Time for action – resetting and changing levels

We'll need to create functions that set up the first and second levels in the game. If a level needs to be replayed, only the current level the user lost in can be accessed. Follow these steps to transition between the levels:

1. Create a new function called changeLevel1(). This will be placed below the updateBall() function:

   function changeLevel1()

2. Clear the bricks group when the player loses the round, and then reset them:

     bricks:removeSelf()
   
     bricks.numChildren = 0
     bricks = display.newGroup()

3. Remove alertDisplayGroup:

     alertBox:removeEventListener("tap", restart)
     alertDisplayGroup:removeSelf()
     alertDisplayGroup = nil

4. Reset the ball and paddle positions:

     ball.x = (display.contentWidth * 0.5) - (ball.width * 0.5)
     ball.y = (paddle.y - paddle.height) - (ball.height * 0.5) -2
   
     paddle.x = display.contentWidth * 0.5

5. Redraw the bricks for the current level:

   gameLevel1()

6. Add an event listener to the background object for startGame(). Close the...
