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!

Modeling


Finally, we can move on to the most exciting part of the chapter, modeling:

  1. Select the Scale tool (explained in the basics).

  2. Make the cube wider on the y and z axis by clicking on the corresponding axis on the gizmo (one axis at a time).

  3. You can cancel any change on the model by right-clicking the mouse button or Ctrl + Z from the keyboard to undo, and Ctrl + Shift + Z to redo.

  4. Duplicate the cube by pressing Ctrl+C/ Ctrl+V on Object Mode or Shift+D on both Object Mode and Edit Mode, then scale it down and move it below the first one. This will be our grip.

  5. Now, just like we did with the body of the gun, scale the cube to make it thinner and taller.

  6. Select the first cube again (right-click over it).

  7. Now, let's add some resolution by splitting the vertical edges in half using the Loop Cut and Slice tool. To get access to that tool we need to change the mode to Edit Mode from the bottom bar:

  8. Now, by pressing Ctrl+R, we'll select Loop Cut and Slice. This will allow us to give the body...
