DOTS-Hybrid-Simulation-Worlds

A framework for using FixedUpdate in a simulation world which is linked to a GameObject-based presentation layer.

How To

Each instance of the Bootstrapper class contains it's own world.

This handles simulation and presentation a little differently than the default Unity world:

Systems are set up to do presentation using GameObjects. Your custom Components should inherit from EntityMonoBehaviour instead of MonoBehaviour.

Prefabs and EntityArchetypes are managed in the Bootstrapper class as well. Utility methods for creation and destruction are provided to ease the management of the simulation and presentation sides of an object.

Add a GameObject with ResetDotsOnDestroy into your scene to clean things up when the scene transitions.

Remember to add UNITY_DISABLE_AUTOMATIC_SYSTEM_BOOTSTRAP to the Scripting Define Symbols in Project Settings > Player if you want to turn off the default world that Unity creates. This doesn't stop you from using any of the default systems but you will need to set them up in a Bootstrapper.

See the Example scene for more information.

Development Environment

Turn on .csproj generation for local packages to enable IDE analysis of package files.
