How to detect how far away the npc is from the player?

Hello, I’m working on a game based off the backrooms And I thought of an idea that I could add a “how far away is the NPC from you: whatever stud” but little did I know, I’m completely clueless on how to do it.

I looked around Devfourm to see if there were any posts about this and I tried doing this

local playerRoot = game.Players.LocalPlayer.Character:WaitForChild("HumanoidRootPart")
local modelRoot = game:GetService("Workspace").killingEnity.HumanoidRootPart
local distance = (playerRoot.Position - modelRoot.Position).Magnitude 


local radius = 50

if (distance <= radius) then
	script.Parent.Label.Text = "You might wanna run.."
else
	script.Parent.Label.Text = "Entity is not near you."
end

It does not work nor error.
Any help?

Detect the NCP’s CFrame then compare it to the player’s CFrame! :yum:

Doesn’t the players CFrame change every time you move?

Yes it is ! :grinning:
It is not what you want ? :thinking:

Since the code is not checking the distance continuously it only prints out once,
So to do that you’ll need to put the code in a loop like so

while wait() do
if (distance <= radius) then
   script.Parent.Label.Text = "You might wanna run.."
else
   script.Parent.Label.Text = "Entity is not near you."
end
end

Hope it helped.

Weird, doesn’t function at all Aswell? i used print to see if it does work but it only prints the “it is not near you” one Not the “It is near you, run” one.

Maybe you miscalculated the distance between the player and the entity ?

10 
local distance = (playerRoot.Position - modelRoot.Position).Magnitude
11

You’ll actually need to update this variable whenever the player resets/dies,
which might be why its not working

12

Maybe try to print the distance to see if you’ve got the right calculation ?

I’ve got it you made a mistakes at the line 2 it not killingEnity but killingEntity ! :grinning:

Here, fixed it for you.

local playerRoot = game.Players.LocalPlayer.Character:WaitForChild("HumanoidRootPart")
game.Players.LocalPlayer.CharacterAdded:Connect(function(char)
    playerRoot = char:WaitForChild("HumanoidRootPart")
end)
local modelRoot = game:GetService("Workspace").killingEnity.HumanoidRootPart
local radius = 50


while wait() do
local distance = (playerRoot.Position - modelRoot.Position).Magnitude 
if (distance <= radius) then
	script.Parent.Label.Text = "You might wanna run.."
else
	script.Parent.Label.Text = "Entity is not near you."
end
end
