Problem with oop class

[Animatedbeta1 (AnimatedZY)]

I was making a tycoon game to learn more aout oop programming but I’ve got a issue, I wanted to see if the tycoon has already a owner, but the problem is that all the tycoons are “connected” so if one tycoon has a owner the script will interpretate that as if all the tycoons have already a owner, here’s the module script:

--Define the class Tycoon
local Tycoon = {}
Tycoon.__index = Tycoon

--Constructor of the class Tycoon
function Tycoon.create()
	self = setmetatable({},Tycoon)
	return self
end

--Analise if the tycoon has a owner 
function Tycoon.new(player,Tycoon)
	if self.Owner == nil then
		self.Owner = player
		self.Name = Tycoon
		print(self.Owner.Name .. " is owner of " .. self.Name)
	else
		print(self.Name .. " is alread taken by " ..self.Owner.Name )
	end
end

return Tycoon

The main script

Tycoon = require(game:GetService("ServerScriptService").Tycoon)
part = script.Parent

Tycoon.create()

part.Touched:Connect(function(hit)
	if hit.Parent:IsA("Model") then
		local char = hit.Parent
		local Player = game:GetService("Players"):GetPlayerFromCharacter(char)
		local InitialTycoon = Tycoon.new(Player,"Initial")
	end
end)

I already tried to pass a table as a argument in the Tycoon.create() function and the only idea i have to fix it is to make a Module Script for every tycoon but that is not very efficient.

Your Tycoon.create function returns the object, you must save it in a variable for this to be useful

local Initial = Tycoon.create()

To use self in a method you must define the function with a colon like so

function Tycoon:new(player)

Now using the method with our object the same way will yield different results for each object.

part.Touched:Connect(function(hit)
	if hit.Parent:IsA("Model") then
		local char = hit.Parent
		local Player = game:GetService("Players"):GetPlayerFromCharacter(char)
		local InitialTycoon = Initial:new(Player) -- using method
	end
end)

It may also be helpful to look into the CollectionService so you don’t have to copy this script into each tycoon object. But I hope this has helped you with OOP in lua, it is kind of weird compared to other languages!

It worked thank you, but let me see if I’m getting this straight, with the “Initial = Tycoon.create” i’m defining Initial as a variable for table that I created but what’s the difference between a point and a colon? ty one more time.

@Animatedbeta1

but what’s the difference between a point and a colon?

The reference to self, when the function uses a dot it does not reference the self.

function Tycoon.new()
--here self is nil
end

function Tycoon:new()
--self is Tycoon:{}
end

Edit: Although it is essentially the same as doing

Tycoon.new(Tycoon)

Thanks bro, so when I use a colon the function will take the word before the colon as a parameter, while with the dot the function will take the table tycoon has a parameter, right?

@Animatedbeta1

while with the dot the function will take the table tycoon has a parameter, right?

If by this you mean that the function will only take the table tycoon as parameter if you willingly give it as a parameter then yes, all of that is true.

The reason why you would use self and colons is because when you create a new “Tycoon” object, by using self you are referencing that newly created tycoon object’s table, instead of the original template table it comes from.

Okay, so I understand now, ty!
