Desktop ENet multiplayer

Quest Lessons

9 lessons

The Postcard Problem

25-60 min

Signal Lost is a desktop ENet co-op shooter for two to four players. Begin with browser experiments; Godot starts in lesson 3.

Late, Out of Order, or Never

25-60 min

Arrival order and send order can differ. Some messages never arrive.

Your First Server

25-60 min

Create an empty project with Godot 4.7.2 and the Compatibility renderer. The supplied files completely define its first runnable state.

Two Windows

25-60 min

create_client starts a connection attempt. Only connected_to_server establishes a usable client connection.

Who Just Joined

25-60 min

The server owns the roster. Each client registers its name after connecting, then receives the whole authoritative roster.

The Network Inspector

25-60 min

DebugOverlay keeps a CanvasLayer root. Its Panel/Rows/Header path is explicit in the supplied scene.

Messages, Payloads, and Ping

25-60 min

Application message counts are different from network packet counts. ENet headers, retransmissions, spawns and property synchronization are not measured here.

The Application-Message Dial

25-60 min

The dial delays or drops an application call before it reaches ENet. A dropped reliable call was never submitted for retransmission.

The Bot Client

25-60 min

A bot is another client process using the same connection path. At this stage it logs its ID; no player scene exists yet.

Is This Quest For You?

Perfect for you if:

You know basic GDScript and want to build one multiplayer project step by step.

Not for you if:

You need a production matchmaking service or browser multiplayer transport.
