How do I make the random appearance system for NPCs?

Help and Feedback Scripting Support

  1. What do you want to achieve?
    So, basically, I want to make the random appearance system for NPCs, and, make sure all accessories are certain. Like, what I meant is, everytime you make a new NPC, it will pick some random accessories, such as hair, hat, glasses, masks and more for them to wear. (Depends on their gender.)

  2. What is the issue?
    I tried to make the one myself, but, I feel so lost, because, I’m not sure what I’m doing with it, and, I’ve had a few problems with it. Any advices would be appreciated.

  3. What solutions have you tried so far?
    I’ve tried to look everywhere, and, unfortunately, there doesn’t seem to be such a thing like that. So, I’m hoping anyone here knows how to do this.

Even if I should just make a bunch of NPCs with the different appearance in the folder, for me personally, I’d prefer not to do that, for some reasons. :frowning_face:

just have each accessory you wish to put on npcs in an ordered list of folders

accessories
hats
glasses
etc

then doing simple random math you could pick a random accessory from each folder

local random = Random.new()
local hats = location of hats folder:GetChildren()

local r = random:NextInteger(1, #hats)
local hat = hats[r]

then have a template npc and call Humanoid:AddAccessory on that template

Yeah, that’s what I’m basically doing, but, the thing is, is there a way to prevent NPC from wearing the wrong accessories or something like this?

Like, for example, let’s just say, if you want to make a soldier with beret only or whatever, but, they have another accessories in the same order, when that’s not supposed to happen.

Or, if you just want to make a woman, but, she has a facial hair that only men wears. Is there any way to prevent that happening?

Then, adding on to his script, you would have to have a separate folder for the genders and maybe an attribute in the NPCModel that gets set in a randomizer (Like maybe 1 == boy and 2 == girl, or just as strings).

-- Just an example ServerScript, located in the model of the NPC.

local ReplicationStorage = game:GetService("ReplicationStorage")
local AccessoriesFolder = ReplicationStorage:WaitForChild("Accessories")
local SetAccessoryFolder -- we'll set this later, for now it's nil.

local NPC = script.Parent -- assuming the scripts parented to the NPC.
NPC:SetAttribute("Gender", math.random(1, 2)) -- setting the gender via number.
local Humanoid = NPC.Humanoid
local Gender = NPC:GetAttribute("Gender") -- it'll return as a number.
-- using attributes, it allows other scripts to get or modify this data.
-- if you're not planning to use this universally through other scripts,
-- you can just do:
-- local Gender = math.random(1, 2)
local howManyHats = math.random(1, 3) -- just randomizing the amount of
-- hats the NPC can be able to wear.

if Gender == 1 then
     SetAccessoryFolder = AccessoriesFolder.Woman 
     -- assuming it's a folder parented to the AccessoriesFolder
else
     SetAccessoryFolder = AccessoriesFolder.Man 
     -- assuming it's a folder parented to the AccessoriesFolder
end

local AccessoryTable = SetAccessoryFolder:GetChildren()
local obtainableHats = #AccessoryTable -- how many hats that is useable

for count = 1, howManyHats do -- a for loop to acquire hats. 
     local newHat = AccessoryTable[math.random(1, obtainableHats)]:Clone()
     newHat.Parent = NPC -- assuming it's class is an Accessory or Hat.
     -- alternatively, you could just do this:
     -- local newHat = AccessoryTable[math.random(1, obtainableHats)]
     -- Humanoid:AddAccessory(newHat)
end

Okay, I’ll try it out and see if It works. Also, is it possible to add the whitelist and blacklist on it? Like, I meant, I don’t want a NPC to wear the beret and raised goggles at the same time, or, a civilian with the floating helmet addons. That’s what worries me the most.

Yes! You could then modify the NPC to have a randomized attribute/value that expressed what type of NPC it is and what it should wear.

Here’s the new code with what you wanted:

-- Just an example ServerScript, located in the model of the NPC.

local ReplicationStorage = game:GetService("ReplicationStorage")
local AccessoriesFolder = ReplicationStorage:WaitForChild("Accessories")
local SetAccessoryFolder -- we'll set this later, for now it's nil.

local NPCType = {
     "Civilian",
     "Military",
     "Officer" -- you can add as many as you'd like.
}

local NPC = script.Parent -- assuming the scripts parented to the NPC.
NPC:SetAttribute("Gender", math.random(1, 2)) -- setting the gender via number.

local Humanoid = NPC.Humanoid
local Gender = NPC:GetAttribute("Gender") -- it'll return as a number.
-- using attributes, it allows other scripts to get or modify this data.

-- if you're not planning to use this universally through other scripts,
-- you can just do:
-- local Gender = math.random(1, 2)

local howManyHats = math.random(1, 3) -- just randomizing the amount of
-- hats the NPC can be able to wear.

if Gender == 1 then
     SetAccessoryFolder = AccessoriesFolder.Woman 
else
     SetAccessoryFolder = AccessoriesFolder.Man 
end

-- local AccessoryTable = SetAccessoryFolder:GetChildren()
-- local obtainableHats = #AccessoryTable -- how many hats that is useable
-- we won't be needing those now...

-- instead, we'll use this:
local TypeOfNPC = NPCType[math.random(1, #NPCType)]

for count = 1, howManyHats do -- a for loop to acquire hats. 
     local HatsFor -- this is to express the type of hats the NPC can wear.

     for _, class in ipairs(NPCType) do -- making it easier with a for loop.
          if TypeOfNPC:lower() == class:lower() then -- this allows it to NOT
               -- be case sensitive.

               HatsFor = SetAccessoryFolder[class] -- assuming the class
               -- is a folder parented to the AccessoryFolder.
          end
     end

     local newHat = HatsFor[math.random(1, #HatsFor)]:Clone()
     newHat.Parent = NPC -- assuming it's an accessory
end

Is there any ways to do it on all accessories though? Without checking the type of NPC.

I’m sorry if I’m asking more. :sweat_smile:

#8

Yeah by using tables. [][][][][][][]

You could have the accessories have the same Attribute that changes the type of hat it is. But it would cause not only a headache, but also it wouldn’t be good randomizing. So, having the accessories in a folder with the class name would be better and not as difficult.

I could be wrong though.

#10

ORR, you can change these codes to have it be set without randomizing:

local TypeOfNPC = "Civilian" -- whatever ur class's name is.

MY BAD I READ UR QUESTION WRONGGG

#11

I mean, that’d be too much work, especially if you have too many accessories here, but, I guess, I’ll give it a try. If not working, I’ll try to figure it out. :smiley:

#12

You can do something like this, I mean I think this would work.

local NPCTables = { 
1 = "NPC1",
2 = "NPC2",
3 = "NPC3"
}

print(math.random(1,#NPCTables))
#13

I’d say it’d be more efficient, more if you put it in a module.

Hm, alright, I’ll give it a try. Hopefully this will work perfectly fine without any problems, that’d be so annoying.

#15

By the way, thanks to everyone who is helping me, I appreciate all of your advices. :smiley:

#16

Should I make a new module just for that?

#17

Yeah sure to be more organized.

#18

Do you have any advices for whitelist and blacklist detection system? I’m kind of stuck on that part.

#19

Yeah you can do something like this. Also to make it better, use UserID instead of names.

local WL = {"KultDeeri"}
local BL = {"Player1"}

if table.find(WL, plr.Name) then
--whitelisted
elseif table.find(BL, plr.Name) then
--blacklisted
return
end
end

The problem is that, I want to use the Dictionaries for each accessories with whitelist and blacklist in it, but, It couldn’t find any one, and, I don’t know what I’m doing wrong.
