How do I make a BillboardGUI dissapear at a certain range?

Hi. I want a BillboardGUI to be visible when you're close to it, but disappear when you get too far away.

I tried this script, but it doesnt seem to work.

local distance = (game.Players.LocalPlayer.Character.HumanoidRootPart.Position - script.Parent.Parent.Parent.Position).magnitude
while true do wait()
	if distance < 10 then
		print("visible")
	else
		print("not visible")
	end
end

Might not be the most efficient way to do this, but I thought I'd share this anyway

You can make a hitbox for the part, so when the player touches the hitbox, the Gui will be enabled

local hitbox = *part here*
local gui = *billboardgui here*
local debounce = true

hitbox.Touched:Connect(function(hit)
	if hit.Name == "HumanoidRootPart" and debounce then
		gui.Enabled = true
		debounce = false
end
end)

hitbox.TouchEnded:Connect(function(x)
	if x.Name == "HumanoidRootPart" and not debounce then
		gui.Enabled = false
		debounce = true
	end
end)

LocalScript btw

There is a property of the BillboardGUI called "MaxDistance" and it is exactly what you're looking for and measured in studs.
