For the red team you don’t want the bird to hit the red. You want it to hit blue. To block it with the car for red side use w for up and s for down and the arrow keys for blue side. Turn you sound off if the bird noise it too annoying.
I created this in my PLTW class in school. Other people may have created something like that because it is a thing that most do on scratch but this pong game idea was not copied. Have fun!
