Unity Entities
Unity DOTS' ECS package providing archetype storage, queries, baking, jobs, and Burst integration.
Why use it
It fits unit, projectile, and simulation hotspots exceeding traditional GameObject workflows.
Where it fits
Find engines, frameworks, code libraries, version control, and production automation.
What to check
Learning and debugging costs are high; do not mechanically rewrite everything as ECS, and licensing follows Unity terms.
