How to make a set player be able to control a script?

I have an idea to make it so only I (or any set player) is able to access or use a script.

Is there any way to do this via the script or outside of it?

You can enable and disable the script using another script.
So pretty much using a local script and a server script.

Example,
I dont want this player dashing
So on the server I go into their starterplayerscripts and disable that local script.

How ever, this is exploitable on the client.

So I recommend adding a check if you’re trying to add a anti cheat.
Like a server check to see if their script is disabled or not.

You can use something like a global variable to make something only you can access.
local isAdmin = false

game.Players.LocalPlayer.Chatted:Connect(function(msg)
if msg == “!” then
isAdmin = true
end
end)

script.Parent.Touched:Connect(function(part)
if isAdmin then
script.Parent.BrickColor = BrickColor.new(“Bright red”)
end
end)
