How to pass variable from another lua file? Im trying to pass the text variable title to another b.lua as a text.
a.lua
local options = {
title = "Easy - Addition",
backScene = "scenes.operationMenu",
}
b.lua
local score_label_2 = display.newText({parent=uiGroup, text=title, font=native.systemFontBold, fontSize=128, align="center"})
There are a couple ways to do this but the most straightforward is to treat 'a.lua' like a module and import it into 'b.lua' via require
For example in
-- a.lua
local options =
{
title = "Easy - Addition",
backScene = "scenes.operationMenu",
}
return options
and from
-- b.lua
local options = require 'a'
local score_label_2 = display.newText
{
parent = uiGroup,
text = options.title,
font = native.systemFontBold,
fontSize = 128,
align = "center"
}
require 'a' is whatever 'a.lua' is returning -- in this case, your local options in 'a.lua'. Just use a different variable name for each require you do.You can import the file a.lua into a variable, then use it as an ordinary table.
in b.lua
local a = require("a.lua")
print(a.options.title)
require keyword to support any number of arguments, like this: stackoverflow.com/questions/9145432/…, then all you have to do is to merge the tables, like this: stackoverflow.com/questions/1283388/lua-merge-tables.
local a = require("a.lua"), a would be nil
