Time for action – creating our game scene

The GameScene class is already added to the start project and some of the code is already in place. We'll focus first on building the game's interface and listening to touches:

Let's work on the addTouchEvents method:

function GameScene:addTouchEvents()
    local bg = cc.Sprite:create("background.jpg")
    bg:setPosition(self.middle.x, self.middle.y)
    self:addChild(bg)
   
    local function onTouchBegan(touch, event)
        self.gridController:onTouchDown(touch:getLocation())
        return true
    end

    local function onTouchMoved(touch, event)
        self.gridController:onTouchMove(touch:getLocation())
    end

    local function onTouchEnded(touch, event)
        self.gridController:onTouchUp(touch:getLocation())
    end

    local listener = cc.EventListenerTouchOneByOne:create()
       listener:registerScriptHandler (onTouchBegan,cc.Handler.EVENT_TOUCH_BEGAN )
   listener:registerScriptHandler (onTouchMoved,cc.Handler.EVENT_TOUCH_MOVED...
