Build instructions

You need to download these libraries yourself and place their source files to the following directories. They are required for any platform.

library	files	destination
LodePNG	lodepng.h and lodepng.c	source/lodepng/
cglm	include/cglm/	source/cglm/
cNBT	buffer.c, buffer.h, list.h, nbt_loading.c, nbt_parsing.c, nbt_treeops.c, nbt_util.c and nbt.h	source/cNBT/
parson	parson.h and parson.c	source/parson/
M*LIB	any root *.h	compiler include path

Wii

For the Wii platform you need to install the devkitPro Wii/Gamecube environment. Additionally install zlib using pacman of devkitPro.

dkp-pacman -S wii-dev ppc-zlib

To build, simply run make in the root directory. You might need to load the cross compiler env first (required e.g. if you use fish instead of bash).

source /etc/profile.d/devkit-env.sh
make

There should then be a .dol file in the root directory that your Wii can run. To copy the game to your apps/ folder, it needs to look like this:

│   ├── terrain.png
│   ├── items.png
│   ├── anim.png
│   ├── default.png
│   ├── gui.png
│   └── gui2.png
├── saves
│   ├── world
│   └── ...
├── boot.dol
├── config.json
├── icon.png
└── meta.xml

GNU/Linux

The game can also run on any PC with support for OpenGL 2.0 and played with keyboard and mouse.

Building requires the following additional libraries, which you can install with your system package manager: zlib, glfw3 and glew. You can then use CMake and gcc to build. The already existing Makefile is for the Wii platform only and might be removed sometime later.

mkdir build_pc
cd build_pc
cmake ..
make

Please also copy the fragment and vertex shaders from resources/ next to your assets/ directory.
