This student is trying to create a pong type game with their circuit board. They just need to get the ball moving. Is there a way to add velocity to an object and to bounce off an object in App Lab? they created something similar in Game Lab and wanted to try it in app lab.
Motion is tricky in App Lab since App lab is event driven and doesn’t use the “draw” block like in Game Lab. There are ways to do it, but it is a bit involved. Here’s a link to a previous post and a video created by a teacher who has created a Pong Game in App lab.
Hope this helps!
