How to make a "replication buffer"?

#1

I have a very barebones character replication system that I am working on because it is for a game that I plan to implement custom replication for. I’ve heard about using a replication buffer system and how it actually works, basically a system that allows me to use future positions of the character that I can use that if a small fluctuation in ping occurs and other stuff.

I am mainly looking for advice on how I can implement this, this is what my current system looks like

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local TweenService = game:GetService("TweenService")
local Players = game:GetService("Players")

local replicateCharacterRemoteEvent = ReplicatedStorage.Events.RemoteEvents.ReplicateCharacter

local localPlayer = Players.LocalPlayer
local humanoidRootPart

local UPDATE_RATE = 0.05

task.spawn(function()
    while task.wait(UPDATE_RATE) do
        if humanoidRootPart then
            replicateCharacterRemoteEvent:FireServer(humanoidRootPart.Position, humanoidRootPart.orientation, humanoidRootPart.AssemblyLinearVelocity)
         end
     end
end)

localPlayer.CharacterAppearanceLoaded:Connect(function(character)
    if character.HumanoidRootPart then
        humanoidRootPart = character.HumanoidRootPart
        if humanoidRootPart.Anchored == true then
            humanoidRootPart.Anchored = false
        end
        humanoidRootPart:GetPropertyChangedSignal("Anchored"):Connect(function()
            if humanoidRootPart.Anchored == true then
                humanoidRootPart.Anchored = false
            end
        end)
    end
end)

replicateCharacterRemoteEvent.OnClientEvent:Connect(function(player, position, orientation, assemblyLinearVelocity)
    if player.Character then
        if player.Character.HumanoidRootPart then
            local predictedCFrame = CFrame.new(position + assemblyLinearVelocity * UPDATE_RATE) * CFrame.Angles(math.rad(orientation.X), math.rad(orientation.Y), math.rad(orientation.Z))
            TweenService:Create(player.Character.HumanoidRootPart, TweenInfo.new(UPDATE_RATE, Enum.EasingStyle.Linear), {CFrame = predictedCFrame}):Play()
        end
    end
end)
