Local replication

Local replication is a term used to describe the process of a client sending a signal to the server, which in turn is sent to other clients to replicate different effects with the benefits of local behaviors. For example, if a client generated a projectile visualizer locally, nobody but that player would be able to see it. If the visualizer were on the server, it would be subject to the latency and lower refresh rate of the server, causing janky visuals. When a client wanting to replicate an effect sends the necessary information to the server so that the effect may be generated for a different user by their own client, then you can maintain accurate and smooth visuals processed at your framerate.

To do this, we will need to create a new OnServerEvent event function for the Replicate RemoteEvent in ReplicatedStorage. This should already be defined from when you created the Weapons module earlier. The parameters of this event function are the player who fired...
