I have a pretty simple task, but there doesn’t seem to be an easier way to do it. Basically, I want to draw an arrow out that follows a non-linear arbitrary path. It’s basically like having a piece of line art that draws itself out. For my purposes, I would need the path that is drawn behind it to be slightly transparent.

Right now, the only thing I can think of is tweening all the straight parts of the arrow and then doing all the bends frame by frame. If tween the bends, I need to do them on separate layers, or else the tweening goes crazy. But then you are able to see all the parts when I turn the opacity down.

Anybody got any suggestions?
