# Nothing
+## Dependencies
+
+- [gcc]
+- [cmake]
+- [libsdl2-dev]
+- [inotify-tools]
+
+### Ubuntu
+
+```console
+$ sudo apt-get install gcc cmake libsdl2-dev inotify-tools libxml2-dev
+```
+
+### MacOS
+
+```console
+$ brew install gcc cmake sdl2
+```
+
+### NixOS
+
+For [NixOS] we have a development environment defined in [default.nix]
+with all of the required dependencies. You can enter the environment
+with `nix-shell` command:
+
+```console
+$ nix-shell
+```
+
+### Arch Linux
+
+```console
+$ sudo pacman -S gcc cmake sdl2 inotify-tools libxml2
+```
+
+### Windows
+
+- [Visual Studio 2015+](https://visualstudio.microsoft.com/)
+- [SDL2 VC Development Libraries](https://www.libsdl.org/release/SDL2-devel-2.0.9-VC.zip)
+
## Quick Start
+### Linux
+
```console
-$ nix-shell # Only on NixOS
$ mkdir build
$ cd build/
$ cmake ..
$ make
-$ ./nothing ../levels/level-01.txt
-$ ./nothing_test
+$ cd ../data/
+$ ../build/nothing
+```
+
+### Windows
+
+- Enter the Visual Studio Command Line Development Environment https://docs.microsoft.com/en-us/cpp/build/building-on-the-command-line
+ - Basically just find `vcvarsall.bat` and run `vcvarsall.bat x64` inside of cmd
+- Download [SDL2 VC Development Libraries](https://www.libsdl.org/release/SDL2-devel-2.0.9-VC.zip) and copy it to `path\to\nothing`
+
+```console
+> cd path\to\nothing
+> 7z x SDL2-devel-2.0.9-VC.zip
+> move SDL2-2.0.9 SDL2
+> mkdir build
+> cd build
+> cmake ..
+> cmake --build .
+> cd ../data/
+> ..\build\nothing
```
## Controls
| `q` | Reload the current level preserving the Player's position |
| `p` | Toggle game pause |
| `l` | Toggle transparency on objects. Useful for debugging levels |
+| `TAB` | Switch to Level Editor |
#### Gamepad
| `Enter` | Evaluate the expression |
| `Up/Down` | Traverse console history |
-## 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:
-
-```console
-$ 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
-
-1. `$ inkscape ./levels/level.svg &`
-2. `$ ./build/nothing ./levels/level.txt &`
-3. `$ cd ./levels/`
-4. `$ make watch`
-5. Edit Level in Inkscape and Save
-6. Switch to the Game and reload level by pressing Q
-7. Go to 5
-
-### Objects Reference
-
-#### SVG rect node
-
-| Regex of id | Description |
-|--------------|-------------------------------------------------------------------------------------------------------------------|
-| `player` | Defines the **position** of the Player. **Size is ignored**. |
-| `rect.*` | Defines the **size** and **position** of an impenetrable platform block |
-| `box.*` | Defines the **size** and **position** of a rigid box that obeys the physics of the game |
-| `region(.*)` | Defines the **size** and **position** of a region that hides the Goals. `\1` defines the id of the Goal to hide. |
-| `goal(.*)` | Defines the **position** of the goal. **Size is ignored**. `\1` defines the id of the region that hides the goal. |
-| `lava.*` | Defines the **position** and **size** of a lava block. |
-| `background` | Defines the **color** of the background. **Position and size are ignored**. |
-| `backrect.*` | Defines the **size** and **position** of a solid block in the background. |
-
-#### SVG text node
-
-| Regex of id | Description |
-|-------------|----------------------------------------------------------------------------|
-| `label.*` | Defines **position** and **text** of a in-game label. **Size is ignored**. |
-
-## Build on Windows
-
-You need to install [conan][] and [Visual Studio 2017][visual-studio].
-
-### Dependencies
-
-Current version of [SDL2/2.0.5@lasote/stable][conan-sdl2] in the conan-transit
-repository is not compatible with the latest conan, so you'll need to install
-it locally from the git repository:
-
-```console
-$ 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:
-
-```console
-$ 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.
