How do I use "_G" in ROBLOX scripting?

_G is and how it works in ROBLOX Lua. It is a predefined global table that contains all the global variables, functions, and other values that are accessible throughout the game. You can use _G to access and manipulate these global values, as well as to define new global values.

Using _G can be useful in certain situations, such as when you need to access a global value from multiple different scripts, or when you want to override or redefine an existing global value. However, it is generally a good idea to use global values sparingly and with caution, as modifying global values can have unintended consequences.

lmao your response made me laugh, good job. :smiley:
but is it a replacement of variables and is there any other use case and was I right?

#27

It’s not really a replacement, just another way to reference and define them.
No, there aren’t any other use cases to my knowledge.
right in what?

yeah you can do it with functions / arrays / tables as well (i forgor :skull:)
anything that you put after local, you can use _G for, basically.

Can someone get a moderator to close this post? We don’t need these kinds of arguments in the forums.

_G is a global array in Lua that can be used to share information across multiple scripts that are running at the same context level. For example, it might be useful to store a string for multiple scripts to use:

-- Script 1
_G.MyInfo = "Hello, world!"

-- Script 2
print(_G.MyInfo) -- output: Hello, world!

shared is the Luau version of _G, hence they have the same behavior.
