Use the :GetFriendsAsync() method found in the Players service:

local success, friensPages = pcall(game.Players:GetFriendsAsync(your_UserId))
-- always wrap asynchronous calls in a pcall since they tend to fail
-- (which will terminate your thread execution (aka stop code))

This method will return a FriendsPages object, which contains a player’s friends, their UserIds, Usernames and Online status. They’re not tables, but rather Instances, so you can convert it into a table:

-- Code stolen from docs lol
local function iterPageItems(pages)
	return coroutine.wrap(function()
		local pagenum = 1
		while true do
			for _, item in ipairs(pages:GetCurrentPage()) do
				coroutine.yield(item, pagenum)
			end
			if pages.IsFinished then
				break
			end
			pages:AdvanceToNextPageAsync()
			pagenum += 1
		end
	end)
end

local success, friendPages = pcall(game.Players:GetFriendsAsync(your_UserId))
local userIds = {}
for item, _pageNo in iterPageItems(friendPages) do
	table.insert(userIds, item.Id)
end

You can then get a HumanoidDescription for a random UserId:

local randomFriend = userIds[math.random(1, #userIds)]
local HumanoidDescription = Players:GetHumanoidDescriptionFromUserId(randomFriend)

And finally apply this HumanoidDescription to a rig (NPC):

local Rig = workspace.Rig -- get your rig
Rig.Humanoid:ApplyDescription(HumanoidDescription)

Or you can directly create a model from the UserId:

Players:CreateHumanoidModelFromUserId(randomFriend)

for item, _pageNo in iterPageItems(friendPages) do
it say attempt to call missing method ‘GetCurrentPage’ of string

My bad, called pcall the wrong way. Should be fixed here:

local Players = game:GetService("Players")

local success, friendPages = pcall(function()
	return Players:GetFriendsAsync(UserIdHere)
end)

if not success then
    -- remember to handle pcall errors
end

local function iterPageItems(pages)
	return coroutine.wrap(function()
		local pagenum = 1
		while true do
			for _, item in ipairs(pages:GetCurrentPage()) do
				coroutine.yield(item, pagenum)
			end
			if pages.IsFinished then
				break
			end
			pages:AdvanceToNextPageAsync()
			pagenum += 1
		end
	end)
end

local userIds = {}
for item, _pageNo in iterPageItems(friendPages) do
	table.insert(userIds, item.Id)
end

local randomFriend = userIds[math.random(1, #userIds)]
local HumanoidDescription = Players:GetHumanoidDescriptionFromUserId(randomFriend)

local Rig = workspace.Rig -- replace with your rig
Rig.Humanoid:ApplyDescription(HumanoidDescription)

How to Set Friends Appearance to a npc model
#5

it works but is there a way to do humanoid:ApplyDescription with local script?

#6

Of course. Put that code in a LocalScript.

#7

and it say humanoid:ApplyDescription can only be called by the backend server

I was typing a code when I saw your question, but I had to go afk, @Vanniris code is fine, works as intended. But it wont work client sided if you dont create the Rig from a client script, otherwise it will say you cannot change the Description

Yup, thats because the rig exist in server side since the beginning, and a client cant edit a serversided description, the rig should be created from client side to edit that

Just instead of this:

local HumanoidDescription = Players:GetHumanoidDescriptionFromUserId(randomFriend)
local Rig = workspace:WaitForChild("Rig") -- replace with your rig
Rig.Humanoid:ApplyDescription(HumanoidDescription)

Use this:

local newFriend = Players:CreateHumanoidModelFromUserId(randomFriend)
newFriend.Parent = game.Workspace

@Vanniris already suggested to use CreateHumanoidModelFromUserId() instead of editing an existing Rig in workspace
