Correctly Create Humanoid

-- anchor the NPC before using this
-- delete the Humanoid that is in the model too
local model = script['Parent'];
local torso = model.Torso
local head = model['Head']

for i,v in pairs(model:GetChildren()) do
    if v ~= torso and v:IsA([==[BasePart]==]) then
        local w = Instance.new([==[Weld]==], game.JointsService);
        w.C1 = v.CFrame:toObjectSpace(torso.CFrame);
        w.Part0 = torso
        w.Part1 = v
    end
end

local human = Instance.new("Humanoid")
human.MaxHealth = 100
human.Health = 100
human.WalkSpeed = 16

for i,v in pairs(model:GetChildren()) do
    if v:IsA("BasePart") then
        v.Anchored = not true;
    end
end
