Struct DynamicSharedComponentTypeHandle

A handle to a specific shared component type, used to access an ArchetypeChunk's component data in a job.

Namespace: Unity.Entities

Assembly: Unity.Entities.dll

Syntax

[NativeContainer]
[NativeContainerIsReadOnly]
public struct DynamicSharedComponentTypeHandle

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 DynamicSharedComponentTypeHandle, use GetDynamicSharedComponentTypeHandle(ComponentType). 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 Update(SystemBase) just before use.

If the component type is known at compile time, use SharedComponentTypeHandle<T>.

Methods

Name	Description
ToFixedString()	Returns the formatted FixedString "DynamicSharedComponentTypeHandle[type_name_here]".
Update(SystemBase)	When a DynamicSharedComponentTypeHandle 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.
Update(ref SystemState)	When a DynamicSharedComponentTypeHandle 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.
