# children

The child entities that the entity manages.

## Declaration

```swift
@MainActor @preconcurrency var children: Entity.ChildCollection { get set }
```

## Discussion

Discussion An entity can have any number of child entities. Use the addChild(_:preservingWorldTransform:) method to add a child to an entity. Use the removeChild(_:preservingWorldTransform:) method to remove one from an entity. These methods automatically update the parent properties of the child entities.
