How should I make a Tower Defense type movement system?

[Azurethpat (the man)]

I am currently comtemplating on how I should crate a TD-esque moment system.

First, I’m curious on what I should do to move the enemies. Should I use tweens? Should I use lerping?

Where should I be rendering the movement, on the client or server?

How can I make smooth turns?

Any help is greatly appreciated

You can create bezier curves. They’re a type of spline which only require three parts to create a smooth curve. You can use this module to create bezier curves easily.

Thanks! I am still confused mainly how I should render the movement & how I should actually move the enemy/rig.

humanoid:MoveTo(waypoint.Position) is what you are looking for

[Azurethpat (the man)]

I have heard of this, but I believe Humanoids can be a drag on performance. Thanks for the suggestion!

[Flumzee]

No, that is unoptimized and looks bad.

You can use a rendering system called client-sided rendering.

How would I access whether an enemy or such has entered the base? Using RemoteEvents could be easily manipulated.

Would I use tables to store data about the enemy?

This is currently my script for spawning enemies :

--// Services
local S_RS = game:GetService("ReplicatedStorage")

--// Constants
local COMMON = S_RS:WaitForChild("Common")

local RESOURCES = COMMON:WaitForChild("Resources")
local ENEMIES = RESOURCES:WaitForChild("Enemies")
local MODELS = ENEMIES:WaitForChild("Models")
local CONFIG = ENEMIES:WaitForChild("Config")

local ENUMS = require(COMMON:WaitForChild("Enums"))

--// Variables
local enemies = {}

--[[PRIVATE]]--



--[[PUBLIC]]--

function ENEMY.spawn_enemy(enemy_name: string, map, count: number, interval: number, start_delay: number): ()
	
	assert(enemy_name, "Enemy name was not given, enemy name is required to spawn the enemy.")
	
	local enemy_exists = MODELS:FindFirstChild(enemy_name)
	
	assert(enemy_exists, "Enemy model was not found or not loaded.")
	assert(enemy_exists.PrimaryPart, "Enemy model does not have a PrimaryPart.")
	
	assert(count, "Count was not given, a required argument.")
	assert(interval, "Interval number was not given, a required argument.")
	assert(start_delay, "The Start Delay number was not given, a required argument.")
	assert(map, "Map was not given, a required argument.")
	
	task.wait(start_delay)
	
	for enemy_count = 1, count, 1 do
		
		local enemy_model = enemy_exists:Clone()

		local enemy_config = require(CONFIG:WaitForChild(enemy_name) or CONFIG:WaitForChild("Default"))

		assert(enemy_config, "Enemy config was not loaded or not found.")

		local enemy = {}

		enemy.HEALTH = enemy_config.HEALTH
		enemy.CONFIG = enemy_config
		enemy.ENUM = ENUMS.ENEMIES[enemy_name]

		enemy.ENEMY = enemy_model.PrimaryPart

		enemies[enemy_model] = enemy

		enemy_model.Parent = workspace:WaitForChild("Enemies")
		
		task.wait(interval)
		
	end
	
	print(enemies)
	
end

return ENEMY

This is made for the Server

[Flumzee]

Basically what you do is you fire the properties of a table;

local table = {
["health"] = 3
["cframe"] = CFrame.new(...),
["speed"] = 3
}

and then you use a model from the client side that you clone and use those properties to change the enemy.

[Azurethpat (the man)]

Oh, I understand. I think my current spawning system uses a similar idea.

[Flumzee]

You can use _G.database = {[enemies here]} on the server side.

[Azurethpat (the man)]

I’ll do some research into Client Sided rendering.

Okay, good luck creating your future tower defense!

Thanks for helping! I really appreciate your contribution.

You’re welcome, good luck with your tower defense game. Also, there was somebody on YouTube doing exactly what you are looking for, you can also message him, @samuelissad, about this topic, but unfortunately stopped the videos.
