Hi.
Basic thing, I know, but I've been searching for a while cant find what I need.
We are used to using scrollers that control a Netstream object, but now we
have a project where the same scoller needs to control the playback of the main
timeline. So have the scruber move automatically when as the movie plays, but
also be dragable to advance or rewind the SWF.
Anyone got code or tutorial we could use?
thanks |

create a scrollbar and determine the slider's two extreme positions. use the
following function to find the parameters needed for a linear equation to have
the sliders extreme positions associate with frame 1 and _totalframes of your
timeline of interest and the linear equation parameters that will associate
frame 1 and _totalframes with the slider's extreme positions.
you can then define drag and drop methods for the slider and start a loop when
the slider is being dragged so you can update the timeline's _currentframe and
use a loop to update the slider's position when your movieclip is playing.
function solveF(x1,x2,y1,y2):Array{
m=(y1-y2)/(x1-x2);
b=y1 - m*x1;
return [m,b]
