Is there any possible way for someone to change a value in their player by exploiting?
Like for example, kills and cash in a leaderstat folder, can they change the number value in those? I’m pretty sure they can change their values, but wouldn’t it only appear locally for them and not change the real value?
Yup it won’t. It won’t change datastores too.
As long as you don’t have a remote that lets them arbitrarily increase their stats you’re smooth
From experience, try to create practices where you do server-sided checks to see if they can afford an item to buy, for example. I’ve had a handful of bad practices (and still do sometimes) of basically running checks on the client to see if they can afford something, and if they can, call a remote to buy the item.
That can easily be exploited, so just try to do all that on the server by maybe using RemoteFunctions so you receive input if the purchase was successful or not (again, just an example.)
They can only change it localy so the server won´t change. The other pople dooesn´t see it aswell. so it´s just visual for the hackers. Unless they have a backdoor / Serverside Accsess.
