    Add all physx static collider to dots physics, possible.

    Yeah it's gonna be a manual thing. You need to look at physics shape conversion in DOTS, but also the BuildPhysicsWorld system. After you've done...

    Question Integration of 2D physics, Relation between Physics and Tiny

    Unity Physics that we speak of here is a 3D physics engine. You can emulate 2D behavior by freezing one axis via joints, but it's not a real 2D...

    Question Getting Error Attempting CollisionWorld.CastRay

    You need to declare CollisionWorld as [ReadOnly] in your job. That said, you have a bigger problem in this example - you are scheduling a job at a...

    CompoundCollider Filter Error Not Union Of Children

    There is a bug in the safety system and I think not setting the group index is actually what gets you past this (you get a group index of 0). :)...

    Why do trigger events require at least one non-static physics body?

    Yeah, it's not due to the fact that we need a body, it's an optimization thing. Let me try to explain. Trigger bodies are no different than any...
