Unity 3D Using VR Technology

As we know that virtual reality is the fastest-growing and most fascinating technology and some people even say that VR can be the future of the entertainment and gaming industry. For a long time, VR has been a dream for video game developers, despite disappointing games like Nintendo’s virtual boy. The objective of having fully-realistic VR game development can finally become reality after countless vaporware iterations.

VR has the power for transforming how we can generate things. It is far from perfect but hardware such as- Oculus Rift, PSVR, and the HTC Vive have made it far more tempting for consumers and developers alike.

Investing in VR now no longer needs thousands of dollars and state-of-the-art machinery. Nowadays, affordable software and VR headsets provide an opportunity for low-cost investment in Video game development. Do you want to learn how to make a Video game in Unity? You are in the right place. This blog will shed light on how to make a VR game in Unity and different game engines that can help you develop games. 

What is VR and How Is It Transforming the Gaming Industry?

Virtual reality is known as an immersive and realistic simulation of a 3D environment. VR gained essential ground in each scope due to the extension of digitization. It can increase business profits and can improve the consumer experience drastically. VR developers can now build VR solutions on par with industry veterans thanks to 3D game engines like Unity3D and Unreal Engine. 

Data

VR is getting famous in the gaming industry, and the industry is getting more and more benefits from this immersive technology. There are so many effective implementations of cutting-edge VR gaming in this industry.

Generate a Project

Open up Unity 3D to make a new project and you will be asked to download an asset. Download that environment package instantly. 

And once your project is open, go to Assets>Import package>Custom package >Import Google VR SDK for Unity>Import.

You need to create your project for the VR platform and you will be required to tell Unity you are making it for the Android platform and create the scene VR enabled. 

First, go to File>Build and then select Android. 

You can also easily select Landscape Left and then click the Switch Platform at the bottom and close the window. 

It is the right time to enable VR settings. And if you try to play the game before doing these above, you will have errors in your programs. 

So, Go to Edit>Project settings>Player, and after that, select on the right-hand side under XR settings, then click Virtual Reality supported. And, also choose SDK

Environment 

In starting, you should use GVR Demo Scene and open up your assets in the Project Lab, after going to scenes>GVRDemo. After opening the file, you will be changing the environment. You have to delete the following elements in the hierarchy- 

  • CubeRoom
  • Demo Scene Manger
  • Demo Input Manager
  • Cube
  • Floor Canvas

Keep everything else complete to develop games like pubg game development at GoogleSDK.

  • GvrControllerVisual offers visual feedback for the daydream controller.
  • GvrEditorEmulator offers mouse-controlled head-tracking imitation in the Unity editor.
  • GVR controller provides the keyboard Input to users.

Save your scenes and use GameObject for adding terrain. Select a grass surface in projects and drag it onto the scene. For adding some elements, add some hills. For the hierarchy that is under the terrain, select the button with the hill and the arrow will be pointed upwards. Now, select a brush, it will be good to alternate for making the environment look real. You can choose a smooth button for removing points at hills. For finding the right asset for your project, the Unity Asset Store is a great source for developers.

Get Move

Choose Players first and then add a component, after that capsule collider and Rigidboy. You also require to freeze the X and Y rotation of Rigidboy.

Beginner developers can also make a 3D game in Unity as it has imported libraries and a large volume of existing code. The same thing goes for video game engines but having a license to a whole video game engine would be very costly. So, the solution to this problem is the Unity 3D game engine which is free of cost and is used for making VR games in Unity with purchasable game assets and built-in libraries.

Now add the script to the player and save the file in the Unity folder and press and drag it into the project. 

After that, add a component>new script. Then type Autowalk and the script would show up. You may require to save your project and refresh it. And, after adding the script, you will have the option to configure it. Add a speed of 2 and check walk at the time of trigger

Game Testing

It’s time to test your developed game on the phone, the process is as follows-

File>Build Setting>Android>Build & Run. 

Then type an identifier and have an Android SDK that you can use freely. Save your game and transfer it to your phone by using a USB card and once the game starts, you may require to hit settings>cardboard, if it is off. In Unity, many objects will help you with Video game development and will provide you with better skills.
