New Entities project setup

With Unity 2022.2, create a new project from either an HDRP or URP template, then add the DOTS packages that you need by name from the package manager:

• com.unity.entities
• com.unity.entities.graphics (for rendering entities)
• com.unity.collections (unmanaged collection types)
• com.unity.physics (for collision detection and physical simulation of entities)
• com.havok.physics (alternative Havok-provided "backend" for physics)
• com.unity.netcode (for entities-driven server-client multiplayer)

These packages will include com.unity.burst and com.unity.mathematics as dependencies.

When working in an Entities project, you normally want these two settings:

• In the "Entities" section of the Unity preferences, set the "Scene View Mode" to "Runtime Data".
• In the "Editor" section of the project settings, enable "Enter Play Mode Options" but leave "Reload Domain" and "Reload Scene" disabled. (See Unity Manual - Configurable Enter Play Mode and Unity Blog - Enter Play Mode faster in Unity 2019.3.)
