Players distance from npc

Hi,

I am trying to code a way to find out when a player is within a certain distance to a moving NPC so I can do something, I am also trying to show the distance on the NPC visibly by having a circle on the floor around the NPN…

thanks

You’d have to use .RenderStepped or another render event to do this, as well as the .Magnitude property of Vector3s.

local runService = game:GetService('RunService')
local players = game:GetService('Players')

local localPlayer = players.LocalPlayer
local character = localPlayer.Character or localPlayer.CharacterAdded:Wait()
local humanoidRootPart = character:WaitForChild('HumanoidRootPart')

local destinationNPC = workspace.NPC
local maxRadius = 10

runService.RenderStepped:Connect(function()
    local npcPosition = destinationNPC.HumanoidRootPart.Position
    local magnitude = (humanoidRootPart.Position - destPosition).Magnitude
    if magnitude <= 10 then -- if the distance is 10 or less then
        print(localPlayer, 'is', magnitude, 'studs away from the NPC!')
    end
end)
