I need a blink effect (or called flash?) like the one used here: http://www.youtube.com/watch?v=go7rlvyI7Ys
I tried it using Texplay, but it's kinda limited. I coulnd't find a way to turn my image all white and slowly change it back.
My approach then was to copy my image, draw it over my original image and make it from white to 100% opacity. But
I noticed that's not the best performant way and I wasn't even able to turn my image white or change it's opacity... instead I drew a reddish rectangle on top
of my CLONED image. Then I switch between those two images every x frames to simulate a blink effect. Well, ...
can anyone suggest a better way to implement a blink using Texplay?
