it has not worked. No matter what I try, the player does not seem to recognize the key press. My file is over 13 mb and this is my first post so I'm not sure if I can upload it. If you need to see it, I'll email it to you.
The only thing is that it has to be compatible with AS1.
Thanks!

Here is my original code: see below for my latest attempt to get the key and mouse wheel working.
CODE
txt.setMask(mask)
scrollbar.onMouseDown = function() {
if (this.hitTest(_root._xmouse, _root._ymouse) && txt._height>mask._height) {
this.startDrag(false, scrollbarBG._x, scrollbarBG._y, scrollbarBG._x, scrollbarBG._height-this._height)
txt.onEnterFrame = scrollThumbs;
dragging = true
}
};
scrollbar.onMouseUp = function() {
stopDrag()
dragging = false
delete this.onEnterFrame;
};
function scrollThumbs() {
var funkyVar = -this._parent.scrollbar._y*(((this._height-this._parent.scrollbar._height)/(this._parent.scrollbarBG._height-this._parent.scrollbar._height))-1)
this.Y = (funkyVar-this._y)*.2;
this._y += this.Y;
if(Math.abs(funkyVar-this._y)<1 && !dragging){
delete this.onEnterFrame
}
}
Here is my latest attempt:
CODE
txt.setMask(mask);
scrollbar.mouseWheelEnabled;
scrollbar.onMouseDown = function() {
if (this.hitTest(_root._xmouse, _root._ymouse) && txt._height>mask._height) {
this.startDrag(false,scrollbarBG._x,scrollbarBG._y,scrollbarBG._x,scrollbarBG._height-this._height);
txt.onEnterFrame = scrollThumbs;
dragging = true;
}
}
var keyListener:Object = new Object();
keyListener.onKeyDown = function() {
var keyCode = Key.getCode();
if (keyCode == Key.DOWN) {
this.txt.scroll++;
}
else if (keyCode == Key.UP) {
this.txt.scroll--;
scrolling = true;
}
};
Key.addListener(keyListener);
Key.addListener(keyListener_obj);
scrollbar.onMouseUp = function() {
stopDrag();
dragging = false;
delete this.onEnterFrame;
};
function scrollThumbs() {
var funkyVar = -this._parent.scrollbar._y*(((this._height-this._parent.scrollbar._height)/(this._parent.scrollbarBG._height-this._parent.scrollbar._height))-1);
this.Y = (funkyVar-this._y)*.2;
this._y += this.Y;
if (Math.abs(funkyVar-this._y)<1 && !dragging) {
delete this.onEnterFrame;
}
}
