Hi all,

I have been given the task of adding a scoring system to various flash games. This simply involves taking input, adding functionality such as pausing and replaying and then outputting the score, time left etc. at the end.

I've so far successfully edited two games. Both these games used the "actions" code on frames. The latest game I'm trying to do uses an actionscript class which makes it both easier and harder.

I'm not very adept at flash at all, but I've worked it out so far. I've added various movie clips that are to be used for displaying the pause screen background, buttons for replaying etc.

I've been showing and hiding these using:

back._visible = true;
//movie clip, instance of back (back.png)

I doubt it's best practice, but it's quick and has been working. However, now with the change of coding style to classes, this doesn't seem to work. I kinda understand why, but I'm now unsure how to hide/show these elements.

Any help would be greatly appreciated :) I've attached the modified AS.

class RivalOrbs extends MovieClip
{
    var infinite_levels, orbs_start, orbs_inc, orbs_per_level, show_timer, _parent, one_time_per_level, speed_start, speed_inc_percent, max_speed, percent_starting_on_wrong_side, colorize, colors, secs_per_level;
