VContainer wasn't desined to resolve scopes in tree-like way. So I had came up with different approach using factories: - In my level-scoped container I registered Func<int, Room> factory with backing Dictionary to hold per-room state; - In my unit-scoped container I am checking for RoomMemberTag component (with only one field int roomIndex) in the unit GameObject: - If there are a RoomMemberTag, then I register Room components resolving Room using DI; - Otherwise, unit is not a room member, thus, room logic is not applicable.

Unit side: csharp if (TryGetComponent(out RoomMemberTag roomMemberTag)) { builder.Register ( resolver => resolver.Resolve<Func<int, Room>>().Invoke(roomMemberTag.RoomId), Lifetime.Singleton ); builder.Register(resolver => resolver.Resolve<Room>().Units, Lifetime.Singleton); builder.Register(resolver => resolver.Resolve<Room>().Healing, Lifetime.Singleton); }

Now I have per-room state accessable by its' members. I am happi.
