A script on how to stop people coming into your game and hacking, is that a thing?

So i need something that can stop people from using scripts in my game, the game is farely new and would like to know if their is a script or anything that can stop them from doing so. I was told earlier today that their is something that can stop that but im not too sure what it is, so he sent me here to get help.

(Sorry my last question wasnt very detailed, if this one isnt ill work harder as im in a rush and quite busy at the moment, sorry!)

Example: Someone joins my Obby and kills me with a command The player manages to swap stages with someone so they have basically skipped half the obby

Just Use FilteringEnabled its a anti exploit/hack developed by ROBLOX to stop hackers you can find workspace in explorer then select it then go in properties and you should see it!
