A SDL2 implementation of the classic Pong game with a simple network support.

Contains a single mode where two human players can play againts each other.

Contains a single scene.

This Pong implementation contains the following features.

• A support for TCP and UDP transport protocol.
• Each launched game instance acts either as a server or client.
• Each game lasts until either player receives the 10th point.
• Both paddles are controlled by human players.
• Ball velocity is increased on each hit with a paddle.
• Ball movement is being stopped for ~1 second after each reset.
• Ball direction is randomized from four different direction after each reset.
• Paddles are returned to their default position after each reset.

This implementation has external dependencies on the following libraries:

• SDL2
• SDL2net

Easiest way to compile the code is to use the provided Makefile.

Makefile may require some modifications based on the compilation environment.

Game startup syntax is as following.

pong.exe [transport-protocol] [host]

An example to start a TCP server.

$ pong.exe tcp

An example to start a TCP client and connect to a localhost.

$ pong.exe tcp localhost

There are some major notes and bugs in the current implementation:

• Implementation uses remote lag as the latency compensation mechanism.
• Implementation has some minor timing problems (shown as jittering) at the start.
• Implementation does not include reliability control for UDP.
