How to make my interact system more efficient?

I am making an interacting system, and I created the basic Interact system, how do I make it more efficient?

-- Local Script
local main = require(game.ReplicatedStorage.Resources.Modules.Shared.MainFramework)
main:setupScript() -- this is just to make the Services table work for my game.
local userInputService = game:GetService("UserInputService")
local runService = Services.RunService
local players = Services.Players
local localPlayer = players.LocalPlayer
local KEYBIND_FOR_INTERACTION = Enum.KeyCode.E
local debounceforTween = false
local deb = false
local function tweeninandout()

end
local remoteEvent = Services.ReplicatedStorage.Resources.Events.OnInputDetected
local function onInputBegan(...)
    for _, interactive in ipairs(workspace.Interactives:GetChildren()) do
        if interactive:FindFirstChild("IsInteractive") then
            local Character = localPlayer.Character
            if Character then
                local humanoidRootPart = Character:FindFirstChild("HumanoidRootPart")
                if humanoidRootPart then
                    if Character:FindFirstChildWhichIsA("Humanoid").Health <= 0 then
                        break
                    else
                        local magnitude = (interactive.Position - humanoidRootPart.Position).magnitude
                        if magnitude <= interactive.IsInteractive.Range.Value then
                            local b = tweeninandOut()
                            if b then
                                return
                            end
                            remoteEvent:FireServer(interactive)
                        end
                    end
                end
            end
        end
