![]() ![]() This is a sign that you’re doing it right even if it seems like that’s wrong. If the client places an item they don’t have they should see it before the server tells them to remove it. Sometimes you need to resync the client such as for placing an invalid object. The server must verify that this action is allowed using the same code the client does. You want the client to mimic your server code by itself and then notify the server that it performed the action. You can think of the client like a mini version of the server that the player has control over. The client should always “pretend” like it’s right. ![]() All remote traffic from and to your client is visible to the exploiter! Networking your game What code should you run on the client? That means they can even intercept the data that your client receives from or sends to the server. That means any client side checks you place on the client can just be removed by an exploiter and the values it checks can also be changed! Any functions you call on an instance or from the global libraries like math and table can be changed by the exploiter without you ever knowing. Keep in mind, since the bytecode for server scripts (and module scripts located in ServerStorage and ServerScriptService) are not sent to the client, they can’t be decompiled! Never trust the client!Īn exploiter has access to the client side code in your game and can change all of it’s functionality, whether that be editing the script somehow, or changing the values and functions it uses. This absent information would make the decompiled code much easier for an exploiter to read. That means any information which is not included, like local variable names and comments also cannot be decompiled. The fact that this code is stored in memory and an exploiter has access to it also means it can be “decompiled.” A decompiler on a basic level just tries to create lua code which produces the same bytecode when compiled. This bytecode and the values and functions the bytecode accesses can be changed at any time. When you write your game’s lua code it will be compiled when the game starts and each LocalScript’s (and ModuleScript’s!) bytecode will be sent to the client. It’s a version of the lua code called “bytecode” which the client can interpret. This “code” isn’t like the lua code that you write though. And that code is stored in the client’s memory. That means this code must be stored somewhere for the client to use it. The server has to send some kind of code to the client so that the client can run this code. Most developers when they first start learning about game security will ask, “Why can’t exploiters just be stopped with a script on the client?” Well think about it like this. I’m going to explain this phrase and give some useful information about remote and client security as well as give some information about effective anticheats. You may have seen the “never trust the client” phrase tossed around if you’ve read or created scripting support threads about remotes or game security. This is a super long thread so read it at your own pace. You can find more info and the repo links here: Hexolus' Server-sided Anticheat It will not work for Windows Store version.I’ve now open sourced an implementation of one of my anticheats for use in my game Hexolus! Why it doesn’t work with the Windows Store version of the game?īecause it was made only for the website version of the game engine. ![]() Some scripts are also not supporter for long time use. For example the fly script uses too much RAM and eventually it will crash the game. Some of the scripts uses too much RAM and therefore it crashes the game in the middle of a game. JJSploit crashing in the middle of the game. However, if you want an Android Roblox executor then try Arceus X and Hydrogen executor both are awesome Android Roblox executors. Sometime restarting your computer may work. This may sometime takes few tries before you get it working again. If the program keep on crashing on injection, please close the game for 30 seconds before rejoinging the game. Please disale your anti-virus program to get the update. If you still didn’t get the update within 6 hours, it means something is blocking JJSploit to get the update. However, sometime it takes 6 hours max to get the update. The dev behind JJSploit usually release the update within an hour. It is because the game updates every week or more often and therefore JJSploit need to be updated too. Why does it say game engine version mismatch? You should disable your antivirus or whitelist the JJSploit. Though anti-virus program can glag it as virus but it’s due to the nature of the program. JJSploit is created by none other than WeAreDevs, so you can trust on the safety matters. ![]()
