If statement doesnt work in repeat until loop

HI there!
I’m Glade and I’m having a problem with my repeat loop. I have an if statement in my repeat loop but it doesn’t work.

repeat
	spPath:Run(target.HumanoidRootPart.Position)
	NPC:SetAttribute("Chasing", true)
	curTarget = target
				
	if Magnitude < 3 then
		jumpscare(target)
	end			
until target.Humanoid.Health < 1 or Magnitude > leaveDistance or NPC.Humanoid.Health < 1

I don’t see anything syntactically wrong on first glance.

How are you defining Magnitude?

The first step to debugging (ideally before you ask for help) is to check what the variables are. The if statement isn’t working. if statements always work, but what’s inside might not.

First, check if we’re making it past the if check. print(Magnitude) before that line and print(“Passed!”) after that line. If it makes it through, figure out why the function isn’t running properly.

If it didn’t, what did Magnitude print? More than 3? You’ll need to figure out why. There’s a possibility that Magnitude isn’t being calculated correctly, and there’s a chance that it just isn’t being updated. The most likely of these two options, given what I can see, is that it isn’t being updated.

If you did this earlier in the script: Magnitude = (a-b).Magnitude, then it copied this number into the Magnitude variable and then it won’t update the variable any more. Programming works differently from math. In math, two things that are equal will always be equal. In programming, the = operator only assigns a value to a variable. I apologize if you already know this.

dist = 5
Magnitude = dist
print(Magnitude) --> 5
dist = 10
print(Magnitude) --> 5
dist = 2
print(Magnitude) --> 2

Here you can see that even though we set Magnitude to equal dist, it won’t keep up with dist. If this is your problem, you need to move the Magnitude calculation into your loop so that it gets updated.

If that’s not your problem, then let’s take a look at how you’re calculating Magnitude.

If the if statement is succeeding but still nothing happens, we’ll need to take a look at jumpscare function.

Well if you don’t understand your IF statement you need to know what magnitude is:
Magnitude in roblox uses vector theory.
That essentially means:
Square Root of (x^2 + y^2 + z^2)
Magnitude works off of both Position and Size

yes

Also I’m having problem with my raycast function.

function canSee(tar)
	local ori = RootPart.Position
	local dir = (RootPart.Position - tar.HumanoidRootPart.Position).Unit * maxDistance
	local ray = Ray.new(ori, dir)
	local hit, pos = workspace:FindPartOnRayWithIgnoreList(ray, {script.Parent})
	local status = false
	

	if hit then
		if hit:IsDescendantOf(tar) then
			local unit = (RootPart.Position - tar.HumanoidRootPart.Position).Unit
			local lv = RootPart.CFrame.LookVector
			local dot = unit:Dot(lv)
			
			if dot > 0 then
				status = true
			end
		else
			status = false
		end
	end
	
	return status
end

function chaseTarget(target)
	local path = PathfindingService:CreatePath(Params)
	path:ComputeAsync(RootPart.Position , target.HumanoidRootPart.Position)
	local waypoints = path:GetWaypoints()
	if target and target.Parent and canSee(target) then
		print("Chasing")
		if target.Humanoid.Health > 0 and target and Players:FindFirstChild(target.Name) then
			
			repeat
				spPath:Run(target.HumanoidRootPart.Position)
				NPC:SetAttribute("Chasing", true)
				curTarget = target
				local Magnitude = (RootPart.Position - target.HumanoidRootPart.Position).magnitude
				
				if Magnitude < 3 then
					jumpscare(target)
				end
				
			until target.Humanoid.Health < 1 or Magnitude > leaveDistance or NPC.Humanoid.Health < 1
			
			print("Stopped Chasing")
			if spPath and spPath._moveConnection then
				spPath:Stop()
			end
			NPC:SetAttribute("Chasing", false)
			curTarget = nil
		end
	end
end ```
