Tracking by an increment of 3

Uncategorized

Hi all,

Hopefully there will be a simple solution to my problem.

I have an onEnterFrame event that happens when I am dragging a wheel. At a certain point during dragging, a boolean statement is set to true, and a mc with 120 (120*3=360) frames is targeted, so that when the user drags a wheel, if rotation is incremented +/-3, the mc._currentframe is +/- one frame.

the mc is 120 slices serving as a mask of a circular bar, which is hidden or exposed depending on the rotation of the wheel by the user.

[COLOR=Red]The problem I have is tracking when the rotation has incremented by +/- 3[/COLOR], since Im using onEnterFrame I cant find out how to store the rotation variable somewhere when it hits the +/-3 mark, and then continuly check for the next increment.

Here is the code :
