    Method AddBuffer

    AddBuffer<T>(Entity)

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

    Declaration
    public DynamicBuffer<T> AddBuffer<T>(Entity e)
        where T : struct, IBufferElementData
    Parameters
    Type Name Description
    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.

    InvalidOperationException

    Throws if this EntityCommandBuffer has already been played back.
