Update
The Inworld Unity SDK version 3.3 is not compatible with previous versions. If you wish to upgrade your Unity SDK, uou must first delete the Assets/Inworld or Assets/Inworld.AI folder.
The APIs for Unity are not identical. See below for guidance on how to upgrade to the latest SDK:
- If you are using version 2.X, refer to this Upgrade Manual.
- If you are using versions from 3.0 to 3.2, refer to this Upgrade Manual.
Supported Unity Versions
Inworld's Unity SDK supports up to Unity 6.
The minimum supported Unity version is 2020.3.48f1. Any version below this may not be compatible.
MacOS Version
If you are using MacOS and want to build MacOS applications, there is a known bug for Unity.
To avoid this, it is recommended you upgrade to 2022.3.10f1 or newer.
Unity SDK Developments
Support for Inworld Unity SDK v3.3 NDK has ended. Going forward, Inworld's focus has shifted exclusively to the Websocket client.
While the NDK offers a noticeable advantage in terms of package size, the performance speed between Websocket and NDK is comparable. However, the user base for Websocket significantly exceeds that of the NDK. Considering the substantial effort required to maintain both systems with future updates, Inworld has deprecated the NDK client.
From Inworld Unity SDK v3.2. we offered two different Unity SDK versions: full package InworldAI.Full and core package inworld-unity-core. We have separated the various modules using Unity's Assembly Definitions.
inworld-unity-core supports lightweight projects with a significantly smaller download size (less than 1 megabyte). It does not include any character models from ReadyPlayerMe or Inworld avatars, which is suitable for developers with capabilities to import their own character skeletons and animations in Unity. Ideal for WebGL deployments or projects where package size is a consideration.
⚠️ Note: inworld-unity-core is provided as a Package, catering to core functionalities, whereas InworldAI.Full, offered as a Unitypackage, encompasses the entire suite of features and assets, and includes a reference to inworld-unity-core for foundational capabilities.
