Get the Unity SDK

The first step to use coherence in Unity is to install the coherence SDK.

Requirements

Latest Unity LTS releases are officially supported. As of now, we support:

• Unity 6 LTS (min. 6000.0.23f1)

• Unity 2022 LTS (min. 2022.2.5f1)

• Unity 2021 LTS (min. 2021.3.18f1)

From the Unity Asset Store

You can conveniently download the SDK from the Unity Asset Store:

​​​​

Alternative: From our package repository

As an alternative to the Asset Store download, you can manually install coherence from our package repository. The rest of this page describes the steps to do so.

Step by step process

1. Add the Scoped Registry

First, go to Edit > Project Settings. Under Package Manager, add a new Scoped Registry with the following information:

• Name: coherence

• URL: https://registry.npmjs.org

• Scope(s): io.coherence.sdk

Package Manager Advanced Settings

2. Install coherence

Now open Window > Package Manager. Select My Registries in the Packages dropdown.

Highlight the coherence package, and click Install.

Alternative: manually edit the manifest

As an alternative to the step-by-step process above, you can directly edit your package manifest.

Refer to Unity's instructions on modifying your project manifest.

• Edit 📂/Packages/manifest.json

  1. Add an entry for the coherence SDK under the dependencies object

  2. Add one for the scoped registry in the scopedRegistries array

You can see an example below:

{
  "dependencies": {
    "com.unity.collab-proxy": "1.3.9",
    "com.unity.ide.rider": "2.0.7",
    "com.unity.ide.visualstudio": "2.0.7",
    "com.unity.ide.vscode": "1.2.3",
    "com.unity.ugui": "1.0.0",
    /* Other packages... */

    /*** ADD THIS START ***/
    "io.coherence.sdk": "1.0.0",
    /*** ADD THIS END ***/
        
    "com.unity.modules.ai": "1.0.0",
    "com.unity.modules.androidjni": "1.0.0",
    "com.unity.modules.animation": "1.0.0",
    "com.unity.modules.audio": "1.0.0",
    "com.unity.modules.imgui": "1.0.0",
    /* Other modules... */
    
  }, /* < add this comma if not already present */
  
  /*** ADD THIS SECTION START ***/
  "scopedRegistries": [
    {
      "name": "coherence",
      "url": "https://registry.npmjs.org",
      "scopes": [
        "io.coherence.sdk"
      ]
    }
  ]
  /*** ADD THIS SECTION END ***/
  
}

You will then see the package in the Package Manager under My Registries.

When you successfully install the coherence SDK, after code compilation, you should see the Welcome window.
