DOTS ECS enables you to build more ambitious games ECS for Unity 2022 editor tools GameObject-compatible authoring workflows Sunblink Entertainment - HEROish Fully supported ECS foundation Streamlined ECS workflows Flexible game architecture ECS for Unity enables seasoned Unity creators to build more ambitious games Streamlined workflows and a familiar authoring experience in the Unity Editor, compatible with GameObject ecosystems. Empowering development teams by eliminating most of the refactoring that would have been necessary with object-oriented architectures.

DOTS ECS enables you to build more ambitious games Electric Square - Detonation Racing Lienzo - Aztech: Forgotten Gods Stunlock Studios - V Rising Control and determinism Fully utilize your target device Made for massive data streaming Providing memory control and determinism by design, creating optimization opportunities at scale, and new game code possibilities based on determinism. Helping development teams maximize the performance of target platform hardware resources at the memory and CPU level. Offering an efficient data pipeline that enables streaming and rendering of complex, large-scale game experiences.

DOTS ECS enables you to build more ambitious games Big Rook Games - Hostile Mars StickyLock Studios - Histera Ramen VR - Zenith: The Last City Unprecedented simulation scale Large multiplayer games Rich and lively open worlds Scale to an unprecedented number of entities and ensure determinism. Process large physics simulations with Unity Physics or Havok Physics for Unity. Synchronize more data over the network, build games highly reliant on rollback and determinism, support more players, reduce development risk, and decrease iteration time. Push the boundaries and size of rich, persistent, open world experiences.

Future Plans

DOTS Roadmap → Entities and GameObjects Unification Consolidation of ECS workflows We're bringing GameObjects and Entities closer together to deliver data-oriented performance to all Unity projects. → Enabling open-world game creation ECS-based reworks of the Animation and Worldbuilding systems will enable more dynamic/scalable workflows, with unprecedented complexity at runtime. → Character and Vehicle Controllers The production-ready version of the ECS Character Controller is being prepared. We're also working on a robust controller for vehicles, enabling creators to easily build low-to-medium realism vehicles with ECS.

DOTS Roadmap → Unified Physics Backend Workflow Consolidation of physics workflows We're developing a unified authoring workflow that will allow you to switch your physics backend without needing to redo your project. → Enabling open-world game creation In the future, you'll be able to change the broadphase to operate incrementally using the PhysicsStepAuthoring and PhysicsStep Entities components. → Character and Vehicle Controllers We're also working on a new Collider.BakeTransform function that provides the ability to arbitrarily scale or otherwise transform any collider at runtime efficiently.

DOTS Roadmap Improving parallel scheduling and configuration → Out-of-the-box parallelism We’re investigating out-of-the-box parallelism of DOTS by enabling systems to run in parallel, whether or not they schedule jobs internally. → Optimizing dependencies between jobs We’re also investigating removing unnecessary dependencies between jobs coming from ECS systems which previously required manual intervention. → Improved job configuration controls We’re working on expanding the priority and control of how jobs run to prevent common issues, like unintentionally waiting on long-running jobs on the main thread.

DOTS Roadmap Unity Profiler improvements → New Profiler view We're developing a new Profiler view that will help you understand where your game is waiting, how job dependencies interact in the Job System, and the flow of your game’s data between ECS systems and jobs when using Entities.

DOTS Roadmap Improving Entities Graphics performance → DOTS deformation We are looking at is the support of DOTS deformation in order to provide a mesh deformation pipeline that is performant and scalable → Improved support and performance We’re working on improving the GPU performance (and current workflow) for a better, more seamless integration into the engine/SRPs. There will also be broader material support and URP support for Motion vectors.

DOTS Roadmap New education content → New e-book, samples, and more Extensives resources that explain the benefits and features of DOTS are in development. Upcoming samples will highlight additional Unity Physics use cases and a large-scale space battle simulation.

DOTS Roadmap Enabling cross-play multiplayer games → Multiplayer center → Multiplayer Play Mode → Dedicated Server optimizations → Improved deployment workflows → Multiplayer Services SDK → Netcode for GameObjects: Distributed → authority → Netcode Unification Our netcode tech stack is being simplified into a single solution that will deliver all the features you need regardless of gameplay style and requirements.
