Follow Script refuses to work? NPC just stands still.

Hi!

I coincidentally have the same script you do, and for some reason it says "game.Workspace:children()". I don't know why that is, but it should be "game.Workspace:GetChildren()".

This is how the script should be.

function findNearestTorso(pos) --Function that finds the nearest player in range to the zombie
    local list = workspace:GetChildren() --Finds every child in the workspace.
    local torso = nil
    local dist = 1000 --Change range (in studs) here.
    local temp = nil
    local human = nil
    local temp2 = nil
    for x = 1, #list do --For every child in the workspace do
        temp2 = list[x]
        if temp2:IsA("Model") and temp2.Name ~= script.Parent.Name then --The child is a model and isn't a zombie.
            temp = temp2:findFirstChild("HumanoidRootPart") --Find the player's torso.
            human = temp2:findFirstChild("Humanoid") --Find the player's humanoid.
            if temp and human and human.Health > 0 then --The player is still alive.
                if (temp.Position - pos).magnitude < dist then --The player's torso is in the zombie's range.
                    torso = temp
                    dist = (temp.Position - pos).magnitude --Find the distance between the player and zombie.
end end end end
    return torso
end

wait(1)

while wait() do
    local target = findNearestTorso(script.Parent.Torso.Position)--Calls the function
    if target ~= nil then --If the character's torso still exists then
        script.Parent.Humanoid:MoveTo(target.Position, target) --Move the zombie to the player
    end
end

Note: Make sure the NPC is unanchored, otherwise it will not follow. Also, for future questions, be sure to code block your code by selecting over it and clicking the Lua button.
