to control speed adjust scrollTSpeed. to make it infinite, add enough to contentMC so the left side of contentMC is also on the right side of contentMC. you need maskMC._width's worth of duplicates. when contentMC's left edge is aligned with maskMC's left edge reposition contentMC so the left-edge of the duplicates on the right side are at the maskMC's left edge. likewise, for when the right edge of the right side of contentMC is at the right-edge of maskMC.
I'm sorry to say I'm a little confused?!
Am I to do this on the stage or within the AS panel?
I am very new to all this, would you be able to show me in code?
for your help
