I want that the door works with localscript but it doesn't how i can do that?

while wait(0.001) do
local required_points = 100000

local db = true
script.Parent.Touched:connect(function(hit)
	local player = hit.Parent
	if hit.Parent:FindFirstChild("Humanoid")then
		local player = game.Players:GetPlayerFromCharacter(hit.Parent)
		if player.leaderstats.Coins.Value >= required_points then
			if db then
				db = false
				script.Parent.Transparency = 0.5
				script.Parent.CanCollide = false
			end
		else
		print("you haven't enough money")
		end
	end
end)
end

idk why it is not working it is working in a normal script but the problem is that a other players can go threw when a player with 100K touches the door

First off remove the while loop. It is not needed. And please don't call wait with such a small number, at least call it with 1/10. And do not use that call as condition of while loop as you don't know how it works. Don't follow conventions just for being popular, follow them because you know how they work.

It lets other people through because you never set CanCollide back to true. If you want you can teleport a player through the brick.

local REQUIRED_POINTS = 100000
local db = true
local door = script.Parent
local Players = game:GetService("Players")

door.Touched:Connect(function(part) -- :connect is deprecated in favour of :Connect
    local player = Players:GetPlayerFromCharacter(part.Parent)

    if player and player.leaderstats.Coins.Value >= REQUIRED_POINTS then
        if db then
            db = false
            door.Transparency = 0.5
            player.Character:SetPrimaryPartCFrame(door.CFrame*CFrame.new(0, 0, -10))
            wait(2)
            door.Transparency = 0
        else
            print("you haven't enough money")
        end
    end
end)

This should teleport them 10 studs forward. Or you could quickly set it back to false but what if a player is behind them.
