Used on game objects or components. When used on a game object, it checks if the game object has a component of the required type. When used on a component, it checks if the game object it is attached to has a component of the required type.

If you want to use it on fields that are nested inside serialized structs or classes you need to use the AllowNesting attribute.

    [RequiredType(typeof(IRequiredTypeTestInterface), typeof(IRequiredTypeTestInterface2))]
