Need help with a script

[dert_7 (dert)]

I need help, I tried to ask the assisant to code a script for my NPC where if its in about 50 stud proximity to the player it moves 150 studs away, but when I played the game the NPC stood still in place, I dont know if I need to make some remotes or something, because I just threw the script right in.

-- Script for making the model attempt to stay 150 studs away from the player

local model = script.Parent
local player = game.Players.LocalPlayer

local function distance(point1, point2)
    return (point1 - point2).Magnitude
end

while true do
    local playerPosition = player.Character.HumanoidRootPart.Position
    local modelPosition = model:GetModelCFrame().Position
    local currentDistance = distance(playerPosition, modelPosition)
    local targetDistance = 150
    local direction = (playerPosition - modelPosition).unit
    local moveVector = direction * (currentDistance - targetDistance)
    model:SetPrimaryPartCFrame(CFrame.new(modelPosition + moveVector))
    wait(0.1)
end

Try looking up and using the MoveTo() function, it might be what you are looking for.
