# didAddToEntity()

Notifies the component that it has been assigned to an entity.

## Declaration

```swift
func didAddToEntity()
```

## Discussion

Discussion Override this method in a component subclass if you need to perform game logic when the component is added to an entity. For example, if one component’s behavior depends on the presence of other components in the same entity, you can examine the entity’s components array in this method and take action accordingly.
