Holistic Mobile Game Development with Unity Learning from

Introduction � � � Plethora of plug-in external modules or engines, including graphics systems, physics systems, artificial intelligences, mathematical systems, and audio systems. Unity’s inbuilt systems for movement, Navigation Meshes and Nav. Meshes, are grid-like systems sit over the top of existing terrain and game maps. These systems procedurally generate content. Extending these ideas to manipulate the physical game environment at runtime, makes a game build and extend on itself. Extends gameplay and the size of a game level without the need for gigantic game maps. @ 2015 Taylor & Francis. All rights Reserved. 2

Learning from the Masters: Part Two Summary The use of the physics engine, procedural algorithms, and artificial intelligence for creating dynamic behavior within the game environment and in characters. � The functionality of the game engine isn’t just there to carry out precise commands. � Interesting, challenging, and engaging game mechanics can result from letting the code do it for you. � @ 2015 Taylor & Francis.
