[CLOSED] Fly Admin Command

Hi! I made a simple Script that is located in ServerScriptService. It looks similar to this:

local Players = game:GetService("Players")
local Prefix = ";"
local Group = 0 --Id of my group here.
local Rank = 255
Players.PlayerAdded:Connect(function(player)
local function Fly(msg)
if msg == Prefix.."fly" and player:GetRankInGroup(Group) >= Rank then
--?
end
end
 local function Unfly(msg)
if msg == Prefix.."unfly" and player:GetRankInGroup(Group) >= Rank then
--?
end
end
player.Chatted:Connect(Fly)
player.Chatted:Connect(Unfly)`
end)

Prefix, Group and Rank is set in ModuleScript, but to make it clear I wrote it down in the Script.

I tried searching DevForum but I found few exaples that were not exactly what I wanted. Can you write the code and explain what does each line do?
Thanks, Jermartyno.

Don’t need help anymore. Made it myself after watching Youtube tutorials, searching DevForum and rescripting everything.
