Can someone help me make the script for a radioactive lantern? [closed]

Ive used a find nearest torso script and edited it, but it wont do anything. No output in the script analysis

local larm = script.Parent:FindFirstChild("Left Arm")
local rarm = script.Parent:FindFirstChild("Right Arm")
local human = nil
function findNearestTorso(pos)
    local list = game.Workspace:children()
    local torso = nil
    local dist = 30
    local temp = nil

    local temp2 = nil
    for x = 1, #list do
        temp2 = list[x]
        if (temp2.className == "Model") and (temp2 ~= script.Parent) and game.Players:GetPlayerFromCharacter(temp2)~=nil then
            temp = temp2:findFirstChild("Right Arm")
            human = temp2:findFirstChild("Humanoid")
            if (temp ~= nil) and (human ~= nil) and (human.Health > 0) then
                if (temp.Position - pos).magnitude < dist then
                    torso = temp
                    dist = (temp.Position - pos).magnitude
                end
            end
        end
    end
    return torso
end




while true do
    wait()
    local target = findNearestTorso(script.Parent.Torso.Position)
    if target ~= nil then
        human:TakeDamage(10)
    end

end
