The Android Game Developer's Handbook

By: Avisekhar Roy

Overview of this book

Gaming in android is an already established market and growing each day. Previously games were made for specific platforms, but this is the time of cross platform gaming with social connectivity. It requires vision of polishing, design and must follow user behavior. This book would help developers to predict and create scopes of improvement according to user behavior. You will begin with the guidelines and rules of game development on the Android platform followed by a brief description about the current variants of Android devices available. Next you will walk through the various tools available to develop any Android games and learn how to choose the most appropriate tools for a specific purpose. You will then learn JAVA game coding standard and style upon the Android SDK. Later, you would focus on creation, maintenance of Game Loop using Android SDK, common mistakes in game development and the solutions to avoid them to improve performance. We will deep dive into Shaders and learn how to optimize memory and performance for an Android Game before moving on to another important topic, testing and debugging Android Games followed by an overview about Virtual Reality and how to integrate them into Android games. Want to program a different way? Inside you’ll also learn Android game Development using C++ and OpenGL. Finally you would walk through the required tools to polish and finalize the game and possible integration of any third party tools or SDKs in order to monetize your game when it’s one the market!

Use of shaders in games


Shaders are vastly used in games and animation, especially when creating dynamic lighting, changing tints, and making dynamic visual improvements. Sometimes, the world environment is created with shaders.

Shaders in a 2D game space

Only pixel shaders can be used in 2D games. Each pixel of a digital image is considered a fragment. This is the reason why pixel shaders are also called fragment shaders. Pixel shaders can only perform color changes, tiling, and masking.

BitmapShader, ComposeShader, LinearGradient, RadialGradient, and SweepGradient are the variants of Android 2D shaders.

A 2D game world is created with images. Developers often choose to create different assets to give the same object a different look and feel. In this process, developers end up making a bigger APK with almost the same use set.

Sprites can also be a field where shaders can hold a significant role. When using the same sprite to create different objects, the colors of certain fragments need to...
