High-Level steps to Use Physics for Bullets:

Number 01

Look through Unity DOTS Physics sample repo to find similar examples

Number 02

create a system that changes the material and destroys prefab entities from collision

Number 03

Add a dynamic buffer of stateful triggers on the entity prefab

FAQ

How do you make Rigid Bodies using DOTS Physics in ECS AR?

Since Unity Physics is purely based on DOTS, rigid bodies are represented with component data on the Entities. The simplified Physics Body and Physics Shape view that you have in the Editor is actually composed of multiple data components under the hood at runtime. This allows more efficient access and to save space for static bodies which do not require some of the data.

What are the main run-time components of DOTS Physics in ECS AR?

The main components are: PhysicsCollider, PhysicsVelocity, PhysicsMass, PhysicsDamping, PhysicsGravityFactor, PhysicsCustomTags. These components are read from to BuildPhysicsWorld then written to in ExportPhysicsWorld.

What are Physics Category Names in ECS AR?

Physics Category Names are how you can define what objects collide with each other and whether or not they raise events.

Haven’t begun learning Unity DOTS yet, and need to start at the very beginning?

If you haven't yet dipped your toes into learning Unity's new multithreaded Data-Oriented Technology Stack (DOTS), now is the time. You can start at the very beginning with Moetsi’s tutorial, which culminates in your very own deployable sample project. You’ll be guided by full workflows, code-alongs, videos, and GIFs along the way.
