In this Code Pattern we will create a Virtual Reality game based on Watson's Speech-to-Text and Watson's Assistant services.
In Virtual Reality, where you truly “inhabit” the space, speech can feel like a more natural interface than other methods. Providing speech controls allows developers to create more immersive experiences. The HTC Vive is the 3rd most popular head-mounted VR devices (not including Google Cardboard) and an ideal candidate for Speech interaction, selling roughly 400 thousand units in 2016.

.Note: If you are in any IBM Cloud region other than US-South you must use Unity 2018.2 or higher. This is because Unity 2018.2 or higher is needed for TLS 1.2, which is the only TLS version available in all regions other than US-South.
git clone https://github.com/watson-developer-cloud/unity-sdk.git
Make sure you are on the develop branch.
Open Unity and inside the project launcher select the button.
Navigate to where you cloned this repository and open the Creation Sandbox
directory.
If prompted to upgrade the project to a newer Unity version, do so.
Follow these instructions to add the Watson Unity SDK downloaded in step 1 to the project.
Follow these instructions to create your Speech To Text and Watson Assistant services and find their credentials (using IBM Cloud
You can find your workspace ID by selecting the expansion menu on your assistant workspace and selecting View details
.
In the Unity Hierarchy view, click on _Scenes
->MainGame
->MainMenu
and then the SaveCredentials
object.
In the Inspector you will see Variables for Speech To Text
and Watson Assistant
and either CF Authentication
for the Cloud Foundry username and password, or the IAM Authentication
if you have the IAM apikey. Since you only have only one version of these credentials, fill out only one of the two for each service.
Fill out the Speech To Text Service Url
, the Assistant Service Url
, the Assistant Workspace Id
, and the Assistant Version Date
. There are tool tips which will show help and any defaults.
