What is FastJ?

FastJ is an open-source, Java-based 2D game engine and framework. Originally named the FastJ Engine, it aims to provide an easy-to-use, 2D game-making library.

Disclaimer

This project is still under heavy development. There is a very good chance bugs are still prevalent and untracked, as the engine is not fully covered by unit tests. Documentation is readily available, but may change over time. Feel free to help us out by contributing to the project!

Get Started

There are many different ways to learn FastJ -- check them out!

Template Projects

Use a template project! It's the fastest way to jump into using FastJ.

Choose a programming language from the ones below. We suggest Java, as it has the most support:

Java: https://github.com/fastjengine/fastj-java-template

However, Kotlin and Groovy are reasonable options as well:

Tutorials

FastJ provides article tutorials on its website to accommodate as many types of developers as possible. From beginners to experts, the website tutorials are written to give enough information to satisfy anyone willing to learn!

Code Examples

Explore FastJ's code examples to see the different ways FastJ can be used, and all of its features. These come with in-example explanations and easy plug-and-playability to give you the best chance at understanding how FastJ works.

API Documentation

Check out FastJ's documentation to get a better understanding of the code FastJ provides to improve your game-making experience.

I'll add the dependency myself!

Ok, ok, I hear ya. To do so, just follow through with these instructions below.

Dependency Management

This library can be found in the following places:

jitpack.io, as a dependency.
Maven Central, as a dependency or as a jarfile.
The Releases section of this repository.

When adding the dependency, make sure to replace [latest version here] with the actual version (you'll find this in the jitpack.io or Maven Central link up above). The current latest version is 1.6.0.

A few common dependencies are provided below:

Gradle Build Script

Groovy:

repositories.maven {
    url('https://jitpack.io')
}

dependencies.implementation('com.github.fastjengine:FastJ:[latest version here]')

Kotlin:

repositories.maven {
    setUrl("https://jitpack.io")
}

dependencies.implementation("com.github.fastjengine:FastJ:[latest version here]")

Maven POM

<repository>
  <id>jitpack.io</id>
  <url>https://jitpack.io</url>
</repository>

<dependency>
  <groupId>com.github.fastjengine</groupId>
  <artifactId>FastJ</artifactId>
  <version>[latest version here]</version>
</dependency>

You'll also want to make sure you add a dependency for a logging framework from SLF4J, since FastJ uses it for all its logging purposes. Take your pick!

Hello World Code (Java)

import tech.fastj.engine.FastJEngine;
import tech.fastj.graphics.display.FastJCanvas;
import tech.fastj.systems.control.SimpleManager;

public class HelloFastJ extends SimpleManager {

    @Override
    public void init(FastJCanvas canvas) {}

    @Override
    public void update(FastJCanvas canvas) {}

    public static void main(String[] args) {
        // Creates an empty window titled "Hello, FastJ!"
        FastJEngine.init("Hello, FastJ!", new HelloFastJ());
        FastJEngine.run();
    }
}
