Mac下cocos2dx3.1用Cocos IDE写的Lua binding篇01

本人Lua新手，写着玩玩。

新建一个模版project。

一、改动main.lua

require "Cocos2d"

require "Cocos2dConstants"

-- cclog

cclog = function(...)

print(string.format(...))

end

-- for CCLuaEngine traceback

function __G__TRACKBACK__(msg)

cclog("----------------------------------------")

cclog("LUA ERROR: " .. tostring(msg) ..
"\n")

cclog(debug.traceback())

cclog("----------------------------------------")

return
msg

end

local function
main()

collectgarbage("collect")

-- avoid memory leak

collectgarbage()

collectgarbage()

cc.Director:getInstance():getOpenGLView():setDesignResolutionSize(,
, )

cc.FileUtils:getInstance():addSearchPath("src");

cc.FileUtils:getInstance():addSearchPath("res");

--support debug

local targetPlatform = cc.Application:getInstance():getTargetPlatform()

if (cc.PLATFORM_OS_IPHONE ==
targetPlatform) or (cc.PLATFORM_OS_IPAD ==
targetPlatform) or

(cc.PLATFORM_OS_ANDROID == targetPlatform)
or (cc.PLATFORM_OS_WINDOWS ==
targetPlatform) or

(cc.PLATFORM_OS_MAC == targetPlatform)
then

cclog("result is ")

--require('debugger')()

end

-- run

local sceneGame = cc.Scene:create()

sceneGame:addChild(require("scripts.StartScene"))

if cc.Director:getInstance():getRunningScene()
then

cc.Director:getInstance():replaceScene(sceneGame)

else

cc.Director:getInstance():runWithScene(sceneGame)

end

end

local status,
msg = xpcall(main, __G__TRACKBACK__)

if not status
then

error(msg)

end

二、新建一个目录scripts,当中新建一个StartScene.lua文件

local sceneStart =
nil

visibleSize = cc.Director:getInstance():getVisibleSize()

-- create text

local function
createText()

local alert = ccui.Text:create()

alert:setString("Hello World")

alert:setFontName("Marker Felt")

)

,
, ))

alert:setPosition(cc.p(visibleSize.width /
2.0, visibleSize.height /
2.0 ))

return
alert

end

-- create farm

local function
createLayerFarm()

local layerFarm = cc.Layer:create()

-- add text

local
spriteText = createText()

layerFarm:addChild(spriteText)

return
layerFarm

end

if sceneStart ==
nil
then

sceneStart = cc.Scene:create()

sceneStart:addChild(createLayerFarm())

end

return sceneStart
