        local inGameLayer = cc.Layer:create()
        return inGameLayer
    end

最基本的场景

 local sceneGame = cc.Scene:create()
    sceneGame:addChild(createInGameLayer())

cc.Director:getInstance():runWithScene(sceneGame)
cc.Director:getInstance():replaceScene(cc.TransitionFade:create(1,WelcomeScene.createScene()))

最基本的精灵

        inGameLayer:addChild(bg)
        return inGameLayer
end

local function tick()

       end

       cc.Director:getInstance():getScheduler():scheduleScriptFunc(tick, 0, false)

最基本的触摸事件

local touchBeginPoint = nil
        local function onTouchBegan(touch, event)
            local location = touch:getLocation()
            cclog("onTouchBegan: %0.2f, %0.2f", location.x, location.y)
            touchBeginPoint = {x = location.x, y = location.y}
            -- CCTOUCHBEGAN event must return true
            --[[多点
             for i = 1,table.getn(touches) do
             local location = touches[i]:getLocation()
             Sprite1.addNewSpriteWithCoords(Helper.currentLayer, location)
             end
            ]]--
            return true
        end

        local function onTouchMoved(touch, event)
            local location = touch:getLocation()
            cclog("onTouchMoved: %0.2f, %0.2f", location.x, location.y)
            if touchBeginPoint then
                local cx, cy = layerFarm:getPosition()
                layerFarm:setPosition(cx + location.x - touchBeginPoint.x,
                                      cy + location.y - touchBeginPoint.y)
                touchBeginPoint = {x = location.x, y = location.y}
            end
        end

        local function onTouchEnded(touch, event)
            local location = touch:getLocation()
            cclog("onTouchEnded: %0.2f, %0.2f", location.x, location.y)
            touchBeginPoint = nil
            spriteDog.isPaused = false
        end

        local listener = cc.EventListenerTouchOneByOne:create()
        --local listener = cc.EventListenerTouchAllAtOnce:create() 多点
        listener:registerScriptHandler(onTouchBegan,cc.Handler.EVENT_TOUCH_BEGAN )
        listener:registerScriptHandler(onTouchMoved,cc.Handler.EVENT_TOUCH_MOVED )
        listener:registerScriptHandler(onTouchEnded,cc.Handler.EVENT_TOUCH_ENDED )
        local eventDispatcher = layerFarm:getEventDispatcher()
        eventDispatcher:addEventListenerWithSceneGraphPriority(listener, layerFarm)

最基本的音乐

--local bgMusicPath = CCFileUtils:getInstance():fullPathForFilename("background.ogg")

   local bgMusicPath = cc.FileUtils:getInstance():fullPathForFilename("background.mp3")

   cc.SimpleAudioEngine:getInstance():playMusic(bgMusicPath, true)
   local effectPath = cc.FileUtils:getInstance():fullPathForFilename("effect1.wav")

   cc.SimpleAudioEngine:getInstance():preloadEffect(effectPath)

   local function menuCallbackOpenPopup()
           -- loop test sound effect
           local effectPath = cc.FileUtils:getInstance():fullPathForFilename("effect1.wav")
           effectID = cc.SimpleAudioEngine:getInstance():playEffect(effectPath)
           menuPopup:setVisible(true)
       end

最基本的加载图片

cc.Director:getInstance():getTextureCache():addImageAsync("DartBlood.png",imageLoaded)
local texture0 = cc.Director:getInstance():getTextureCache():addImage( "Images/grossini_dance_atlas.png")

function LoadingScene.imageLoaded( pObj)
    -- body
end

cc.Director:getInstance():getTextureCache():removeTextureForKey("Images/grossinis_sister1-testalpha.png")
cc.Director:getInstance():getTextureCache():removeAllTextures()
cc.Director:getInstance():getTextureCache():removeUnusedTextures()

local cache = cc.SpriteFrameCache:getInstance()
cache:addSpriteFrames("animations/grossini_gray.plist", "animations/grossini_gray.png")
SpriteFrameTest.m_pSprite1 = cc.Sprite:createWithSpriteFrameName("grossini_dance_01.png")

最基础的动作

local function CallFucnCallback1()

end

local action = cc.Sequence:create(
        cc.MoveBy:create(2, cc.p(200,0)),
        cc.CallFunc:create(CallFucnCallback1) )
 grossini:runAction(action)

最基础的字符格式化

string.format("grossini_dance_%02d.png", j + 1)

最基础的按钮

local start = cc.Sprite:createWithSpriteFrameName("start.png")


local  startItem = cc.MenuItemSprite:create(start, start, start)


local function menuCallback(sender)
    cclog("menuCallback...")
    --tolua.cast(ret:getParent(), "cc.LayerMultiplex"):switchTo(1)
end


startItem:registerScriptTapHandler(menuCallback)
startItem:setPosition(50,50)


local  menu = cc.Menu:create()
menu:addChild(startItem)
menu:setPosition(0,0)
layer:addChild(menu)
