# izanagi

A run-and-gun shooter inspired by Metal Slug.

## Setup

> **Note:** CMake and OpenSSL are required. 

### Windows

The following tools are required:

* CMake
* Ninja
* Clang
  > Set your `CC` environment variable to the full path of `clang-cl.exe`
 
  > Set your `CMAKE_MT` environment variable to the full path of `mt.exe`, which can be found on your Windows SDK
	> installation folder (usually `C:/Program Files (x86)/Windows Kits/10/bin/10.0.19041.0/x86/mt.exe`)

1. Clone this repo.
2. Clone the repositories under `dependencies.txt` except for SDL2.
3. Unpack the **MSVC** archive under `dependencies` folder in this project's root. Rename the directory as `SDL2`.
4. Build the following dependencies first:
   - `portmidi`
   - `libwebsockets` (follow the [instructions on building LWS](https://libwebsockets.org/lws-api-doc-master/html/md_README_8build.html))
5. Build via CMake.

### macOS/*NIX

1. Clone this repo.
2. Clone the repositories under `dependencies.txt`, including SDL2.
3. Build the SDL, SDL_image, and SDL_ttf dependencies using the [build instructions for Linux/UNIX](https://wiki.libsdl.org/SDL2/Installation#linuxunix)
   or [build instructions for macOS](https://wiki.libsdl.org/SDL2/Installation#macos).
   > **Note:** You may need to download other tools to build the libraries:
   > - autoconf
   > - make

   > **Note:** Clone the submodules under SDL_ttf to download freetype and harfbuzz:
   >
   > ```shell
   > git submodule update --init --recursive
   > ```
4. For OpenSSL, simply run:
   ```shell
   ./Configure
   make
   make test
   ```
5. Build the following dependencies first:
   - `portmidi` (Linux needs [ALSA libraries](https://www.alsa-project.org/files/pub/lib/) to be compiled)
     - ALSA Lib requires `libtool` to be compiled.
   - `libwebsockets` (follow the [instructions on building LWS](https://libwebsockets.org/lws-api-doc-master/html/md_README_8build.html))
6. Build via CMake.
