i am implementing a scrolling interface for our online portfolio. Pls see a temp link here: http://www.adventmatrix.com/website/advent.html

In this I am facing a couple of problems:
1. If you go to the extreme sides, the scrolling goes past the "outer" edges of the graphic, and I cant seem to manage this. Is there a better way to implement this?

2. Is there also a way to control the speed of scrolling motion?

Look fwd to your responses.

Thks

As I can see you are scrolling a big MC by reversing the mouse position and multipling for a base value that fits the size of your MC, changing its _x position. All this in a mask.

I might have an idea:

In the place that you added the script, put a conditional situation to this happen like:

Supose that the max left _x you want is -300 (lower then this its going to past the edge)

if (the_result_of_my_var_that_will_set_the_new_x_position > -300)
{
     my_big_mc._x = the_result_of_my_var_that_will_set_the_new_x_position
}
else
{
    my_big_mc._x = -300 // you just don't let it going further
}

now supose that max right _x position is 100. just do the same

if (the_result_of_my_var_that_will_set_the_new_x_position <100)
{
     my_big_mc._x = the_result_of_my_var_that_will_set_the_new_x_position
}
else
{
    my_big_mc._x = 100 // you just don't let it going further
}

This will probably solve your problem.

Thanks fot your comment.

Here is what I am using

onClipEvent (mouseMove) {
_root.menu._x = (165-_xmouse)*0.666666+5;
}

I tried resticting the motion so that it stops scrolling at the 2 exrtreme ends of the graphic. Also i just could not manage the speed with this bit of code.

The scrolling speed of your MC will variate according with its size (width). Larger MC's will scroll faster, after all, you need to cover the hole width by the space of the screen.

Change the name "menu" of your MC to something like "mymc" cuz "menu" is a reserved name.

Now, i can see that when you get close to the edges the movie stays good. the only problem is when the mouse goes off the "show area"

so to solve this try this code:

onClipEvent (mouseMove)
{
      if((_xmouse > -1) and (_xmouse < 1201)) // where 1200 is the width of my MC here. put your MC width here +1
      {
             _root.mymc._x = (143-_xmouse)*0.666666+5; // i used 143 to work here dunno if you have to change to fit yours MC
      }
}
