Can`t read WalkSpeed / JumpPower?

Helllo, i wrote this code for Anti-Hacking! if i change WalkSpeed / JumpPower it doesnt kick me?? can someone please help?! i can try to print the WalkSpeed / JumpPower but its always the same, even if i change it!? i have to change the walkspeed sometimes so i made a Changing BoolValue so i can set Changing to true then change the walkspeed in the script.Configuration then wait until walkspeed was changed in humanoid then set Changing to false

Put this code into StarterCharacterScripts:

-- Settings --
kickIfFellOut = true

kickFromWalkSpeed = true
maxWalkSpeed = 20

kickFromJumpPower = true
maxJumpPower = 50
--------------
local config = Instance.new("Configuration", script)
local changing = Instance.new("BoolValue", config)
changing.Name = "Changing"
local walkspeed = Instance.new("IntValue", config)
walkspeed.Name = "WalkSpeed"
walkspeed.Value = 16
local jumppower = Instance.new("IntValue", config)
jumppower.Name = "JumpPower"
jumppower.Value = 50

local fpdh = workspace.FallenPartsDestroyHeight
local plr = game.Players:FindFirstChild(script.Parent.Name)

while true do wait()
	local hum = script.Parent:FindFirstChild("Humanoid")
	if hum then
		if kickFromWalkSpeed then
			if config.WalkSpeed.Value > maxWalkSpeed then
				plr:Kick("WalkSpeed Cheat")
			end
		end
		if (not config.Changing.Value) and (not config.WalkSpeed.Value == hum.WalkSpeed) then
			plr:Kick("JumpPower Cheat")
		end
		if config.Changing.Value then
			hum.WalkSpeed = config.WalkSpeed.Value
			wait()
			if config.Changing.Value then
				wait()
			end
			if config.Changing.Value then
				plr:Kick("WalkSpeed Cheat")
			end
		end
		
		
		if kickFromJumpPower then
			if config.JumpPower.Value > maxJumpPower then
				plr:Kick("JumpPower Cheat")
			end
		end
		if (not config.Changing.Value) and (not config.JumpPower.Value == hum.JumpPower) then
			plr:Kick("JumpPower Cheat")
		end
		if config.Changing.Value then
			hum.JumpPower = config.JumpPower.Value
			wait()
			if config.Changing.Value then
				wait()
			end
			if config.Changing.Value then
				plr:Kick("JumpPower Cheat")
			end
		end
	end
	
	
	if kickIfFellOut then
		local hrp = plr.Character:FindFirstChild("HumanoidRootPart")
		if hrp then
			local pos = hrp.Position
			if pos.Y < fpdh+100 then
				plr:Kick("Fell out of world")
			end
		end
	end
end

I see you are comparing the values in config, but do you actually set them to reflect the walkspeed/jumppower of the humanoid? If not, they aren't going to just automatically change by themselves.

What you should do instead is check the properties of Humanoid on the Changed event

hum.Changed:Connect(function(prop)
	if prop == "WalkSpeed" or prop == "JumpPower" then
		--check
	en
end)

Btw, you should NEVER kick the player from a LocalScript. You should always do it from a server script, because if you do it locally, it can be bypassed by exploiters very very easily.

(And so they can override Humanoid.WalkSpeed or Humanoid.JumpPower to return fake values, therefor bypassing your anti cheat completly)
