More Efficient Value Checking?

[Th1rust (Ozzy)]

I want to check if a bunch of global variables ~= nil, but its very ineffecient and repetitive to write out

if _G.a ~= nil and _G.b ~= nil and --[[repeat until your fingers hurt]]--

Could you instead do something like this?

if (_G.a and _G.b and _G.c) ~= nil then

Just iterate through the variables?

local isAllNil = true
for _, value in table_of_variables do
    if value ~= nil then
        isAllNil = false
        break
    end
end
if isAllNil then blah blah blah

P.S. Global state is evil.

Neither:

if _G.a and _G.b and _G.c then

end

Also what @Pokemoncraft5290 said at the bottom

I’ll have to test this. I use global variables to avoid value instances, this script acts as a sort of value manager for the other’s. Thank you.

So, when you use an if statement like that it doesn’t check for true and instead checks if it has a value or exists?

Yep
