Im amazed

What kind of script it is?

And why tf are you making the player variable like that?

[shrewd condor]

Looks like this might be a server script, and you added PlayedAdded:Wait() to fix player being nil. The original issue in this case is that the server has no concept of a LocalPlayer. And "fixing" it by using PlayedAdded:Wait() just gets the first player that joins the server

The server cannot access a players mouse

This is only available on the client

Easiest solution would be to make this a local script, and throw it in StarterPlayerScripts

Use
repeat task.wait until player ~= nil
