The AnyRPG Core package is available via github and the Unity Asset Store. This page describes how to install it from github.
Install the Correct Unity Version
The AnyRPG Unity package is exported as a complete project because it requires specific build settings, compiler settings, layers, and tags to function. Due to the way full projects are exported in Unity, they must be imported with the same Unity version they were exported with.
Choose one of the download methods that Github offers.
For example, you can clone the project into a directory on your computer if you have the git CLI installed using the command git clone [email protected]:AnyRPG/AnyRPGCore.git
Open Unity Hub and Add the Project
Open Unity Hub and select the Projects tab. Click Open > Add Project From Disk.
Find the project folder and choose Add Project.
Open The Project
The project should now be visible in Unity Hub. Click on it to open it.
When presented with the option, choose Ignore. This is necessary because AnyRPG relies on UMA and it's not included in the github project.
Once the project opens, you will see errors in the console. These will be fixed in the next step by installing UMA.
