Setting values on the client wont kick the player

oh ok then ill just make it server sided where they cant access it

Most changes made on the client do not replicate to other clients.
See: Roblox Client-Server Model

You will need to send data from the client to the server or kick the player from the client, neither of which can be fully secured.

That’s not true, it still wouldn’t replicate since it’s a server side script.

Read the thread I’ve linked in my last reply please.

Can destroy descendants of the player’s character model , including individual server scripts, textures, and joints!
