Hey, I want make a module script for finding the nearest player and use it everytime when I need it.
This is what I have seen so far but how can I import that in a module script?

I want also let it work with a if statement

and also how could I make this script work? While you helping me I am trying to do this myself

local npc_directory = game.Workspace['npc_folder'] --put the name of the folder here

local function ClosestHumanoid(player)
  local players = game.Players:GetPlayers();
  local npcs = npc_directory:GetChildren();
 
  local closest = { humanoid = false, distance = math.huge } --where we will store the closest humanoid found so far, along with how far away it is
  local character = player.Character or player.CharacterAdded:wait();
  local root = character:WaitForChild('HumanoidRootPart', 1);

  local to_check = npcs;
  for _,PLAYER in pairs(players) do
    if PLAYER.Character and PLAYER ~= player then
      table.insert(to_check, PLAYER.Character)
    end
  end

  for _,humanoid_model in pairs(to_check) do
    local displacement = (humanoid_model .HumanoidRootPart.Position - root.Position).magnitude;
    if displacement < closest.distance then
      closest.distance = displacement;
      closest.humanoid = humanoid_model:FindFirstChild('Humanoid');
    end
  end

  return closest.humanoid
end

Also if you can please let me know. can I can use a if statement with a modul?

I made a Humanoid npc_directory in game.Workspace but how can I put all my Players in it when they join in the game?

and also how can I let all player be in there?

game.Players.PlayerAdded:Connect(function(player)
—?
end)

game.Players.PlayerAdded:Connect(function(player)
player.CharacterAdded:connect(function(char)
char.Parent = game.Workspace.npc_directory
end)

this is to parent the player in the folder

To put this function in a modulescript, you have to make a modulescript and put it somewhere (I recommend ServerStorage if multiple scripts are going to use it). If you open it it looks like this:

local module = {}

return module

you can rename ‘module’ to whatever you want. then you have to make a function in that moduleScript. There are multiple ways to do this. you can do this:

local module = {}

module.ClosestHumanoid = function()
    -- the function here
end

return module

or you can do this

local module = {}

function module.ClosestHumanoid()
    -- the function here
end

return module

if you want to use this function in another script, you first have to require it. That looks like this

local ModuleScript = require(path_to_module)

then you just have to call that function in that script

local ModuleScript = require(path_to_module)

local closestHumanoid = ModuleScript.ClosestHumanoid(player)

I don’t really know what you mean, but you can use if statements in moduleScripts and you can check the returned value of the function in the modulescript by doing this

local ModuleScript = require(path_to_module)

local closestHumanoid = ModuleScript.ClosestHumanoid(player)

if closestHumanoid then
    -- do something
end

if you put a little wait in @MrchipsMa code then it works. There is probably a better solution, but this is the one I can think of now.

game.Players.PlayerAdded:Connect(function(player)
    player.CharacterAdded:connect(function(char)
        wait()
        char.Parent = workspace.npc_directory
    end)
end)
