Hi,

I need to animate lines across a map to show changing troop positions, and I was having real trouble geting nice smooth lines and movements until I found this excellent tutorial by Angie Taylor:

http://www.angietaylor.co.uk/animating-a-line-drawn-on-a-map-indiana-jones-...

But on my map I need multiple lines and held positions, and I can't seem to work out how to adapt this method to allow that, if anyone has any ideas that would be great, thanks!

Okay, sort of worked this out, by sacrificing the auto following camera trick in the tutorial I can just draw on the lines, that should have been obvious, sorry! Just need to figure out a way of adding a decay to the lines now...

Sorry, I'm being stupid today, done. Spend ages being confused and then suddenly it all clicks...

Sometimes just writing out the question helps trigger a solution.
Funny how the brain works.

I didn't see your post when I put that last comment up, but yeah, just 'talking' about it can really help sometimes!

In case some one reads this thread where I've asked a question and then answered it myself (replying to yourself on an internet thread is the first sign of madness these days, yeah?), I have another related question...

I have little arrows that auto orientate to the path of the line - nice little built in feature that, had images of keyframing the turns in running through my mind - but the point where the path starts moving and finishes causes the arrow to point 90 away from itself (into the third dimension), and rotate slightly across the flat (second dimension).

I've tried keying out the 90 twist into the third dimension, but I get a flicker when it's rendered.

I've uploaded it to demonstrate what I mean, the problem is most clearly seen at the beginning of the video. The map is rough, don't judge its looks to harshly, please! Although any constructive criticism is always appreciated!

Many thanks,

i'm assuming you are beginning your arrow animation at a zero % keyframe? so why not start with a 1% keyframe and use opacity to bring the arrow into vision? That way your arrow should already be aligned.
