Method RegisterSingleton

RegisterSingleton<T>(EntityCommandBufferSystem, ref UnsafeList<EntityCommandBuffer>, WorldUnmanaged)

Every unmanaged Singleton that implements IECBSingleton must be registered by this function, at the end of its owner's EntityCommandBufferSystem.OnCreate method, in order to prepare the Singleton with the unmanaged data necessary for it to work from unmanaged code, without holding a managed reference to the EntityCommandBufferSystem. This Singleton component will be added to the system entity for this EntityCommandBufferSystem derived type.

Declaration

public static void RegisterSingleton<T>(this EntityCommandBufferSystem system, ref UnsafeList<EntityCommandBuffer> pendingBuffers, WorldUnmanaged world) where T : unmanaged, IECBSingleton, IComponentData

Parameters

Type	Name	Description
EntityCommandBufferSystem	system	The managed EntityCommandBufferSystem that owns the Singleton
UnsafeList<EntityCommandBuffer>	pendingBuffers	The list of command buffers in the managed System to append to
WorldUnmanaged	world	The world that this command buffer buffers changes for

Type Parameters

Name	Description
T	The unmanaged Singleton type, that corresponds to the managed EntityCommandBufferSystem subclass

RegisterSingleton<T>(EntityCommandBufferSystem, ref UnsafeList<EntityCommandBuffer>, WorldUnmanaged, string)

Obsolete. System entities are used for ECB component data, rather than entityName.

Declaration

[Obsolete("The entityName parameter is obsolete. System entities are now used for ECB component data.")]
public static void RegisterSingleton<T>(this EntityCommandBufferSystem system, ref UnsafeList<EntityCommandBuffer> pendingBuffers, WorldUnmanaged world, string entityName) where T : unmanaged, IECBSingleton, IComponentData

Parameters

Type	Name	Description
EntityCommandBufferSystem	system	The managed EntityCommandBufferSystem that owns the Singleton
UnsafeList<EntityCommandBuffer>	pendingBuffers	The list of command buffers in the managed System to append to
WorldUnmanaged	world	The world that this command buffer buffers changes for
string	entityName	The name of the entity.
