RaycastHitbox melee server-sided check issue

Help and Feedback Scripting Support
#1

I am using the RaycastHitbox module for my melee system, and I’m doing the raycasting on the client and doing damage on the server, but how can I add a server-sided check to detect to make sure they are not attacking too fast without making the melee only hit one target per swing?

Client

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

local RaycastHitbox = require(ReplicatedStorage.Modules.RaycastHitboxV4)

local localPlayer = Players.LocalPlayer
local character = localPlayer.Character or localPlayer.CharacterAdded:Wait()

local container = script.Parent
local tool = container.Parent
local toolRemotes = tool.Remotes

local Configuration = require(tool.Configuration)

local hitRemote = toolRemotes:WaitForChild("Hit")

local raycastParams = RaycastParams.new()
raycastParams.FilterDescendantsInstances = {character, tool}
raycastParams.CollisionGroup = "IgnorePlayers"
raycastParams.FilterType = Enum.RaycastFilterType.Exclude
raycastParams.IgnoreWater = true

local raycastHitbox = RaycastHitbox.new(tool.Handle)
raycastHitbox.RaycastParams = raycastParams
raycastHitbox.Visualizer = true

local function onActivated()
	raycastHitbox:HitStart(Configuration.ATTACK_DURATION)
	task.delay(Configuration.ATTACK_DURATION, function()
		raycastHitbox:HitStop()
	end)
end

local function onHit(hit: Instance, humanoid: Humanoid)
	hitRemote:FireServer(hit, humanoid)
end


tool.Activated:Connect(onActivated)
raycastHitbox.OnHit:Connect(onHit)

Server

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

local validateHit = require(ReplicatedStorage.Modules.Utility.validateHit)

local container = script.Parent
local tool = container.Parent

local Configuration = require(tool.Configuration)

local lastHit = os.clock()

local function onHitEvent(playerThatFired: Player, hit: Instance, humanoid: Humanoid)
	if not validateHit(tool, playerThatFired, hit, humanoid) then
		return
	end
	if math.abs((os.clock() - lastHit)) < Configuration.ATTACK_DURATION then
		warn("Min")
		return
	end
	humanoid:TakeDamage(Configuration.DAMAGE)
	lastHit = os.clock()
end

tool.Remotes.Hit.OnServerEvent:Connect(onHitEvent)
