If for ex, there was maybe an event that does something on a serverscript idk, then some exploiter wanted to mess around and put the wrong parameters on the firing of the event and if the server couldn’t find the parameter he put wrong, does the server get affected by this or will it just move on?
If the client is firing into a RemoteEvent that only handles that client’s information/data, it would not mess up the function for any other players. There are a few caveats to this, but most likely if you are handling your code well, nothing should be effected. Still, it is recommended to write the server’s handling of RemoteEvents in a way that, if an exploiter were to run the event with custom parameters, the server should check to ensure nothing is happening that shouldn’t be.
Bottom line: each function run off an event in Roblox Lua could error, but the function could be run again and again. If a RemoteEvent errors, that RemoteEvent will continue running for other players, and even the player who it errored for.
