Building a 3D Game with LibGDX

Overview of this book

LibGDX is a hugely popular open source, cross-platform, Java-based game development framework built for the demands of cross-platform game development. This book will teach readers how the LibGDX framework uses its 3D rendering API with the OpenGL wrapper, in combination with Bullet Physics, 3D Particles, and Shaders to develop and deploy a game application to different platforms You will start off with the basic Intellij environment, workflow and set up a LibGDX project with necessary APIs for 3D development. You will then go through LibGDX’s 3D rendering API main features and talk about the camera used for 3D. Our next step is to put everything together to build a basic 3D game with Shapes, including basic gameplay mechanics and basic UI. Next you will go through modeling, rigging, and animation in Blender. We will then talk about refining mechanics, new input implementations, implementing enemy 3D models, mechanics, and gameplay balancing. The later part of this title will help you to manage secondary resources like audio, music and add 3D particles in the game to make the game more realistic. You will finally test and deploy the app on a multitude of different platforms, ready to start developing your own titles how you want!

Importing the model, finally!


We can finally render the model after performing the following operations on it:

  • Modeling

  • Rigging

  • Animating

  • Giving the animation a name

  • Getting the texture UV maps

  • Texturing or painting (based on your preference and/or needs)

  • Exporting

  • Converting the file to a format

What we do here is, first, copy the converted file along with the texture file to our assets folder. For us, it is Assets | Data from our Android project:

We'll then clean up and add the respective code to GameWold.java:

public class GameWorld { 
   private static final boolean debug = false; 
   private DebugDrawer debugDrawer; 
   private Engine engine; 
   private Entity character, gun; 
   public BulletSystem bulletSystem; 
   public ModelBuilder modelBuilder = new ModelBuilder(); 
   public PlayerSystem playerSystem; 
   private RenderSystem renderSystem; 
   Model wallHorizontal = modelBuilder.createBox(40, 20, 1, 
           new Material(ColorAttribute...
