Sprawl game engine

A 2D game engine built to implement Neon Rain.

Setup

Sprawl requires SDL3 and SDL3_image to run. Instructions for compiling them from source via CMake follow.

SDL setup

1. git clone git@github.com:libsdl-org/SDL.git
2. mkdir SDL/build
3. cd SDL/build
4. cmake path/to/SDL
5. make all
6. sudo make install

SDL_image setup

1. git clone git@github.com:libsdl-org/SDL_image.git
2. mkdir SDL_image/build
3. cd SDL_image/build
4. cmake path/to/SDL_image
5. make all
6. sudo make install

After installing both, you may need to update your shared library cache:

sudo ldconfig
