SHANEE NISHRY: Making virtual reality games

In this video I'll go over the concepts and implementation

of adding Cardboard support to a Unity project.

with an editor that allows you to easily import 3-D models

Before we start, make sure to get the Cardboard Unity

Then, open your Unity project and import a package like this.

Now that they are all set, there are two things you need to do.

and make sure your user interface works well

Let's start with adding the camera and look into modifying

You can do so by using one of the available prefabbed objects

or by attaching a script to an existing camera.

The easiest way is to use the Cardboard main prefab.

This is best if you're starting a new project

or haven't made any changes to your existing camera.

Simply replace the existing camera with the Cardboard

You can still add any custom scripts on top,

Press Play, and you'll have a functioning scopic view.

You can rotate the camera using the Alt key

To simulate Cardboard Trego, press the left mouse button.

Add it as a child of your camera and select

Update Stereo Cameras from the Components menu.

a functioning stereoscopic view in the game window.

By adding the stereo controller script to your camera,

two stereoscopic cameras will be created dynamically

You may not want to use the stereo controller script

since it doesn't let you add any image processing on top

of the cameras because they are added dynamically.

If you want to create the cameras in the Editor,

then simply select Update Stereo Cameras from the menu

Last thing we have to do is get the user interface working

Start by adding the [INAUDIBLE] Input Module script

This script emits [INAUDIBLE] for the event system

Next, in your UI element, set the Conference Render mode

to [INAUDIBLE] Space and set the event camera

to a camera controlled by a Cardboard head script,

At this point, the system is able to respond to the user's

gaze into triggers so that UI elements, such as buttons,

If you wish to interact with 3-D objects in the scene,

add a physics ray caster component to the event camera.

Designate an in-game object to be interactive

by adding a collider component to interact with the ray

or you can implement some of the standard Unity event interfaces

If you wish to add a cursor to let a user see

the point of their gaze, set the Gaze Input models cursor

to the game object that will serve [INAUDIBLE].

This cursor will be moved to the exact point on whatever UI

If the event camera has a physics ray caster,

then this includes 3-D objects with the collider components.

If no object is hit by a ray cast, the cursor is hidden.

Now that you know how to make everything work,

it is important to keep in mind some best practices in order

to make a compelling virtual reality experience.

The three most important words to remember

are always keep tracking on, keep stable 60 frames

per second or higher, and avoid unexpected motion.

One of the things that makes virtual reality compelling

In contrast, it would feel extremely unnatural

if the camera stopped responding to your head.

Therefore, you should always take into account

the user's orientation and never freeze the camera

or force the user to look somewhere specific.

If you want to grab the user's attention,

use cues such as light and sound to direct

You can also delay activating an event in your scene

That way, they have time to take things in and enjoy the scene.
