unknown global arg when making a function with a variable amount of arguments?
a perfect example
function Foo(...)
for k, v in pairs(arg) do
print(v)
end
end
Foo("Hello", "World!", "", "How", "Are", "You", "Today")
for those who dont know, you can make a function with variable arguments via "...", and you access all the arguments as a table via "arg", but roblox keeps saying "W001: Unknown global "arg"", help?

Interesting. Running it on Lua Interpreter, it works perfectly fine. I guess in Roblox Studio, you would have to declare it as it showed an "Unknown global variable" error. Declare args by doing `local args = {...}` Zafirua 1348 — 5y

Hi fan,
You need to put the infinite arguments inside of a table. So, basically, create a new table and place them in there and then you can loop through them. Because initially, they're just a number of values separated by commas. So, do something like this:
function variadic(...)
local args = {...};
for _, arg in next, args do
-- Blah
end
end
Hope I helped and have a wonderful day/night.
Thanks,
Best regards,

After a little bit of researching, I found out that OP's code *does* work in Lua 5.2, just not in Lua 5.1; Zafirua 1348 — 5y
