No it doesnt keep counting them hahah.
Its a method to generally detect the second or third touch, like the double tap.
Generally youd be aiming for 0.
Just imagine if you use two fingers to swipe two different slab,one of the swipes would have 1 :)That would make a lot more sense.
Anyway, I get all these concepts, but am still not sure exactly how to go about this. How do I create just one projectile per swipe?
