Hi guys,

Newbie here. (sorry in advance if this has been asked already)

I’ve seen a lot of mouse trailer effects with action script but I’m trying to find a way to make a similar ‘trailer’ or ‘tail’ effect to follow an object that is tweened on the stage.

Anyone know how to do this?

Example: sphere symbol is tweened and follows a guide in a arch. I’d like to apply an action so there is a tail to it that nicely trails the sphere to make a realistic looking comet shooting across the sky. (with bunch of dust or small stars sparkling behind)

Your help is much appreciated!!!

Cheers
