Nothing

Quick Start

$ nix-shell              # Only on NixOS
$ mkdir build
$ cd build/
$ cmake ..
$ make
$ ./nothing ../levels/level-01.txt
$ ./nothing_test

Editing Levels

Generally creating a level looks like:

SVG File -> Custom Level File -> Game

To convert SVG to the level file install xqilla and run svg2rects.xqe script:

$ xqilla ./devtools/svg2rects.xqe -i <svg-file> -o <level-file>

All of the levels reside in the ./levels/ folder. Use ./levels/Makefile to automatically rebuild all levels.

Level Editing Workflow

$ inkscape ./levels/level.svg &
$ ./build/nothing ./levels/level.txt &
$ cd ./levels/
$ make watch
Edit Level in Inkscape and Save
Switch to the Game and reload level by pressing Q
Go to 5

Build on Windows

You need to install conan and Visual Studio 2017.

Dependencies

Current version of SDL2/2.0.5@lasote/stable in the conan-transit repository is not compatible with the latest conan, so you'll need to install it locally from the git repository:

$ git clone https://github.com/lasote/conan-sdl2.git # temporary, I hope hope hope
$ cd conan-sdl2
$ conan export SDL2/2.0.5@lasote/stable

Building

Execute the following commands inside of the nothing directory:

$ conan install --build missing --install-folder build
$ cd build
$ cmake .. -G "Visual Studio 15 2017 Win64"

After that, build the build/nothing.sln file with Visual Studio.
