About

This is a simple game engine that was built to run bare-metal on a Raspberry Pi 3. Using the Raspberry Pi's UART hardware, the games can be played through a serial terminal, and create colored text graphics with ANSI codes.

Demo

A menu and two games are included as examples, controlled using the WASD and Space keys.

Menu (Epilepsy warning: has quickly cycling colors)

Snake

Tic-Tac-Toe

Design

The game engine was architected with platform-specific details (timer, terminal) abstracted out so it could also be implemented and compiled for desktop, which is easier to test and debug. The platform-specific dependencies are injected in main.c based on compiler flags.

Building

Building can be done with make raspi3, or make gcc for desktop. Making raspi3 requires the Linaro arm-none-eabi-g++ cross compilation toolchain.
