Method AddBuffer

AddBuffer<T>(int, Entity)

Records a command to add a dynamic buffer to an entity.

Declaration

public DynamicBuffer<T> AddBuffer<T>(int sortKey, Entity e) where T : unmanaged, IBufferElementData

Parameters

Type	Name	Description
int	sortKey	A unique index for each set of commands added to this EntityCommandBuffer across all parallel jobs writing commands to this buffer. The ChunkIndexInQuery provided by IJobEntity is an appropriate value to use for this parameter. In an IJobChunk pass the 'unfilteredChunkIndex' value from Execute(in ArchetypeChunk, int, bool, in v128).
Entity	e	The entity to add the dynamic buffer to.

Returns

Type	Description
DynamicBuffer<T>	The DynamicBuffer<T> that will be added when the command plays back.

Type Parameters

Name	Description
T	The IBufferElementData type stored by the DynamicBuffer<T>.

Remarks

At playback, if the entity already has this type of dynamic buffer, this method sets the dynamic buffer contents. If the entity doesn't have a DynamicBuffer<T> component that stores elements of type T, then this method adds a DynamicBuffer component with the provided contents. If the entity is destroyed before playback, or is deferred, an error is thrown.

Exceptions

Type	Condition
NullReferenceException	Throws if an Allocator was not passed in when the EntityCommandBuffer was created.
