STEP 18: Final step! Let's link the move_right() function to the right arrow key.

  • Go to and drag Sprite Key Event Handler into the bottom of the main function.
  • At the start of the line, change sprite to player.
  • The second parameter is the function called when the key is pressed. Replace right_key with move_right.
