How do I make vip sever host commands?

Right know I’m making a fighting type of game and I’m trying to make it so if you buy a vip sever you get host commands what only the vip sever host can access and I don’t know what I’m suppose to script because I’ve never done that before so can someone help me with that?

First you have to check the type of server it is. I'm pretty sure it's like this

if game.VIPServerId ~= "" or game.VIPServerOwnerId ~= 0 then

end

Now that you can find out it it is a vip server or not, it's time to work on the code if it is a vip server.

Also put this code in a server script in ServerScriptService and name it VipServerHandler.

local CommandPrefix = '/' -- Change this to your liking

if game.VIPServerId ~= "" or game.VIPServerOwnerId ~= 0 then
	local buyerId = game.VIPServerOwnerId
	local buyer = game.Players:GetPlayerByUserId(buyerId)

	-- Now the vip commands
	-- I'm not sure if you want support for the command to be case-unsensitive, just let me know if you want
	
	buyer.Chatted:Connect(function(message)
		if message:sub(1,6) == CommandPrefix .. "kick " then 	 
            		game.Players[message:sub(7)]:Kick()
		elseif message:sub(0,0) == CommandPrefix .. "" then
			-- Add more commands yourself
		end
	end)
end

The only important things here is string manipulation and the player.Chatted event.

Note: :sub is spelt with a lower-case s

I hope this helps :)
