Minecraft4k for Wasmcraft

This is the source code for the "Minecraft in Minecraft" demo shown off for Wasmcraft 2. It is a heavily modified C++ rewrite of Minecraft4k-Reversed.

Building

You will need some dependencies first. Using apt:

$ sudo apt install clang lld wabt libsdl2-dev

Or using pacman:

$ sudo pacman -S clang lld wabt sdl2

Copy the mcinterface.h file from Wasmcraft 2 to the root of this directory. Then, simply run sh build.sh. This will make 3 main files.

• build/Minecraft4k is a normal binary that uses an SDL2 shim to show what the program should look like without actually running it in Minecraft
• build/Minecraft4k.wasm is a WebAssembly file. This is the file you will provide to Wasmcraft.
• build/Minecraft4k.wat is a text version of the WebAssembly output, occasionally useful for debugging or hand optimization.

Note that there is no mouse movement support yet, though breaking blocks works.
