Pong game (prototype) In this article, we recreate the two-player game Pong – the first arcade video game 1972 – for Android using Kotlin. We will implement the game SurfaceView, game loop design pattern, and code optimization for better performance. Game loop Game loop is a common design pattern in game development. It is already integrated into different game engines. Nevertheless...
This article demonstrates the collision between square, circle, and points using Android Kotlin. We will focus on the programming aspect rather than using complicated mathematical equations. A video tutorial is at the end of the article. Two rectangle collision Using complicated math for rectangle collision is not always necessary. Java and Kotlin offer a convenient way to detect the collision...
