How to telephone call functions in other script files in Roblox

Solution 1

An alternative to _G is to use the too globally avaliable table, shared. Shared is used the same style _G is, but you lot must specify "shared" earlier the variable identifier, unlike _G, where you can merely write the proper name of the variable without the _G (non anymore in ROBLOX). Shared is used in the following context:

          shared["variablename"] = value                  

Just like in the global stack, _G. Instance usage of shared:

Script one

          shared["rprint"] = function(array) for i,v in pairs(array) practice print(i, five) end finish                  

Script ii

          repeat wait() until shared["rprint"] shared.rprint({"Hello, ", "How", " are", " you lot?"})                  

The output of this script would be "Hullo, How are y'all?"

Solution two

The simplest way would be to use _G or shared.

In one script,

_G.myFunction = part(Arguments)

-- blah

cease

In some other script, yous would employ this code.

repeat expect() until _G.myFunction ~= nil

_G.myFunction()

This would also piece of work with the global table shared, instead of _G.

Solution 3

I know information technology has been said before, but just use the normal _G or shared to admission it.

Script one

          _G.myFunction = office()      print("Hello, myFunction!") stop                  

Script ii

          repeat wait() until _G.myFunction() _G.myFunction()                  

Output

Hello, myFunction!

Solution four

You can make the function global. In one script practice this:

              _G.myFunction = function() impress("How-do-you-do World") end                          

In another script practice this:

              repeat look() until myFunction myFunction()                          

By defining a function is _G you must await for the script to execute assigning the part, and so you can call the part fifty-fifty without specifying _G.

This won't piece of work because, due to ROBLOX updates, you at present have to alphabetize _G whenever you access items inside it.

You cannot use dofile() in ROBLOX, either, every bit I saw mentioned above.

In answer to the question: you need to create a function in one script into the global table - _G, by adding _G.MyFunction = function(parameters) finish. In another script, you demand to access information technology inside the _G tabular array - _G.MyFunction().

A mutual problem that appears for ROBLOX scripters is that y'all try to access your role inside _G before it is created. A elementary way to solve this is to add a wait until information technology is created, as suggested from Camoy'southward mail service:

            repeat wait() until _G.MyFunction()                      

Solution five

Yous could use Module Scripts which were thankfully added. You could put the functions in there, and so call and use them anywhere else!

How to share variables through different scripts Roblox Studio

Comments

• I have a script file embedded in the Workspace that contains functions. I would like phone call these functions from script files embedded in child objects of the Workspace. I don't want to have to re-create and paste these functions into multiple script files. I figured the object oriented approach would exist best if its possible.

• Voted upward as the _G variable has been removed from the Roblox Scripting API. This respond shows the table that is now used to 'share' values between scripts.

• Good. People should know about shared, as it'due south pretty important when you have no other alternative.

• @JonLyles "it was possible to read values from it without writing _G in front end. This is no longer the case." (from the wiki)

• then yous can telephone call the function even without specifying _G non anymore
