You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? I want to detect the player’s movement input from the server side, while the character model is in ReplicatedStorage
What is the issue? I can use UserInputService and remotes to send the input from local side to server, but if the player spams it, it will lag the whole server and cause bugs
What solutions have you tried so far? I tried using the character’s humanoid’s Running signal, but it does not work if the character is in ReplicatedStorage
In conclusion, I am trying to get player’s movement input on the server while the character model is in the ReplicatedStorage (or ServerStorage) without using RemoteEvents.
It doesn’t fail that often (read the documentation page i sent it explains when it fails) but if you need really precise input there are better ways than handling it on the server
