How to know if a specific thing is in a table

[MrUserNumber (User)]

1. I want to know how to detect if something is in a table.

For example:

local table = {"1", "2"}

I want to know if it has a specific thing inside like if I wanted to find 1. Or If I wanted to find a player or something like that.

if table.find(table, "1") then

[Mortai_Yt (xM_MORT)]

use table.find. example:

local YourTable = {"1", "2"}

if table.find(YourTable, "1") then
    print("Found!")
else
    print("Not Found!")
end

Also keep in mind you shouldn’t define a variable with the name “table” because that would override the table library.

How would I find something inside of a table inside of another table for example?

local Table = {
	["anotherTable"] = {
		"1", "2"
	}
}

[Mortai_Yt (xM_MORT)]

Try this:

local Table = {
	["anotherTable"] = {
		"1", "2"
	}
}

if table.find(Table["anotherTable"], "1") then
    print("Found!")
end

and if you dont know which table its in, you could do something like

for _, v in pairs(Table) do
 if table.find(v, "1") then
  print("Found!")
  break
end

(untested so it might have some stupid mistakes)

It’s just a good idea to check if the value is a table using typeof(v) == "table":

-- Whole Code
for _, v in pairs(Table) do
 if typeof(v) == "table" and table.find(v, "1") then
  print("Found!")
  break
end

What if your trying to find something specific and this is your table

local Table = {
	["1"] = {
		"1", "2"
	},
	["2"] = {
		"1", "2"
	}
}

We can see this is a dictionary and not an array, hence using table.find() wouldnd work.

Lets say you want to get the “2” from the first key-value:

print(Table["1"](2))-- should print 2 since each key in the dictionary has a table value, we can get the value from that table by using its index

You would have to use recursion and check the value type of the current level being iterated. And you would need a concrete method to identify the required table/value to return successfully from a possibly multi nested function.

[GuySalami (Choco1atte)]

It should still work, does it not?

Never mind, it is a dictionary, we would do recursion

function loop(t : {}, val : any, depth : number)
	if depth == 0 then
		return nil
	end
	
	for k, v in pairs(t) do
		if v == val then
			return true
		end
		
		if typeof(v) == "table" then
			local res = loop(v, val, depth - 1)
			
			if res then
				return true
			end
		end
	end
end

loop(Table, val, -1) -- -1 goes forever

(not tested, but should work.)
