so what i mean is not a regular gui that you make i was thinking i saw this somewhere where it pops up with some text and goes away it looks like the box that a friend request looks like i feel like jailbreak uses this is there some line of code that i could make this happen like the kick command player:Kick() or has jailbreak created there own gui?
You're thinking of notifications. To make a notification you need to get StarterGui
and then do
SetCore("SendNotification" , {Content}). They're really useful for small things.
Ex:
game.StarterGui:SetCore("SendNotification", { Title = "Alert", Text = "Hello!", -- Icon = "", You can add an image too but that's not needed Duration = 5, })
I can't really explain it well but here's some more info about them: https://developer.roblox.com/en-us/api-reference/function/StarterGui/SetCore
