Resolver

Resolver is a component that injects all the dependencies into its child components. You can specify where to get the dependencies from via the DependencySource setting.

Resolver follows the injection rules.

Resolver has a custom editor, allowing to see all the dependencies it will be able (or not) to resolve:

By default, Resolvers have negative execution order. This setting ensures injection takes place before Awake methods of MonoBehaviours. If needed, the execution order can be changed in the Project Settings/Script Execution Order menu.
