Remarks
Passing a type handle to a job automatically registers the job as a reader or writer of that type, which allows the DOTS safety system to detect potential race conditions between concurrent jobs which access the same component type.
To create a EntityTypeHandle, use ComponentSystemBase.GetEntityTypeHandle(). While type handles can be created just in time before they're used, it is more efficient to create them once during system creation, cache them in a private field on the system, and incrementally update them with EntityTypeHandle.Update just before use.
Methods
Method | Description |
|---|---|
| ToFixedString | Returns "EntityTypeHandle". |
| Update | When a EntityTypeHandle is cached by a system across multiple system updates, calling this function inside the system's OnUpdate() method performs the minimal incremental updates necessary to make the type handle safe to use. |
