Animate a line along a path

[Wind-2013]

Hello!
How can I animate a line moving along the path?
Something like this

Or it is not possible in Moho 12?

Thanks =)

2 ways:

- Stroke exposure.
- Masks.

or bones - use a bone to stretch the line.

But that only works with straight lines ...

For something like that, I`d also go for stroke exposure.
I`ve used the same approach since the existing path can be used for circles to follow and the timing is easy to sync.

Another vote for Stroke Exposure.

But careful, the tool is a little broken: Motion graphs do not work.

Also, Follow Path and Stroke Exposure work differently around vertices/bends: Follow Path keeps the velocity constant while Stroke Exposure slows down and speeds up around bends. At least in some instances.

But that only works with straight lines ...

the quick and dirty example I tried used one bone per (straight) segment... the OP example is, essentially, just straight lines that are joined together at an angle...
the "head" vectors are bound to a control bone that extends the bone chain one bone at a time until the bone hits it length limit, then the control re-parents to the next one... and so on...

but yeah - many ways to handle this... the compelling idea for me was to have the head control the movement rather than trying to sync line exposure and head motion
