Do the Roll-a-ball tutorial up through step 7 (“Displaying Score and Text”). Switch the colors of the ball and the collectibles; namely, make the ball yellow and the collectibles blue.
Note that the tutorial is using a previous version of Unity. If you could not figure out where things mentioned in the tutorial are in the current version of Unity, please feel free to ask in the forum and TA/Instructor.
Take a screen shot partially through the game, as shown below, and upload it to get credit for this homework.
