Wave Based Attacks - Tower Defense Tutorial #2 

I like how he doesnt just create tutorials and tell you how to do things... he teaches you as well and shows you common mistakes people do. thats awesome

Omg this has been such an adventure I'm starting to get the hang of scripting in Roblox studio, but you have been there for me forever almost I've been watching videos like these forever thank you so much for helping everybody with these videos!

To everyone who's mobs arent spawning: 1. Check if you have a map folder. In this video, the folder name is "Grassland" and there should be 3 main things inside: "Path" folder, "Waypoints" folder, and "start" object. 2. Check if you have "start" in your "Grassland" or map folder. The "start" object can be anything. 3. Check if you put the "zombie" or enemy inside a "Mobs" folder in the ServerStorage.

I like these kinds of videos cause i can see the progress from a simple baseplate to a functioning game, im not even a developer

ive noticed i actually started to understand how to code, this series made me wanna start making games and i when i tried i just copied the code he gave me and had no idea what to do, these days i actually understand what they do which is making me proud

started to play alot of td games so thanks to your td tutorial series I might be able to make my own! :D

Thank you so much GnomeCode, you have one of the best tutorials to make TD games. This all worked all because of you Thank you so much!!

I love how its really basic and easy to learn, i love it

I love these tutorials! Please continue uploading videos like these.

U need more subs man, this stuff is so helpful

This took me 30 min so here: Mob Script: local ServerStorage = game:GetService("ServerStorage") 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() end function mob.Spawn(name, quantity, map) local mobExists = ServerStorage.Mobs:FindFirstChild(name) if mobExists then for i=1, quantity do task.wait(0.5) local newMob = mobExists:Clone() newMob.HumanoidRootPart.CFrame = map.Start.CFrame newMob.Parent = map.Mob coroutine.wrap(mob.Move)(newMob, map) end else warn("Mob not found:", name) end end return mob Main Script: local mob = require(script.Mob) local map = workspace.Your map --- Put your map name. for wave =1, 5 do print("WAVE STARTING:", wave) if wave < 5 then mob.Spawn("Zombie", 3 * wave, map) elseif wave == 5 then mob.Spawn("Zombie", 100, map) end repeat task.wait(1) until #map.Mob:GetChildren() == 0 print("WAVE ENDED") task.wait(1) end

genuinly this is the best tuturial ever

2:15 map script full build 2:48 main script full build 4:36 main script full build part 2 6:16 mob script full build 7:17 mob script full build part 2 9:39 mob script full build part 3 10:08 map script full build part 2 10:50 mob script full build part 4 12:19 mob script fix full build 13:19 bit change of mob script 13:42 map script fix change 14:32 bit fixes 14:46 changed map script 16:34 map script part 3 18:32 wave script fixed

You are a really good coder keep up the good work!

This series deserves a sub :)

If the walking path is messed up by having a different walkspeed, just put another waypoint before the waypoint that you are having trouble with.

Without this guy I wouldve probably failed making a tower defense game

I and others appreciate you taking your time to do all of this GnomeCode, you're a godsend man.

Best tutorial i ever seemed

I took days and it didn't spawn

my friends are trying to make a tower defense game after tower battles is being discontinued. thank you for this awesome series !

Your incredibly easy to follow along, thank you!

i have a question, when i got to the part where the part spawns in the zombies, it always says your module experienced an error while loading, can someone help me?

Great Series! (Subscribed after first video!)

Woah, this is nice; i'm new to scripting and i always wanted to make a td game for like 7 months but never actually finished / released any of them, i tried 2 times and discontinued the first one because i was stuck on the wave system, thanks a lot for this video

Hey GnomeCode love this series so far. I have noticed the zombie does not spawn in the spawner and I see I am not the only person with this problem. If you could make a updated version or comment back the newer script that would be great! Thank you. :)

The coroutine is giving me error messages and I cannot figure out how to fix it. Ive tried looking into coroutines online and even if ive read the solution my implementation of it did not fix. is there anywhere else i could go to get assistance? the error message is " invalid argument #1 to 'wrap' (function expected, got nil) "

Thanks so much! it helped alot

I love how u cleanly coded everything! Just perfection!

really helpful, this entire tutorial so far has been going great and it looks very promising, and everything works really well. Thanks!

Man, this guy is very good tutorial maker😇

Can anyone help me with something? Instead of the zombie model I used an normal rig I did everything but when I test it it says to the output "InsertService cannot be used to load assets from the client" pls someone help me, i am new and i have no idea what do i have to do.

really high quality tutorial and i learnt a lot. Also his basic tutorial is really in depth

10:06 saving my time, Awesome tutorial!

i never noticed the orientation indicator! Thats gonna be so useful for some upcoming games!

This series is really great! Unlike other tutorials, when I run into issues, I can fix them easily! Not only that, your explanations and scripts are really simple and easy to understand.

At line of code 23 in the Enemies(aka Mobs) module script it tries to call a NIL value, I have tried to change it so many times and it just doesn't work. Could you please help me? Also I replaced mob with enemy (The Code is: enemy.Move(enemy, map))

My Error says Requested mob does not exist ▼ { ["Move"] = "function", ["Spawn"] = "function" } - Server - Mob:22 please help!

my scripts are fine but for some reason nothing will spawn. i rewrote the script and made sure to not misspell anything but it still didn't work, can some one help me?

I need help, in main when I put “wave, map” it says, “Argument count mismatch. Function ‘mob.Spawn’ expects 0 to 2 arguments, but 3 are specified. Any help?

Gnomecode when you will make the lobby of this td tutorial? Like how to make a shop for buying towers you get it if you played tower battles or other tds game in roblox Edit: i never got 9 likes on a comment, thanks

Yo GnomeCode part 1 was not Hard and i liked that but Part 2 uhhh it shows me an error is there any way u could help me fix it it says ' ServerScriptService.Main.Mob:9: attempt to index nil with 'CFrame' i really wanna make a Tower defence game but thanks for the tutorials they really help me

its awesome how instead of just telling you what code to write he shows what mistakes people make and how to improve them

Noah's Archive recommended you during a stream to help me script my game, I'm not disappointed. Thank you alot for teaching me how to script

idk why the zombies not spawning is there any ideas how to spawn it ?

tysm bro after i do this game i will wach other tutorials!!

I love your tutorials, they are very helpful, and help me learn to script!

i tried following along and apparently the script tries to index nil on start because my model does not have a humanoidrootpart inside so i thought i could substitute that with a part that already exists on the modele (ex.torso) instead (fixed by adding in a humanoidrootpart, however now it doesn't exist)

Umm can anyone help me, I dont know if I missed a step but after I ran it at the end of the video the mobs wouldnt appear the backround like the grass and the trees looked nice but the mobs just didnt appear im really wondering why please help!

@GnomeCode the enemy wont spawn and i have an error code that is saying "ServerScriptService.Main:1: attempt to call a nil value" How do i fix this?

Amazing job on the tutorials, Keep the amazing work up!

It's normal that at 10:50 I have the same code as you but it don't wants to move ? I did this with another mob. So It's correct or not ?

Hey GnomeCode, i was trying to do your tutorial, but when i played the map no zombies spawn how do i fix it?

when he calls me a fellow gnome it makes me happy

I’ve really enjoyed this series… It will really help my tower defense game. If I ever need help this is definitely the channel. Thanks GnomeCode!

I get either the output “attempt to index nil with start” or “attempt to index nil with CFrame”. Please help because I am trying to work on a tower defense game with a team and we cannot move on until the enemy spawns and is moving.

the best teacher in whole world, i love your videos. You making amazing job

I love playing tds games and this was the only one that was clear and helpful to make one, so thank you for helping.

10:10 my zombies dont spawn bro, like not even 1 zombie. What seems to be the issue?

Hi @GnomeCode, this series is great and have been working for me till episode 2#. I did everything you said with thie wave part, but the output always says "Requested module experienced an error while loading" when i run the game. It would be really helpful if you either commented how to fix it, or anyone else the solution to this. Thank you for reading TheGreenDino

i need help because when making the enemy move i followed all ur instruction but the enemy is still not moving

You're great at explaining things. I'm very interested in scripts regarding combat. So far I've been using RED Plys to learn how to make a combat script, but I feel his tutorials are very hard to follow for someone who's still trying to learn. I would like to know if you ever plan on making a tutorial on combat. If you do can you make a combat script similar to RED Plys?

Does this still work? I got everything working up to the part where you get the mobs to move after being spawned. I checked everything in my scripts over ten times and I have everything right but the zombies still aren’t moving after spawning.

I am having problems with destroying the mobs, since when they reach the end an error pops up saying that my waypoint could not be found, and it makes it so it doenst destroy the mob. Does anyone got a solution to this? Fixed it: there were actually 13 waypoints instead of 12

I think i messed my walking script up because the zombie doesn't move and it says error cloud_11663072354, but u dint know how to fix it

At some point in this series (probably the last epsiode) you could show how to make multiple maps and a way to choose which map you join (the two most common being matchmaking or elevators) aswell as other QoL features like wave skipping. Thanks Gnome! P.S. If your looking for reference, I would recommend Tower Battles, Tower Defense Simulator or Tower Blitz.

How do i make models without the humanoid part move around the track?

Nothing won’t spawn in I checked the script if I had a script error but everything was fine and I did all of the things you said. Please does anybody know how to fix this?????

10:46 When I do that script my zombie doesn't move, and it just spawns a zombie in workspace and deletes when I exit run. I'm not sure how to fix It due to my lack in coding, please help me.

hey just some suggestions for things that would be good for a full on tower defense game Money that you can spend on towers and upgrading them in game (obviously) Towers that can be upgraded (of course) (5 different levels could be good enough, and them changing appearance based on what level they are would be cool too) A Farm tower (something that would give you different amounts of money per wave) A support tower (like the DJ in TDS, providing buffs to the towers nearby it, and the perks getting better as they upgrade, like a small discount for upgrading) Tower skins (things that would reskin your tower but still do the same thing) A lobby, where you can go into an elevator or something to start a round, and also equip your different towers. Also just something i think would be cool Different enemies that would spawn depending on what map is chosen, like a swamp map would spawn swamp monsters, they'd all be the same at the end of the day just look different I dont expect most of these to get in because they might be kinda complicated

i have an error.. Postion is not a valid member of Part "Workspace.Grasslands.waypoints.1" im sure i did everything right seems not any help?

When yours doesn't work but you still support the creator for making awesome content and helping other people so you subscribe

bro it works LOL and it looks so fun!

gnomecode ive been following your account and its awesome but i have problem, whenever i finished and tested it and the zombies were spawning in groups like you said, but they werent moving inside of the red forcefield (the start) and i just wanted to know if you can pls PLS help me how to fix this, i tried to find the bug but i cant find it, they just wont move and go to the waypoints:(

Hey! I love scripting and im trying to learn as much as possible and this really helps me get inspiration and gets me more into developing! Thank you so much for every video! Right now I'm trying to learn CFrames a bit more. Great video though! Keep up the good work! Gnome Gang Forever! Edit: Fixed some missspells.

Solve from zombie spawn: if module script is named Mob name all the mob Mob with cap M like this: local ServerStorage = game:GetService("ServerStorage") local Mob = {} function Mob.Spawn(name, map) local MobExists = ServerStorage.Mobs:FindFirstChild(name) if MobExists then local newMob = MobExists:Clone() newMob.HumanoidRootPart.CFrame = map.Start.CFrame newMob.Parent = workspace else warn("Requested mob does not exist:") end end return Mob you can copy and paste that

10:48 when I add this line of code, I get an error reading 'Mob:9: Humanoid is not a valid member of Humanoid "Workspace.Enemies.Enemy.Humanoid"' and only when I add that line. can someone please help? [EDIT] nevermind, I fixed it. If you have the same issue, replace the mob.Move function with this: function mob.Move(mob, map) local humanoid = mob:WaitForChild("Humanoid") local waypoints = workspace.Waypoints for waypoint=1, #waypoints:GetChildren() do humanoid:MoveTo(waypoints[waypoint].Position) humanoid.MoveToFinished:Wait() end end

hey Gnome, i did everything right, i did the same exact stuff as you did , copied everything but yet the zombies don't spawn in, can you please explain why they don't spawn???

you can also animate the enemies through the module so you dont have to make animate script for every enemy

at 0:42 for him it shows service script but dosent for me on roblox studio. why is this?

when i do coroutine part it says ServerScriptService.Main.Mob:23: Expected ':' not '.' calling member function MoveTo may i get some info or help?

I have a problem where if I delete the mobs in the workspace, they still exist but are just invisible. The round does not stop and it goes until the invisisble mobs reach the end. Help?

This is awesome Gnome!! How many episode do you think this series will be or is it unknown right now?

I need help I rewrote the script and checked it over (the mob one) and the zombies still aren’t moving I need help I’m desperate plz

it says Requested module experienced an error while loading. in ServerScriptService but i literally have the same scripts, maybe its outdated? idk can you help

Hey when i tried to run to spawn the zombies it said "attempt to index nil with 'start' " how to fix?

If you're zombie isn't moving there is a possibility that you missspelled or missplaced a folder or model. if you're getting "Waypoints is not a valid member" error. you might have misspelled your "Waypoints" like i did or misspelled you're map

Listening to the output really does help when something is broken. May take a couple of minutes to find the problem.

I dont think this works anymore evey time i do it even if i copy it 1:1 i does'nt work i keep getting errors like attempt to index nil with 'CFrame' and the zombie wont spawn

Help me when I’m writing a script and zombies don’t spawn and there’s no error, what should I do?

if at 10:40 the mob doesnt move when spawned change function mob.Move(mob, map) local humanoid = mob:WaitFirstChild("Humanoid") local Waypoint = map.Waypoints for waypoint = 1, #Waypoint:GetChildren() do humanoid:MoveTo(Waypoint[waypoint].Position) humanoid.MoveToFinished:Wait() end to function mob.Move(mob, map) local humanoid = mob:FindFirstChild("Humanoid") local Waypoint = map.Waypoints for waypoint = 1, #Waypoint:GetChildren() do humanoid:MoveTo(Waypoint[waypoint].Position) humanoid.MoveToFinished:Wait() end Your welcome

My script isn't spawning in 3 zombie it only spawns 1 and I followed the instructions perfectly.

can anyone please explain to me why the first script that prints out the name and map isnt working? the error in the output is ServerScriptService.main:3: attempt to index nil with 'spawn'

please please help! i have "mobs" folder in serverstorage and in "mobs" folder there is a zombie but when i test the game in output there is a "Requested mob does not exist: Zombie". HOW TO FIX IT!!!!!!

its all working but i got a problem with waypoints, the zombies doesnt follow it at all cause at last waypoints it doesnt go straight to the end

8:00 when i try to run the game, the mob doesn't spawn and says "Requested module experienced an error while loading" - Server - Main:1 how do i fix this?

the zombies dont move but clone straight away and cant collide with eachother please tell me how fix it GnomeCode

The problem with "attempt to index nil with "CFrame" is that in the main script change the name from "Grasslands map" to map and make sure CFrame is spelled with large C and F and put the Start inside the grasslands folder.

Why doesnt my zombie spawn pls help

Tysm I'll make sure to add credits
