Rbx Lua Classes can't grab models?

The error is that the values assigned in the new method are nil to other methods of the class. How can I have the values not be nil when a method requests for them? As when I spawn a NPC and ask for the CFrame, it states self is nil.

01local NPC= {}
02NPC._index = NPC
03 
04function NPC.new(model)
05    local entity = setmetatable({}, NPC)
06    for index, value in pairs (NPC) do
07        entity[index] = value
08    end
09    entity.Self = model
10    entity.Settings = model:WaitForChild("Configurations")
11    entity["Mind"] = model.Mind
12    return entity
13end
14 
15function NPC:GetCFrame()
16    local humanoidRootPart = self.Self:FindFirstChild("humanoidRootPart")
17    if humanoidRootPart and humanoidRootPart:IsA("BasePart") then
18        print(humanoidRootPart.CFrame)
19        return humanoidRootPart.CFrame
20    else
21        return CFrame.new()
22    end
23end

25function NPC:Initialize()
26    NPC:GetCFrame()
27end

The issue was - shockingly - due to the the metatable being set incorrectly. It was: setmetatable(NPC, {}) which causes the methods to be able to grab their own values.

So 'entity' was set wrong? Just clarifying, I am personally trying to learn how to use metatables. TheDeadlyPanther 2460 — 8y
