Confused about what I'm exactly doing when making OOP classes

Heya There!!

I’m rewriting my entity system once again with Composition and OOP Classes in mind. The issue is that I don’t know what I’m doing. There are two module scripts named EntityClass (Which, from my knowledge, is the superclass) and SubclassEntity. What I’m trying to do is that I want EntityClass to be the base of the subclass module, containing things such as the spawn and despawning of entities alongside basic movement stuff like pathfinding.

On the other hand, I’d also want SubclassEntity to house specific functions exclusive to that module such as attacking alongside using the functions from EntityClass.

EntityClass

--[[MODULE]]--
local EntityMoodule = {}
EntityMoodule.__index = EntityMoodule

function EntityMoodule:CreateEntity()
	local self = {}
	
	--//TBA
	
	return setmetatable({}, EntityMoodule)
end

return EntityMoodule

SubclassEntity

--[[BASE CLASS/SUPERCLASS]]--
local EntityClass = require(script.Parent)

--[[MODULE]]--
local SubclassEntityModule = {}
SubclassEntityModule.__index = SubclassEntityModule
setmetatable(EntityClass,SubclassEntityModule)

function SubclassEntityModule:NewEntity()
	--//TBA
end

return SubclassEntityModule

What you want to do wouldn’t be something like that instead?

local SubclassEntityModule = {}

setmetatable(SubclassEntityModule, EntityClass)
3

What do you mean by that? Clarify, please.

If you are doing EntityClass as the superClass, you would set EntityClass as the metatable for Subclass, right? So when Subclass doesn’t find a function inside of itself, it will try search inside Entityclass, but I don’t think that’s what you want to do.

Though why do you want to make a subclass and superclass system? Why not making it only one OOP?

6

The reason why I’m using a class-based system instead of putting them all together is that I’m planning on making two subclasses, those being a Melee and Ranged class. Of course, you already know what those classes might be about.

Do you mean like inheriting from EntityClass?
If so then

local EntityClass = require(script.Parent)

local SubclassEntityModule = setmetatable({}, EntityClass)
SubclassEntityModule.__index = SubclassEntityModule

function SubclassEntityModule:NewEntity()
    local self = setmetatable(EntityClass:CreateEntity(), SubclassEntityModule)

    return self
end

return SubclassEntityModule

(I’m stupid and don’t understand your question so this might be 100% off topic sorry)

Something like that, yeah. Thanks for the help!
