Object Oriented FPS Framework

Help and Feedback Scripting Support
#1

EDIT: Fixed

Hey DevForum, I’ve been learning how to use OOP (Object Oriented Programming) whilst scripting and decided to try and put it to use by making an FPS system.

The problem I’m having is that whenever I try to reference the :Aim() and :Unequip() function, it returns nil for some reason.

Handler module:

local Framework = require(game.ReplicatedStorage.Modules.Client.FPS.FPSFramework)
local UIS = game:GetService('UserInputService')
local Handler = {}

Handler.CanInitialise = true

function Handler:Init()
	local Player = game.Players.LocalPlayer
	local CurrentEquipped

	Player.Backpack.L119A2.Equipped:Connect(function()
		CurrentEquipped = Framework.new('L119A2')
		
		for i, Part in pairs (CurrentEquipped.Weapon:GetChildren()) do
			print('Looping through parts')
			if Part:IsA('MeshPart') or Part:IsA('Part') then
				print('checking if instance is part')
				Part.Transparency = 1
				print(Part.Transparency)
			end
		end

		UIS.InputBegan:Connect(function(Key)
			if Key.UserInputType == Enum.UserInputType.MouseButton2 then
				CurrentEquipped:Aim(true)
			end
		end)
	end)

	Player.Backpack.L119A2.Unequipped:Connect(function()
		CurrentEquipped:Unequip()
	end)
end

return Handler

Framework module:

local FPS = {}
FPS.__index = FPS

local RunService = game:GetService('RunService')
local TweenService = game:GetService('TweenService')
local Camera = game.Workspace.CurrentCamera
local NormalCF = CFrame.new()
local AimCF = CFrame.new()

function FPS.new(Weapon)
	local self = {}

	self.Config = require(game.ReplicatedStorage.Modules.Client.FPS.GunConfig)[Weapon]
	self. Viewmodel = self.Config.Viewmodel:Clone()
	self.Viewmodel.Parent = Camera
	self.Weapon = self.Config.Tool
	self.Shooting = false
	self.Aiming = false
	self.Reloading = false

	-- Rendering framework
	RunService.RenderStepped:Connect(function()
		NormalCF = NormalCF:Lerp(Camera.CFrame, 0.6)
		AimCF = NormalCF:Lerp((Camera.CFrame * CFrame.new(-1.2, 0.175, 3)), 0.9)
		if self.Viewmodel.Parent == Camera then

			-- Normal
			if self.Aiming == false then

				self.Viewmodel:SetPrimaryPartCFrame(NormalCF)

			-- Aiming
			elseif self.Aiming == true then

				print('aiming')
				self.Viewmodel:SetPrimaryPartCFrame(AimCF)
			end
		else
			return false
		end
	end)

	return setmetatable(self, FPS)
end

function FPS:Unequip()
	if self.Viewmodel.Parent == Camera then
		self.Viewmodel:Destroy()
	end
end

function FPS:Aim(Value)
	print('setting aim')
	self.Aiming = Value
end

return FPS

I have a localscript which runs the handler module, don’t worry about that

As you can see, I’ve place a bunch of prints in order to see where it goes wrong. I’m sure this is an easy fix but I’ve been looking everywhere and can’t find anything that helps. I have this same problem with another OOP system I tried making whilst learning how to use OOP so if you guys have a fix it would be very appreciated, thanks.
