Getting Started

We suggest that you start by reviewing the sample scenes provided in our Unity Integration package before incorporating your own scene. This will help ensure a smooth integration process.

Here's a useful walkthrough of the demo scenes that are included with our Unity V3 SDK.

1. Importing the Package

There are three ways you can import the Inworld AI Unity SDK unitypackage into your scene:

  1. Open Unity and go to Assets > Import Package > Custom Package. Next, select the unitypackage that you downloaded.
  2. Drag the unitypackage that you downloaded into Unity's Project panel.
  3. If you only have one instance of Unity running, then double-click the downloaded unitypackage.

When the Import Unity Package box appears, click the Import button:


⚠️ Note: It is recommended to delete the Inworld folder from your Asset folder if you have previously used an old version of the Inworld AI Unity SDK before importing the new package as it may not be compatible.

Based on the Unity package (Lite vs Full) you have downloaded, we have prepared different basic demos to help you get started.

2. InworldAI.Lite

Sample 2D Scene

In Assets > Inworld > Inworld.Assets > Scenes, you will find a sample scene Sample2D. You can interact with the character Innequin by 2D chat panel.

This sample scene is also included in InworldAI.Lite, only this sample is accessible.

⚠️ Note: By default, the contents under Packages in a Unity project are read-only. If your project references InworldAI.Lite solely through the Package Manager, please copy the Packages/Inworld.AI/Runtime/Scenes/Sample2D.unity to your Assets folder.

Import Text Mesh Pro

The Inworld AI Unity SDK requires "Text Mesh Pro", which is included with Unity but not imported by default. If you are opening any Unity scene inside Inworld Unity package, or opening the Inworld Studio Panel for the first time, please click Import in the dialog for "Text Mesh Pro" if it appears.

Typing to the character

You can type sentences, and press the "Enter" or Send button, to send a message to the character.


Speech to Text

Alternatively, you can hold down the Record button, speak your message, and then release Record to send a voice message.

⚠️ Note: If you are building a WebGL application, the microphone is not supported, so the Push-to-talk feature is not available either.


3. InworldAI.Full

Innequin Sample Scene

In Assets > Inworld > Inworld.Samples.Innequin > Scenes, you will find the 3D Innequin sample scene. This shows how Innequin is set-up with an InworldCharacter component, animation controller, and animations, as well as lipsync.

Talking to the Character

After pressing the Play button, please wait until the Inworld server has been connected. The avatar Innequin will wave at you, and then you can start speaking to the character.


⚠️ Note: If you change your audio input (i.e swap microphone input) during runtime, the new voice will not be recognized until you restart the app or re-enter Play Mode. Restarting the app will cause the change to take effect.

Typing to the Character

Press the ~ button to open or close the text input panel during runtime. While the text input panel is open, you can type sentences to the character.


Speech to Text

While the text input panel is open, you can hold the Record button to record your sentences using your microphone. Release the button to send the recorded message.
