Essentially the project uses the Collision example project as a basis to do this. (https://spaces.proto.io/project/CCDD39E8-969E-9AFA-C094-3EA4B8A96FD5/Colission/) Checking if the ball is within the bounds of the walls then it would reset the position and increase the score by an increment of 1 respectively to which wall has been 'hit'.
