EXTEND—STEP 2: We've stored the ball's current speed in my_var. Let's increase it!

  • In your toolkit, go to LOGIC, click on and drag in Addition inside your collision event.
  • Click inside the code editor and change what's to the right of the = sign from 2 + 3 to -my_var + 1
  • This reverses the direction of the ball and then increases its speed by 1.
  • Click Run, and then Submit and Next to move on.
