MinecraftC

About

Minecraft is Mojang Studios' sandbox game, first released in alpha in 2009 and formally released for PC in November 2011. MinecraftC is a C port of Minecraft Classic version 0.0.30a, built with SDL2 and OpenGL 1.1 for Windows, macOS and Linux, and includes the original music and sounds. It comes in a vanilla build and a modded build that offers optional raytracing.

How it differs from the original

The modded build adds raytracing using an 8-bit distance field, which the author says sometimes outperforms the original. Survival mode was removed, saving and loading are not implemented, and a few sounds play at the wrong pitch.

Getting started

Prebuilt binaries for Windows (32- and 64-bit) and macOS (x86_64 and ARM) are on the GitHub releases page. To turn on raytracing, use the modded binary and enable it in the mods screen under options; building from source uses CMake, and the Linux instructions are marked untested.

Known issues & limitations

• gameplay: Survival mode was removed for simplicity and compatibility with raytracing.
• audio: A few sounds have the incorrect pitch; cute_sound.h is awaiting pitch shifting implementation.
• features: Load file and save file are not implemented.

Media

Modding & tools

• A bundled script regenerates embedded resource headers when mod authors change or add PNG or OGG files.

Additional notes

Performance

The author reports 60+ fps at 1080p with raytracing on the integrated graphics cards they tested.
