How to check if a player is close to a model

Hello i was wondering how you could check if a player is some studs away from a model as i want to make it so that a certain script disables after the player walks a certain amount of studs away from that model?

You’d want to use magnitude:

(player.HumanoidRootPart.Position - model.PrimaryPart.Position).magnitude

That’ll give you a number back, if it’s under some amount you could say they’re close to it; otherwise they’re not. Then I’d have that in some kind of check - either a loop, an event connection, etc., but some way that you can check

You can use magnitude to see the distance between 2 things.

To use the magnitude, you must first have access to part of the player, and access to a part in the model. The formula to get the magnitude looks like this: local mag = (torso.Position - modelPart.Position).magnitude.

Hope this helps!

As stated by the others, you could use the magnitude to determine the distance between two objects. If you prefer to use it multiple times, a function would help.

local function GetDistance(p1,p2)
    local Distance = (p1.Position - p2.Position).magnitude
    return Distance
end

The function can be run from any instance with a recorded position.

Well once i have a specified distance away how do i use that in a script, i am sorry but what i am getting here is confusing as i am not the best scripter and i have never worked with this.

@FIREYAUTO’s GetDistance function returns the distance between two objects. Pass in your model’s PrimaryPart as the first parameter, and the player’s HumanoidRootPart as the second parameter and you get the distance between the player and your model. You should put the code inside a LocalScript and use a while loop to continuously check the distance between the player and your model.

First, you should place an invisible part in the center of your model and set it as the PrimaryPart of your model (or if you already have a part in the center of the model, use it). Create a LocalScript inside game.StarterPlayer.StarterCharacterScripts and paste the following code in:

local humanoidRootPart = game.Players.LocalPlayer.HumanoidRootPart
local modelPrimaryPart = yourModel.PrimaryPart

local function GetDistance(p1,p2)
    local Distance = (p1.Position - p2.Position).magnitude
    return Distance
end

while true do
    -- if player is 10 studs away from model
    if GetDistance(modelPrimaryPart, humanoidRootPart) > 10 then
        -- stop your script here
    end
end

local player = game.Players.LocalPlayer
local MAX_RANGE = 15 --change here

while player:DistanceFromCharacter(workspace.YourModel.Head.Position) < MAX_RANGE do
   print("ScriptEnabled = false")
   ChoseYourScript.Disabled = true
else
   print("ScriptEnabled = true")
   ChoseYourScript.Disabled = false
end

Do you know how someone would go about this in a server script?

#10

havent tried this. This should work.

local rs = game:GetService("RunService")

rs.RenderStepped:Connect(function()
	for i,v in pairs(workspace:GetDescendants()) do
		if v:FindFirstChildOfClass("Humanoid") then
			local human = v:FindFirstChildOfClass("Humanoid")
			local hrp = human.Parent:FindFirstChild("HumanoidRootPart")

			if hrp then
				if (hrp.Position - script.Parent.Position).Magnitude < 5 then
					print("close")
				end
			end
		end
	end
end)

Man, run service don’t work on server scripts.

#12

it does… just use heartbeat instead of renderstepped

your addition was greatly needed to a year old post

#15

Since the topic has already been bumped I might as well respond: Run service does work on server scripts, just not renderstepped

oh, i didn’t know that lol brah limit word :frowning:

thx, i just literally revived the post man lol
