In Secret Neighbor (Unity engine with Photon networking), one player among the kids is secretly the Neighbor in disguise.

1. Identifying the Neighbor in Disguise:
Every player controller contains a networked role flag and transform state:

CPP

// Conceptual C# / Unity Component Layout
public class PlayerController : MonoBehaviourPunCallbacks {
    public PlayerRole currentRole; // Kid, Neighbor, Clown, Bagger, Leader, etc.
    public bool isTransformed;     // True if currently in true Neighbor form
    public float stamina;          // Current stamina [0.0 - 100.0]
    public Inventory inventory;    // Equipped keys & items
}

public enum PlayerRole {
    Kid_Bagger = 0,
    Kid_Leader = 1,
    Kid_Brave  = 2,
    Kid_Inventor = 3,
    Kid_Detective = 4,
    Kid_Scout = 5,
    Neighbor_Normal = 6,
    Neighbor_Clown  = 7,
    Neighbor_Butcher = 8
}

Even when the Neighbor is disguised as a regular kid, their networked

CPP

currentRole

integer is on the client.

2. Reading Colored Keycards (Red, Blue, Yellow, Green, Purple):
Keys scattered around the house derive from

CPP

KeyItem

or

CPP

InteractableKey

:

CPP

public class KeyItem : InteractableObject {
    public KeyColor keyColor; // Red, Blue, Yellow, Green, Purple, Basement
    public bool isCollected;  // True if in a player's inventory
}

Filtering out

CODE

isCollected == true

gives you the exact world positions of all remaining keys required to unlock the basement door!

Great breakdown! When rendering Keycard ESP with ImGui, color-coding each key by its enum value makes finding them instant:

CPP

ImU32 GetKeyColor(KeyColor color) {
    switch (color) {
        case KeyColor::Red:    return IM_COL32(255, 60, 60, 255);
        case KeyColor::Blue:   return IM_COL32(60, 160, 255, 255);
        case KeyColor::Yellow: return IM_COL32(255, 220, 40, 255);
        case KeyColor::Green:  return IM_COL32(60, 255, 100, 255);
        case KeyColor::Purple: return IM_COL32(200, 80, 255, 255);
        default:               return IM_COL32(255, 255, 255, 255);
    }
}

In Unity IL2CPP builds of Secret Neighbor, you can find all key instances using

CPP

Object.FindObjectsOfType<KeyItem>()

or caching them in a

CPP

std::vector

whenever

CODE

KeyItem.Start()

executes.

That is so interesting that the role enum is broadcast to all clients from the start of the match! Thanks for the explanation!
