Re: FLASH: animate line on a curve

[Byron Canfield]

There are basically two ways to do this. Neither of them, however, involves

shape-tweening a line, which works predictably only with straight lines.


One way involves creating essentially single frame animation by starting

with a keyframe containing the whole finished line, adding keyframes,

erasing a bit of the line, and adding more keyframes and erasing. Then

reverse the order of the frames.


Another involves using a mask layer to reveal only portions of the line at

a time.


You can see a simple demo of these two methods at:
