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.
