SpaceBlaster is a free, unlicensed game inspired by "Space Invaders," developed in Java. It was created to explore and learn more about the LibGDX framework.

The game currently features:
- A modest variety of enemy types with easy future expandability
- A limited selection of weapons obtainable from enemies
- A movement system inspired by Space Invaders
- A life and health system
- Episodes and levels
- Simple and straightforward level editing through text files
- Difficulty settings
- Menus
- Effects created using the LibGDX particle system
The game bundles a Java Runtime Image with it on build, meaning the end user doesn't need to have Java installed on their machine, as long as they get the distribution for the correct operating system.
You need maven and java 12 JDK installed on your machine. Build the game using maven:
For windows version: mvn clean package -Pwin
For unix/mac version: mvn clean package -Punix
The application will be ready to distribute under {project.folder}/desktop/target/dist
To build Unix version on Windows, or vice versa, you need to have toolchain configured
on your machine for the target version. https://maven.apache.org/guides/mini/guide-using-toolchains.html
and the necessary JDK present in your computer.
So, when you configure the toolchain you pass the necessary values to maven build with the dist.jdk VM argument
-Ddist.jdk=key1=value1,key2=value2
For example if I wanted to build Unix distribution on Windows machine :
mvn clean package -Punix -Ddist.jdk=version=10,vendor=openjdk,platform=linux-x64
Yes, just remove or comment out the create-runtime-image execution from pom.xml in spaceblaster-desktop module.
Then change the run.sh and run.cmd files under bin folder to invoke general java instead of java subfolder.
This then works without bundled java, assuming computer knows where to find java. In that case you also don't need
to have toolchains configured and can create cross-platform version of the game on either OS.
As of June 2024, SpaceBlaster includes an event system that allows players to record their gameplay as events saved to disk. These events provide an overview and timeline of the played game.
To enable the event system:
Edit the spaceblaster.yaml file in the root directory of the built game. Set eventMode to true.
This will save the gameplay recordings to the eventlogs folder.
The event system is meant to be used for experimental augmentation by AI.
