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.
