Fading out the particles as they reach the deadzone

[sidneydekoning]

Hello,

I have been playing around with the waypoint demo you created, how
ever i want the particles to fade out when they reacht the deadzone.
Is that possible and if so how?

Kind regards,

Sidney

You can extend your own Action2D class.

In this class, define the coordinate of the center of the dead zone. Next, override the update() method; in this method, alter the particle's alpha value according to the dead zone center coordinate.
