Remove notifications, reset button, and more

ptitloup132 · January 1, 2026, 11:55pm

Hello,

I’m trying to remove the reset button from roblox UIs using SetCore from StarterGui service but… getting this error :

 00:53:32.278  CoreGui.RobloxGui.CoreScripts/FriendPlayerPrompt:215: Invalid argument to PromptSendFriendRequest  -  Client

Sometimes the script is not able to remove the reset button :

 00:55:00.025  SetCore: ResetButtonCallback has not been registered by the CoreScripts  -  Client - DisableRobloxUI:13
  00:55:00.025  Stack Begin  -  Studio
  00:55:00.025  Script 'Players.ptitloup132.PlayerScripts.DisableRobloxUI', Line 13  -  Studio - DisableRobloxUI:13
  00:55:00.025  Stack End  -  Studio

Code:

local plr = game:GetService("Players").LocalPlayer
local StarterGui = game:GetService("StarterGui")

plr.CharacterAdded:Wait()

StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Backpack, false)
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.EmotesMenu, false)
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.PlayerList, false)
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Captures, false)
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Health, false)


StarterGui:SetCore("ResetButtonCallback", false)
StarterGui:SetCore("PointsNotificationsActive", false)
StarterGui:SetCore("BadgesNotificationsActive", false)
StarterGui:SetCore("SendNotification", false)
StarterGui:SetCore("DevConsoleVisible", false)
StarterGui:SetCore("PromptSendFriendRequest", false)
StarterGui:SetCore("PromptUnfriend", false)
StarterGui:SetCore("PromptBlockPlayer", false)
StarterGui:SetCore("PromptUnblockPlayer", false)

Alright, this might be a bit hacky, but would this work?

while not pcall(StarterGui.SetCore, StarterGui, "ResetButtonCallback", false) do
	task.wait()
end

ptitloup132 · January 2, 2026, 12:00am

I tried it, I think it works but… is there any other way without a possible infinite loop :> ?

TheeDeathCaster · January 2, 2026, 12:02am

Outside of creating a custom timeout, I don’t think so.

ptitloup132 · January 2, 2026, 12:03am

I’m counting the number of iterations; do you think 5 is enough per “core type”?

TheeDeathCaster · January 2, 2026, 12:03am

That might work. I could write something real quick to help accomplish that.

ptitloup132 · January 2, 2026, 12:04am

local plr = game:GetService("Players").LocalPlayer
local StarterGui = game:GetService("StarterGui")

plr.CharacterAdded:Wait()

StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Backpack, false) 
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.EmotesMenu, false) 
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.PlayerList, false) 
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Captures, false) 
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Health, false)


local function disableCore(coreName)
	local i = 20
	while not pcall(StarterGui.SetCore, StarterGui, coreName, false) and i ~= 0 do
		task.wait(0.1)
		i = i - 1
	end
end

disableCore("ResetButtonCallback")
disableCore("PointsNotificationsActive")
disableCore("BadgesNotificationsActive")
disableCore("SendNotification")
disableCore("DevConsoleVisible")
disableCore("PromptSendFriendRequest")
disableCore("PromptUnfriend")
disableCore("PromptBlockPlayer")
disableCore("PromptUnblockPlayer")

I’ve done this

ptitloup132 · January 2, 2026, 12:08am

I have still some errors… these :

Actually, roblox calls its functions and… by the time I deactivate them they are in calls so… what do I do?

TheeDeathCaster · January 2, 2026, 12:24am

I made a slight change to what I’d written before. Try this out instead:

local listOfCoreGui = {"ResetButtonCallback", "PointsNotificationsActive", "BadgesNotificationsActive", "SendNotification", "DevConsoleVisible", "PromptSendFriendRequest", "PromptUnfriend", "PromptBlockPlayer", "PromptUnblockPlayer"}

local function disableStinkyCoreGui(coreGui, timeOut)
	while not pcall(function() StarterGui:SetCore(StarterGui, coreGui, false) end) and timeOut > 0 do
		timeOut = timeOut - task.wait()
	end
end

for _, coreGui in ipairs(listOfCoreGui) do
	coroutine.wrap(disableStinkyCoreGui)(coreGui, 5)
end

ptitloup132 · January 2, 2026, 12:36am

local plr = game:GetService("Players").LocalPlayer
local StarterGui = game:GetService("StarterGui")

plr.CharacterAdded:Wait()

StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Backpack, false) 
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.EmotesMenu, false) 
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.PlayerList, false) 
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Captures, false) 
StarterGui:SetCoreGuiEnabled(Enum.CoreGuiType.Health, false)


local listOfCoreGui = {"ResetButtonCallback", "PointsNotificationsActive", "BadgesNotificationsActive", "SendNotification", "DevConsoleVisible"}

local function disableStinkyCoreGui(coreGui, timeOut)
	while not pcall(function() StarterGui:SetCore(coreGui, false) end) and timeOut > 0 do
		timeOut = timeOut - task.wait()
	end
end

for _, coreGui in ipairs(listOfCoreGui) do
	coroutine.wrap(disableStinkyCoreGui)(coreGui, 5)
end

It works, but no idea why these core can’t be disabled:

PromptUnblockPlayer
PromptBlockPlayer
PromptSendFriendRequest
PromptUnfriend

The registered by the CoreScripts error disappears if your local script is placed under game.StarterGui. The other error is telling you that you can’t run this part of your code because the arguments are wrong:

StarterGui:SetCore("PromptSendFriendRequest", false)
StarterGui:SetCore("PromptUnfriend", false)
StarterGui:SetCore("PromptBlockPlayer", false)
StarterGui:SetCore("PromptUnblockPlayer", false)

If you comment out that part your code runs without errors.

ptitloup132 · January 2, 2026, 12:44am

Oh, but I’m being silly, I actually thought it was to disable notifications, but no, it’s to make the request… -_-
