Entity Hierarchy (parenting)

An entity with a parent will duplicate its parent's motion (move with it). An example would be parenting a dynamic light to a lamp prop so the light becomes part of the lamp and moves with it. A group of objects parented together form an hierarchy and essentially become one object.

To parent two objects together, type a name for the parent object in its Name key value. For the other object, set its Parent key value to that same name.

Only certain entities can have parents. For example, a prop_physics cannot because it is its own physics object. In this case, a prop_dynamic or prop_dynamic_override should be used instead.
