Changed event only firing once

Help and Feedback Scripting Support

I’m trying to make a ServerSided AntiCheat, but there is one problem, the Changed event is only firing once, and that’s only when my Character spawns. Couldn’t find anybody else having the same problem.

It only prints “HumanoidRootPart Position Changed” once.

Code 
local Character = script.Parent

if Character then
	print("Character Added")
end

local HumanoidRootPart = Character:WaitForChild("HumanoidRootPart")
print("HumanoidRootPart Found")

HumanoidRootPart.Changed:Connect(function(Property)
	if Property == "Position" then
		print("HumanoidRootPart Position Changed")
	end
end)

Yes I’ve tried GetPropertyChangedSignal, does the same thing.

Honestly, Changed has a history of being pretty inconsistent for me. I’ve run into this same exact issue when trying to make an anti-cheat for speed hacking.

My solution was to store everyone’s current positions and check for updates constantly through a loop.

local Players = game:GetService("Players")
local playerPosition = {} -- Dictionary

Players.PlayerAdded:Connect(function(player)
    while player ~= nil do
        local character = player.Character
        if not character then
            character = player.CharacterAdded:wait()
        end
        if playerPosition[player.Name] == nil then
            playerPosition[player.Name] = character.HumanoidRootPart.Position
        else
            if character.HumanoidRootPart.Position ~= playerPosition[player.Name] then
                playerPosition[player.Name] = character.HumanoidRootPart.Position
                print("Position for " .. player.Name .. " changed!")
            end
        end
        wait()
    end
    playerPosition[player.Name] = nil -- remove upon leaving
end)
