Game.Prefabs.PlaceholderObjectElement

Assembly: Assembly-CSharp.dll
Namespace: Game.Prefabs

Type: public struct PlaceholderObjectElement : Unity.Entities.IBufferElementData

Base: System.ValueType (struct); implements Unity.Entities.IBufferElementData

Summary:
A lightweight ECS dynamic buffer element that stores a reference to an Entity used as a "placeholder" object for prefabs. The struct is marked with [InternalBufferCapacity(0)], indicating no inline storage for elements and that buffer memory is allocated separately. Use this element type when you need to maintain a list of placeholder Entities on an Entity via a DynamicBuffer (e.g., during prefab or placeholder management in the game's prefab system).

Fields

  • public Unity.Entities.Entity m_Object
    Holds the Entity reference for the placeholder object. This is the value stored per buffer element and typically refers to an Entity representing a temporary or placeholder instance related to a prefab.

Properties

  • None.
    This struct defines no properties.

Constructors

  • public PlaceholderObjectElement(Unity.Entities.Entity obj)
    Initializes a new buffer element with the provided Entity reference (sets m_Object = obj).

Methods

  • None.
    This struct contains only a field and a constructor; there are no methods defined.

Usage Example

// Assume 'entityManager' and entities already exist.
var entityWithBuffer = /* an Entity that should hold the buffer */;
var placeholderEntity = /* an Entity used as a placeholder */;

// Add the buffer to the entity if it doesn't exist, then add an element:
if (!entityManager.HasComponent<PlaceholderObjectElement>(entityWithBuffer))
{
    entityManager.AddBuffer<PlaceholderObjectElement>(entityWithBuffer);
}

var buffer = entityManager.GetBuffer<PlaceholderObjectElement>(entityWithBuffer);
buffer.Add(new PlaceholderObjectElement(placeholderEntity));
