I dont know if you have played the mobile-game Flappy Fall. Its a simple game whit "falling"(scrolling) birds in a certain pattern, you have to catch them in a nest before they hit the ground. I am currently trying to learn a thing or two about Sprite-Kit and i am curious what is the best way to achieve different patterns in scrolling sprite-nodes? Lets say they are scrolling down the screen from one side to another and randomly have small waves and big waves. Any tips will be appreciated !
I am not trying to copy the game, just learn technics!
