--Initial Settings
display.setStatusBar( display.HiddenStatusBar ) --Hide status bar from the beginning


-- Import sqlite and storyboard
local sqlite3 = require("sqlite3")
local storyboard = require "storyboard"
storyboard.purgeOnSceneChange = true --So it automatically purges for us.



--Create a constantly looping background sound...
local bgSound = audio.loadStream("sounds/bgSound.mp3")
audio.reserveChannels(1)   --Reserve its channel
--audio.play(bgSound, {channel=1, loops=-1}) --Start looping the sound.


--Activate multi-touch so we can press multiple buttons at once.
system.activate("multitouch")


--Create some level globals used in the game itself/gameWon/gameOver scenes.
_G.amountofLevels = 3
_G.currentLevel = 1
_G.levelScore = 0  


--Create a database table for holding the high scores per level in.
--We only need a small database as we dont need to save much information.
local dbPath = system.pathForFile("levelScores.db3", system.DocumentsDirectory)
local db = sqlite3.open( dbPath )	

--Current 2 levels. Add more rows to make more levels available. Also remember if
--you add an extra row into this database you need to add an exta level to
--"amountofLevels" above.
local tablesetup = [[ 
		CREATE TABLE scores (id INTEGER PRIMARY KEY, highscore); 
		INSERT INTO scores VALUES (NULL, '0'); 
		INSERT INTO scores VALUES (NULL, '0'); 
		INSERT INTO scores VALUES (NULL, '0');
	]]
db:exec( tablesetup ) --Create it now.
db:close() --Then close the database
