Child Game Objects Only Attribute

The ChildGameObjectsOnly attribute can be used on Components and GameObject fields and will prepend a small button next to the object-field that will search through all child gameobjects for assignable objects and present them in a dropdown for the user to choose from.

public Transform ChildOrSelfTransform;

public GameObject ChildGameObject;

[ChildGameObjectsOnly(IncludeSelf = false)]
public Light[] Lights;
