What problem does it solve?

It solves the challenge of writing efficient Unity DOTS systems when the system shell needs managed resources, while the hot path still needs Burst-compiled job performance.

Core Features & Use Cases

• Managed SystemBase outer shell: Use SystemBase when you must hold managed references (e.g., event subscriptions, managed callbacks, or managed access patterns).
• Burst-compiled inner IJobEntity hot path: Delegate the compute-heavy work to inner IJobEntity structs that can be marked with [BurstCompile].
• Correct dependency chaining across ScheduleParallel: Use the SystemBase.Dependency auto-chaining behavior across sequential ScheduleParallel calls to avoid race conditions.

Use it when you have multiple jobs per OnUpdate that should share a dependency chain, but you cannot make the entire system purely ISystem because managed context is required.

Quick Start

Use the SystemBase shell for managed setup, then move all per-frame compute into Burst-compiled inner IJobEntity jobs scheduled from OnUpdate.
