Search for an item in multiple Lua lists

Question

I'm working on a script right now and have encountered a roadblock where I can't quite figure out how to check if a value is in any of the selected tables in Lua.

Example script of the problem below.

players = {213, 644}
helpers = {632, 965}

-- How would I check if a number (for example 632) was in either of these two tables?

Answer 1

Use this simple table find value _v:

local players = {213, 644}
local helpers = {632, 965}

local function find(t, _v)
    for i, v in pairs(t) do
        local type1 = type(v)
        if type1 == 'table' then
            local value = { find(v, _v) }
            if #value ~= 0 then
                table.insert(value, 2, i)
                return unpack(value)
            end
        elseif i == _v or v == _v then
            return i, v
        end
    end
end

-- Example:
print(find(players, 632) and 'Was finded in table: players') -- nil
print(find(helpers, 632) and 'Was finded in table: helpers') -- 'Was finded...'
