How To Checks A Scripts Parent

[Mystery_Devx (IAmMyst)]

Hello,
I am having trouble on how to check when something is added to the game if its parent is

nil

Not on the server but on the client as a way of detecting exploits as most of them parent to CoreGui and nil.

I think I understand what you mean, but I’m afraid that detecting when any instance is added in memory wouldn’t and/or won’t perform well, since game objects with nil as a parent are located in memory, along with all other objects, variables, game instances and more. With events such as ChildAdded and DescendantAdded we can detect added instances inside game environment. You can listen for changes, although stay aware that most client changes don’t replicate across client-server boundary (animations, sounds, click detectors, client simulated physics etc.).

You can surely listen to game changes, but don’t overdo it, both client- and server-side, but don’t overdo it, since that will lead to high resource consumption.

EDIT

@Thigbr

You cannot necessarily do that with coreguis I believe

@Thigbr yes, that is correct. Unless using yet undiscovered bugs, one cannot access CoreGuis. Consequently, we can’t listen for changes either. Detecting unwanted game objects is not practical. We can either listen for changes on specific areas, or scan the whole game data model like you proposed, which is a good idea! However, games can be pretty large and contain numerous parts and other instanced, making such approach slower, thus not to be used constantly.

EDIT (2) @RageOfficial_Support

There are a lot of topics on Dev Forum discussing this same exploit prevention possibility, and pretty much all consider focusing on other exploiting aspects as a conclusion and best practice.

Can't access coregui

I’m making a game that I want protected against exploits. To do this, I came up with an anti-exploiters-gui script that would detect if something unexpected would be inserted into the core gui (via the client). This is what I made: local plr = game.Players.LocalPlayer local AllowedNames = {} game.CoreGui.ChildAdded:Connect(function(Obj) if (not AllowedNames[Obj.Name]) then plr:Kick("Do not cheat.") end end) I know there is nothing inside the AllowedNames table. If I run this, the error …

"Dont have permission" To detect change to CoreGui

CoreGui isn’t accessible to developers. That means you CANNOT get it’s descendants or properties. CoreGui documentation.

CoreGui Anti Exploit Detection

Roblox patched most bugs that allowed developers to detect CoreGui exploits, however, there are ways to detect exploits that have CoreGui GUIs so you could focus on detecting the other parts of whatever exploit is interfering with your game. A good thread that may help you is Exploiting Explained which if you read the post and replies can provide you with good insight into how you can go about protecting your game.

And a little older yet useful topic:

Accessing CoreGui in localscript?

Hello, everyone. I’ve been studying some exploit scripts recently, and I’ve noticed that they inject their interface into the CoreGui. I was wondering if there’s any way to access the CoreGui inside of a localscript so I can ban the player as soon as an object matching that name comes up. Any help would be appreciated.

How about core GUI? Can I use ChildAdded, FindFistChild, Or Descendant Added for coregui or no.

[Thigbr (Sebee23)]

You cannot necessarily do that with coreguis I believe, A lot of exploits use them to crack down to bypass a anti exploit however I believe doing,

local BlacklistedNames = {"Blacklisted name", "Blah blah blah"}
for _,v in ipairs(BlacklistedNames) do
    if game:FindFirstChild(v) then
         print("do something")
    end
end

Should work with detecting something in the coregui

Thanks, will this work if it parents to anything in the game. Even the output?
