How do I make Client side scripts such that the script applies to the client, not the whole server?
Example Task (Give script based on this example)
I want a part to go invisible whenever a player touches it, it should go invisible only for the client from whom the player touched, nobody else should see it invisible unless they touch it too
Please give examples of how to use it if its in a part or block and how to use it if its in other places.

But why does it only work if i put it in the starter gui, why no-where else?
It does work on other places such as StarterPack, ReplicatedStorage, StarterPlayerScripts, etc. Just make sure you place it somewhere the client can access.
