About LUA module variables

[tipforeveryone]

Here is my custom module:

local module = {}

module.SetValue = function(value)
  module.v = value
end

return module

and this is my code to call above module

local variable1 = require("mymodule")
variable1.SetValue(1)

local variable2 = require("mymodule")
variable2.SetValue(2)

System:Print(variable1.v)
System:Print(variable2.v)

As my expectation, the console should display

1
2

but it displays this instead

2
2

That means the value of variable1.v is overwriten by the value of variable2.v.
I used mymodule for 2 local variables, why dont they hold a independent value of module.v ?

The second time you require('mymodule'), it sees that the variable 'module' already exists and will not create a new object for you. Meaning that variable2 is referencing to the same as variable1.

I think I posted the same answer in discord a while back. 

--my module
mymodule = {}

function mymodule:Create()
	local o = {}
	o.someValue = "1"
					
	function o:SetValue(value)
		o.someValue = value
	end	
	
	return o
end

 

usage:

import "path to mymodule"

local variable1 = mymodule:Create()
variable1.SetValue("test1")

local variable2 = require("mymodule")
variable2.SetValue("test2")

System:Print(variable1.v)
System:Print(variable2.v)

Yes I remember that you explained this to me on discord months ago, I just totally forgot the answers and could not find it again on discord because Josh cancel discord once (I delayed my game development for almost 3 months and returned 1 weeks ago) Thank you again for a clear answer, and now I can bookmark it !
