How to make a simple custom admin system

Hello fellow developers! I was once trying to make a custom admin system. But, I never knew how to start/make it. If you are trying to make a custom admin system, hopefully this tutorial will help you and not make you stuck in the position I was in.

Step 1
Setup
First, make a script in ServerScriptService. Name it however you’d like. I am going to name it Admin.

Step 2
Essentials
I am going to place the important variables we need at the top of our script.

local Players = game:GetService('Players');
local Prefix = ':'; -- What goes in front of every command that is ran
local Admins = {};

The admins table will be used to place the username or userID of those who are allowed to run the commands.

Step 3
Scripting
Now comes the fun part! The actual scripting. Make sure to follow exactly how I have it.

First, we are going to create a function that makes sure the person that runs the command is an admin.

function CheckIfAdmin(plr)
	for i = 1, #Admins do
		if Admins[i] == plr.UserId or Admins[i] == plr.Name then
			return true;
		end
	end
	
	return false;
end

Now, we are going to make the command handler.

Players.PlayerAdded:Connect(function(p)
	p.Chatted:Connect(function(m)
		local args = string.split(m, ' ');
		
		if string.lower(args[1]) == Prefix..'test' then
			if CheckIfAdmin(p) == true then
				print('Works!');
			end
		end
	end)
end)
  • string.split() makes the command into an table like this {’:test’, ‘e’}.
  • string.lower() makes the first argument lowercase to check if it’s a command so it can check if it’s like ‘:tEsT’ or ‘:TEST’ or however you run it.

Of course you can add more commands, but use the elseif function, like this.

Players.PlayerAdded:Connect(function(p)
	p.Chatted:Connect(function(m)
		local args = string.split(m, ' ');
		
		if string.lower(args[1]) == Prefix..'test' then
			if CheckIfAdmin(p) == true then
				print('Test Works!');
			end
		elseif string.lower(args[1]) == Prefix..'test2' then
			if CheckIfAdmin(p) == true then
				print('Test 2 works!');
			end
		end
	end)
end)

Also, this simple admin system does support GUIs. I will show a quick example.

elseif string.lower(args[1]) == Prefix..'message' then
			if args[1] then
				table.remove(args,1);
				local message = game.Chat:FilterStringForBroadcast(table.concat(args, ' '));

				if message then
					local UI = Instance.new('Message');
					UI.Parent = workspace;
					UI.Text = p.Name..': '..message;
					wait(6);
					UI:Destroy();
				end
			end
		end

It makes the standard ROBLOX message GUI and shows the message to everybody in the server.

FULL CODE

local Players = game:GetService('Players');
local Prefix = ':'; -- What goes in front of every command that is ran
local Admins = {game.CreatorId};

function CheckIfAdmin(plr)
	for i = 1, #Admins do
		if Admins[i] == plr.UserId or Admins[i] == plr.Name then
			return true;
		end
	end
	
	return false;
end

Players.PlayerAdded:Connect(function(p)
	p.Chatted:Connect(function(m)
		local args = string.split(m, ' ');
		
		if string.lower(args[1]) == Prefix..'test' then
			if CheckIfAdmin(p) == true then
				print('Test Works!');
			end
		elseif string.lower(args[1]) == Prefix..'test2' then
			if CheckIfAdmin(p) == true then
				print('Test 2 works!');
			end
		elseif string.lower(args[1]) == Prefix..'message' then
			if args[1] then
				table.remove(args,1);
				local message = game.Chat:FilterStringForBroadcast(table.concat(args, ' '), p);

				if message then
					local UI = Instance.new('Message');
					UI.Parent = workspace;
					UI.Text = p.Name..': '..message;
					wait(6);
					UI:Destroy();
				end
			end
		end
	end)
end)

I will be making an advanced admin system tutorial soon. Let me know if this tutorial helped!

I think you should update the tutorial because message is deprecated.
