Can you make another video like this but with a more advanced ai? (e.g moving around parts) It would really help!

[@silkesolke]

Is this for r6 too??

How to put script in description of a devmelon video tutorial

[@JumpyMan204]

Yeeeeeee NICE VIDEO!

[@The_Ace_Debate]

how do you make it to where it only chases you when in a certain range

[@BlueWithaFruit]

script:
local NPC = script.Parent
local HumanoidRootPart = NPC.HumanoidRootPart
local MaxDistance = math.huge
local debounce = false
NPC.Humanoid.Touched:Connect(function(hit)
if hit.Parent:FindFirstChild("Humanoid") and not debounce then
debounce = true
hit.Parent.Humanoid.Health -= 20
wait(1)
debounce = false
end
end)
while wait() do
local Players = game.Players:GetPlayers()
local closest
for i, plr in pairs(Players) do
if plr.Character and plr.Character:FindFirstChild("Humanoid") and plr.Character.Humanoid.Health > 0 then
local PlayerHumanoidRootPart = plr.Character.HumanoidRootPart
local Distance = (HumanoidRootPart.Position - PlayerHumanoidRootPart.Position).Magnitude
if not closest then
closest = PlayerHumanoidRootPart
end
if (HumanoidRootPart.Position - closest.Position).Magnitude > Distance then
closest = PlayerHumanoidRootPart
end

end
end
if closest and (HumanoidRootPart.Position - closest.Position).Magnitude

Ty so much this will help me a lot with the game that I'm making!❤

[@WhartonProject]

Can you make it so you get a leaderstat/variable when you kill it

[@greemp]

devmelon thank you and i subscribe you. can you make a video about the hiding system from the enemy?

[@JumpyMan204]

hey man i just came here to tell u that u that ur videos are useful, funny, and informative 🤓🤓🤓 but jokes aside u actually need more than 1.9k subs

[@devmelonroblox]

Thanks

[@TizianoNicolasGamer100]

looking good, devmelon but it's better when it has attack animations so the enemy npc would be epic.

[@Tuxedox]

w video bro keep it up

[@devmelonroblox]

Thanks!

[@TTVtreekoVr]

Pleaseee, your videos are amazing but I had problems with this one, I used a rig from the toolbox of sonic exe and it only does damage when I touch him but he doesn’t chase.. what do I do. Was it bc I didn’t do the same rig as you or no..? I just really need to figure it out. Please and thank you🙏

[@devmelonroblox]

Do you get any errors in your script?

[@TTVtreekoVr]

@@devmelonrobloxno, but does it matter that I didn’t animate it and only copy and pasted the animate script?

[@zevkellygaintano3176]

You're fr one of the best Roblox Devs on RUclips right now.

[@devmelonroblox]

Thanks!

[@deathreaper4200]

thank you so much

[@Mr.Outlet1]

I tried to do the chase script and after i was done it didnt work i do think it had something to do line 37 where you had “if Closest and (HumanoidRootPart.Position - Closest.Position).Magnitude

[@HatInInternet]

U have output windows opened? If you're not getting any errors, try putting print("test") in your script and see if it prints it.

[@kadsian539]

what about adding an animation to it with cooldowns

[@MasterGamer_122YT]

How would i make it immortal or something like that bc if i put 2 they kill eachother

[@BushiX5]

Thanks❤ and how do you replace the animations with different ones?

[@devmelonroblox]

Yopu check the naimation script and there will be the run id in there youll find it

[@ERICNETIC_pubgm]

How do you make it so that multiple npcs dont kill each other but kill you only

[@devmelonroblox]

You can name them all one name and where it checks for humanoid you can do if name ~= “name of npc”

[@EricChawira]

@@devmelonrobloxcan u explain in more detail

[@StupidMiners]

I have a small question. I made a bunch of enemies but i don't want them to attack each other. However I don't really know how to fix that so could you make a video on how to make that?

[@DaLemonMonke158]

Hey thanks for helping me with my game!
(your prob not going to see this) but how can i make it so the rig will chase after a player when its near them?
thanks for helping me with my game and i hope you have the time to respond

[@devmelonroblox]

Hey! I think I. Will make a renewed version of the tutorial but there’s a way of checking the distance between the player and the dummy and checking if it’s lower

[@devmelonroblox]

It’s quite hard to explain in comments

[@DaLemonMonke158]

Oh wow you actually did respond! That’s fine though I will try my best!

[@devmelonroblox]

@@DaLemonMonke158 ofc! Good luck with ur game

[@KingLlama432]

i made my own custom modle but it wont move it only follows my direction

[@digipug]

Finally a script that works
I have looked trough so many tutorials and they have just been filled with people that cant speak properly and they also dont teach you anything they just say copy this script that I have linked in the description.

[@Akino_Artist]

finaly someone explaining the script not just giving it to us to copy it thanksss

[@devmelonroblox]

Thansk!

[@Igrowtreesforlife]

Someone help me it’s not working and the output says there are no errors

[@BlueWithaFruit]

How would i be able to change the max distance, like if you were in a certain range it would follow you

[@devmelonroblox]

You set the max distance on the script

[@Rushing-know]

@@devmelonroblox could i do local maxDistance = 10 ?

[@TheGuyThatKnewThe]

NO WAY! This is amazing. YOU literally read my mind. I was looking for the perfect video, and i think i found it! Thanks so much!

[@devmelonroblox]

You're so welcome!

[@thecubeheadguy6747]

my npc just teleports at me for some reason. I even set its walkspeed to 10

Hey. idk if ur gonna see this but how do I make a custom model of the AI

Hey devmelon! I watched your tutorial on how to make a difficult chart obby and it really helped! How did you learn code? I want to learn lua too but I cant learn it. Its too hard.

[@devmelonroblox]

I think I learned by watching dev kings beginner tutorials

[@autorade69420]

how do i make them respawn?

[@SafeOfArsenal]

is it possible to make a safe zone where the npc wont go inside of?

[@BushiX5]

I made multiple and the enemy NPCs hurt eachother pls help

[@The_ShyGuy64]

It works well unless more than 1 npc is near eachother, then they will kill eachother

[@devmelonroblox]

You can add a code so that it doesn’t follow if the persons name is npc and name all the npcs npc
