Trace of light around a shape

Well I see it all the time but now I cant find an example…

Ever see how people will make a trace of light go around the outline of a shape?

I know how to do the motion etc… but I can seem to make the little trace of light look correct…

Anyone know how everyone does this?

thanks

I think this is the sort of thing you mean; Its an extremely simple example but maybe will help you understand

THANKS MAN!

I get it… I was making it to hard!

You just draw a line in whatever pattern you want…

Then mask the line… and tween a basic gradient across it…

Thanks again

Your welcome, there are tutorials dotted about on this but they tend to make it look harder than it actually is.

You still around?

Can you look at with with me…
It seems easy enough… but nothing shows when I test the movie…

thanks

oops, forgot to tell you, you have to convert the lines to fills.

ahhh… will try… thanks…

also, I see you used shape tweening… any reason you did not just use motion tween to send the graient across the screen?

thanks so much for your time.

no, it was just quickly made as an example for someone else

cool… yeah I got mine going now… rock & roll.

well i will leave you alone now… thanks again… you are a credit the net community.
