Graphics Bindings for Scala Native

This repository hosts Scala Native bindings to the popular graphics programming libraries SDL2 and OpenGL. With these, you can develop high-performing graphical software, such as games, in your favorite language.

The bindings are designed to reproduce as much as possible the original programming interface in C. In particular, they won't hide Scala Native interoperability types behind regular Scala types. These bindings are only meant to provide access to these libraries for pure Scala Native projects. As such, they expose the low-level details of the underlying API and they might not be suitable for use in platforms that are not supported by Scala Native. If you are looking for a truly cross-platform solution, the ScalaGL project aims to provide a cross-platform (Native, JS, JVM) OpenGL wrapper. Alternatively, The Scala Game Library is a complete 2D Scala game engine with cross-platform support, which uses the SDL2 and OpenGL bindings for its Scala Native backend implementation.

To get started, have a look at the examples folder containing runnable demo projects. They demonstrate how to use the different librairies and extensions.

SDL2

Add this to your build.sbt:

libraryDependencies += "com.regblanc" %%% "native-sdl2" % "0.2"

The bindings export most of SDL2 standard functionalities. Importing

import sdl2.SDL._
import sdl2.Extras._

is pretty much equivalent to

#include "SDL.h"

SDL2 extensions can be provided as separate dependencies. Currently, we have an implementation of SDL2_image and SDL_ttf, which can be included in your project with:

libraryDependencies += "com.regblanc" %%% "native-sdl2-image" % "0.2"
libraryDependencies += "com.regblanc" %%% "native-sdl2-ttf" % "0.2"

For more documentation, you should refer to the official documentation of SDL, as the bindings maintain almost the exact same interface.

OpenGL

OpenGL functions up to 4.6 are exported.

Add this to your build.sbt:

libraryDependencies += "com.regblanc" %%% "native-opengl" % "0.2"

You will also need to add an additional linking option, which will vary depending on your system. For Linux, add the following to your project:

  nativeLinkingOptions += "-lGL"

And for OSX, add the following instead:

  nativeLinkingOptions ++= Seq("-framework", "OpenGL")

The bindings export all of the OpenGL standard up to 4.6. Importing

import opengl.GL._
import opengl.Extras._

will bring all of the standard functions and definitions of OpenGL.

For more documentation, you should refer to the official documentation of OpenGL, as the bindings maintain almost the exact same interface.

OpenGL ES

Coming soon..
