[atslopes]

Just ran across this cool site,

seems like they used parrallax scrolling does anyone know how to accomplish this in code or after effects.

By the way how are the rollovers done.

hey, atslopes,

I put something together to answer a similar question in another forum.. This (http://www.onebyonedesign.com/junk/plax/parallax.html) is what I came up with.

Basically, you just want to move a forgeground movie clip at twice the speed of a background movieclip..

To get the mouse movement, I used a movieclip only 8 pixels wide (named scrollButton_mc) which I then scaled up to fill the entire stage.. the relative xmouse values, though, will remain -4 through 4 (therefore the background speed will range from -4 -4 and the foreground speed will be -8 - 8).. Here's the entire script:

stop();
scrollButton_mc._alpha = 0;
scrollButton_mc.useHandCursor = false;
// "fg" == "foreground"
// "bg" == "background"
// "lt" == "left"
var bgltStop:Number = -1500;
var fgltStop:Number = -900;
var bgSpeed:Number = 1;
var fgSpeed:Number = 2;
scrollButton_mc.onRollOver = function() {
bg_mc.onEnterFrame = function() {
this._x -= this._parent.scrollButton_mc._xmouse * bgSpeed;
if (this._x <= bgltStop) {
this._x = 0;
} else if (this._x > 0) {
this._x = bgltStop;
}
};
fg_mc.onEnterFrame = function() {
this._x -= this._parent.scrollButton_mc._xmouse * fgSpeed;
if (this._x <= fgltStop) {
this._x = 0;
} else if (this._x > 0) {
this._x = fgltStop;
}
};
};
scrollButton_mc.onRollOut = scrollButton_mc.onDragOut = scrollButton_mc.onRollOut = scrollButton_mc.onDragOut = function () {
delete bg_mc.onEnterFrame;
delete fg_mc.onEnterFrame;
};

Hope that helps out..
