Magnitude not working?


I’ve been working with magnitude recently to make a Leap Of Faith affect from Assassin Creed, so when I started writing the script I had to check the Z and the Y axis between the player and the hay stacks to make sure the player is above the hay stacks on a high spot, but this is when I ran into this problem magnitude is not working with 1 Axis nor all axis and I’m confused to why this is happening, any help is appreciated.

Hay stacks folder:



local UIS = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()

repeat wait() until character:FindFirstChild("Humanoid")

local Count = 0

-- Checking if the player is running, crouching, etc
local function CheckBehavior()
	local folder = character.Behavior
	for i, v in ipairs(folder:GetChildren()) do
		if v:IsA("BoolValue") then
			if v.Value == false then
				Count += 1

-- Loading Animations
local LoFS = character.Humanoid:LoadAnimation(script.LoFStart)
local LoFM = character.Humanoid:LoadAnimation(script.LoFMid)
local LoFF = character.Humanoid:LoadAnimation(script.LoFFinish)

UIS.InputBegan:Connect(function(inpt, UPE)
	if UPE then return end
	if inpt.KeyCode == Enum.KeyCode.F then
		if Count == 4 then
			Count = 0
			-- Looping through the hays and comparing positions
			for i, v in ipairs(game.Workspace.Hays:GetChildren()) do
				-- Getting the magnitude between the player and the hay stack
				local UpMag = (player.Character.HumanoidRootPart.Position.Y - v.Position.Y)
				local DisMag = (player.Character.HumanoidRootPart.Position.Z - v.Position.Z)
				print(DisMag, " Non magnitude")
				print(DisMag.magnitude, " with magnitude") -- Error here
				print(UpMag.magnitude) -- Error here
				if DisMag.magnitude <= 30 and UpMag.magnitude >= 20 then
					local Root = player.Character.HumanoidRootPart
					local Info =,Enum.EasingStyle.Quint,Enum.EasingDirection.Out)
					character.Humanoid.Jump = true
					-- Pulling the player to the hay stack
					game:GetService("TweenService"):Create(Root, Info, {Position = v.Position}):Play()


You can only use magnitude on Vector3 Values. Since you’re getting only a part of the Vector3 values when indexing UpMag and DisMag, it’s just a number, hence attempt to index number with magnitude.

local StartPoint =,0,0)
local EndPoint =,100,100)

local Magnitude = (EndPoint - StartPoint).magnitude

player.Character.HumanoidRootPart.Position.Y - v.Position.Y
The Y values are plain numbers and what this returns is also a plain number.
There’s no magnitude of a number. If you’re trying to get the absolute value instead (disregarding negativity), you can use math.abs(num).

How will i interpret math.abs() in my script

math.abs(UpMag) returns UpMag if it’s positive and -UpMag if it’s negative, i.e. the returned value is always positive.

Yes but that will get the absolute number of all axis combined wouldn’t it?

You’re extracting single axes by indexing the vectors with Y and Z. Plain numbers don’t have any further properties / behaviour defined, they’re raw byte data so to say.

So in this case I’ll do this right?

local upmag = (math.abs(rootpart.Position.Y) - math.abs(v.Position.Y))

and it’ll be like magnitude but without using magnitude
