# Unity ECS Skill Data-Oriented Technology Stack (DOTS) and Entity Component System development for Unity. ## Overview This skill provides capabilities for implementing high-performance gameplay systems using Unity's Entity Component System, Jobs System, and Burst compiler. ## Capabilities ### Entity Component System - Create IComponentData structs - Implement ISystem and SystemBase - Manage entity archetypes - Handle entity queries and batching ### Jobs System - Create IJob implementations - Implement IJobEntity for entity processing - Handle job dependencies and scheduling - Manage native containers ### Burst Compiler - Enable Burst compilation for jobs - Optimize with SIMD instructions - Profile Burst-compiled code - Handle Burst limitations ### Hybrid Workflow - Bridge ECS with GameObjects - Use companion components - Convert existing systems to ECS - Implement baking workflow ## Prerequisites - Unity 2022.3+ recommended - Entities package (1.0+) - Mathematics package - Burst package ## Usage Patterns ### Component Data ```csharp public struct MoveSpeed : IComponentData { public float Value; } public struct Velocity : IComponentData { public float3 Value; } ``` ### System Implementation ```csharp [BurstCompile] public partial struct MovementSystem : ISystem { [BurstCompile] public void OnUpdate(ref SystemState state) { float deltaTime = SystemAPI.Time.DeltaTime; foreach (var (transform, velocity) in SystemAP...
