Submit your final project

Learn to write scripts for advanced interactions in VR applications, and create your own unique VR project.

In the previous missions, you used pre-made interaction scripts provided to you as part of the Create with VR project. This mission will teach you to write scripts specifically for VR applications. You’ll write these scripts from scratch in the context of three separate projects.

In project 1, the XRI example scene created by the XR Interaction Toolkit team, you'll reference existing code and documentation to program some more advanced, customized interactables.

In project 2, you’ll follow guidelines from a project brief to create part of a VR escape room. Rather than following step-by-step instructions here, you’ll only receive hints.

In project 3, which you’ll submit to receive your pathway badge, you’ll create your own unique VR project. The challenge here is to create a clone with a twist: a version of an established VR experience, but with a unique alteration.

, you should already have a good foundational knowledge of scripting in the Unity engine to make the most out of this learning content.

If you don’t already have a foundational understanding of scripting, now is an excellent time to learn. We recommend you complete the

In this challenge, you'll apply the skills you learned while making your VR Room in a 3D painting app. In this app, the user can choose the shape they want to paint on, select the color and size of their brush on a handheld palette, and then create their masterpiece!

This challenge will review your skills learned in the following lessons:

Unit 3: VR Events and Interactions

1.  Open the broken 3D painting prototype Scene:

From the Project window, expand, Assets > Challenges > 02_3DPainting > Scenes

Double-click on the 3DPainting_Prototype_Broken Scene to open it.


2.  Begin working on the challenge tasks:

Work through the tasks outlined in the steps below.

If you want to push your skills, attempt the optional bonus challenge tasks, as well.

If you get stuck, there are hints for each task at the bottom of the page.


1.  The Canvas that allows you to change the shape on the pedestal follows the camera.

This canvas should be stationary next to the pedestal. 


2.  The toggled ray and palette canvas are tracking the opposite hands.

The palette should move with the left hand and, when you press the thumbstick or primary button on the right controller, the toggled ray should emit from the right hand.


3.  The paint brush activation is backwards, starting when the trigger is released and stopping when it’s pressed. 

The paintbrush should create a trail while the trigger is being held, stopping when the trigger is released. 


4.  The medium brush size button turns invisible when pressed and makes the trail gigantic.

The button should turn the same grey color as the other buttons when pressed and change the trail to a size in between the small and large brush sizes.


5.  The paint brush sound effect stays the same, regardless of how far it is from you.

The paint brush sound should be at full volume close to your face, but about 50% volume when your arm is outstretched

6.  There is no audio feedback from the UI.

Add sound effects for all of the buttons in the UI and a continuous sound effect that plays while the paint brush is in use.


7.  There is no way to hide the pedestal completely.

Add a toggle UI to the menu next to the pedestal that shows/hides the pedestal object when toggled on/off.

Add a “Print” button that creates a miniature version of your 3d creation on a table next to you.


9.  There is no way to paint on the back or sides of the object.

Add a slider to the UI that rotates the entire pedestal, giving you the ability to paint the back as well.

1.  The canvas render mode needs to be in “World Space” - not “Screen Space”.

2. Look at the input mapping in the XR Controller components for the LeftHand and the RightRay.

3.  Look at the functions in the Activated and Deactivated events in the paintbrush’s XR Grab Interactable component.

4.  Make sure to check the alpha (transparency) value of the button tint. Look at the functions on the small and large brushes for references on the ideal trail width. 

5.  Make sure that 3D audio is enabled, and check the 3D audio rolloff curve to make sure it is down to 50% at around 1 meter from the source.
