AppendToBuffer<T>(Int32, Entity, T)

Appends a single element to the end of a dynamic buffer component.

Declaration
public void AppendToBuffer<T>(int jobIndex, Entity e, T element)
    where T : struct, IBufferElementData
Parameters
Type Name Description
Int32 jobIndex

A unique index for each set of commands added to the concurrent command buffer across all parallel jobs writing commands to this buffer. The entityInQueryIndex argument provided by Entities is an appropriate value to use for this parameter. You can calculate a similar index in an IJobChunk by adding the current entity index within a chunk to the Execute(ArchetypeChunk, Int32, Int32) method's firstEntityIndex argument.
Entity e

The entity to which the dynamic buffer belongs.
T element

The new element to add to the DynamicBuffer<T> component.
Type Parameters
Name Description
T

The IBufferElementData type stored by the DynamicBuffer<T>.
Remarks

At Playback(EntityManager), this command throws an InvalidOperationException if the entity doesn't have a DynamicBuffer<T> component storing elements of type T.

Exceptions
Type Condition
InvalidOperationException

Thrown if the entity does not have a DynamicBuffer<T> component storing elements of type T at the time the entity command buffer executes this append-to-buffer command.
