Start by learning enough Java to read and change a small program, then build a simple desktop game with libGDX. Its official A Simple Game tutorial walks through a bucket catching falling droplets, introducing assets, drawing, input, game logic, and audio without the overhead of a large first project.
What to learn in Java before making a game
You do not need to master Java first. Learn enough to understand and modify a small program: variables, conditionals, loops, methods, classes, object creation, and basic collections. The libGDX tutorials assume some coding familiarity but do not prescribe a Java course, so treat this as a practical starting checklist rather than an official prerequisite list.
- Use variables to keep track of values such as position, speed, and score.
- Use conditionals and loops to make decisions and repeat game updates.
- Understand methods, fields, and classes so you can follow how game behavior is organized.
- Learn basic collections when you need to manage groups of objects.
Choose a framework and keep the first target simple
For a code-first Java game, libGDX is the best-supported starting route here: its project provides an official setup guide and staged game tutorials. The project describes libGDX as a Java framework based on OpenGL ES, with listed targets including Windows, Linux, macOS, Android, browser, and iOS. Those targets do not mean a first project runs everywhere without additional setup.
JavaFX has a different stated role. Oracle’s JavaFX getting-started documentation presents it as a framework for desktop applications. It may suit a desktop graphics or application project, but the available official documentation does not establish it as an equivalent multi-platform game-development workflow.
| Option | Best fit | What it offers | What to keep in mind |
|---|---|---|---|
| libGDX | A first structured, code-first Java game | Official setup instructions and a staged game tutorial; the project lists desktop, mobile, and browser targets. | You will work with Java and Gradle setup. Start with desktop; additional targets add platform-specific concerns. |
| JavaFX | A Java desktop application or graphics project | Official getting-started documentation for desktop applications. | The cited documentation does not describe the same game-oriented, multi-platform tutorial path as libGDX. |
Set up libGDX for a desktop first game
Follow the official libGDX setup guide and choose an IDE based on your intended targets. The guide recommends Android Studio for newcomers who want to work toward desktop and mobile; it also lists IntelliJ IDEA and Eclipse. For the IntelliJ IDEA and Eclipse setup paths, it specifies JDK 17 or 21. Follow the current instructions for your chosen IDE and JDK, since tool support can change.
- Install an IDE and Java development setup using the current instructions for that IDE.
- Use the official project generator described in the setup guide.
- For the first milestone, select the core and desktop modules. Do not add mobile or browser targets yet.
- Use the suggested ApplicationListener template and confirm the generated desktop project runs before adding game features.
The tutorial explains that adding other platforms at this early stage can introduce issues a beginner may not yet be ready to solve. A desktop-only milestone keeps the first task focused on learning the game loop rather than debugging multiple target configurations.
Build the small game before expanding it
Follow libGDX’s A Simple Game tutorial. Its example is a bucket that catches falling droplets. The tutorial introduces assets, application lifecycle, rendering, input, game logic, and audio in sequence. In its example, the render flow separates input handling, logic updates, and drawing—an approachable way to see how a game responds and changes over time.
Keep the first build close to that scope. Resist starting with a large RPG, multiplayer game, or elaborate world: those ideas add systems before you have a working loop. First make the example playable, then change one thing at a time, such as adding a score, restart behavior, a second screen, or another obstacle. Run the game after each change so a new feature does not obscure a break in something that already worked.

The simple game tutorial intentionally keeps its implementation in one class for clarity and notes that this sacrifices good organization. Once the game works, move on to Extending the Simple Game, which continues toward screens and improved structure. The libGDX learning sequence recommends setup, then the simple game, then the extension. It also links a simpler alternative for readers who are entirely new to game development.
Keep the learning sequence practical: understand where assets load, where input is handled, where game state changes, and where drawing happens. As the project grows, use the extension tutorial to improve its organization rather than trying to design a large architecture before you have a playable game.

There is no controlled comparison here that proves one IDE is easiest. Use the intended target to narrow the choice: Android Studio is the setup guide’s recommendation for newcomers aiming at desktop and mobile; IntelliJ IDEA and Eclipse are also listed. Follow the IDE-specific setup steps and JDK requirement on the official page rather than mixing instructions from different setup paths.
For a computer, the supplied official setup and tutorial pages do not establish a specific hardware requirement or price threshold. Check the current setup instructions and your chosen IDE’s own requirements instead of buying a machine based on an unsupported minimum.

How current is the libGDX route?
The libGDX project’s homepage reported releases 1.14.1 and 1.14.2 on May 28, 2026. Use the setup guide and tutorial pages for the actual steps, and check the project’s news page for later release information before starting, because versions and setup guidance can change.
