Hey there! Welcome to the latest episode of 3D Game Programming in Java. Today, I want to show you a neat trick that will make your game development process even smoother. We will talk about how to export your project as a runnable file, allowing you to run it on any computer without needing to have your code and Eclipse open. Let’s dive in!

Exporting your game as a runnable jar file
To begin, open your project in Eclipse and follow these easy steps:
- Click on File and select Export.
- In the dialog box, expand the Java folder and choose Runnable JAR File. Click Next.
- Now, select the Launch Configuration to use. If you haven’t created one yet, you can go ahead and do that. Name it something meaningful. For example, you can use “MyGameAlpha”.
- Make sure to select the project that you want to export from the drop-down menu.
- Check the option to Extract required libraries into generated JAR. This ensures that all the necessary libraries are included in the file.
- Finally, click Finish to complete the export process.
Troubleshooting
In some cases, you might encounter an error message saying that the jar creation failed. Don’t worry; this is a common occurrence. Here’s how you can resolve it:
- If the error occurs, click Cancel to close the dialog box.
- Right-click on your project and select Refresh to sync the resources with the file system.
- Repeat the exporting process following the steps mentioned earlier.
Testing your game on different systems
Once you have successfully exported your game as a runnable jar file, you can now test it on various computers. This is particularly useful since you don’t know which system your players will be using. Here’s a quick demonstration:
- On your computer, right-click on the jar file.
- If it opens with WinRAR by default, select Open with and choose the Java platform instead.
- Your game should now open in its own little window, ready to be played.
Feel free to test your game on different systems, such as Windows, Mac, or Linux. This will ensure that your game runs smoothly for all your players, regardless of their operating system.
