Install instructions

Our plugin works best with Unity version 2021.3.28f1 and higher. It will still work with earlier version of 2021.3.x, see "Version Compatability" section below.

1. Download plugin

Plugin-only (best for integrating w/ existing game): Hathora_Cloud_Unity_pluginonly_latest.unitypackage

Plugin + demo (best for learning): Hathora_Cloud_Unity_plugin_latest.unitypackage

2. Open the Unity project you want to add the plugin to

3. Add Hathora_Cloud_Unity_plugin_latest.unitypackage as a "Custom Package" (Assets > Import Package > Custom Package..)

NOTE: If you're installing the plugin-only version, you may notice errors with The type of namespace name "Newtonsoft" cannot be found. These are expected, to fix you will need to install Newtonsoft via Unity's Package Manager. You can do so by adding the package by name: com.unity.nuget.newtonsoft-json.

4. Using the "Hathora" top menu item, create a new config file

5. Create or login to your Hathora Cloud account using the Editor inspector on your newly created config file from the previous step

6. Create an application in Hathora Cloud

7. Now you can use the plugin to build and deploy your game server.

Version compatibility

Our plugin works best with Unity version 2021.3.28f1 or higher.

It does still work for earlier versions of 2021.3.x, but you will need to fix the Universal Render Pipeline (URP) package version. Note that URP is only used for our included demos, so if you simply ignore/delete the Demo folder, you can ignore the URP dependency.

1. Window > Package Manager > remove Universal RP
2. Find package via Unity Registry > install Universal RP (should be version compatible with your Unity version)
3. Edit > Project Settings > Graphics > set "Scriptable Render Pipeline Settings" to StarterAssetsURP
