What solutions have you tried so far? Did you look for solutions on the Developer Hub?

After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!

this is the first code is a module script

local ServerStorage = game:GetService("ServerStorage")
local PhysicService = game:GetService("PhysicsService")
local ServerStorage = game:GetService("ServerStorage")

local bindables = ServerStorage:WaitForChild("Bindables")
local updateBaseHealthEvent = bindables:WaitForChild("UpdateBaseHealth")

local mob = {}

function mob.Move(mob, map)
	local humanoid = mob:WaitForChild("Humanoid")
	local waypoints = map.Waypoints

	for waypoint=1, #waypoints:GetChildren() do
		humanoid:MoveTo(waypoints[waypoint].Position)
		humanoid.MoveToFinished:Wait()
	end

	mob:Destroy()

	updateBaseHealthEvent:Fire(humanoid.Health)
end

function mob.Spawn(name, quantity, map)
	local mobExist = ServerStorage.Mobs:FindFirstChild(name)

	if mobExist then
		for i=1, quantity do
			task.wait(0.5)
			local newMob = mobExist:Clone()
			newMob.HumanoidRootPart.CFrame = map.Start.CFrame
			newMob.Parent = workspace.Mobs
			newMob.HumanoidRootPart:SetNetworkOwner(nil)

			for i, object in ipairs(newMob:GetDescendants()) do
				if object:IsA("BasePart") then
					object.CollisionGroup = "Mob"
				end
			end

			newMob.Humanoid.Died:Connect(function()
				task.wait(0.5)
				newMob:Destroy()
			end)

			coroutine.wrap(mob.Move)(newMob, map)
		end

	else
		warn("Request mob does NOT exist!", name)
	end
end

return mob

the main script with the wave sistem that request all the module script

local ServerStorage = game:GetService("ServerStorage")

local bindables = ServerStorage:WaitForChild("Bindables")
local gameOverEvent = bindables:WaitForChild("GameOver")

local base = require(script.Base)
local mob = require(script.Mob)
local tower = require(script.Tower)
local map = workspace.SplitPath

local gameOver = false

base.SetUp(map, 500)

gameOverEvent.Event:Connect(function()
	gameOver = true
end)

for wave=1, 30 do
	print("WAVE STARTING:", wave)
	if wave < 3 then
		mob.Spawn("Mutant", 3 + wave, map)
	elseif wave == 3 then
		mob.Spawn("Sprinter", 5, map)
		mob.Spawn("Mutant", 5, map)
	elseif wave < 8 then
		mob.Spawn("Sprinter", 5 + wave, map)
		mob.Spawn("Mutant", 5 + wave)
	elseif wave == 8 then
		mob.Spawn("Sprinter", 5 + wave, map)
		mob.Spawn("Mutant", 5 + wave)
		mob.Spawn("Sponge", 7 , map)
	elseif wave < 12 then
		mob.Spawn("Sprinter", 5 + wave, map)
		mob.Spawn("Mutant", 5 + wave)
		mob.Spawn("Sponge", 1 + wave , map)
	elseif wave == 12 then
		mob.Spawn("Sprinter", 15, map)
		mob.Spawn("Mutant", 20, map)
		mob.Spawn("Sponge", 10, map)
		mob.Spawn("Monster", 1, map)
		
	
	end
	
	repeat
		task.wait(1)
	until #workspace.Mobs:GetChildren() == 0 or gameOver
	
	if gameOver then
		
		print("GAME OVER YOUR A NOOB!")
		break
	end
	
	print("WAVE ENDED")
	task.wait(1)
end

if you can find the solution or a possible solution i’ll be happy to hear it
have a nice day
