Help. Scroll movieclip doesn't work inside movieclip

**daynie** · 05-15-2011, 02:39 AM

Dear All,
Need Help. I create movieclip called 'pinguin1' and attached with code. Inside 'pinguin1' mc contain scrollable movieclip called 'main_mc' with code too.
Problem is when 'pinguin1' start 'main_mc' won't work, text won't getting scrolled up and down. If I build only 'main_mc' (outside 'pinguin1') it work well.
Is there any wrong code?

Appreciate all. Ty

pinguin1 code :

Code:

on (release) {
_root.x +=2;
_root.pinguin1.swapDepths(_root.x);
play();
}

main_mc code :

Code:

//editable variables
var scPadding:Number = 5;
var scrollbarOffset:Number = 10; //distance from scPadding
var scrollbarWidth:Number = 2;
var scrollHandleRadius:Number = 5;
var scrollExpand:Number = 6; //scroll face hit area expand
var scrollHandleColor:Number = 0x000000;
var scrollHandleAlpha:Number = 100;
var scrollFaceColor:Number = 0x000000;
var scrollFaceAlpha:Number = 100;
var friction:Number = 1.3;
var projectSpeed:Number = 3.5;
var wheelMultiplier:Number = 15;
