[Help] Client vs server files

[Briglair]

I sort of explained this to a similar question a while ago:

[SOLVED] Difference between client and server scripts (setting player hp as admin)

I’m probably not going to explain this very well, but I will try my best! The client and server as two completely separate things. The server code is well… the server. The client code is the code that is running on each and every client. The server has no idea about the game. The server only relays internet traffic between the clients. The server can tell clients what to do by triggering events on the client(s). You can only use native GTA functions on the client side (because the server doesn…

What is the difference between a client and server file, more-so, when should I use one over the other?

You would need to use both. As I said in the other post, the server has no idea about the game or the player. The server simply relays traffic between the players.

@Troye

I was under the impression that code contained inside a server file will execute on the server and affect all players

This is incorrect (sort of). The server can trigger a client event (on all clients), which will run some code.

@Troye

client files only execute locally and not on the server

This is correct. Clients can also trigger to run an event on the server.

@Troye

Do all of the natives work in both file types or are some exclusive to one?

All of the natives are client-side only (because they are native to the game). You can see everything here Native Reference - Cfx.re Docs Plus, you can also see a CFX section. Those are not natives exactly. They are added by FiveM and have a description saying whether they are client, server, or shared. Otherwise, everything else on there is client.
