VR Events & Interactions

Unit 3: VR Events and Interactions

Events and Interactions

Up to this point, you have only been able to pick up and put down objects. Now, you will add an object that you can do something with - or “activate” - once it’s in your hand.

Go to Course Library > Prefabs > Objects > Electronics, 

Drag the “Remote” prefab object onto a surface in your scene.

Add a Rigidbody component with Collision Detection set to Continuous Dynamic so it doesn’t fall through the floor.


3.  Position the remote correctly in the player’s hand when it is picked up:

In the Remote object, create a new, empty “Attach” child object.

Position and orient the Attach object appropriately.

Assign the Attach object to the Attach Transform property in the XR Grab Interactable component.

You should now be able to pick up the remote in a way that looks natural.

In the Hierarchy, an Attach GameObject is highlighted, which is a child of the Remote GameObject. In the XR Grab Interactable component, the Attach Transform property is set to that Attach child object.

Now you will make the remote make a click sound when you are holding it and press the trigger.

On the Remote object, add an AudioSource component 

In the AudioSource component, slide the Spatial Blend property all the way to full 3D (“1”) to allow for 3D audio.


2.  Give the remote the ability to play a sound:

Add a Play Quick Sound component to the remote.

For the Sound property, assign an audio clip you want from the Course Library > Audio folder.


3.  Locate the remote’s “Activated” event:

At the bottom of the remote’s XR Grab Interactable component, expand the Interactable Events fold-out to see all of the event options.


4.  Play a sound when the remote is activated:

In the Activated event, click the + to add a new action. 

Drag and drop the Remote object to the empty Object slot in order to access its components.

Click the No Function drop-down to select a function, then select Play Quick Sound > Play (). 

Note: In the updated version of the component, Activate is now called On Activate. 

With the remote in your hand, you should now be able to press the activate button, the controller trigger, and hear a sound. 

In the On Activated event, the Remote object is assigned to the GameObject property. The Function drop-down is set to PlayQuickSound.Play.

To provide additional feedback that the remote has been pressed, you can also turn the indicator light red when the remote is activated.

1.  Add the capability for the indicator light to turn red:

In the Hierarchy, expand the Remote object and select the Indicator_Light child object. 

Assign a Red material to the “Other Material” property. 


2.  Change the material color to red when the trigger is pressed:

On the Remote parent object, at the bottom of the XR Grab Interactable component, expand the Interactable Events fold-out to see all of the event options.

In the Activated event, click the + to add a new function. 

Assign the Indicator Light child object to the Object property.

Click the No Function drop-down to select a new function, then click Change Material > SetOtherMaterial () function. 


3.  Make the material revert when the activate button is released:

In the Deactivated event, click the + to add a new action. 

Assign the Indicator_Light object, then select the Change Material > SetOriginalMaterial () function.

Note: In the updated version of the component, Deactivate is now called On Deactivate.

When you activate the remote, the indicator light should turn red and then revert to its original color when the activate button is released.

In the On Activated event, the Indicator_Light object is assigned to the GameObject property, with the Function drop-down set to ChangeMaterial.SetOtherMaterial. In the On Deactivated event, the Indicator_Light object is assigned to the GameObject property, with the Function drop-down set to ChangeMaterial.SetOriginalMaterial. 

Before you get the button set up to turn the TV on, you should make sure the TV in the scene can successfully play video. 

In the Hierarchy, select the Screen child object of the Television.

Drag the Spatial Blend property to full 3D (1.0) to enable spatial audio.

On the Screen child object, add a Video Player component. 

Change the Material Property to _BaseMap (instead of _MainTex) to project the video to its material rather than its texture.  Note: You may have to disable Auto-Select Property before you can change the Material Property as shown in the video. 


3.  Add additional video control functionality:

On the Screen child object, add a Play Video component. 

Select the Play At Start check box to play the video automatically.


4.  Select the video to play on the screen: 

In the Play Video component, expand the Video Clips fold-out.

Set the list Size property to 1 and press Enter to reveal an empty Video Clip slot.

Assign one of the videos from the Course Library > Videos to the Video Clip property.

Now when you run your application, the video should play automatically on the TV Screen with 3D audio.

In the Video Player Component, the Material Property is set to _BaseMap. The AudioSource component is also highlighted. In the PlayVideo component, the Play At Start property is enabled and, in the Video Clips drop-down, the Unity-for-everyone video is assigned.

Now that the TV is working, you need to be able to control it with the remote. 

1.  Stop the video from playing automatically:

In the Play Video component, clear the Play At Start check box.


2.  Locate the Remote’s Interaction events:

In the XR Grab Interactable component, expand the Interactable Events fold-out to see all of the event options.


3.  Trigger the TV when the remote is activated:

In the Activated event, click the + to add a new action.

Assign the Screen object to the empty Object property, since it has the Play Video script. 

Click the No Function drop-down and select the PlayVideo > TogglePlayPause () function, or the PlayVideo > TogglePlayStop () function, depending on whether you want it to pause or stop when pressed a second time.

When you activate the remote, the video on the TV should alternate between playing and pausing or stopping.

In the On Activated event, the Screen child object of the TV GameObject is assigned to the GameObject property, with the Function drop-down set to PlayVideo.TogglePlayPause.


If you want to further develop your skills, explore new concepts, and improve your project, check out some of the optional extension activities below. 

Each one is tagged as [Easy], [Medium], [Difficult], or [Expert] and will also include a [Requires Programming] tag if some coding is required. 

Make a phone that plays a video when you press the trigger:

You can find phone prefabs from the Course Library > Prefabs > Objects > Electronics folder.

You will need to make a new separate “screen” child object with a material similar to the way the TV screen is set up.

Bonus:  Try making the phone cycle through multiple videos using the Play Video > NextClip () function. 

2.  Add a functioning flashlight [Medium]

Add a working flashlight into the scene that toggles on and off when you press the trigger, including making a clicking sound to provide audio feedback:

You will need to add a child SpotLight object to the flashlight.

Try using the ToggleLight > Flip () function to flip the light on and off. 

3.  Add a functional lighter and candle that can be lit with it [Difficult]

Add a lighter to the scene that produces a flame when you activate it. If the flame gets close to a candle, that candle can be lit. 

On the candle, use a trigger collider and the OnTrigger script to detect when an object with a particular tag has entered the trigger

Bonus:  Make the flame go out when it is shaken using the OnVelocity script

4.  Add a dart gun or stapler projectile [Expert]

Add a dart gun that shoots darts or a stapler that shoots staples when you press the trigger:

Locate the prefabs for the objects and projectiles in the Course Library > Prefabs > Objects > Launchers folders

Use the LaunchProjectile script provided in the Course Library

If you want, use the DestroyObject script provided in the Course Library to make the projectile disappear after a certain amount of time.

Bonus:  Make the stapler swing open with a hinge joint

Bonus:  Add sounds for when the object is launched

5.  Add a functioning polaroid camera  [Expert] [Requires Programming]

Add a functioning polaroid camera that allows you to preview on a viewfinder screen and print a photo using the trigger:

For the viewfinder screen, look at how the mirror is set up with a render texture.

Look at the documentation for Camera.Render(). 

Don’t worry if the camera is currently rendering your rays for now - we’ll learn how to hide your rays in the next tutorial.
