How To Checks A Scripts Parent

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


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.


@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.

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.

And a little older yet useful topic:

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

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")

Should work with detecting something in the coregui

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