M4KC
Minecraft 4K - C Rewrite
For those who don't know, Minecraft 4K was a stripped down version of Minecraft submitted by Notch to the Java 4K Game Programming Contest, where each submission had to be under 4 kilobytes in size. Its wiki page can be found here.
Being so small, the game proved somewhat easy to de-compile and edit. Multiple people have given this a go, including me.
This project is an attempt to translate the game into C in order to increase its performance, and to provide a platform upon which to add new features.
Bug list
- "Sticky" block collision - this behavior is present in the original version and I have been trying to work out ways to fix it for a while.
- Block outline cuts off at mouse x position.
Goals for this project
- Maintaining the original look and feel as closely as possible.
- Keeping the final executable under 10 KB (on Linux, with the system I have set up in the makefile)
- More blocks
- Perlin noise terrain generation (water, caves, etc)
- Infinite worlds, possibly vertically too
- Mobs and multiplayer (this would require changing the rendering engine to some degree)
- Day/night??? I don't know whether or not this would change the look or feel too much.
Dependencies
Bare minimum to make this code run
- SDL2
- A C compiler
To get it down to a small size, you need
- gcc (have not tried the flags with other compilers)
- gzexe
Places
There is a forum thread for this project here
I will be uploading binaries here
