Global Variables

[poncianux]

Hey there, this is my first post.

I want to know if LUA can globalize variables through resources.

Example:

**You have one variable on a clientside/serverside resource called R1

wich contains his own meta.xml and one LUA file script.lua

In script.lua you have the next variable:

local XL3 = "Content" 
local LX10 = 0 

**You have other resource with the same description but name: R2

His LUA file named file.lua

In file.lua you want to use the variable "XL3" and "LX10" from R1 on R2

if (XL3 == "Content") then 
LX10 = 1 

++My point is simple, not so complicated like this, but want to know if in this script language is possible

On VB.net to use global variables you can declare them on a Module

On C# to use global variables you must call the variable from file and specify their use (rw)

Hope you can help me! Thanks

i did a fast try, inserted lol = "testing then did a cmd in another resource and returns "nil"

That is pretty obvious if you dont specify where does the variable comes from! I need to know that! Thanks for reply

A friend tells me that is not possible to call them from other resources.

You can pass values with exported functions.

What exactly I want is to retreive money, wins, age, etc of a player from a resource that have those values to put them on scoreboard, but I dont want that the addScoreboardColumn function had to be on the same resource!

you can use setElementData, getElementData.

Each resource runs in own Lua VM (AFAIK), so global variables is available only inside the resource.

Better than element data: exports

You can use an exported function to return a variable.

local somevar = 1000000 
function getSomeVariable() 
     return somevar 
end 

And in the meta.xml just add:

Then call it like:

exports.resourceNameHere:getSomeVariable()

[Castillo]

yeah, i know that exported functions can be used too for this, but i was trying tell easiest way

[poncianux]

If both ways has same result I think I will use the export method, thank you all for your help!
