Just a simple little setup that lets you interactively activate pinball flippers whenever you hit a button in your user data(or viewport). One thing I forgot to add in the video is that if you want to slow down the flipper you could add a math node right before the trigonometric node and set it to divide, if you do then you will have to extend the count on your compare node(# of frames before it resets) too. I thought it provided some interesting concepts so I hope you enjoy!
