The Beginner’s Guide to VR development with unity

Getting started is one of the first steps anyone takes while starting to learn anything, and it is a very crucial step. In this article, we will be starting from the basics. We will be exploring the different things related to VR development with Unity.

There are many devices for which we need to develop VR Applications, like – Oculus Quest 2, Oculus Rift, HTC Vive, etc. In This VR development unity blog series, we will be using the Oculus Quest 2.

We have game development engines such as Unity, Unreal, Godot, Panda3D, etc. There are many more engines, but these are popular VR game development engines.

We will talk about these VR game development engines in different blogs. 

We will be using the Unity Engine in this series. Unity uses the C# language for developing the business logic of the game, and Unreal Engine uses C++. 

Most of the games in the industry are made with the Unity Engine; Now, many game engines are trying to compete with Unity. 

We will use Unity as it has a significant Market share hence a big developer community. So it is advantageous for any indie developer or Game Development Firm to work with Unity. 

Installation of Required Software for unity vr development

We must install the Unity software to start the game development in Unity. 

There are two software you need to download Unity & Unity Hub.

Unity is a game engine that provides all the required tools to create 2D, 3D, or VR games. It consists powerful editor, a scripting language (C# or UnityScript), a physics and audio engine, and a range of other features for creating games and applications.

Unity Hub is a utility that manages all the projects, unity version installation & launching, essential add-ons, and other learning stuff in a single place.

Firstly, follow these steps to download and set up the environment.

Go to unity.com/download

Download the Unity Hub and setup,
Run the application & Make sure you agree with the terms and conditions

Select the location where you want to download the Unity Hub, and That’s it!

Sign In to Unity as a Personal Account (it provides you with the accessibility to use the features)

Now you need to download the Unity Engine. To download the Unity Version, use the LTS (Long Term Support) version. Because the LTS version will be stable, the company will keep on enhancing the functionality of these versions.

Click on “Install Unity Editor”, and you will be redirected to this page.

Use the Personal Edition as it is a Free Edition, and you can use approximately all the functionalities of the Pro Version.

So After Installation, You are ready for game development in Unity; You can download as many versions on your device but keep only those that are required as these use a lot of memory in the device. So it is good practice to keep only those versions that are required. 

Now we will start the VR Development,

Setting up the VR Project 

So let’s start setting up the VR Project in Unity; we will use version(2021.3.6f1)  of Unity Editor.

Click on New Project, and You will be redirected to this screen, Select your version, choose which is colored or you can use as per your requirement, and change the Project name( I am using “Learn” as my project name, you can use your own), Now click on Create Project.

Now you are ready with the Game Development; We will understand the unity interface. 

Understanding The Unity Interface

When you click Create Project, you will be on the new page editor in some time. 

This page will look like this. 

This interface is called the Unity Interface. We will make you understand this interface step by step.

1. This Toolbar is used to access your Unity Account and Unity Cloud Services. It also has controls for Play mode; Unity Search; a layer visibility menu; and the Editor layout menu.

2. The Hierarchy window is a text-based hierarchical representation of every GameObject in the Scene. Every item which is in the scene window is present that is also present in the hierarchy, so these two windows are inherently linked.
   
3. The Game View presents how your final rendered game will be looking through your Scene Cameras. When you click the Play button, the simulation starts.
   
4. The Scene View provides the functionality to navigate and edit your Scene visually. This Scene view can display all 3D and 2D perspectives depending on the project type.
   
5. These overlays have the basic tools for manipulating the Scene view and the GameObjects. Add custom Overlays to improve your workflow.
   
6. The Inspector window can edit all the properties of the currently selected GameObject. As all different types of GameObjects have different properties, the layout and contents of the Inspector window depend on GameObject.
   
7. The Project window shows all libraries of Assets available to use in your Project. All the imported assets into your Project show up here.
   
   Check this URL for more details.
   
8. The status bar provides notifications of various Unity processes and quick access to the related tools and settings.
   

Certain popups contain important actions to perform 

When you click on the window tab in the top menu, you will have this very important and used wieldy pop. 

There are many Important Sections, such as Asset Store, Package Manager, General, Animation, Rendering, Audio, Sequencing, and many more. 

On Clicking Package Manager, you will see this window from where we manage all the packages. 

You can download new packages or assets.

For the movement of the GameObjects in the Unity Scene Editor, you can use an axis picker and move anywhere in the editor.
