Anything i could improve inside my game framework module?

So for the funs i decided to try to make a game framework module to practise my OOP skills. I started out with a simple module. Basically all i have atm is just a method in my module called “RunFunc()” which you can bind stuff to. Such as a schedule n stuff.

All i want to know is if my module is efficient enough or if theres anything that can be improved/changed??

How it looks like inside a normal script. Two examples. Also the arg after the functions on “RunFunc” are the ids for the task/schedule(Atm the ids doesnt really do that much):

local Framework = require(script.Parent.Framework)




local A = Framework:RunFunc(function()
	print("Schedule 1")
end,1):ScheduleFunc(5)




local B = Framework:RunFunc(function()
	print("Schedule 2")
end,2):ScheduleFunc(5):WaitAndThen(1):CancelSchedule()

Framework module:

local Framework = {}


local Scheduler = require(script.Scheduler)



function Framework:RunFunc(Func,Id)
	if Id then
		return Scheduler.new(Func,Id)
	else
		Func()
	end
end



return Framework

Schedule module:


local Scheduler = {}
local FuncsInSchedule = {}

Scheduler.__index = Scheduler


local WaitModule = require(script.Parent.Wait)




-- // Others
local NewThread = task.spawn
-- // End



function Scheduler.new(Handler,Id)
	return setmetatable({_Func = Handler,FuncId = Id},Scheduler)
end



function Scheduler:ScheduleFunc(Time: number)
	local NewWait = WaitModule.new()
	
	
	NewThread(function()
		NewWait:Wait(Time)
		self._Func()
		self = nil
	end)
	
	return setmetatable({Timer = NewWait},Scheduler)
end




function Scheduler:WaitAndThen(Time)
	WaitModule.new():Wait(Time)
	return setmetatable({Timer = self.Timer},Scheduler)
end



function Scheduler:CancelSchedule()
	self.Timer:CancelWait()
	self = nil
end


return Scheduler
