Time for action – tracking the score

The score updates through a parameter called scoreNum and displays it during the game play. The score number is received through gameScore.

1. The next function that will be created is called setScore with a parameter called scoreNum:

   local setScore = function( scoreNum )

2. Use a local variable called newScore and set it as scoreNum. Set the gameScore = newScore. Provide an if statement for gameScore, so that the score during game play is set to 0:

     local newScore = scoreNum
     gameScore = newScore
   
     if gameScore < 0 then gameScore = 0; end

3. Add the scoreText display object and make it equal to gameScore. Close the function:

     scoreText.text = gameScore
     scoreText.xScale = 0.5; scoreText.yScale = 0.5
     scoreText.x = (480 - (scoreText.contentWidth * 0.5)) - 15
     scoreText.y = 20
   end

What just happened?

For setScore = function(scoreNum), we set a parameter called scoreNum. The scoreNum parameter will update the game score continuously through local newScore. newScore...
