* Client-Side-Prediction-Test
|
|
|
|
|
An example of client-side prediction for networked games, as research and
|
|
|
|
|
training for 'Spacewar!'

|
|
** What is this repository for?
|
|
|
|
|
I realized that the current netcode of Spacewar was fine for simply running two
|
|
|
|
|
instances of the game on the same computer; but it would not hold up to
|
|
|
|
|
latencies of actual networks nor would it be able to do any structured
|
|
|
|
|
communication due to being entirely over UDP. I knew this when writing it, but I
|
|
|
|
|
needed to learn how to do it properly first. Hence, this repository. I will be
|
|
|
|
|
keeping notes on the techniques and a devlog as I come up against any issues.

* Developer's Log:
|
|
|
|
|
** Entry 00: Intentions:
|
|
|
|
|
I intend to build a simple networked "game" where players can join a server
|
|
|
|
|
using a client, and then move around in an empty 2D space where they can see
|
|
|
|
|
other players. I intend to have the positional data transmitted over UDP, and
|
|
|
|
|
command data transmitted over TCP, such as allowing the connection and
|
|
|
|
|
disconnection of players. This simulation must be relatively resistant to
|
|
|
|
|
latency issues, and must be reasonably smooth.
|
|
|
|
|
|
|
|
|
|
This will provide a simple enough simulation to learn the techniques, while also
|
|
|
|
|
being similar enough to "Spacewar!" so that it's not too big of a stretch to
|
|
|
|
|
update that project's netcode. It may be cute to have this be some sort of chat
|
|
|
|
|
program, but that's another project for another day.
|
|
|
|
|
|
|
|
|
|
For now, circles moving around in an empty space that move smoothly over network
|
|
|
|
|
connections is the goal. Let's get started!
|
|
|
|
|
|
|
|
|
|
** Entry 01: First Steps:
|
|
|
|
|
I think my first step will be creating the TCP portion of the client-server
|
|
|
|
|
interaction. This should be relatively trivial, so I can get right to it. Simply
|
|
|
|
|
transmitting a few integers back and forth will do well.

|
|
|
|
** Entry 00: Where I'm Learning All This From:
|
|
|
|
|
I'm using a series of articles from gabrielgambetta.com, which seem to be well
|
|
|
|
|
written, and reasonably clear. (So big thanks, Gabriel!) I intend to note my
|
|
|
|
|
understanding as I progress through these articles (while simultaneously
|
|
|
|
|
implementing them), and therefore provide a more practically based version of
|
|
|
|
|
the information. Will it be better? Possibly, though unlikely!
