I recently have been working on an Anti-Exploit Script mainly for the fun of trying new coding experience.

I’ve been wondering what is the best way of going about to script the Hardest parts of the anti exploit script.

  • Anti-Fly
  • Anti-NoClip

I know their are lots of flaws, and ways of going around to check on how to do this. Currently my code is dog water, but still something.

How I set it up^

What is included -

  1. Discord Webhooks.
  2. Banned Table to keep banned kids out of game.
  3. Server Messages to let other players know.

One problem:

If anyone knows how I can actually get it to NOT effect owners, I still don’t understand why this -

	if settingsModule.AllowedPeople[player.Name] then -- If any player is an Admin, they will not be affected.
			return
		else -- Other Players

is not working…

ANY ADVICE HELPS!

Patching an Exploit
My games are getting leaked and ddosed using exploits
#2

A bunch of these checks are pretty much pointless and a few other nitpicks.

  1. Scripts are not subject to roblox censoring (for obvious reasons)

  2. Speed check is useless because if an exploiter changes their speed on the client, the server won’t see it

    This also applies to the Jump height, anti-godmode , anti-btools , anti-naked, anti-loud music, anti-invisible, anti-fog and Camera checks

  3. Reminder to watch for typos

    I think you mean

    if not Character:FindFirstChildOfClass("Shirt") or not Character:FindFirstChildOfClass("Pants")  then

Here’s a hint in making an anti-fly and anti-noclip

For anti-fly you want to figure out how high a player is in the air and if it is too high for too long of time you want to punish them

A simple way of figuring out how high they are is to fire a ray downwards and then seeing where it lands

For anti-noclip you need to figure out if a player’s path intersects a wall so you can raycast from a player’s previous position to their current and see if it hits anything that is not the player.

I like how you approached this problem, keep on working at it!

Okay so pretty much all that is needed is “Anti-Fly” “Anti-Noclip”.

I like that you told me about the client sided way of saying. Even if the exploiters do anything, its mainly client sided?

#4

Use table.find instead.

This would not work since WalkSpeed changes from the client don’t replicate to the server.

Most things they do only show up for themselves but except for some physics information (like parts with their network owner set to players and their character) replicate when changed by the client.

I don’t know about that, because the script →

GodMode,Jump,Speed all work. They kick/ban me.

Ill look at table.find!

#7

if i use this does it make sure that people who have Admin Commands in my game Will not get banned or kicked out?

because i have been looking for an anti-Exploit script for a while and i don’t want people to get mad at me because of it.

hope to hear from you soon

Yes as stated here, in the MODULE SCRIPT → 

AllowedPeople = {				-- This is for the people that get bypassed of Anti-Exploit. (Admins, owners, etc.)
		"TwinPlayzDev_YT",
		"ADMIN",
		"MOD",
		"SPECIAL"
	};

Make sure to change → 

if settingsModule.AllowedPeople[player.Name]

To

table.find

instead.

I know modules are useful and all but I can also change a module when I’m using Synapse X just for your information, just be careful. So in theory if I do it right I can disable this in its entirety.

Ya this is a pretty outdated script. I haven’t used it at all. Just though to use it for fun.

You are right though, synapse can bypass pretty much everything.

#11

Didn’t realize how long ago this was created so my advice wouldn’t even be helpful. But yeah Synapse if you know how to use it you can get past pretty much anything the client can view which makes it difficult.

There solution for anti exploit for who using synapse in your game
It is need Anti-cheat can detected something in coregui

#13

You can’t view the CoreGui, even if you manage to find yourself the CoreGui in a local script it’s for all players, how are you going to get the specific player. EVEN if you manage that. I delete the part of that code with Synapse then inject my UI.

To add onto this:
Checking their position every X seconds is not a bad idea either, this can stop some speed exploiters, but due to server latency, it is not 100% user-friendly.

#15

You cannot access CoreGui, as Naval said above.
In other words: Exploiters use higher context levels to access it, something you are not able to do.

if the module script is in serverscriptservice, its completely useless because exploits cannot access anything or interfere with anything in that place.

Nope! unless the ModuleScript is in a server-only service you cannot unless its a client reachable service you can.

I hate seeing kids think Synapse X can manuiplate stuff in the server

#19

This script is on the server :confused:

#20

Not at all — Synapse X Is just an executor that lets you inject code! with Synapse X you can Inject code that can somewhat bypass it.

Again another kid thinking synapse can do pretty much everything
