I would like to know if anyone is up for the challenge of providing an example (or hints) of how to make a trail follow the projectile from the sling shot?
I've looked at a great example called 'Angry Click' yet I would like to know how to create a trail effect that that show the last path the Projectile took.
or (even better)
Does anyone have any ideas of how to show the path the projectile will take? As in the style of Angry Birds.
