Xenon Reborn

The main goal of this project is to offer a basic framework to implement an old school shoot-them-up game. Rookies can practice algorithm and basic Java programming to acquire development skills.

This framework is based on LibGDX and runs only on a desktop computer (Java SE 8) until now.

"XenonReborn" is a classic gradle generated by the LibGdx config tool.

Here is how the v0.1.8 looks like (Youtube) (just click on the image to launch the video)

How to build and run

Clone (or download) the project :

$ git clone https://github.com/fxrobin/xenon-reborn.git

Then enter the directory, then type :

• on linux $ ./gradlew run
• on windows > gradlew run

How to generate de JAR distribution

• In a terminal : $ ./gradlew dist

Then open the browse the file system from the project root directory to "desktop/build/lib"

The generated jar name is "xenon-reborn-v.XX.XX.XX.jar". You can run it directly (after setting the executable bit on Linux with running $ chmod +x xenon-reborn-v.XX.XX.XX.jar in a terminal.

This JAR file includes the game and all its dependencies.
