cocos2dx 3.17.2 新项目lua编译错误

Cocos2d-x
#1

最近在学习cocos2dx lua编程，开发环境是cocos2dx 3.17.2+sublime 3，开发环境搭建都没问题，hello world 项目可以正常运行，自己学习新建一个hello world 提示LUA ERROR] load “.\app/views/CLogonLayer.lua”, error: syntax error during pre-compilation.我查了很多遍觉得没有问题，网络搜索了一天没找到解决方案，麻烦大侠帮忙看看。

这提示是CLogonLayer.lua文件里边有语法错误吧

第五行在end附近少了个等号

#7

谢谢了，我重新敲了一遍代码，出现了[LUA-print] USE " cc.exports.createLayer = value " INSTEAD OF SET GLOBAL VARIABLE
要崩溃了，一个hello world 学的太艰难了:sweat:

哪位大哥帮忙看看，编译不过去自己写抄写的hello world，信心严重受损，这个代码我是抄写，意思我感觉理解了，到底哪里出错了:innocent:

#9

Hello Lua和Arial的引号用了中文的引号“”,应该用英文的引号""。以上是我猜的

#10

谢谢回复，我查了一下是英文的引号，没有问题:innocent:hello world.rar (1.1 KB)
local size = cc.Director:getInstance():getVisibleSize()

local gameScene = class(“gameScene”,function()
return cc.Scene.create()

end)

function gameScene:create()

local scene = gameScene.new()
scene.addChild(scene.createLayer())
return scene

end

function createLayer()
local layer = cc.layer:create()
local label = cc.label:createWithSystemFont(“hello world”,“Arial”,32)
label:setPosition(cc.p(size.width/2,size.height/2))
layer:addChild(label)
return layer

end

return gameScene

#11

cc.FileUtils:getInstance():setPopupNotify(false)

require “config”
require “cocos.init”

local function main()
local scene = require(“app.views.gameScene”)
local gameScene = scene.create()
cc.Director:getInstance():runWithScene(gameScene)

end

local status, msg = xpcall(main, G__TRACKBACK)
if not status then
print(msg)
end

两个lua文件，一个简单的创建场景，一个main，hello world这也太…,local status, msg = xpcall(main, G__TRACKBACK)楼上代码复制不知为何缺少了__,原始代码没问题我查过了，哪位高人帮忙看一下什么原因，整了两天了没找出问题

#14

禁用了全局变量吧

#15

谢谢回复，禁用了也没一样:joy:，又弄了大半天，还是没得希望

#16

是禁用了全局变量，而你使用了全局变量。可以用 cc.exports. 声明全局变量 或者config.lua 把全局变量打开

#17

function createLayer() 这个函数名改为function gameScene.createLayer()

#18

config.lua禁用全局变量，CC_DISABLE_GLOBAL = flase，然后提示的更是未知的错误:joy:这个错误我在百度搜索不到:joy:

这个错误

#20

一个hello world 之路也太复杂了，学习曲线也太。。。。。。，我都调试了一周都没解决，大老帮忙看一下:slightly_smiling:

#21

调用方法一般用 ：号 . 和冒号是由区别的，：号默认带 self 的，你试一下
我定义方法一般都是 function className:func() end 然后调用用冒号

#22

lua语法简单，但是cocos要有人带，不然自己摸索 是要花更多时间学习的 加油吧
