-This topic is broadcast from the [[TransformComponent|ITransformComponent]] of an [[Entity]] whenever the transform's Position or Rotation value changes. If a transform contains child entities, their positions and rotations are also modified along with the parent's, and this broadcast is used to trigger lookups on a transform's children and their new values.
+This topic is broadcast from the [[ITransformComponent|TransformComponent]] of an [[IEntity]] whenever the transform loses or gains a child [[IEntity]]. Child loss can either happen by manual removal or child destruction. The payload contains two values; the child [[IEntity]] that was modified and a boolean value that signals whether the child [[IEntity]] was added (true) or removed (false). Child addition and removal is meant to be achieved by modifying the child's Parent value, rather than manipulating the parent's Children collection.
