Attempt to call nil value on "self"?

Help and Feedback Scripting Support
#1

I was trying to make a part clone by using OOP, while trying to get it I came across an error. I think “self” is nil. Here is the script:

local Object = {}
Object.__index = Object

function Object.new(position,part)
	local newobject = {}
	setmetatable(newobject,Object) 
	
	newobject.Position = position
	newobject.Part = part
	
	return newobject
end

function Object:Spawn()
	local clone = self:Clone()--Error lies here, "attempt to call a nil value"
	clone.Parent = game.Workspace
end

return Object

Main script:

Object = require(game.ServerScriptService.ModuleScript)
local part = game.ServerStorage:FindFirstChild("Part")

newobject = Object.new(Vector3.new(0,0,0),part)
newobject:Spawn()

You’re trying to call clone on a table? It should be
self.Part:Clone()

Are you trying to clone the part in that OOP? if so, self.Part:Clone() as @Pokemoncraft5290 said before me haha. You can’t clone self

It works now. Thank you. But why do I have to include, self.Part?

Because you were tryign to use :Clone() on a table instead of the Part that you wanted to clone

Now I understand. Thank you. Also when the part is cloned the position isn’t at 0,0,0. Any reason for that?

Probably because you stored the position in the table yet you never use it, I think you wanted to do

function Object:Spawn()
	local clone = self.Parent:Clone()
	clone.Parent = workspace
	clone.Position = self.Position
end

For the Spawn function to spawn the Part clone at the position in the Object

Anytime! If you have anymore issues don’t be afraid to make another post!

Also I recommend you mark @Pokemoncraft5290’s first reply to your post as the solution as he was the first one to answer the original problem in your post and rightfully deserves it
