local pf = Instance.new("Folder");
pf.Name = "PlayerFolder";
pf.Parent = workspace;
local parentorso = script.Parent.Torso;
local h = script.Parent.Humanoid;
local dist = 20
local function sortplayers(player)
    player.CharacterAdded:Connect(function(character)
        character.Parent = pf;
    end)
end

local follow

local function GetNearestPlayer(WorldPos)
    for _,player in pairs(pf:GetChildren()) do
        if player.HumanoidRootPart then
            if player.Humanoid.Health > 0 then
                local distance = (player.HumanoidRootPart.Position - WorldPos).Magnitude
                if distance >= 20 then
                    dist = distance
                    follow = workspace[player].Torso
                    print(player.Name)
                    return player;
                end
            end
        end
    end
end

while true do
    wait(1)
    GetNearestPlayer()
    print(follow.Parent.Name)
end

game.Players.PlayerAdded:Connect(sortplayers)


local pfs = game:GetService("PathfindingService");
local path = pfs:FindPathAsync(parentorso,follow);
local points = path:GetWaypoints();
if path.Status == Enum.PathStatus.Success then
    for i,v in pairs(points) do
        h:MoveTo(v.Position)
        h.MoveToFinished:Wait()
        if v.Action == Enum.PathWaypointAction.Jump then
            h.Jump = true
        end
    end
end

I am trying to make a script that makes a NPC walk towards the nearest player. Unfortunately, the player keeps returning as nil?

What line is the error showing at? Dovydas1118 1495 — 4y

line 34, when i try to print the value of the player AcrylixDev 119 — 4y

Instead of putting player's character into a folder, you could use the game.Players:GetPlayers() function in here. I'm not sure if it will fix, you might need to edit my script here a bit, but at least that's how I would do it.

local function GetNearestPlayer(WorldPos)
    for _,player in pairs(game.Players:GetPlayers()) do
        local char = player.Character
        if char.Humanoid.Health > 0 then
            local distance = (char.HumanoidRootPart.Position - WorldPos).Magnitude
            if distance >= 20 then
                dist = distance
                follow = workspace[player].Torso
                print(player.Name)
                return player;
             end
        end
    end
end

Thanks, it worked! AcrylixDev 119 — 4y

Actually uh, character has turned into nil... It worked when i first tested it AcrylixDev 119 — 4y

Sometimes it works, sometimes it doesnt, ill add a waitforchild AcrylixDev 119 — 4y

If so, then you might want to try adding player.CharacterAdded:Wait() in front of the char variable. d4rkn_ess 50 — 4y

Or just change the variable to local char = player.Character or player.CharacterAdded:Wait(), that should work too. d4rkn_ess 50 — 4y
