How do I position npcs inside of a part?

Help and Feedback Scripting Support
#1

So in the game i’m making I want to spawn npcs around a red part that is the size of where they should spawn randomly.

How can I do this?

How are you spawning the NPCs now? There is probably a location or Part used in the script you are using that you can change the value of to make them spawn in a more random area around that spot.
Look up: https://developer.roblox.com/en-us/api-reference/datatype/Random

local npcTemplate = game:GetService('ReplicatedStorage'):WaitForChild('Builderman')
local spawnPart = script.Parent


local random = Random.new()

function getRandomLocationInsidePart(part)
	-- Returns the part's CFrame plus or minus half of the part's size
	return part.CFrame * CFrame.new(
		part.Size * Vector3.new(random:NextNumber(-.5,.5), random:NextNumber(-.5,.5), random:NextNumber(-.5,.5))
	)
end

function spawnNPC()
	-- Get a random cframe, and use just the position as the spawn point
	local randomLocation = getRandomLocationInsidePart(spawnPart).p
	-- Get a random rotation so that the npc isn't always facing the same direction
	local randomRotation = CFrame.Angles(0,math.pi*random:NextNumber(0,2),0)

	local npc = npcTemplate:clone()
	local hipHeight = npc.Humanoid.HipHeight
	-- Position the NPC at the random location but a little higher because they are standing.
	npc.HumanoidRootPart.CFrame = CFrame.new(randomLocation + Vector3.new(0,1+hipHeight,0)) * randomRotation
	npc.Parent = workspace
	return npc
end


-- Spawn an NPC every 5 seconds, but also remove the old one.
local existingNPC = nil
while true do
	if existingNPC then
		existingNPC:Destroy()
	end
	existingNPC = spawnNPC()
	wait(5)
end
