Get variable from another lua file

[Tomc0]

Hello, if that's going to be a noob question sorry, but I just can't find a great tutorial for my problem.

So, I want to reach a variable from another lua file, like that:

Example1.lua:

function example() 
   string = "Test" 
end 

So, if I'm in another lua file (Example2.lua), and I want to get the "string" variable from the Example1.lua file, what do I need to do?

I heard about "require", but I can't really understand how to use it.

Thanks!

look, if the two files are in the same resource, and same type ( server or client )

You should make the variable global, this happens when you you don't write 'local' before the variable.

example of global variable:

theString = "Hello World!" 

example of local variable:

local theString = "Hello World!" 

If the two files in the same resource, the global variables will be shared in the whole resource, like this

file1.lua

theString = "Hello World!" 

file2.lua

outputChatBox(theString) 

However, if you want to get the value of the variable in another resource, you have to use export functions.

Thanks for the help! And if I want to use a variable from a server side script in a client type script? I can't do it?

Client and server side scripts don't share the variables by default, but you could sync them.

Can you help me with that? Do I need to use the "require" lua statement for that? Thanks!

[Castillo]

"require" on MTA is not used, nor available.

You could send the variable to the client side everytime you update it, or create an element and use element data.

Thanks for the help.

can share variable from server script to another server script?

no, each resource has it's own unique environment.

 

But you can use export functions to retrieve variable values from other resources.

Keep in mind that:

• Tables are deep-copied.
• (loaded) Functions can't be past over.

 

There is also elementdata, that can be act as an in-between storage place, but that has the same restrictions as exports.
