VR in Unity Projects

You can enable the VR support in unity through the following steps:

1. Go to edit
2. Then project settings
3. Then player
4. Then other settings
5. Then rendering.
6. Lastly checking the “Virtual Reality Supported” checkbox.

Following are the visuals provided for better understanding.

VR Preview in Unity

After you have enabled the VR support in Unity editor, the game view will be displayed on the DK2 and editor once you enter the play mode.

The good thing is that you don’t have to make a separate executable file to see the changes in VR, enabling you to make easier changes and iterations.

Getting Started

Once your hardware and software is up to the requirements, make sure that you have connected the Oculus development kit 2 before opening the Unity.

As you have set up everything, we will now dive into the virtual reality tutorial that is a pathway to making virtual worlds and virtual reality applications.

VR Basic Project

We will start the basics by creating a test project in Unity. It will be a cube which we can observe in VR.

Step 1

When you start the Unity for the first time, create a new empty project from the Unity home screen.

Step 2

From the top menu

1. Go to File
2. Select build settings.

Now a window will pop up. Ensure that you have selected the PC, Mac & Linux Standalone in the platform tab.

Following is a visualization provided for better understanding.

Step 3

Create a new cube by the following procedure

1. Go to game object.
2. 3D object
3. Cube

Now you can see a cube, using the Translate tool, move it to position in front of the main camera by default.

Following is a visual showing the cube.

Step 4

Save the scene you just made as

1. Go to file
2. Save scene

Step 5

Skip this step if you have already enabled the “virtual reality supported” option.

1. Go to edit
2. Then project settings
3. Then player
4. Then other settings
5. Then rendering.
6. Lastly checking the “Virtual Reality Supported” checkbox.

Step 6

At the top, click on play to enter the play mode.

Yes, we are ready to see the first project in Development Kit 2.  You can see now using your DK2, with one camera on game view. Camera in Unity will show the changes in position and rotation of DK2 if you look around the scenes.

VR Projects

Various sample VR projects are available on the Asset store. These sample projects are compatible with Oculus Development Kit 2.They will help you to understand the development of virtual world. Moreover, they are free of cost.

Sample Scenes

The sample scenes are:

• Intro: An Introduction scene to introduce the user to the basic interactions
• Menu: A Menu scene to choose a mini game to play
• Flyer: An into-the-screen flying game
• Maze: A table-top maze game
• Target Gallery: A corridor target shooting gallery
• Target Arena: A 360° shooting arena
