Detailed Description

template<typename HTag>
struct entttree::ParentConnection< HTag >

ECS component storing an entity's parent and sibling position.

This is the source of truth for parent-child relationships in a HierarchySystem. It lives on the child entity. The Position field determines the relative ordering among siblings.

Do not modify this component directly; use HierarchySystem's mutation API so that the internal children cache and signals stay consistent.

Template Parameters

HTag	Tag type identifying which hierarchy this connection belongs to.
