    Hi, this thread on Data Oriented Technology Stack got me wondering about how this affects DOTS Physics.

    I use DOTS Physics, but I'm not using Entities at all. Will DOTS Physics (along with Burst, Jobs, Math, Collections) keep being compatible, or can we expect significant changes here?

    Cheers

    DOTS Physics is Entities.

    To be 100% precise, com.unity.physics package (DOTS Physics) depends on com.unity.entities package (DOTS Entities), so you can't have physics without entities.

    @milos85miki thanks, I had forgotten how these packages were tied together.

    It's a shame really as the physics engine is definitely useful without Entities. In our game we use the Entity field in RigidBody as a id into our own data-structures and it works great. We don't use the ECS at all.

    It would be great if Unity were a little more clear on the nature of the upcoming changes, but c'est la vie.
