Unity’s Touch system for mobile development can monitor several properties of touches, allowing a wide variety of control systems for both games and applications. Touches are tracked individually, each associated with the finger that made it, and carry with them several data elements. In this tutorial, you will learn about Unity's Touch system and how to use it in mobile development.

Lean Touch is an asset available in the Unity Asset Store that makes scaling and rotating objects in AR easy. In this tutorial, we’ll apply the Lean Touch script. We assume that you’re starting this tutorial with an open project that places or loads objects into an AR scene.

Trash Dash is a game that Unity created as an example of how to use Unity Services in a mobile game. It also contains some useful examples of coding architecture and techniques for solving common game programming problems. In this tutorial we'll take a quick tour of the code for Trash Dash and learn about these features.

In this intermediate course, participants will learn how to produce performance-optimized 3D assets and scenes for mobile applications. Topics will cover tips on optimizing Geometry, Textures, Materials, Shaders, and Lighting. This course was created with technical artists and content creators in mind.

Publishing for Android is a lot like publishing a build for Windows, Mac OS, and Linux. In certain cases, there are no required changes at all. For example, in a mobile game that uses finger gestures to interact with game elements, this can be accomplished with the same code as its desktop counterpart. Mobile touch input is beyond the scope of this workflow, so it’s assumed that the game is complete and ready for distribution.

Optimization is a broad topic and how you optimize depends heavily on your specific project. This tutorial should be read as an introduction to optimization tips and suggestions rather than a step-by-step guide that guarantees optimized particle effects for your mobile projects. The process of optimizing particle effects for mobile devices can change depending on the project and can be a complicated task. In this tutorial, we will talk about common pitfalls and optimization considerations that will help you begin the process of optimizing your particle effects for mobile applications.

In this tutorial, we’ll learn how to use AR Session and AR Session Origin — both part of the Unity AR Foundation package — to place and manipulate objects in AR. If you haven’t installed the AR Foundation and AR package for your chosen mobile platform, please see Configuring Unity for XR Development.

In this tutorial, we’ll configure Unity for AR development targeting iOS or Android.

Instantiating objects, also known as spawning, and adjusting their positions are foundational features of interactive AR applications. Although these applications may serve different use cases with different visual styles, the logic behind object spawning is typically very consistent.
