How can I make a global function,variable etc.

What do you mean? Do you mean one that can be used across multiple scripts, or one that can be accessed anywhere from one script?

You want a module for multiple scripts, and just don’t put local for normal scripts.

If your taking about global things then you would use _G but I advise against that

You can just use a module script and store the hello function inside of it

local module = {}


function module.Hello()
   
end

return module

You need a module, then. Insert a ModuleScript. _G and module are the only two ways really.

In the module:

local module = {}

function module.hello()
    print("hello")
end

return module

then, require it:

local mod = require(path_here)

mod.hello()

@astraIboy beat me to it :confused:

Why dont you want to use module scripts though, they are exactly for this purpose

But the best practice is to use module to store functions you’ll be using in various scripts

#11

I know how to use modulescript i just need to use functions globally

#12

Okay well the only other way you can do that is through _G

Also keep in mind _G only works on the same context level so that means if you have a global function on the client you can’t use it on the server and vice versa

but what is the reason behind not using module scripts to achieve something a module script does?

It is hard to tell but I want to rename _G globally

#17 
local GlobalFunction = _G

GlobalFunction.Hello = function()

end

That probably won’t work and also why are you trying to rename _G, I dont even think you can rename globals you can only assign them to variables

sript1

Hello = _G
Hello.MyNum = 10

script2

print(Hello.MyNum)
#20

And I know it is possible because a youtuber did it
