Using libgdx with Scala - s76/libgdx GitHub Wiki
Scala is a functional, object-oriented programming language for the JVM that works seamlessly with Java libraries, frameworks, and tools. It has a concise syntax and a REPL, which makes it feel like a scripting language, but it is being used in mission critical server software at companies like Twitter and LinkedIn.
Although Scala and Java code can be freely mixed, the standard tooling for working with Scala is quite different than what Java developers will be used to. There is a project, libgdx-sbt-project, that provides a simple path for getting started with libgdx and Scala using standard build tools and best practices.
This tutorial assumes you have installed g8 and sbt 0.12, which are used in the Scala community for generating and interacting with projects.
Setting up a new project
In your favourite shell type:
$ g8 ajhager/libgdx-sbt-project.g8
After filling in some information about your project, you can start placing your game's source files and assets in common/src/main/scala and common/src/main/resources, respectively.
Managing your project
Update to the latest libraries:
$ sbt
> update
Run the desktop project:
> desktop/run
Package the desktop project into single jar:
> assembly
Run the android project on a device:
> android/start
Visit android-plugin for a more in-depth guide to android configuration and usage.
Run the ios project on a device:
> ios/device
Visit sbt-robovm for a more in-depth guide to ios configuration and usage.
Using unit tests
Run all unit tests from desktop, android and common (subdirectories src/test/scala):
> test
Run specific set of unit tests:
> common/test
Using with popular IDEs
In most cases you will be able to open and edit each sub-project (like common, android or desktop), but you still need to use SBT to build the project.
See here for details about sbt plugins for each editor.
