Are variables automatically initialized?

[amperbee]

I mean, I can just do this:

internet = 123

Or I have to do this:

if internet == nil then
internet = 123
end

(By the way everytime I do

randomvariablename = 0

Lua halts the entire code because it prevents something about global variables and wants me to use local variables instead, but I need that variable for the entire code, what do I do now? I have the code here just in case)

 

[Zipper]

"local variablename = 0"

there, initialised once, free to be changed everywhere.

(except the variable can only be used within the script it was initialized in, mind)

If I do "local whatever = 0" at the START of the entire lua file, it can be used everywhere in that file, right?

I still don't know, all I want to do is initialize a variable that can be used for the entire file, not just for a block of code, but the entire file.

If you declare a variable outside a function in LUA_XXXX, (in other words, just plaster "local Ilikeplayingpyro = 3" at the top), everything inside LUA_XXXX can read it freely. That's all there is to it.

Thank you Zipper!
